Necessity of reconstruction

Why is the baseball stadium is being rebuilt at the site of the rugby facility while the rugby facility is being rebuilt at the site of the baseball stadium?
Would it be possible to renovate the baseball stadium and rugby facility at their current locations?
The redevelopment project will be executed in phases with the aim of minimizing the durations of sporting event interruption imposed for the sake of carrying out construction, while also addressing a range of concerns particularly those associated with deteriorating facilities of Jingu Stadium and Prince Chichibu Memorial Rugby Stadium.
Were the facilities to be rebuilt at their same locations, it would not be possible to host professional and amateur sporting events for several years. As such, we have accordingly opted for rebuilding to be carried out in phases taking into account the impact on sports promotion particularly in regard to ensuring continuity of sporting events.
Please also refer to the briefing materials and video available on this website for additional details on prevailing challenges with respect to each of the facilities.

Would it be possible to renovate Jingu Stadium at its current location utilizing the former site of Jingu No. 2 Stadium?
Also, was the seismic reinforcement work completed in the past insufficient?
We explored the possibility of renovating the facility in a manner that would have involved utilizing the former site of Jingu No. 2 Stadium. However, we ultimately opted for the current redevelopment plan, which entails rebuilding the facility in phases. Our rationale is that only certain features lacking in the current baseball stadium could be added were we to carry out construction in the midst of ongoing sporting events. Also, we would not be able to address issues inherent with respect to the current baseball stadium itself.
As such, this project entails plans not only for upgrading the sports grounds and spectator seating, but also various other improvements that include barrier-free facilities and enhancements to pedestrian and vehicular traffic flows. Meanwhile, in accordance with laws and regulations, we will also update aspects of the facility that it had not been possible to address through the previously completed seismic reinforcement work.
Koshien Stadium is undergoing renovation at its current location. Why is that approach not possible with respect to Jingu Stadium as well?
What makes the Koshien facility different from Jingu Stadium?
We conducted actual on-site inspections of Koshien Stadium and found that it differs from Jingu Stadium in that Koshien Stadium offers various prerequisites necessary for construction, particularly in terms of it having an operating environment that makes it possible to come up with a viable timeline for construction and in terms of its total site area and floor space. Although, sections of the current baseball stadium have undergone seismic reinforcement work and work to make it barrier-free for operational reasons, we ultimately deemed that the substantial on-site renovation of Jingu Stadium at its current location would not fundamentally solve its current issues and that it needs to be rebuilt for the next century.

Specifically, it will need elevators or escalators to be installed to make it barrier-free, but space in the current stadium is limited. Also, pedestrian and vehicular traffic flows are not separated, but the space around the circumference of the stadium is narrow, so it would not be practical to fix this issue through new work.

Please refer to the following materials for information on issues Jingu Stadium is currently facing.
Current Issues at Jingu Stadium (Japanese only):https://www.jingugaienmachidukuri.jp/pdf/240216_jingugaienmachidukuri-stadium.pdf
For further details, please refer to our explanation on reasons why it is not possible to rebuild and renovate Jingu Stadium at its current location as outlined in the Informational Video about the Jingu Gaien District Urban Redevelopment Project

Why is it necessary to rebuild Prince Chichibu Memorial Rugby Stadium?
Prince Chichibu Memorial Rugby Stadium has been subject to considerable deterioration given that it was built 76 years ago. It has long needed to adopt universal design and comply with diverse needs. Refer to the following documents regarding prevailing issues regarding the stadium.
Current status of Prince Chichibu Memorial Rugby Stadium (deterioration of facilities and equipment, Japanese only): https://www.jingugaienmachidukuri.jp/pdf/230921_jingugaienmachidukuri-rugby.pdf
The notion of addressing these concerns has given rise to the need for planning facilities in a manner that takes into account certain considerations. This includes various facility-related requirements such that include securing rooms and concourse space necessary for carrying out sporting events, evaluating dimensions of spectator seating, and ensuring sightlines in terms of views from spectator seating. It also includes safety considerations such as those that involve ensuring smooth spectator flow. This redevelopment project enlists this phased rebuilding approach in order to make such improvements possible.
Is there a need for the continued use of a rugby and baseball stadium to the extent that they require rebuilding?
Under the Jingu Gaien District Urban Redevelopment Plan, this district will bring together many of Japan’s representative sports facilities to form a center of activity for both citizens and athletes to enjoy sports. The Tokyo in 2020 plan (formulated in December 2011) called for the district to be redeveloped as a sports cluster, to create a lively area where people can gather and be active. Our plan for the district is in line with these plans.

Facilities to be eliminated in the future

What facilities are planned to be built? Will there be newly created facilities?
Whereas the project entails elimination of Jingu No. 2 Stadium, golf training facility, rubber baseball ground, batting cage facility, and futsal courts, are there any plans to set up areas for children and the general public to engage in sports and other recreational activities?
The project will involve upgrading both Jingu Stadium and Prince Chichibu Memorial Rugby Stadium, while also developing numerous plazas and open spaces to serve as zones for relaxation. Additionally, we aim to develop an appealing urban location where everyone is able to readily visit and enjoy sports and cultural events. It will feature elements such as new accommodation facilities, commercial space, and offices, with each of the facilities connected by pathways and decks thereby providing greater pedestrian convenience and safety.
Please access this website page for details regarding distinctive characteristics of each facility.

The picture gallery front lawn area, which currently serves as the site of the rubber baseball ground available for use only by those playing baseball, will be developed into a plaza location accessible to everyone, thereby upholding the site’s original concept of serving as an accessible outer garden location.
As such, given the project’s limited space for facility development, three facilities (the golf training facility, rubber baseball ground, and batting practice area) will be eliminated, but the project will provide for new settings that include the New Prince Chichibu Memorial Rugby Stadium (tentative name), the plaza in front of the picture gallery, Central Plaza, and indoor ballgame rooms planned for the lower floors of mixed-use building B. Under the plan, these facilities will be used as activity spaces to provide even wider access to the general public for not only baseball and soccer, but also for various other sports, exercise and recreational activities, depending on the occasion. Also, the indoor ballgame rooms will be designed for a wide range of uses including club activities, tournaments, and events that involve interacting with athletes. The specific operational approach and usage have not yet been decided, but will be discussed in the future.
Will the Japan Sport Council tennis courts be relocated or will they be eliminated?
It will be necessary to do away with the Japan Sport Council tennis courts in order to secure space required by relevant laws and regulations with respect to greenery and other such matters associated with rebuilding of the rugby facility. But there are plans to have tennis courts available for use by the general public under the Jingu Gaien District Urban Redevelopment Project.
The Japan Sport Council will, through the relocation and reconstruction of the Prince Chichibu Memorial Rugby Stadium, contribute to the formation of a world-class sports cluster as stated under the Tokyo Metropolitan Government’s high-level plan.
And the Jingu Gaien District Urban Redevelopment Project is not simply for large-scale sports facilities, environments and plaza spaces will be prepared where everyone can enjoy sports. Please also refer to this Q&A for more information on the planned facilities.
Why will the rubber baseball grounds be eliminated?
The rubber baseball grounds will be eliminated per the facilities layout plan of the overall urban redevelopment project.
The redevelopment project involves plans to restore the plaza space to how it was when Jingu Gaien was first developed, but in a format and appearance suited to the contemporary times. As such, plans call for redeveloping the plaza in a manner that allows for unrestricted access to anyone who may visit Jingu Gaien, rather than fencing off the area, in order to uphold the site’s concept of serving as an accessible outer garden location.
If the rubber baseball grounds are to be removed, where will the pre-game practice for professional baseball players be held post-redevelopment? If the new baseball stadium is to be used for pre-game practice, won’t this reduce opportunities for non-professional baseball players to use the stadium and make it difficult for students and professionals to share the field?
We will discuss the matter of pre-game practice for professional players at the new baseball stadium with the respective organizers to ensure that students and professionals can share the field.

Construction work

Could you provide specific details regarding the construction plan, including considerations such as sites for evacuation should a disaster occur during the construction period, ensuring safety particularly with respect to construction vehicles, and securing play areas for children?
Construction under the redevelopment plan will be carried out on the basis of individual sites associated with each of the facilities. As such, at no time will the entire redevelopment area be unavailable for use. Meanwhile, space necessary for use of the location as an evacuation site during construction will be secured.

Specific details regarding construction contractors for each of the facilities are yet to be determined. In regard to construction vehicles, however, main entry and exit points are to be located on the east, west, and south sides of the redevelopment site taking into account conditions of the surrounding roadways. We anticipate direct entry and exit from the peripheral roadways. We will implement traffic management to prevent situations involving temporary clustering of construction vehicles. This will involve streamlining vehicle schedules to ensure smooth reception of vehicles and providing rigorous guidance to drivers in order to minimize waiting times and parking on roadways.
We have also conducted surveys, forecasts, and evaluations as part of our environmental impact assessment report with respect to noise, vibration and other such effects on the environment. Please refer to relevant pages of that report for further details.
Construction plan (Japanese only): https://assess-toshokohyo.metro.tokyo.lg.jp/uploads/web_public/357_jinngugaien/06/06202235702.pdf

When undertaking construction with respect to each of the facilities, we will assign top priority to safety in construction planning to minimize inconvenience to all concerned. We will also examine specific details with respect to each of the facilities and will furnish preliminary explanations to those located in the vicinity of the project prior to submission of building permit applications through forums such as construction briefing sessions held pursuant to ordinances for preventing conflicts related to medium- and high-rise buildings.
Could you explain measures you will take to address construction delays potentially caused by major earthquake or other such contingency?
Regarding the construction schedule, we released a tentative schedule upon our receipt of approval for project implementation from the Tokyo Metropolitan Government in February 2023. In the event of significant changes to this schedule, we will promptly undertake the necessary procedures and provide notification. While delays attributable to natural disasters and other such force majeure events may be unavoidable, we will handle such contingencies appropriately.
When and how will you proceed with construction of the underground passageway connecting Tokyo Metro Gaienmae Station to the office building basement?
Construction of the underground passageway at Gaienmae Station is scheduled to take place withing the timeframe of the overall redevelopment project. Although specific dates have yet to be determined, we have been engaging in discussions with Tokyo Metro Co., Ltd. regarding potential impact on use of Gaienmae Station and are otherwise considering plans to ensure access and safety with respect to the station’s entrances and exits. During the construction period, we will continue to refine our plans in seeking to avoid imposing inconvenience on those using Gaienmae Station.
The redevelopment project enlists plans for connecting the basement of the office building with the underground passageway of Gaienmae Station on the Ginza Subway Line, thereby enabling access to ground level in the proximity of Aoyama 2-chome intersection via the underground passageway of the office building. The timeline for construction of the office building encompasses construction involving the underground passageway located within the office building. We will provide further explanation regarding the construction schedule to relevant parties during the construction phase.
Could you provide details on aspects of the underground infrastructure such as depths, diameters, locations, and construction methods?
Approximate locations of the individual pipes comprising the underground infrastructure have been presented with the drawings we submitted upon approval of construction. Decisions on depth and diameters of pipes will be made as the design progresses going forward. As for construction methods, we plan to obtain roadway access permits for each of the facilities and conduct pipeline construction work that will involve excavating part of the roadway.
Please remove the temporary construction enclosures around the Kenkoku Kinen Bunko forest.
Why is the temporary enclosure necessary?
The temporary enclosures are set up particularly in preparation for tree transplantation for the purposes of preventing entry by unauthorized individuals, reducing the impact of noise on the surrounding area, and preventing dust and materials from leaving the construction site. It would no longer be possible to ensure the safety of people passing by the site if the enclosures were removed.
To what extent will the underground framework of the new baseball stadium be excavated?Also, what is the expected depth in meters of the building piles?
We plan to excavate the side with the rows of ginkgo trees to a depth of around 3 to 4 meters* while taking into account structural considerations, such as flat foundations.
* In the environmental impact assessment report, the excavation depth is described as around 2 meters. We plan to submit a notification of change to this plan, as we decided to extend the distance from the sidewalk curb of the gingko trees to the underground framework of the new baseball stadium by around 10.3 meters to approximately 18.3 meters, and the actual depth and location of excavation will be determined going forward as specific plan details of the new baseball stadium are considered.

The building piles are expected to be approximately 40 meters below ground level, but details, including construction of the base portion, are still under consideration.
Did you plan to start removing trees on the night of October 25, 2024, when you receive removal approval from Shinjuku City?
Regarding the transplantation and removal of a portion of trees under the Jingu Gaien District Urban Redevelopment Project, after receiving approval based on Tokyo Scenic District Ordinance in February and September 2023 and October 2024, preparations for the transplantation and removal of trees with a height of 3.0 meters or taller started from October 28, 2024.
Please refer to the following release (Japanese only):https://www.jingugaienmachidukuri.jp/pdf/jingugaienmachidukuri_news_2024102801.pdf
The transplantation and removal of trees started in October 2024, but what procedures have been carried out in the lead up to this?
The project’s plan regarding greenery included the submission of an environmental impact assessment report in January 2023, which was then disclosed and made available for public viewing, and environmental impact assessment procedures have been carried out for each stage of the project. Following this, in September 2023, we received the “Submission of request regarding the conservation of trees in the redevelopment project of the Jingu Gaien District ” from the Tokyo Metropolitan Government. We provided our response to this request in September 2024 and the revised content and follow-up survey were reported at a meeting of the Tokyo Metropolitan Government’s Environmental Impact Assessment Council held in October.
Additionally, regarding the transplantation and removal of a portion of the trees, after receiving approval based on Tokyo Scenic District Ordinance in February and September 2023 and October 2024, preparations for the transplantation and removal of trees with a height of 3.0 meters or taller started from October 28, 2024, and work is being carried out appropriately in accordance with procedures stipulated by laws and regulations.
It seems like there is currently litigation occurring regarding the removal of trees in the Jingu Gaien District, but isn’t the very act of removing trees itself a problem?
The current removal of trees is being carried out under approval for tree felling based Tokyo Scenic District Ordinance received from Shinjuku City. While we recognize that there is litigation against the city as you mentioned, the project is carrying out work in an appropriate manner after following the procedures stipulated by various laws and regulations, as described in this Q&A.
What impact will the September 2024 plan revisions have, such as changes to the scheduled completion date?
The overall schedule will be examined going forward.

Impact on the surrounding environment

What is the impact of the construction of mixed-use building A, mixed-use building B, the office building and the new baseball stadium on the surrounding area in terms of wind and sunlight? How about the impact of the construction of those buildings on the new baseball stadium in terms of wind and sunlight?
Upon having conducted surveys, forecasts, and evaluations regarding wind for the environmental impact assessment report, our findings of wind tunnel experiments revealed the likelihood of the wind environment remaining at levels equivalent to current levels even after construction has been completed as a result of measures we will take to address building-related winds such as wind barriers and windbreak planting. We will also conduct follow-up surveys after construction of buildings has been completed. This will entail once again measuring actual wind conditions and implementing new measures if the reality differs from forecasts.

Simulations and other investigations regarding the impact of wind with respect to the new baseball stadium plan suggest that effects of wind will not substantially hinder baseball play. Going forward, we will persist in considering approaches to creating comfortable spectator settings in conjunction with enhancing designs of the new baseball stadium plan. We will also continue to explore options with respect to climate change measures above and beyond those related to the new baseball stadium plan.

Moreover, given our awareness of the challenges posed by strong winds in the current redevelopment area, we will explore measures for improving the wind environment in conjunction with efforts to enhance the design.
We have also conducted surveys, forecasts, and evaluations regarding wind and sunlight as part of our environmental impact assessment report. Please refer to relevant pages of that report for further details.

Will the construction of various structures, such as high-rise buildings (new office building), the new baseball stadium, and the new rugby facility affect the visual aesthetics of the location?
Regarding visual aesthetics of the location, we seek to preserve Jingu Gaien’s distinctive scenery long cherished by many. To such ends, we will engage in initiatives that entail conserving the Four Rows of Ginkgo Trees and revitalizing the landscaping of the plaza in front of the picture gallery. When constructing the buildings, we will aim to minimize any overwhelming presence of the structures and will furthermore seek to harmonize the structures with the abundant greenery of the surroundings.

We have presented details on the visual impact on the landscape in our environmental impact assessment report. Please refer to the relevant pages of that document in which we have included forecasts and evaluations that include views from distant locations. We will proceed with construction based on current plans, which have gained approval with respect to the project in terms of factors such as general plans for building layout and building volume. Meanwhile, we will proceed with design and other such considerations while factoring in visual impact on the surroundings given that building exteriors and other such considerations will be subject to review going forward. We have no virtual reality renderings or such documentation in that regard available to the public at this point in time, but we will take your opinions into consideration.
Visual impact (Japanese only): https://assess-toshokohyo.metro.tokyo.lg.jp/uploads/web_public/357_jinngugaien/06/06202235716.pdf

We also plan to develop settings for relaxation outside of the area slated for high-rise building construction. We intend to have the plans encompass creation of open spaces that will be widely available to the general public, such that include the Central Plaza and the plaza in front of the picture gallery.
Will there be an assessment by an independent third party, not only public agencies, to evaluate the impact of new buildings in terms of visual aesthetics and their overwhelming presence?
Regarding the assessment of the project’s impact in terms of visual aesthetics and the overwhelming presence of buildings, as explained in the Q&A regarding “Visual impact of new structures,” forecasts and assessments have been conducted in accordance with the Tokyo Metropolitan Government’s Environmental Impact Assessment Ordinance.
The environmental impact assessment report was discussed several times by the Environmental Impact Assessment Council, which comprises approximately 20 members, including academic experts with technical expertise, and was submitted after incorporating opinions received during the discussions.
In addition, Tokyo Metropolitan Government and Tokyo Ward landscape councils, which also include academic experts among their members, are discussing the project in accordance with landscape ordinances, etc.
What are your views on concerns that the buildings will have an overwhelming presence given their proximity to the new rugby facility and the National Stadium?
Although the new rugby facility building will be approximately 55 meters in height, it seems to me that the height of the structure is unlikely to be lower than that of the National Stadium given that the ground level of the new rugby facility is higher than that of the National Stadium. As such, how do you plan to minimize the sense of the building’s overwhelming presence?
Also, is the height of the new rugby facility building 46.15 meters as is stated in your other information?
We have conducted predictive evaluations at points on public roadways adjacent to the rugby facility and the National Stadium with respect to the degree of change regarding any overwhelming presence of the buildings due to their proximity to the new rugby facility and the National Stadium. Our findings are available in the environmental impact assessment report. We will plant tall trees and other greenery in coordination with pedestrian traffic flows at the planned official web site and its vicinity. We will otherwise strive to minimize the sense of overwhelming presence of the planned buildings under our plans for landscaping that strikes a balance in alignment with features of the district. For specific details, please refer to the environmental impact assessment report available on the Tokyo Metropolitan Government website, particularly pages 440, 442 (location 3), 464, and 467.
Visual impact (Japanese only): https://assess-toshokohyo.metro.tokyo.lg.jp/uploads/web_public/357_jinngugaien/06/06202235716.pdf

As you pointed out, the ground level of the new rugby facility is higher than that of the of the National Stadium and the new rugby facility building height is approximately 55 meters, as stated in the project plan documentation and environmental impact assessment report released when construction was approved. We are reviewing the facility plans in part by conducting predictive evaluations carried out to minimize its sense of overwhelming presence through measures that include setting back sections of the wall surfaces.
Going forward, we will continue to place consideration on visual aesthetics and prospects for reducing the sense of overwhelming presence during the design and construction phases.
Also, the building height of 46.15 meters was a proposed height suggested by the private finance initiative (PFI) operator associated with the new rugby facility.
In September 2024, we furthermore announced that the height of the new rugby facility has been changed to approximately 48 meters. We will carry out the various procedures necessary in this regard going forward.
【NEW】 Could you please discuss the acoustic environment following the construction of sports facilities and other structures?
First, let me first address noise from the new rugby facility. Because the new rugby facility will be an all-weather stadium, it will have a lower noise level than the Prince Chichibu Memorial Rugby Stadium. In addition, the project will comply with all relevant laws and regulations when operating the new rugby facility.
For information about noise from the new baseball stadium, please refer to this Q&A.
For information about noise during the construction period, please refer to this Q&A.
For details on noise during and after construction, please consult the environmental impact assessment report, where the noise is predicted and assessed, via the URL below. (Japanese only)
https://assess-toshokohyo.metro.tokyo.lg.jp/uploads/web_public/357_jinngugaien/06/06202235705.pdf
Does the new baseball stadium have a dome? What are your expectations regarding noise from the new baseball stadium? Also, what measures you are considering in that regard? Are you concerned that views expressed by neighborhood residents might potentially interfere with holding games and other events? Also, do you intend to address issues of vibration?
Please refer to this Q&A for an explanation of why we have opted for an outdoor stadium design with respect to the new baseball stadium. Noise levels from residential areas nearest the new baseball stadium will meet the 55 decibels at ground level (1.2 meters) environmental standard. However, forecasts of noise levels at the height of the grandstands of Jingu Stadium (approx. 11 meters) indicate that noise levels will increase by around 4 decibels relative to current noise levels during professional baseball games, thereby reaching a predicted level of 62 decibels. This decibel measurement has been calculated taking into account noise attenuation based on distance from a measurement of 83 decibels taken from the uppermost tier of the baseball stadium during games of the Tokyo Yakult Swallows.
Certain self-imposed rules for organizers in terms of operating events are also implemented even at the current baseball stadium. This includes sound restrictions with respect to time of day as well as number and types of sound sources. It also includes specifications for maximum decibel levels at the uppermost tier of the baseball stadium. At the new baseball stadium, we will also continue implementing situation-specific noise reduction measures and consider ways of operating operational methods to achieve a comfortable spectating environment, taking into account the impact on the neighborhood. Moreover, concerted efforts will be made to ensure advance notification of events.
As for the matter of vibration, no such issues have arisen in the course of operating the current baseball stadium thus far. However, we will look into the matter of vibration and other such concerns pertaining to the new baseball stadium when drawing up detailed plans going forward.
Have you calculated temperature changes that will result from removing trees for the sake of site development and increasing the number of buildings?
At this point in time, we do not plan to calculate temperature changes. However, we will take action from the perspective of mitigating heat in terms of contributing to measures against the urban heat island effect in the urban center. This will involve reducing surface area of asphalt pavement, artificial turf and other such surfaces within the site, and will also entail increasing landscaped area containing lawn, trees and other such greenery to the extent possible.
Could you provide current and post-redevelopment population estimates?
Would you also provide comparative figures in terms of categories that include day and night, with and without events, and weekdays and weekends? Also, please explain measures to tackle congestion at Gaienmae Station.
Simulations carried out with respect to the redevelopment project in terms of work arrangements and the presence of offices indicate an overall increase in the workforce population of approximately 13,000 people across each of the facilities. The seating capacity of the new baseball stadium is anticipated to be around 32,000, but as details of the new stadium design are yet to be determined, it is possible that this number will increase or decrease in accordance with future considerations.

Furthermore, on the basis of estimated number of employees and other such metrics, we have calculated traffic volumes, service levels, and other such estimates with respect to weekdays, weekends, and during events at various locations around the planned site, including peripheral roadways and pedestrian zones. Meanwhile, on a five-tiered rating scale, we seek to achieve the top “A” ranking across all locations on weekdays and weekends, and we seek to achieve an “A” or “B” rankings during events.

Additionally, in regard to increased congestion at the station accompanying the increase in population, we are cooperating with Tokyo Metro Co., Ltd. with respect to measures such as having more ticket gates installed and wider passageways at Gaienmae Station. The redevelopment project also includes plans for connecting the basement floors of the office buildings with the underground passageway leading to Gaienmae Station on the Ginza Subway Line, thereby enabling access to ground level in the proximity of Aoyama 2-chome intersection via this underground passageway.

We will take into account the increase in number of visitors throughout the development in the course of exploring options particularly with respect to plans for safe pedestrian and vehicular traffic flows in a manner that does not impose inconvenience on those accessing facilities and nearby residents.
Have you come up with forecasts on how lighting installed at the new baseball stadium will impact the surrounding area? Will drawings be released that show the shape and position of lighting for night games? There are concerns about the impact that the lighting could have on cars traveling along Aoyama Street, and offices and housing in the surrounding area. Is this being considered by the Environmental Impact Assessment Council?
As of the present stage, we have not forecast the impact of light damage from lighting on the surrounding area, and it is not targeted in the environmental impact assessment*, but we will proceed with efforts to review lighting to be installed going forward, taking into account its impact on the surrounding area.
Lighting is being considered, so we don’t plan to release drawings as of the present time, but when detailed consideration make progress, we will consider incorporating it into renderings, etc.
* The impact of the new baseball stadium lighting as an architectural structure, and its impact on the Four Rows of Ginkgo Trees in terms of sunlight and scenery, specifically taking into account its height and color, etc., is being considered, as stated in the environmental impact assessment report.
There is apparently a proposal to set back the new baseball stadium to preserve the Four Rows of Gingko Trees, but in the event of such changes to the plan proposal such as in the shape of the new baseball stadium, could you tell us how the environmental impact assessment will proceed in the future?
In September 2024, we decided to set the distance from the sidewalk curb of the Four Rows of Ginkgo Trees to the underground framework of the new baseball stadium to approximately 18.3 meters (the “Setback Width”), thereby extending the distance by approximately 10.3 meters from approximately 8.0 meters under the original plan.
Given that there will be changes, etc., in the shape of the new baseball stadium as indicated in the environmental impact assessment report, if this leads to any changes in the content of the forecast or assessment, a re-forecast and assessment will be conducted and notification of changes submitted to the Tokyo Metropolitan Government.
According to the plan revisions announced in September 2024, the distance between the new baseball stadium and the Four Rows of Ginkgo Trees will be approximately 18.0 meters. Will this cause any sunlight issues due to the new baseball stadium or high-rise buildings?
The investigation, predictions, and evaluation regarding sunlight in the environmental impact assessment report are based on a setback width of approximately 8.0 meters and there were no issues in spring, summer or fall. There was a section where some shadows were elongated in winter, but this was checked by a tree doctor and others and it was confirmed that as ginkgo trees shed their leaves, they photosynthesize less in winter so the shadows during this period will not have a significant impact on tree growth. We will reassess this impact in accordance with the increased setback width and provide an explanation within the environmental impact assessment process.

Jingu Stadium

What sort of considerations have you made with respect to the height of protective fencing at the new baseball stadium?
We are currently evaluating options regarding height of protective netting based on fly ball data from publications and other such publicly available sources. In determining appropriate heights of protective netting, we will continue to prioritize safety taking into account prevailing considerations that include findings from batting simulations.
What changes are planned for Jingu Stadium? Why an outdoor stadium? And would you provide information about the details of the new baseball stadium, such as will seating capacity increase?
The new baseball stadium will be built where Prince Chichibu Memorial Rugby Stadium is currently located. The plan is to realize an outdoor stadium that showcases the unique appeal of this redevelopment by enabling visitors to experience the abundant nature of the district, such as the Four Rows of Ginkgo Trees, is an aim towhile also carrying on the history of Jingu Stadium.
With the construction of a hotel in the area behind the backstop, the stadium will also be connected via pedestrian deck to a mixed-use building equipped with commercial space.
We estimate a seating capacity of approximately 32,000 people. However, that number may be subject adjustment upon further review going forward given that specifics of the new baseball stadium design are yet to be determined. We plan to reduce the number of seats in the outfield stands compared to the current baseball stadium. This decision is to be made upon reviewing plans for the entire baseball stadium while reducing the size of the outfield spectator stand zone taking into account factors such as shade and visual considerations.

We will address various challenges going forward, such that will include devising a structural layout that allows for rebuilding to be carried out in phases, ensuring barrier-free traffic flows, setting up spacious concourse areas and passageways, making the seats more comfortable than in the current baseball stadium but still ensuring a sufficient number of seats, and separating pedestrian and vehicular traffic flows, and setting the stadium apart from adjacent facilities and the Four Rows of Ginkgo Trees. Meanwhile, we will also continue to review options to ensure plans for a facility that is appealing as a baseball stadium, particularly in terms of enabling visitors to enjoy a variety of spectator options through the introduction of new seating and different zones.
The proposed revisions released on September 9, 2024, said that the distance from the sidewalk curb of the rows of ginkgo trees to the underground framework of the new baseball stadium will be extended to 18.3 meters, but how will this impact the new baseball stadium?
Details regarding the new baseball stadium design are yet to be determined but parts of the facility plans will be changed. In accordance with the setback plan in the proposed revisions, we will advance considerations while aiming to realize better game environments for both players and spectators.
Will there be any changes as the result of widening the setback width of the new baseball stadium, such as the field becoming smaller or the hotel section being removed?
Details regarding the design are still under consideration, but adjustments to the new stadium are being made to ensure better environments for both spectators and players. There are no plans for any major changes to the purpose of the stadium, such as the removal of the hotel, or for any change in shape.
As rebuilding is to be carried out in phases, confirmed details will be announced at the appropriate phase.
What are your plans in terms of features such as stadium floodlight towers and the outfield scoreboard?
I watched the promotional video on the new baseball stadium and it looked like the screen is facing outward. What are your considerations for the impact on the surrounding area and scenery? Are the architectural renderings of the facility sufficient?
We are reviewing plans for the stadium floodlight towers that take visual aesthetics into account in terms of reducing the number of large functional structures by integrating lighting fixtures at the tops of the towers with large visual displays at the bottoms of the towers. As for the outfield scoreboard, we will review options regarding the scoreboard height necessary to ensure an appropriate environment for game play.
Meanwhile, the architectural renderings currently posted to the project website and the new baseball stadium video released at Jingu Stadium serve only as conceptual illustrations of facilities upon completion. As such, they are subject to change accompanying detailed design updates going forward. In addition, we will consider the floodlight towers and screens, etc. to be installed going forward while taking into account the impact on the surrounding area and scenery.
Would you provide details on the barrier-free elements being introduced at Jingu Stadium?Are you planning any inclusive design initiatives?
Given that specifics of the new baseball stadium design are yet to be determined, we have not yet made decisions on considerations such as the specific number and locations of restrooms and other facilities for people with disabilities, as well as spectator zones for wheelchair users. We have also not yet made decisions regarding consideration guidelines on inclusive design.
However, we will proceed with review to ensure compliance with various standards that include barrier-free laws, barrier-free ordinances, and urban development ordinances with a focus on social welfare.
Would you provide details on the traffic flow at the new baseball stadium?
Also, how many pedestrian entrances and exits are planned for the new baseball stadium?
The new baseball stadium will have several entrances and exits that ensure pedestrian flow to the decks planned for installation to separate pedestrian and vehicular traffic The new Jingu Stadium will have several pedestrian decks that separate pedestrian and vehicular traffic (the number of “gates” corresponding to entrances 1-18 of the current baseball stadium has not been determined at this stage).At the new Jingu Stadium, pedestrian traffic flows will be separate from vehicular traffic flows, with the main pedestrian entrances and exits to be positioned at two locations, one in the direction of Aoyama 1-chome and the other in the direction of Gaienmae. The pedestrian decks leading to the entrances and exits of the new baseball stadium building will be at least 10 meters in width. The pedestrian deck leading to the entrances and exits will be at least 10 meters in width. Moreover, the site will offer smooth access in the direction of Gaienmae Station and Aoyama-itchome Station. It will also offer smooth traffic flows via the north-south deck and Central Plaza, with respect to routes to the north toward locations such as Kokuritsu-Kyogijo Station, Shinanomachi Station, and Sendagaya Station.

For information on pedestrian and vehicular traffic flows determined as of this point in time, please refer to “Futurebaseball stadium” on page 25 of the briefing materials available on this website and also refer to relevant segments of our explanatory video content.

Although specifics of the new baseball stadium are yet to be determined, we will review options in a manner that takes into account feedback with respect to plans for ensuring pedestrian safety, particularly in terms of specific plans for the location and number of gates, traffic flows from each stadium seat and evacuation routes. Meanwhile, the architectural renderings currently posted to the website and elsewhere and videos of the new baseball stadium shown at the current baseball stadium serve only as conceptual illustrations of facilities upon completion. As such, they may change along with design updates going forward.
The current Jingu Stadium serves as a rare example of a Japanese professional baseball stadium equipped with a pitcher’s bullpen as part of the baseball field.
Where is the bullpen likely to be located in the new baseball stadium?
We will review options regarding the location of the bullpen during the design process going forward.
What benefits does rebuilding the stadium offer to the Tokyo Yakult Swallows, who currently use Jingu Stadium as their home field?
Have you begun discussions or other communication with the Yakult baseball team?
Would you also provide details on the involvement of the Yakult baseball team in the new baseball stadium project?
This project entails plans not only for upgrading the sports grounds and spectator seating, but also various other improvements that include barrier-free facilities and enhancements to pedestrian and vehicular traffic flows. We seek to ensure safe, secure and comfortable access to the stadium by addressing various concerns currently encountered not only by the Tokyo Yakult Swallows but also by organizers and athletes who use the stadium.
Moreover, we plan to carry out the design process while continuing to engage in discussions with the Yakult baseball team.
What are your plans for a clubhouse, official merchandise store, and other such facilities ancillary to the baseball stadium, as well as the backyard and restroom facilities? How will the lighting conditions and the impact of wind be, from the players’ perspective?
Also, will the field have natural grass or artificial turf?
We will review options during the design process going forward regarding specifics of plans with respect to locations of a clubhouse, official merchandise store, and other such facilities ancillary to the baseball stadium, and with respect to lighting conditions and other player-oriented criteria. At this point in time we plan to use artificial turf. We will review options for making improvements relative to the current baseball stadium when it comes to restrooms and other aspects involving comfort of those visiting the stadium.
In addition, we will strive to develop a baseball stadium that enables fans to enjoy a comfortable and exciting spectator experience, which will involve turning to feedback we receive in the course of designing the new baseball stadium.
Please refer to this Q&A for details on the impact of wind in the plans for the new baseball stadium.
What plans have been devised for dealing with noise with regard to the hotel adjacent to the baseball stadium?
We will review options regarding design specifics and administration regarding the hotel adjacent to the baseball stadium going forward. Meanwhile, we aim to develop a hotel that is unprecedented in terms of its integration with sports facilities and one that is available to a larger number of people. We will also proceed in reviewing specific facility options while taking into account measures to address issues of vibration and noise.
The new baseball stadium has an asymmetrical appearance relative to that of the symmetrical appearance of the current baseball stadium. As such, what is the difference in seating capacity between the first base side and the third base side? Will student baseball cheer squads be able to use stages and musical instruments and will the stadium continue to host student baseball games?
Although specifics of the new baseball stadium design are yet to be determined, we will discuss specifics of stadium operations with respective organizers going forward.
Also, even at the current baseball stadium, certain self-imposed rules for organizers in terms of operating events are established and organizers have implemented measures to reduce noise when hosting events. We will consider ways of operating the new baseball stadium to ensure as little change as possible to cheerleading activities, while also implementing noise reduction measures, taking into account the impact on the neighborhood.
Please refer to this Q&A for detail on noise levels attributable to the new baseball stadium.
Will the new baseball stadium be available for student baseball as it is now?
Also, when student and professional baseball games are played on the same day, pre-game practice for professional baseball games is currently held at indoor practice fields or rubber baseball grounds, but where will pre-game practice take place under the new plan?
We will continue to discuss specifics of stadium operations with respective organizers, as we have done thus far.Assuming that student and professional baseball games will be held on the same day, we will also discuss and look into securing venues for pre-game practice.
What sorts of conceptual approaches are you considering in regard to the new baseball stadium? Given that you apparently toured Petco Park in San Diego in the planning phase of the new baseball stadium, have there been any other stadiums that might serve as a point of reference?
In addition to Petco Park, we have toured multiple stadiums both in Japan and abroad, and are in the process of reviewing options including those involving the concept and design of the new baseball stadium.
How long will the current Jingu Stadium be available for use?
Since we are planning for a new baseball stadium which is annexed with a hotel to be completed in 2032, we will consider the continuity of sporting events in determining how long the current baseball stadium will be available for use, with the aim of using the current stadium for as long as possible.
In recent years, we have seen manifestations of climate change, such as rising temperatures and unexpectedly strong rainfall. Please explain how the new baseball stadium will be adapted for this.
Although details regarding the new stadium design and operational approach are yet to be determined, we will continue to consider specific factors such as climate change in heat mitigation measures and drainage design with a view to realizing a comfortable atmosphere for players and spectators.
Please refer to this Q&A for details on the reason why an outdoor stadium is planned.

Prince Chichibu Memorial Rugby Stadium

What changes are planned for Prince Chichibu Memorial Rugby Stadium? Rugby facilities generally do not have roofs, so why did you opt for an all-weather facility with respect to the new rugby facility, considered sacred ground for rugby? What was your thinking behind it?
The new rugby facility will be relocated and developed at the current site of Jingu Stadium and Jingu No. 2 Stadium.
It will serve as an all-weather rugby stadium with a non-retractable roof, thereby making it possible to host other sports and various events.
Moreover, the stadium will feature a sports museum and other such facilities to convey the diverse value of sports by providing opportunities for sports-related learning and enjoyment.
In the course of considering development options, the Japan Rugby Football Union submitted a written request to the Minister of Education, Culture, Sports, Science and Technology in September 2020. The request expressed the desire for development of an all-weather facility capable of being used for multiple purposes while maintaining its function as a rugby stadium, pursuant to guidelines for stadiums and arenas provided for by the Japan Sports Agency. In response to the request, the Japan Sports Agency held a meeting for stakeholders involved in promoting rugby at which a document titled “Basic Approach to Relocating and Developing the Prince Chichibu Memorial Rugby Stadium” was presented. Included in the document was the notion that an all-weather rugby facility is to be developed to serve as a comfortable facility for those who play, watch, support and gather for rugby, and that the facility is to serve as an all-weather rugby venue that can be comfortably used for other sports competitions and various events.JRFU has expressed its expectations that the transition to the all-weather facility could broaden the base of rugby, particularly through holding various tournaments and events.
Why have you decided to use artificial turf for the rugby pitch?
At Prince Chichibu Memorial Rugby Stadium, it is difficult to keep natural grass in good condition throughout the rugby season given that the facility is used for events that include international matches, League One, university championships, Kanto Intercollegiate Rugby Tournament and league matches. As such, we accordingly plan to equip the new rugby facility with a pitch that aligns with international standards, including those for safety. The pitch will meet requirements of the Japan Rugby Football Union which calls for facilities to: devise plans for a pitch adequate for international rugby competitions to be held under optimal conditions that enable athletes to compete safely, and; install artificial turf that meets turf performance standards stipulated by World Rugby, sourced from World Rugby-recommended manufacturers.
Why have you decided to reduce the number of seats at the rugby facility?
The new rugby facility will have approximately 15,000 seats, the number of which has been determined based on certain considerations. This includes facility requirements encompassing site area, buildable floor area calculated based on the floor area ratio, securing of functions and concourse space necessary for carrying out sporting events, evaluating dimensions of spectator seating, ensuring sightlines in terms of views from spectator seating. It also includes safety considerations such as those that involve ensuring smooth spectator flow. The new facility will have less spectator seating, but in practical terms there are only about 10 days per year when the number of spectators at Prince Chichibu Memorial Rugby Stadium exceeds 10,000 out of approximately 70 days allocated to rugby annually. Also, less seating will entail eliminating standing sections, maintaining proximity of the pitch to the spectator stands, and holding to the current spectator stand gradient. We also believe that the number of seats is appropriate from the perspective of ensuring a sense of unity between spectators and athletes, thereby creating an immersive spectator setting.
The National Stadium currently continues to host matches that are estimated to attract several tens of thousands of spectators.
Would you provide details about operations of the rugby facility subsequent to its completion, including number of days in use and ancillary facilities?
Given that the new rugby facility will be operated by a private finance initiative (PFI) operator to facilitate its privatization, the PFI operator will make decisions of specific details that include number of facility use days and plans for ancillary facilities.

In adjusting the number of use days, priority will be assigned to adjustments made to the number of days allocated to rugby, which is to receive at least 60 days annually per discussions with bodies such as the Japan Rugby Football Union. Moreover, with respect to ensuring that the rugby facility is used for various other purposes on other days, such that include sports, cultural events, conventions, and business matching events, the PFI operator is to work toward improving the occupancy rate of the facility in part by actively engaging in effective public relations and promotional activities, and is also to provide facilities in a manner that ensures access that is seamlessly aligned with specific purposes of use.
Would you provide details on the barrier-free elements of the new rugby facility?Are you planning any inclusive design initiatives?
The facility development policy stipulates that plans should place consideration on universal design elements (arrangement of rooms, traffic flow, signage, etc.) to ensure that the stadium is used as for international events in a manner that is fair and accessible to everyone. At present, we are holding workshops in collaboration with partners such as organizations for senior citizens and people with disabilities, and child care-focused groups. We will take their opinions into account as we advance facility development projects.
The PDF of the briefing session for residents who live in close proximity to the Jingu Gaien District Urban Redevelopment official web site lists two dates for completion of the new rugby facility, with phase one in 2028 and phase two in 2034. That said, when will the rugby facility be available for use?
The main structural elements of the new rugby facility including the roof are to be completed in phase one of the project, with the pedestrian deck on the southern side to be completed in phase two. As such, the facility will become partially available in the year 2028 upon completion of phase one, with the facility then available for purposes such as rugby competitions and other sporting events. The entire site will go into operation in the year 2034, upon completion of phase two.

* This schedule was current as of the public notice regarding project implementation approval issued on February 17, 2023.
Was your decision to do away with facilities exclusively for rugby while enlisting use of such facilities for museum and international exchange purposes made because you deem that rugby lacks inherent strength and potential?
In seeking to help establish a world-renowned sports cluster as set forth in the Tokyo Metropolitan Government’s master plan, the Japan Sport Council (JSC) will accordingly upgrade deteriorating rugby facilities and contribute to developing a lively urban location by introducing cultural exchange, shops and more to the community through the Jingu Gaien redevelopment project. Meanwhile, the concept of the project for developing and operating the new rugby facility will enlist the aim of having the facility serve as a stadium that symbolizes rugby in Japan and a stadium that conveys the diverse values of sports, thereby giving rise to plans to make a sports museum part of the rugby facility.
Would you explain in simple terms the pedestrian traffic flows in the vicinity of the new rugby facility in terms of positioning and number of entrances and exits as well as details on access from different directions?
There are to be separate pedestrian and vehicular traffic flows in the vicinity of the new rugby facility, and the site will offer smooth access in the direction of Gaienmae Station via the north-south deck and Central Plaza. Meanwhile, the Kokuritsu-Kyogijo Station side of the site will become a unified space, thereby enabling pedestrians unrestricted access.
We are currently reviewing design and other such considerations in regard to plans for the new rugby facility’s pedestrian and vehicular traffic flows. We accordingly seek to devise traffic flows that are functional and easy to understand for various people accessing the facility, including athletes, spectators, media representatives, operational personnel, and facility managers. Moreover, the plan is to take into account notions of safety assurance and universal design concepts, while also setting forth safe and mutually unobstructed traffic flows.
Given that the Prince Chichibu Memorial Rugby Stadium is owned by the Japan Sport Council (JSC), what sort of administrative procedures will be needed in relation to changes in those assets and rights associated with the relocation and rebuilding?
The Japan Sport Council (JSC), owners of the Prince Chichibu Memorial Rugby Stadium, will require approval from the Minister of Education, Culture, Sports, Science and Technology for disposal of this current asset. In addition, as part of administrative procedures for the “Jingu Gaien District Type-1 Urban Redevelopment Project,” approval from the Tokyo Metropolitan Governor is required for the rights conversion plan to be formulated by the executors of the redevelopment project. Note that these approvals will be granted on an application basis, but the timing of those applications is still under consideration.
Are there plans to hold international matches at the new rugby facility?
Also, what is the rationale for equipping the facility with seating for 15,000 spectators?
Is the seating capacity inadequate for hosting international matches?
The redevelopment plan for the new rugby facility specifies seating for approximately 15,000 spectators, which has been determined based on certain considerations set forth in the “2019 Rugby World Cup Host City Guidelines ” to satisfy standards required for hosting international rugby matches. This includes facility requirements encompassing site area, buildable floor area calculated based on the floor area ratio, securing of functions and concourse space necessary for carrying out sporting events, evaluating dimensions of spectator seating, ensuring sightlines in terms of views from spectator seating. It also includes safety considerations such as those that involve ensuring smooth spectator flow.
Furthermore, even now the National Stadium hosts matches if crowds are expected to run into the tens of thousands.
The initial conditions of the PFI tender set by the Japan Sport Council (JSC) stipulated 20,000 seats but it has been decided to only have 15,000. Please explain the reasoning behind this reduction in the number of seats. Is this reduction of 5,000 seats appropriate for a tender conducted by an independent administrative institution?
The number of seats for the new rugby facility has been 15,422 or above since the PFI project tender first opened.
We think the 20,000 seats in the initial PFI tender conditions mentioned in your question refers to “expectation of 20,000 seats” described in the “Development Policy” section of the Basic Plan for the New Prince Chichibu Memorial Rugby Stadium (Tentative Name) released in June 2021. This outlines the basic policy (vision and concept) and fundamental approach regarding the facility development plan and management and operations regarding the rebuilding of the Prince Chichibu Memorial Rugby Stadium as part of the redevelopment of the Jingu Gaien District, so it does not constitute tender conditions.
Following this, when the tender for the New Prince Chichibu Memorial Rugby Stadium (Tentative Name) Development and Operation Project opened in January 2022, the required operational standards formulated based on the above plan stipulated the number of seats as “15,422 or more” as a level that fulfilled requirements related to the development and operation of the facility, including necessary facility functions and the assurance of safety.
Our plan for the new rugby facility exceeds the requirement of 15,422 or more seats. For the reasons behind the seat number being roughly 15,000, please see the answer to this QA.
Please see the following link (Japanese only) for the basic policy and implementation policy.
https://www.jpnsport.go.jp/corp/tabid/1367/Default.aspx
It says it has been 76 years* since Prince Chichibu Memorial Rugby Stadium was completed but as the age of each stand is different, isn’t this inaccurate?
The description of 76 years* since completion is based on the history of Prince Chichibu Memorial Rugby Stadium, referring to the number of years since the Tokyo Rugby Stadium was initially completed in November 1947.
The year that renewal work on each stand was completed is as follows.
Main Stand: 1976
South Stand: 1980
Back Stand and North Stand: 1988
* This number of years described here was current as of the time the question was asked.

Plaza and open space

What changes will be made with respect to open space relative to that of the site currently?
The redevelopment plan calls for substantial expansion with respect to open space. The amount of open space, including green space, will increase nearly twofold from approximately 21% of the site now to approximately 44% of the site subsequent to development. A plaza in front of the picture gallery will be established at the current location of the reservation-based rubber baseball ground, thereby reviving the original aesthetics of the site in a contemporary format. The Central Plaza will encompass approximately 1.5 hectares and will be located between the new baseball stadium and the new rugby facility. It will contribute to better disaster resiliency by serving as a wide-area evacuation site.

Open space as a proportion of the site overall is calculated as area of the redevelopment official web site that is open to the general public, such as plazas, green space, pedestrian pathways, and other space that is integrated with such locations (such green space includes areas subject to restricted access for administrative reasons), against the area of the entire redevelopment official web site. Please note that the currently walled-off rubber baseball ground area is not included in open space because it is used on a reservation basis and as a temporary venue for events.

Under the redevelopment plan, we intend to expand space devoted to locations that enable unrestricted access, irrespective of facility use. Jingu Gaien currently has fences and barriers around each facility, which means that locations offering unrestricted passage and plaza spaces are limited. For instance, it is not possible to gain unrestricted access from the Four Rows of Ginkgo Trees to Stadium Street. Subsequent to development, pathways enabling access in all directions (north, south, east, west) will be available, allowing for greater freedom of movement. This together with new plaza space centered on Central Plaza and a plaza in front of the picture gallery will result in the creation of a place where visitors are able to relax amidst different types of greenery.
What administrative restrictions have been imposed on plazas and other such locations?
We will refrain from responding to this question at this point in time because specific administrative details pertaining to the plazas and other such locations will be subject to decisions in the future. However, there are certain general access restrictions from the perspective of facility administration not limited to this redevelopment project. For instance, restrictions may be imposed on access to some pathways at times outside of facility business hours, and restrictions may be imposed on access to plazas during periods of lawn regeneration.
Could you explain your stance at this point in time with regard to the prospect of people bringing pets to the plazas and open spaces?
Given that the redevelopment project entails the creation of more public space within Jingu Gaien accessible to many people, I think certain considerations are warranted in order to avoid potential conflicts regarding the matter of pets accompanying visitors to the location.
We will refrain from responding to this question at this point in time because specific administrative details pertaining to the plazas and other such locations will be subject to decisions in the future. As stated in the environmental impact assessment report, however, we will explore possibilities for ensuring that settings are readily accessible to visitors and conducive to activities that involve engaging with nature, taking into account the current diversity of use scenarios at the site.
What changes will be made to the plaza in front of the picture gallery?And will the large ginkgo tree be preserved?
We plan to make the plaza in front of the picture gallery freely accessible to everyone. For instance, we are likely to establish periods of lawn regeneration from an operational and administrative perspective during which there will be limited access to lawn areas.
In addition to the plaza in front of the picture gallery, we are also likely to establish the Central Plaza as an open plaza space where the general public will be able to engage in a variety of activities such as exercising, relaxing, and strolling. Specifics in that regard in terms of design and operations are subject to review going forward.
Although not a plaza, the newly planned mixed-use building B along Stadium Street is subject to plans for development of an indoor ballgame facility and rooftop plaza, thereby helping to promote interaction in various sports such as futsal amid extensive use by athletes and the general public.

Moreover, for results of our review conducted with respect to options for preserving and transplanting the trees located in front of the picture gallery in alignment with the approach applied to other locations (number of trees to be preserved and transplanted, etc.), please access this website page.
We plan to preserve the large ginkgo tree located in the plaza in front of the picture gallery.
Would you provide information about the new tennis courts?
Also, what aspects of the current tennis court operations will be carried forward to the new tennis courts?
The new tennis courts will be situated on both sides of the plaza in front of the picture gallery. For non-member use, we plan to make tennis school available to everyone and rental courts available to everyone through reservation. Landscaping will be added on the plaza side of the tennis courts, with further consideration given to aesthetics as we proceed with design considerations going forward.

Moreover, we are reviewing options for enlisting management operations of the current tennis court facility as the foundation for the new tennis courts.
What are your options with respect to Central Plaza?Also, how often do you expect events to be held in the Central Plaza, and what is your thinking regarding noise abatement measures during such events?
Plans for the new Central Plaza entail its use as a plaza space where everyone will be able to engage in a variety of activities such as exercising, relaxing, and strolling. We will review options going forward with respect to specific details that include rentals for the general public, periods of lawn regeneration, and nighttime operations.Events currently being considered for the Central Plaza include outdoor yoga classes, sports events led by top athletes and others. Along with the specific type and frequency of events, we will also consider concrete noise abatement measures while considering area residents and others in the vicinity, as we have done with the new baseball stadium.
What is your overall conception for the cultural exchange facility?
Regarding the cultural exchange facility, we will post an overall conception as we continue with more detailed planning. As of the present, we’ve posted an overview including a partial conception at the following URL on the official web site.
https://www.jingugaienmachidukuri.jp/en/vision/
The cultural exchange facility, which will be open to use by all, will provide rest, exchange, and sports support. As a center for various activities, the plan is to utilize it as facility for cultivation that connects people together.

Mixed-use building A, mixed-use building B, and office building

【NEW】 Could you please discuss the uses of the facilities in the high-rise buildings and the proportion of each use?
The uses of facilities in mixed-use building A, mixed-use building B, and the office building are described below.

Mixed-use building A: Office, shops, lobby, multi-purpose room, parking space, etc.
Mixed-use building B: Serviced apartments, indoor ballgame facility, parking space, etc.
Office building: Office, shops, lobby, parking space, etc.

Specific details on the proportion and uses are currently under consideration.
【NEW】 What kind of users do you envision for the serviced apartments planned for mixed-use building B?
We expect the serviced apartments to accommodate a wide range of individuals for medium- and long-term stays. They will include sports athletes, related parties and other users visiting from Japan and abroad during events at sports facilities, as well as users of nearby facilities.
【NEW】 What are the economic benefits of this project in monetary terms?
We don’t have specific monetary figures to present regarding the project’s economic benefits at this time. However, we will create a neighborhood that attracts many people from around the world by taking steps such as enhancing the sports viewing experience, expanding green and open spaces, and improving pedestrian walkability and access. For the total cost of the project, please refer to this Q&A.
Why will the mixed-use building A and office building be built as high-rise buildings? My understanding is that the population is declining and vacancy rates for office buildings are rising, so why are you constructing high-rise buildings?
One objective set forth in the urban redevelopment guidelines established by the Tokyo Metropolitan Government is that of fostering vitality through intensive use of land situated along Aoyama Street and elsewhere.

This urban redevelopment project enlists plans to fully leverage distinctive characteristics of the area around the project site. This will entail developing large plazas, improving disaster resiliency by having the location serve as a wide-area evacuation site, and upgrading sports facilities that have been subject to deterioration. We will also seek to limit capacities particularly with respect to the vicinity of the Four Rows of Ginkgo Trees, the new baseball stadium and the new rugby facility from the perspective of preserving scenic views and landscapes overlooking the picture gallery, and from the perspective of creating spacious visual aesthetics in the vicinity of Central Plaza. We will plan projects that private sector companies can invest in by seeking to promote urban redevelopment in an integrated manner through the intensive use of land for offices, commercial space, hotels and other such establishments along Aoyama Street and Stadium Street.

For example, Mitsui Fudosan is establishing mixed-use building A, through which it will aim to generate revenue by renting a portion of land owned by Meiji Jingu and then advancing mixed-use development that includes high-rise buildings for offices, hotels, and other purposes. The capital for this endeavor will be paid to Meiji Jingu as rent which will supplement the revenue generated by Jingu Gaien.
While we accept that there may be concerns abouts high-rise buildings in relation to population decline and rising vacancy rates, we believe this development will be highly competitive as Mitsui Fudosan will leverage its expertise to create appealing facilities, including mixed-use building A, a high-rise building for offices and other purposes.

Itochu Corporation is planning to construct an office building that is larger than its current office building, but it will fund the redevelopment project to cover the added value it will gain.

This rent from Mitsui Fudosan and funding from Itochu Corporation and other developers will not only fund the rebuilding and renewal of Jingu Gaien District facilities, but also produce revenues beyond this, creating a cycle that will enable us to continue protecting Jingu Gaien’s greenery into the future.

* Under Japan’s urban planning guidelines, the notion of “intensive use of land” is defined as making efficient use of land. This involves ensuring that roads and other public facilities are maintained at or above a certain level and otherwise creating favorable urban environments by gaining access to available vacant land and ensuring a minimum prescribed site area.
Would you address concerns regarding the compatibility of the high-rise buildings and high school in the vicinity?
The building core of mixed-use building A, which is to consist of offices and other facilities, will be located on the west side of the building while the windows will primarily be situated on the east side of the building. Meanwhile, windows of mixed-use building B, which is to consist of serviced apartments and indoor sports facilities, will be located on both the east and west sides of the building. We will review options going forward taking into account issues of compatibility with surrounding facilities.
How will this affect the population of office workers?
I’m concerned about congestion at the station due to increase in commuters.
We anticipate an overall increase of approximately 13,000 people in the population of workers at each facility of the redevelopment plan. In terms of addressing the notion of station user congestion attributable to the increase in the working population, we are engaging in discussions with Tokyo Metro Co., Ltd., particularly with respect to having more ticket gates installed and wider passageways at Gaienmae Station. The redevelopment project enlists plans for connecting the basement of the office building with the underground passageway of Gaienmae Station on the Ginza Subway Line, thereby enabling access to ground level in the proximity of Aoyama 2-chome intersection via the underground passageway of the office building. Meanwhile, Itochu Corporation has adopted morning shift scheduling (recommended morning shift working hours: 5:00-8:00) as part of its workstyle reforms for achieving greater labor productivity. Currently, over half of Itochu Corporation’s employees start work before 8:00 in the morning.
Why is Itochu Corporation building a new head office building, with the current one being over 40 years old?
Itochu Corporation has been considering the possibility of rebuilding its head office in the future given that its current one is over 40 years old. Participating in the redevelopment project will enable Itochu Corporation to rebuild its Tokyo head office building. Moreover, this will make it possible for Itochu Corporation to plan a building that is integrated with the local community, particularly in terms of enhancing disaster resiliency by accepting people who are unable to return home when a disaster strikes, expanding the pedestrian network and strengthening barrier-free infrastructure in part by creating underground passageways and developing plazas.
I have a question regarding mixed-use building A. Is it not possible to fund the entire redevelopment project using revenue from only the office portion of mixed-use building A? Or is the project scheme designed to generate revenue using both the sports facilities and other facilities?
Also, what kind of companies do you expect to occupy offices in mixed-use building A?
The project’s profit objectives are based on the integrated use of the entire urban redevelopment project area. (For more details, please refer to the Q&A regarding “Reasons for constructing high-rise buildings”)

Mitsui Fudosan, the project developer for mixed-use building A, issued a press release on July 5, 2024 reiterating the purpose of the redevelopment and details of the project scheme. Please refer to the release (Japanese only) for further details:
https://www.mitsuifudosan.co.jp/corporate/news/2024/0705/

In terms of companies expected to occupy mixed-use building A, no specific policies on attracting tenants have been decided at this time. We hope that many companies will become tenants and we plan to release more information about mixed-use building A as the design process moves forward.

Framework of the redevelopment plan

Would you go over development efforts in terms of what has happened thus far and the schedule going forward?
The redevelopment project is being promoted by four entities, namely Mitsui Fudosan Co., Ltd., Meiji Jingu, Japan Sport Council (JSC), and Itochu Corporation. In March 2023, the project began with the demolition of Jingu No. 2 Stadium, upon receipt from the Tokyo Metropolitan Government of public notice regarding approval of the “Jingu Gaien District Type-1 Urban Redevelopment Project” in February 2023. We will provide notification regarding construction schedules for each facility and other specific details as soon as they are finalized.
Please access this website page for details regarding the steps involved in the rebuilding to be carried out in phases.
How will the administrative procedures progress as the Jingu Gaien District Urban Redevelopment Project after November 2024?
Going forward, we will carry out various procedures concerning the Jingu Gaien District Urban Redevelopment Project in the appropriate manner at the appropriate time. This will include applying for approval of the rights conversion plan based on the Urban Renewal Act and submitting building permit applications based on the Building Standards Act.
What is your approach to handling procedures for having restrictions eased?
Regulations have been eased with respect to specifications that include floor area ratio, height, building area, site area, and new restrictions have been imposed, in line with changes to the District Plan in March 2022.
Refer to the following website (Japanese only) for further details.
https://www.toshiseibi.metro.tokyo.lg.jp/bosai/toshi_saisei/data/saisei07_06.pdf
What are the height restrictions for the buildings?
What ordinances or regulations are such restrictions based on and at what height are the restrictions set in meters? Please provide specific information including Scenic District relevance.
On March 10, 2022, the Jingu Gaien District formulated the District Plan that Designates Redevelopment Promotion Districts, which stipulates the maximum height of buildings and other structures as follows.
• A-7 district (rugby facility): 55 m
• A-8-a district (mixed-use building B): 80 m
• A-8-c district (mixed-use building C): 185 m
• A-9 district (office building): 190 m
• A-10 district (new baseball stadium / cultural exchange facility): 60 m
[Relevance to Scenic District]
With some of these areas having been designated as Scenic Districts, under the Tokyo Scenic District Ordinance it is deemed that “certain conditions imposed on the construction of buildings do not apply if it has been duly recognized that effective measures are being implemented to maintain scenic beauty with respect to the site of the building, and furthermore if it has been recognized that the building’s location, size, format, design, building coverage ratio, and floor area ratio are not significantly discordant with the size and format of the building’s site and also not discordant with the building’s site and area of land in the vicinity” (excerpt from Article 5, Paragraph 5 of the Tokyo Scenic District Ordinance).
Moreover, the Standards for Examination of Permits Pursuant to Scenic District Ordinance specify Scenic District area classifications and stipulate requirements for selecting classifications of each area. Accordingly under such standards, areas slated for construction of sports facilities and mixed-use buildings in such districts (Shinjuku City: S-(c) Area; Minato City: S Area) are “areas warranting special designation as districts subject to application of public urban development methods; and such areas may be further classified to ensure consistency with public urban development methods, etc.” In addition, according to a separate table of the Standards for Examination of Permits Pursuant to Scenic District Ordinance, buildings may be subject to less stringent height requirements within the scope of the Operational Standards for District Plan that Designates Redevelopment Promotion Districts. The maximum heights of buildings and other such structures have been set as listed above under the District Plan based on such regulations.
Meanwhile, the office building is not subject to application of the Scenic District Ordinance because it is located outside the Scenic District.
Under the redevelopment project, are Mitsui Fudosan, Itochu, Meiji Jingu and Tokyo Metropolitan Government designated as individual business owners?
Also, why was the individual execution approach chosen?
There are five types of entities for execution of urban redevelopment projects pursuant to the Urban Renewal Act under the categories: redevelopment association execution, individual execution, redevelopment company execution, local government execution, and Urban Renaissance Agency, local housing corporation execution. The individual execution approach applies to the redevelopment project. The executors of the project (Mitsui Fudosan Co., Ltd., Meiji Jingu, Itochu Corporation, and Urban Renaissance Agency) are classified as individual executors and not as independent business owners. The Tokyo Metropolitan Government serves as an approval authority and not as a business operator.
Given that there are fewer than five landowners, the redevelopment does not meet requirements for establishment of an urban redevelopment association. It accordingly enlists the approach of individual execution by unanimous consent whereby the project proceeds per consent of all rights holders.
Why is the redevelopment project necessary?
The purpose of the redevelopment project is that of protecting and maintaining Meiji Jingu Naien (inner garden) and Gaien (outer garden) well into the future. The shrine and forest of Meiji Jingu Naien, as well as the green space of Meiji Jingu Gaien, have been maintained with support from income generated by various facilities of Meiji Jingu Gaien. Among such facilities, Jingu Stadium has played a particularly crucial role in this regard. As such, renovating Jingu Stadium through this redevelopment will make it possible to protect and maintain Meiji Jingu Naien and Gaien for the next century.
The Jingu Gaien District faces various challenges. For instance, major renovations are needed given that more than a half century has passed since sports facilities were built in the district. Moreover, open spaces for relaxation are lacking, pedestrian flow between facilities is poor, and pedestrian pathways are not adequately barrier-free.
As such, the objective of the redevelopment project is to address such issues while at the same time establishing secure, safe and attractive settings for visitors by creating a world-class sports cluster offering coordinated use of various facilities.
This urban redevelopment project enlists plans to fully leverage distinctive characteristics of the area around the official web site. This will entail developing large plazas, improving disaster resiliency by having the location serve as a wide-area evacuation site, and upgrading sports facilities that have been subject to deterioration. We will also seek to limit capacities particularly with respect to the vicinity of the Four Rows of Ginkgo Trees, the new baseball stadium and the new rugby facility from the perspective of preserving scenic views and landscapes overlooking the picture gallery, and from the perspective of creating spacious visual aesthetics in the vicinity of Central Plaza. We will furthermore seek to promote urban redevelopment in an integrated manner by seeking to achieve intensive use of land for offices, commercial space, hotels and other such establishments along Aoyama Street and Stadium Street.
Please access this website page for details regarding current issues and future plans.
Who will be the land and building owners?
What will be the operational approach for the Central Plaza?
At this point in time, the assumed owners of the land and buildings for each of the facilities is as follows.
• Office building: (Land) Itochu Corporation; (Building) Itochu Corporation
• Mixed-use building A: (Land) Meiji Jingu; (Building) Mitsui Fudosan
• Mixed-use building B: (Land) Meiji Jingu; (Building) Mitsui Fudosan
• New rugby facility: (Land and building) JSC
• New baseball stadium complex: (Land) Meiji Jingu; (Building, baseball stadium) Meiji Jingu; (Land) Meiji Jingu; (Building, hotel) Mitsui Fudosan
• Cultural exchange facility: (Building) Mitsui Fudosan; (Land) Meiji Jingu
• Tennis courts: (Building and land) Meiji Jingu

Details regarding the operational approach subsequent to project completion have yet to be determined. It is envisaged that the Central Plaza will serve as an open plaza space where the general public will be able to engage in a variety of activities such as exercising, relaxing, and strolling. It is designed with water supply, water drainage, and electrical facilities to enable use for sports and other events.
Would you explain your approach to rights conversion with respect to each of the facilities?
Each rights holder will acquire assets equivalent to their pre-existing assets through rights conversion carried out pursuant to the Urban Renewal Act.
Will the method for rights conversion in this redevelopment be based on Article 111 of the Urban Renewal Act (non-setting of superficies rights)?
The preparation of a rights conversion plan and application for approval will be carried out going forward so details regarding rights conversions have yet to be determined.
Will Meiji Jingu assume the cost burden and tax obligations associated with this project?
Given that the nearby residents are deemed interested persons pursuant to the Religious Corporations Act, can you disclose financial details such maintenance and management expenses?
As is the case with the other project developers, Meiji Jingu will also assume cost burdens based on the rights conversion plan of this project. In regard to business involving operations encompassing maintenance and management subsequent to project completion, Meiji Jingu is to assume tax obligations in accordance with Article 4, Paragraph 1 of the Corporation Tax Act.
Pursuant to Article 25, Paragraph 3 of the Religious Corporations Act, we will respect the freedom and autonomy of religious corporations while simultaneously adhering to the understanding that exceptional access to information may be permitted only upon having deemed that a believer or other interested person has legitimate interests and not unjustifiable grounds for such access. We deem that nearby residents do not qualify as interested persons and have accordingly determined that they do not meet other requirements for information access. This interpretation aligns with the legislative intent of the Religious Corporations Act and has been applied in subsequent administrative interpretations.
I have heard the plan is to maintain Jingu Naien (inner garden), but what will the annual costs be to maintain it?
We will refrain from giving specific figures, but Gaien’s revenue is essential to maintain all of Meiji Jingu, including Naien.
What is the total cost of the redevelopment, the cost of each building, and projected profits after completion?
The total cost of the redevelopment will be ¥349.0 billion.
Regarding the new rugby facility, the Japan Sport Council has announced that the facility development cost will be roughly ¥53.8 billion and the consideration for stadium operating rights (30 years) will be approximately ¥45.3 billion (both including tax, as of November 2022). However, we will refrain from providing information about the cost of other buildings and projected profits.
How did the Scenic District district classification change come about?
Shinjuku City apparently made the Scenic District district classification change in February 2020.
What are your plans for redevelopment of the plaza in front of the picture gallery?
Are these the type of development activities that need a permit?
The Park & Urban Redevelopment Plan will be applied to the project for renewal of the site in front of the picture gallery upon having conducted comprehensive assessment under that plan. Please refer to the following website link for an overview of the Park & Urban Redevelopment Plan.
Assessment results of Jingu Gaien District park and urban redevelopment plan (Japanese only): https://www.toshiseibi.metro.tokyo.lg.jp/bosai/toshi_saisei/saisei07_06.htm
Moreover, the project for renewal of the site in front of the picture gallery does not require a development permit based on ordinances and enforcement regulations concerning protection and recovery of nature in Tokyo. Whereas the plan does not contain details that would require a permit for development activities based on the City Planning Act at this point in time, the project will proceed with appropriate procedures in accordance with relevant laws and regulations as the design process deepens, including the changes made to certain aspects of the plan released in September 2024.
In January 1952, Japan’s Ministry of Education entrusted operations of the Gaien (outer garden) facilities to Meiji Jingu under the following conditions: citizens are to have fair access; fees for facility use and admission are to be extremely low in keeping with the principles of amateur sports; the prospect of covering future facility repairs and maintenance is to be sustained; management is to be carried out in a manner that adheres to democratic principles.
Will the redevelopment project align with requirements set by the Ministry of Education?
Athletic facilities owned by Meiji Jingu consisted of a baseball field, athletic stadium, and swimming facility after General Headquarters (GHQ) restored possession of the facilities based on discussions held with the Ministry of Education (since renamed as Ministry of Education, Culture, Sports, Science and Technology, or MEXT). After that, the athletic stadium was transferred to the government and subsequently rebuilt on two occasions to ultimately become the current National Stadium. Meanwhile, the swimming facility completed its mission in serving as an athletic facility. The only remaining facility is the baseball stadium, which continues to operate under the requirements just pointed out.

As such, plans call for updating the facility as part of the project for the sake of ensuring continued operation of Jingu Stadium well into the future. In addition, the appearance and structure of Meiji Jingu will undergo change, passing on the legacy of Jingu Stadium into the future will serve an indispensable role in protecting and maintaining Meiji Jingu.
Will the project receive any subsidies or grants from the national government or Tokyo Metropolitan Government?
There are no plans to seek subsidies or grants for the redevelopment project from the national government or Tokyo Metropolitan Government. The redevelopment project is being promoted by four entities, namely Mitsui Fudosan Co., Ltd., Meiji Jingu, Japan Sport Council (JSC), and Itochu Corporation.
Would you go over details with respect to a timeline and background information on the formulation of the master plan by the Tokyo Metropolitan Government, Minato City, and Shinjuku City?
Given that the master plan was formulated by the respective local governments, we will refrain from providing a reply as the project developers.
What is the Park & Urban Redevelopment Plan?
How do long unused areas fit into the redevelopment project?
Established by the Tokyo Metropolitan Government in December 2013, the Park & Urban Redevelopment Plan targets unused sections of urban development park with the aims of swiftly establishing park features and fostering vitality by striking a balance between urban development with parks and green space in a manner that taps opportunities for private sector urban development. The Park & Urban Redevelopment Plan seeks to secure unused areas of a certain size or larger for use as green space, etc., thereby targeting urban planning parks and green space with unused areas with respect to which more than around 50 years have elapsed since the initial urban planning decision was made. It also seeks to create green space, etc. within urban developments, thereby transitioning to urban planning parks and green space provided that a project meets certain requirements.
The pre-existing unused area of the redevelopment project is centered around the current site of Prince Chichibu Memorial Rugby Stadium. The redevelopment project is one that entails creating park-like space that anyone is able to enter at any time, and also entails developing shops, cultural exchange facilities, and other such locations available for use even when the rugby facility is not in use.
【NEW】 Have the members of the Environmental Impact Assessment Council visited the transplant sites in the project area?
The developers do not have information on such activities.
This project is being conducted under the Park & Urban Redevelopment Plan. What is the opinion of the developers’ regarding the project’s conformity with the Plan’s objectives?
The Park & Urban Redevelopment Plan aims to swiftly establish park features and achieve beneficial urban development in city-planned parks, including those that have been unused for a long time, by striking a balance between urban development and maintenance of parks and green space in a manner that taps opportunities for private sector urban development.
The Jingu Gaien District has been designated as a city-planned park, but part of the district (an area covering approximately 4.7 hectares, including the Prince Chichibu Memorial Rugby Stadium) has been unused for a long time, and the entire district has issues such as aging sports facilities and a lack of open plaza spaces and pedestrian accessibility. Therefore, we believe that the swift establishment of park features is required and in line with the Park & Urban Redevelopment Plan’s objectives.
In addition, the district is designated as a wide-area evacuation site and is considered important for disaster prevention, so we will work to strengthen and improve the district’s disaster preparedness.

For more information on the Park & Urban Redevelopment Plan, please refer to the following link (Japanese only) from the Bureau of Urban Development, Tokyo Metropolitan Government.
https://www.toshiseibi.metro.tokyo.lg.jp/kiban/kouen_2.htm
I have heard that Type-1 Urban Redevelopment Project refers to a “development project for districts with dense concentrations of wooden structures and unfavorable land use conditions. As such, which areas of Jingu Gaien are deemed areas with a high density of wooden structures?
According to information released by Japan’s Ministry of Land, Infrastructure, Transport, and Tourism (MLIT), a Type-1 Urban Redevelopment Project is a project that involves development of structures, construction sites and public facilities in seeking to achieve reasonable and sound intensive use of urban land and renewal of urban functions. As such, a Type-1 Urban Redevelopment Project is not restricted solely to areas with high concentrations of wooden structures.
(https://www.mlit.go.jp/toshi/city/sigaiti/toshi_urbanmainte_tk_000069.html) (Japanese only)
Will reasons for selecting contractors and results of bidding on construction of new buildings be disclosed?
We do not plan to publicly disclose selection criteria for contracting each facility with respect to private-sector projects. However, information on bidding for Prince Chichibu Memorial Rugby Stadium is available on the official website of Japan Sport Council (JSC) (Japanese only).
https://www.jpnsport.go.jp/corp/chotatu/tabid/1554/Default.aspx
What are the heights of each of the facilities?
At this point in time, the assumed heights of each of the facilities are as follows.
• Office building: Approx. 190 m
• Mixed-use building A: Approx. 185 m
• Mixed-use building B: Approx 80 m
• New rugby facility: Approx. 55 m*
• New baseball stadium: Approx. 60 m
• Cultural exchange facility: Approx. 6 m
Also refer to the briefing materials available on this website for overviews of each facility.
English translation of the material of briefing sessions:
https://www.jingugaienmachidukuri.jp/pdf/explanation_en.pdf
* In September 2024, we announced that the height of the new rugby facility has been changed to approximately 48 meters. We will carry out the various procedures necessary in this regard going forward.
After each of the facilities has been rebuilt in the future, it will apparently be more convenient for people coming by car and stakeholders, but what is the current number of parking spaces at each facility? And what is the planned number of parking spaces when all the facilities are complete?
The current number of parking spaces at each facility is as follows: Prince Chichibu Memorial Rugby Stadium has 68 spaces, Jingu Stadium approx. 130 spaces and the Itochu Corporation Tokyo head office building 238 spaces.
The number of parking spaces for each facility after they have been rebuilt is planned* as follows: The new rugby facility will have approx. 98 spaces, the new baseball stadium approx. 320 spaces (including the hotel), the office building (the new Itochu Corporation Tokyo head office) approx. 320 spaces, mixed-use building A approx. 205 spaces and mixed-used building B approx. 80 spaces.
* Plan as of the time of public notice regarding project implementation approval in February 2023

Moreover, going forward the managers of each facility will consider operational methods for parking spaces at each facility.
I look forward to seeing results of the redevelopment project. Is Mitsui Fudosan in charge of the overall project?
Thank you. This redevelopment project is being carried out in a manner that takes into account feedback from various experts, including each project developer, designers, tree doctors, and consultants. Going forward, we will incorporate the knowledge of experts as necessary with the aim of further improving the project.
The environmental impact assessment report refers to “the legacy brought about by the Tokyo 2020 Olympic and Paralympic Games,” under section “6.1 Purpose of the project” on page 15 of the report. What exactly is meant by “legacy?”
Vision 19 of “Future Tokyo: Tokyo’s Long-Term Strategy” formulated by the Tokyo Metropolitan Government in March 2021 sets forth a vision for Tokyo such that, “given the city’s legacy shaped by athletes overcoming challenges of the COVID-19 pandemic in their resilient performances during the Tokyo 2020 Games, the entire urban landscape has been transformed into a sports field where everyone is able to enjoy sports.” Based on that vision, this redevelopment project seeks to establish a hub where functions such as those involving business and commerce combine with interactive functions centered on sports culture. As such, we seek to create a setting that enables a “do, watch, and support” approach to sports and parasports.
For instance, the redevelopment project seeks to enable the site to persist by carrying out in phases reconstruction of deteriorating facilities such as Jingu Stadium and the rugby facility, while also seeking to establish lively spaces that people are able to visit even when no sports competitions or other events have been scheduled. To such ends, the project seeks to improve sports functions in part by introducing liveliness, relaxation and interaction functions, and by providing increased opportunities for activities. From the perspective of the legacy associated with the Olympic and Paralympic Games, we intend to engage in efforts that include making sports facilities barrier-free and expanding wheelchair spectator seating based on the latest barrier-free and universal design knowledge gained with respect to Olympic and Paralympic-related facilities.
For further details, refer to section “6.1 Purpose of the project” on page 15 of the environmental impact assessment report, below.
Environmental impact assessment report (Japanese only): https://assess-toshokohyo.metro.tokyo.lg.jp/uploads/web_public/357_jinngugaien/06/06202235702.pdf
For the urban redevelopment project, what considerations will you place on differences in land valuations when performing rights conversion with respect to land of rights holder?
Going forward, we will prepare a rights conversion plan and apply for approval. Meanwhile, we plan to establish respective values of pre-existing residential land at their reasonable values pursuant to Article 80, Paragraph 1 of the Urban Renewal Act. Specifically, the values will be determined based on real estate appraisal, similar to other urban redevelopment projects.
Although ICOMOS has raised criticism in pointing out that, “constructing high-rise buildings in spaces previously used as parks is a concern,” in looking at the development plan it appears that the high-rise buildings will be constructed on the former sites of Jingu Stadium and the rugby facility, as well as reconstruction of existing buildings. As such, am I correct in my understanding that the criticism of ICOMOS regarding construction of high-rise buildings in a park is mistaken?
The office building enlists a reconstruction plan for an existing building situated in a location outside of the urban planning park area not classified as a Scenic District. The planned construction sites for mixed-use building A and mixed-use building B are outside the urban planning park area, with the current usage comprising part of the rugby facility site and part of the Jingu Stadium site.
Meanwhile, changes to the urban planning park area gained urban planning approval by the City Planning Council on March 10, 2022.
Given the size of the project area and the fact that it includes a Scenic District, I believe that this project is required to submit a report of its greening plan and receive development permission under the “ordinances and enforcement regulations concerning protection and recovery of nature in Tokyo.” Is that correct?
Also, please tell us what kind of laws and regulations require approval and authorization for the development activities described above.
This project is required to submit a report of its greening plan and is subject to development regulations under the ordinances and enforcement regulations concerning protection and recovery of nature in Tokyo.
It is also necessary to comply with various related laws and regulations such as the City Planning Act, Urban Renewal Act, Building Standards Act, Scenic District Ordinance, Road Traffic Act, and the Act on Waste Management and Public Cleansing.
We will proceed with the appropriate procedures while confirming the relevant laws and regulations as the design of each facility progresses.
When are you planning the procedures for closure of the Minato City road from the Four Rows of Gingko Trees to the east gate of the Prince Chichibu Memorial Rugby Stadium?
We will move forward taking appropriate steps while in discussion with relevant government organizations before starting redevelopment of the applicable area (planned for 2028).
On an NHK report on April 5, Mitsui Fudosan’s Director Suzuki responded as follows about the purpose and significance of the redevelopment project, but what is the purpose and significance from the point of view Itochu Corporation, Meiji Jingu and the Japan Sport Council?

Jingu Stadium was built 98 years ago and Prince Chichibu Memorial Rugby Stadium was built 77 years ago, they are quite problematic from aging and barrier-free perspectives. The facilities need to be made new to make money to firmly protect the Naien greenery.
The response in the NHK report that you allude to, was expressed to convey in an easy-to-understand manner from the point of view of the representative executor the significance and purpose of the project as Meiji Jingu occupies the largest amount of area in the development zone for this project, and it was expressed within the limitations of a television interview. As for redevelopment overall, as stated on the official web site, the significance and purpose of the project for developers Mitsui Fudosan, Meiji Jingu, the Japan Sport Council and Itochu Corporation are as follows.
- Based on the issue of a lack of open spaces for relaxation that are accessible to all, while preserving historical scenery such as the Four Rows of Ginkgo Trees, we will increase greenery and open spaces.
- Based on the issue of aging large-scale sports facilities, we will create a world-class sports cluster, which will be achieved by renovating, in sequence, the aging sports facilities, and by implementing this renewal in due consideration of continued hosting of sports events.
- Based on the issue of poor pedestrian access in the area, we will promote the development of a new park complex that represents Tokyo, with barrier-free access to each facility and where various visitors can move around safely and have fun during events.
- Based on the issue of the necessity of maintaining and improving function as a wide-area evacuation site, we will improve disaster preparedness as a wide-area evacuation site by linking urban functions with open spaces such as plazas and large-scale sports facilities.
I have heard that Mitsui Fudosan will rent land from Meiji Jingu for the site for mixed-use building A. Please explain the contract form and term.
For mixed-use building A, Mitsui Fudosan plans to rent a portion of land owned by Meiji Jingu to carry out mixed-use development, including high-rise buildings for offices and other purposes, and it will pay rent to Meiji Jingu. This rent will contribute to Jingu Gaien’s revenue, creating a cycle that will enable us to continue protecting Jingu Gaien’s greenery into the future.
Please understand that we are unable to provide details about the content of individual contracts.

Greenery

Why will the trees be removed?
How many will be removed?
Existing trees will undergo detailed study regarding their conditions, receiving the suggestions of experts including tree doctors. Each and every tree will be handled with care, preserving them to the best possible extent or transplanting them through various ideas implemented in the plan, so as to protect the rich natural environment of Jingu Gaien. In addition, new trees will be planted to raise the ratio of greenery upon completion of the project from about 25% to around 30%, while the number of trees 3.0 meters or taller* in the district is expected to be increased from 1,904 to 2,304.
Trees that will hinder the development work of each facility will be transplanted as a general rule. Meanwhile, those trees which tree doctors find difficult to transplant in view of the tree’s state of growth will be removed. For the entire project area, 619 tall trees are expected to be removed. Additionally, trees that require removal will be put to optimal utilization with attention to the environment.
* Please see the release of September 2024 for specific details.
“Further Measures to Preserve Trees and New Measures to Create Greenery in the Jingu Gaien District Urban Redevelopment Project”
URL:https://www.jingugaienmachidukuri.jp/pdf/en-jingugaienmachidukuri_news_2024090901.pdf
Whereas the ratio and amount of greenery are slated to increase, how will that translate to change in greenery volume?
Also, how many years will it take for the site to return to its original state?
The existing trees will be handled with care under the redevelopment project. The Four Rows of Ginkgo Trees will be preserved through our utmost efforts to preserve or transplant the existing trees enlisting various ideas. Meanwhile, we will create new greenery by increasing the proportion of greenery from approximately 25% to approximately 30%, thereby increasing the number of trees from 1,904 trees to 2,304 trees. Information on this is available via the project website and elsewhere.
Meanwhile, the volume of greenery has been calculated within the scope of the environmental impact assessment report, excluding the picture gallery front lawn area, and will be decreased by approximately 14,818㎥ cubic meters to 331,466㎥ subsequent to project completion from 346,284㎥ currently. It has been calculated based on the green space area multiplied by plant community height (average tree height for a respective area with a large amount of greenery).
The decrease in greenery volume is largely attributable to a lower height of newly planted trees. The greenery volume is bound to increase to a certain extent as the height of the trees increases with their growth. Moreover, we will continue to implement appropriate management and cultivation practices with respect to both preserved and transplanted existing trees as well as newly created green spaces, thereby accommodating a diverse range of tree species as is the current practice. This will result in more greenery volume and formation of abundant woodlands over the next century. However, we have not conducted specific estimates of the recovery period.

Please refer to the relevant pages of the environmental impact assessment report submitted in January 2023 (pages 359 and 360 via the link below) for specific details on greenery volume.
Biology/Ecosystem (Japanese only): https://assess-toshokohyo.metro.tokyo.lg.jp/uploads/web_public/357_jinngugaien/06/06202235712.pdf

Meanwhile, greenery volume figures revised in response to suggestions and advice from the City Planning Council regarding the green landscaping plan have been made public. The ultimate greenery volume figure is 331,466㎥ (approx. 330,000㎥) relative to the current 346,284㎥.
The plan states that native species will be used for new tree planting, but will only domestically cultivated trees be used? I am concerned about possible damage caused by the transfer of foreign pests and diseases if foreign-cultivated trees are used for new tree planting.
As stated in the environmental impact assessment report, we plan to select tree species for planting by referencing the “Guidelines for Selection of Native Species at the Time of Planting - Aiming at Planting in Consideration of Biodiversity” (Tokyo Metropolitan Government, May 2014) and the “Biodiversity Greening Guide” (Minato Ward, January 2016).
While tree planting will not be limited to native species, we plan to carefully study the selection of tree species with a focus on native species. We are not considering planting imported foreign-cultivated trees at this time, but if this is an option in future, we will ensure it is carried out legally and appropriately based on the advice of tree doctors and other experts to prevent the concerns you mentioned.

For more information about the species of trees currently being considered for planting, please refer to the following document on the project website.
https://www.jingugaienmachidukuri.jp/pdf/en-green01.pdf
When planting new trees, will you plant seedlings or transplant mature trees?
The plan is to plant mature trees.
【NEW】 How many trees (tall trees) will there be per hectare across the entire project area?
The total site area for the project is approximately 28.4 hectares. As of 2019, there were 1,904 trees 3.0 meters or taller in the district. After development, the number of trees is expected to increase to 2,304 through new tree plantings.

* The site area subject to the environmental impact assessment covers approximately 17.5 hectares, and, within this area, there were 1,381 trees 3.0 meters or taller as of 2019.
What approach do you use in calculating green area?
We estimate that green area will increase to approximately 30% subsequent to development, from approximately 25% prior to development. We used aerial photographs to determine the existing green area. We determined future green area based on diagrams of the current green landscaping plan, calculated by dividing horizontal projection area of green space by total area of residential land located within the area of the district development plan. This encompasses green elements such as shrubs and other ground cover, rooftop greenery, and grass.
Whereas the project will embrace new concepts of greenery enlisting various green elements such as grass, shrubs, and flowering plants in addition to trees that will grow larger, we will also consider detailed plans going forward in seeking to maintain green spaces that visitors to the site will appreciate.
Would you provide details on ownership and management of the Four Rows of Ginkgo Trees area?Please explain the ownership and management situation of the 18 ginkgo trees on the section of Minato City road leading up to Prince Chichibu Memorial Rugby Stadium.
Regarding ownership and management classifications of the Four Rows of Ginkgo Trees, the inner two rows of trees are to be owned and managed by the Tokyo Metropolitan Government and the outer two rows of trees are to be owned and managed by Meiji Jingu.
The 18 ginkgo trees on the section of Minato City road leading up to Prince Chichibu Memorial Rugby Stadium are owned and managed by Minato City.
Regularly scheduled pruning work is to be conducted jointly and each party is to assume responsibility for proper daily management.
Would you provide details on the Four Rows of Ginkgo Trees in terms of current status of tree growth and implementation of remedial measures?
You say that the Tokyo Metropolitan Government owns and manages the two inner rows of gingko trees. What remedial measures is it taking?
In the course of engaging in daily management of Meiji Jingu since November 2019, we find that some trees among the Four Rows of Ginkgo Trees have been shedding their leaves earlier than other trees. For this reason, caretakers have implemented remedial measures (soil improvement and fertilization) and watering with respect to some of the ginkgo trees based on consultations with tree doctors and other experts.

We confirmed that new buds sprouted in early spring of 2024 after also sprouting in 2022 and 2023. However, according to gingko tree vitality research conducted by tree doctors and other experts in spring, summer and autumn 2023, the leaves of some ginkgo trees begin to change color as early as June and July. We plan to report the findings of this vitality research in 2023 to the Environmental Impact Assessment Council.

We have been implementing appropriate measures regarding growth of the ginkgo trees based on findings of past vitality research. Details of the most recent remedial measures to restore the vitality of some of the gingko trees on the west side, implemented from April to June 2024, are described in the following release, which can be found on the project website.

In seeking to preserve the Four Rows of Ginkgo Trees going forward, we will review options with respect to remedial measures and other such actions that will restore the health of the ginkgo trees to their condition even prior to the start of the new baseball stadium construction, based on findings of the research and enlisting feedback from tree doctors and other experts.

We will refrain from providing responses from the developer regarding tree management carried out by the Tokyo Metropolitan Government.
Concerns have been raised regarding potential adverse effects on the rows of ginkgo trees as a result of the new baseball stadium being constructed in close proximity to the trees.
As such, what initiatives are being implemented to preserve the ginkgo trees?
We conducted the first root system research on the west side of the Four Rows of Ginkgo Trees in January 2023 and explained the situation to the Environmental Impact Assessment Council in July 2023. In the areas where root system research was conducted, findings with respect to all points of the research site did not pinpoint locations meeting the criteria presented in the main section of the assessment document in terms of there being four or more roots with a diameter of at least 30 millimeters within the bounds of a 10-centimeter section of mesh, which serves as a benchmark with respect to tree girdling. However, we conducted the second root system research in January 2024 in seeking to stringently conduct research given that concrete blocks, gravel, PVC pipes and other such elements have been identified at the site.
Based on results of the second root system research, we decided to set the distance from the sidewalk curb of the Four Rows of Ginkgo Trees to the underground framework of the new baseball stadium to approximately 18.3 meters (the “Setback Width”), thereby extending the distance by 10.3 meters from approximately 8.0 meters under the original plan. This will provide a better growing environment to preserve the ginkgo trees.
Please refer to the following release for specific details on root system research and Setback Width.

Going forward, we will proceed with plans for the new baseball stadium taking into account feedback from tree doctors and other experts.
Will root system research be carried out on all of the 146 trees in the Four Rows of Ginkgo Trees and the two rows along the Minato City road?
Root system research was carried out on the westernmost row of the Four Rows of Ginkgo Trees in 2023 and 2024 as part of considerations of where to locate the underground framework of the new baseball stadium in order to provide a better growing environment to preserve the ginkgo trees. As the research itself puts a certain strain on the trees, it was conducted using an appropriate number of samples based on consultation with experts, including tree doctors. Please refer to the following release for specific details.

Additionally, we plan to investigate the condition of roots about 17 meters away by hand approximately one year prior to the start of construction of the new baseball stadium and cultural exchange facility.

Also, regarding the 19 ginkgo trees along the Minato City road that are under consideration for transplantation, we plan to listen to the opinions of experts, including tree doctors, and to conduct detailed research based on consultation with relevant authorities so we can make a decision on whether to transplant them. Details such as the research methods and timing are under consideration but they will be disclosed along with the research results.
Some facilities of Jingu Stadium will presumably need to be downsized if the stadium is set back in order to preserve the Four Rows of Ginkgo Trees while the overall area of the site is left unchanged. As such, which facilities would be subject to downsizing?
The setback with respect to the new baseball stadium is to be as described in this Q&A. We intend to explore options in regard to specific details of facility plans, and accordingly have yet to make decisions at this point in time with respect to matters that include determining which facilities are to be subject to downsizing.
I have heard there are calls to have the Four Rows of Ginkgo Trees designated as a place of scenic beauty. Why haven’t you done so?
As a project developer, we are taking steps to ensure that each tree in the Four Rows of Ginkgo Trees is handled with care and properly protected. We are doing so not from a perspective of preserving a cultural property by aiming for the Four Rows of Ginkgo Trees to be designated as a place of scenic beauty, but with a view to developing the district, including the surrounding environment, in a way that will last 100 years into the future. Although our approach is different, the objective of protecting the Four Rows of Ginkgo Trees is the same.
Would you provide specific details on how you will deal with trees, particularly in terms of their removal, preservation, transplantation, and planting of new trees, with data on tree age, number, location, and species?
Also, would you explain your decision-making criteria and specific details in that regard, particularly in terms of impediments to transplanting trees?
Although records detailing the ages of the respective trees are lacking, we conduct individual tree research with respect to all of the tall trees located in the redevelopment site, including trees slated for preservation and transplantation. Details such as study findings as well as policies for preservation, transplantation, and removal are made available via the project website. Meanwhile, although the exact number of trees and their ages from 50 years ago within the redevelopment site are unknown, we provide equivalent information that includes respective tree heights and trunk circumference. For further details, refer to the relevant documentation (Japanese only).
https://www.jingugaienmachidukuri.jp/pdf/既存樹木調査データ.pdf
Under the redevelopment project, a total of 619 trees of a height of 3.0 meters and taller are subject to removal. A breakdown of such removal at the respective sites is as follows.
[23 trees in the vicinity of Kenkoku Kinen Bunko, 46 trees in the vicinity of Jingu No. 2 Stadium, 97 trees in the vicinity of Jingu Stadium, 40 trees in the vicinity of the rugby facility, 108 trees in front of the picture gallery, 7 trees in the vicinity of Four Rows of Ginkgo Trees, etc. (trees other than ginkgo trees), 153 trees in the vicinity of the tennis courts, and 145 trees at the site of the Itochu Corporation Tokyo head office building]
Plans call for removal, preservation, or transplantation of 142 tall trees in the vicinity of Kenkoku Kinen Bunko. This consists of removal of 23 trees, preservation of 75 trees, and transplantation of 44 trees. Whereas details of transplantation plans are under consideration, we primarily intend to ultimately transplant trees to the New Green Zone, which is near Central Plaza. Species of newly planted trees will be determined going forward, with management of the trees appropriately carried out by facility managers and others subsequent to project completion.
Decisions on trees currently located within the zone with respect to the options of preservation, transplantation, or removal, and with respect to the extent of transplantation difficulty, will be made by the project developers based on findings of the aforementioned studies and feedback from tree doctors. Details regarding arrangement of each and every tree have been made available via the project website. For further details, refer to the website link above. We plan to actively make use of trees requiring removal out of necessity.Please refer to the following release for information on the unavoidable reasons for tree removal.

Meanwhile, estimates have not been calculated with respect to oxygen release, effects on temperatures, and mortality rates of newly planted trees. However, we will appropriately maintain and manage the newly planted trees based on feedback from tree doctors and other experts, as is the case with trees slated for preservation and transplantation.
We understand that some trees need to be removed due to falling, death or ailment, or other factors. Will there be a public announcement about such trees?
With the passage of time, many trees weaken, others die or rot, or have branches broken in typhoons. To thoroughly ensure the safety of visitors, we routinely carry out preventative measures against fallen trees, broken branches, or the like, and over the past 15 years approximately 300 dead or ailing trees have been removed as we have made safety management for passing vehicles and pedestrians our highest priority.
When individual tree research was conducted in 2023, results confirmed 79 dead or ailing trees over the four years subsequent to the individual tree research of 2019.
The proposed revisions released on September 9, 2024, said that the total reduction in the number of trees to be removed was 124 and this includes 42 dead or ailing trees, but were these trees originally planned for removal? Also, at what stage were these trees judged to be dead or ailing and how was this decided? Please provide details, such as the location of the trees.
The 42 trees were originally planned for removal. These trees were judged to be dead or ailing based on the results of individual tree research conducted in 2023. The link below leads to results of the tree research and details can be found there.

On September 9, 2024, you released proposed revisions regarding further measures to preserve trees, etc., but does this mean the original plan was not good?
The initial plan was thoroughly thought out and as project developers, we have confidence in it. It carefully considered the situation of each individual tree and understood the ideals upon which Jingu Gaien was founded.
The September 2024 revisions aim to make even more sure that the trees are preserved and the decision to make changes also factors in damage including the impact of the construction plan.
I heard that 3,000 trees would be removed. How many trees will be removed overall, and how will shrubs be counted?
A total of 743 trees that are at least 3.0 meters tall will be removed. Of these, due to the demolition of Jingu No. 2 Stadium, we have applied for and received permission from Shinjuku City to remove 30 trees this year in February and 25 trees in September for a total of 55 trees in certain areas of the Scenic District in accordance with the Tokyo Metropolitan Government’s ordinance.

In addition, regarding trees and shrubs less than 3.0 meters tall, due to the demolition of Jingu No. 2 Stadium, we have applied for and received permission from Shinjuku City to remove 2,998 trees and shrubs in certain areas of the Scenic District this year in February in accordance with the Tokyo Metropolitan Government’s ordinance. For dense-growth shrubs that are difficult to count, such as azaleas, estimates are calculated based on the area taken up. Although we have not yet calculated the number of trees and shrubs to be removed in the entire district, we will follow the appropriate procedures in accordance with the ordinance for each construction area as we proceed with the plan. Please see the following release for more details, including how shrubs are counted.
Handling of trees in the Scenic District (Japanese only):
https://www.jingugaienmachidukuri.jp/pdf/jingugaienmachidukuri_news_2023032001.pdf

The redevelopment project plans to plant more new shrubs than the number removed, which will increase greenery from approximately 25% of the total area to approximately 30% after development. In addition, we will continue to consider ways to utilize trees and shrubs that have been removed.
What are the details of your transplanting plan? Also, have you conducted a soil environment survey or other such survey at transplant sites? If a survey has been conducted, please provide details.
To minimize the impact on the trees, we will transplant them at a suitable time, secure the planting base, implement irrigation and control transpiration of the planting base, install tree supports, and conduct appropriate tree management. Annual monitoring (vitality survey) will be conducted by a tree doctor, and if any changes are observed, we will respond appropriately by irrigating the trees and applying liquid fertilizer as needed.
Through appropriate management and cultivation, we will nurture greenery for the next 100 years.

The environment of the sites for transplanting and temporary transplanting were reported in the follow-up survey report (part 1 and part 2) in accordance with the environmental impact assessment procedures. Trees undergoing root preparation in the Kenkoku Kinen Bunko area will be transplanted to the north side of Kenkoku Kinen Bunko, in front of the picture gallery or in woodland around “Gokanbei Enoki,” or will be temporarily transplanted in the Jingu Gaien tree nursery.
Trees undergoing root preparation around Jingu No. 2 Stadium will be temporarily transplanted to the west side of the new rugby stadium site and in the Jingu Gaien tree nursery. They will also be planted in front of the picture gallery, in woodland around “Gokanbei Enoki,” and around the picture gallery.
In front of the picture gallery and to the west of the new rugby stadium site, we plan to secure a large area for transplanting, where planting soil will be spread as a base for a wide and continuous planting area. In transplantation sites within existing wooded areas (woodland around “Gokanbei Enoki” and the picture gallery), the soil is hard in many places, but the soil environment is of high quality, with good water permeability and biomass decomposition, which will allow the preparation of planting holes with sufficient space for root balls and backfill with a mixture of existing soil and bark compost. The Jingu Gaien tree nursery is located close to the project site. Trees and other plants owned by Meiji Jingu Gaien have been grown and managed in the nursery.

The plan calls for the transplantation of yaezakura (Japanese alpine cherry), momiji (maple), and shirakashi (Japanese white oak) in the Kenkoku Kinen Bunko, and matebashii (Japanese stone oak), shiinoki (Japanese beech), ubamegashi (ubame oak), keyaki (Japanese elm), yamamomo (Japanese bayberry), tokaede (trident maple), shiinoki, fuu (Formosan gum), kunugi (sawtooth oak), kusunoki (camphor), hitotsubatago (Chinese fringetree), and enoki (Japanese hackberry) in front of the picture gallery. In addition, we intend to plant hitotsubatago, shiinoki, karataneogatama (magnolia figo), mokusei (sweet osmanthus), sazanka (camellia sasanqua), mokkoku (ternstroemia gymnanthera), sangoju (sweet viburnum), inugusu (Japanese bay tree), tsubaki (camellia japonica), matebashii, and yamamomo in woodland around “Gokanbei Enoki,” and shiinoki and yamamomo around the picture gallery. Regarding temporary transplanting, we plan to transplant hitotsubatago in the Jingu Gaien tree nursery, and matebashii, shiinoki, keyaki, sangoju, and kobushi (magnolia kobus) at the west side of the new rugby facility site.
We plan to transplant trees already growing in each area to maintain the existing environment at transplant sites, with the exception of the following tree species: inugusu (woodland around “Gokanbei Enoki”), yamamomo (in front of picture gallery, woodland around “Gokanbei Enoki,” and around picture gallery), karataneogatama (woodland around “Gokanbei Enoki”), and kunugi (in front of picture gallery).
For further details on transplant locations, tree species, etc., please refer to the follow-up survey report (part 2), pages 34-37.
For results of the soil environment survey at the transplant sites and temporary transplant sites, please refer to the follow-up survey report (part 1), pages 91-93. (The same information is also available in the follow-up survey report [part 2], pages 314-316).

What are the details for your transplanting plan?
To minimize the impact on the trees, we will transplant them at a suitable time, secure the planting base, implement irrigation and control transpiration of the planting base, install tree supports, and conduct appropriate tree management. Annual monitoring (vitality survey) will be conducted by a tree doctor, and if any changes are observed, we will respond appropriately by irrigating the trees and applying liquid fertilizer as needed.
Through appropriate management and cultivation, we will nurture greenery for the next 100 years.

The environment of the sites for transplanting and temporary transplanting were reported in the follow-up survey report (part 1) in accordance with the environmental impact assessment procedures. The plan involves temporarily transplanting 12 species to the eastern side of the picture gallery site, including Japanese stone oak on the north side and sweetgum on the south side, and 7 species to the west of the new rugby facility site, such as Japanese stone oak and tea olive. A total of 9 species already planted in the transplantation site will be temporarily relocated, such as Chinese fringetree to the east side of the woodland around “Gokanbei Enoki” and Japanese stone oak to the west side.
Temporary relocation of trees before the final transplant is necessary to free up space for construction of the new rugby facility, except for the area where the trees are to be preserved in the Kenkoku Kinen Bunko. The area around the cultural exchange facility and Central Plaza, which is to be the main transplantation site, is currently occupied by Jingu Stadium and other facilities.

Please note that no specific contractor has been pre-determined for future phases of transplantation. We will select a contractor capable of appropriate transplantation based on the policies described in the environmental impact assessment report and follow-up survey plan.
What is the status and plan for transplanting the 19 ginkgo trees along the road leading to the Prince Chichibu Memorial Rugby Stadium? Why did you change your plan to consider transplanting the trees that were scheduled to be removed? Who will own and manage the trees after they are transplanted?
Although the 18 ginkgo trees lining Minato City road and 1 in the surrounding area were classified as level A or B in terms of vitality, many of them could not be considered healthy, as some had decayed branches and trunks or their roots had not grown sufficiently in the limited space of the planting zone along the sidewalk*. Although the original plan was to remove the trees, we are now considering transplanting the trees after conducting a detailed survey. We are considering transplanting the trees to the north side of the new baseball stadium before construction of the new baseball stadium begins. The timing and period of transplantation are still undecided.

* Detailed information about the condition of the trees in question is provided in the “Remarks” section of the “Survey data on existing trees (Japanese Only)” posted on the project website. The vitality rating is based on an average score of six items, but even if a tree is classified as level A or B, there may be decay on the branches or trunk.
[Survey data on existing trees (Japanese Only)]
https://www.jingugaienmachidukuri.jp/pdf/%E6%97%A2%E5%AD%98%E6%A8%B9%E6%9C%A8%E8%AA%BF%E6%9F%BB%E3%83%87%E3%83%BC%E3%82%BF.pdf

In 2022, we conducted an ultrasonic survey, and we will proceed with reporting the survey results and future transplantation plans, including survey methods, at the Environmental Impact Assessment Council.

We do not anticipate any re-transplanting after transplanting the 19 ginkgo trees.
We will proceed with a detailed study and plan for transplantation based on further research and the opinions of tree doctors, while referring to other transplantation cases.

In principle, the transplanted trees will be owned and managed by the owner of the land where they will be transplanted.
Looking at the tree data, what is your opinion at the current point of time regarding the 18 ginkgo trees lining Minato City road? Does the degree of difficulty in transplanting them relate to the state of their health? Or is it physically difficult to transplant the trees before the city road is closed? Or will transplanting be possible once the road has closed?
We are giving further consideration to the possibility of transplanting the 18 gingko trees lining Minato City road. Regarding the association between the timing of transplanting and the timing of the road closure, we believe there is no direct impact on surveys and consideration of the transplant plan. However, we do plan to remove some of the pavement surrounding the trees and confirm their condition in advance, and then consider the transplantation based on the opinions of tree doctors and others.
We plan to respond in a way to increase the possibility of transplanting to the maximum possible extent and will move forward in the future in discussion with relevant government organizations and the like regarding matters such as the survey timing and methods.
The “Survey data on existing trees (Japanese Only)” posted on the project website states that the 18 ginkgo trees leading to the Prince Chichibu Memorial Rugby Stadium cannot be transplanted, so I believe that cutting them down is unavoidable. You should consider the utilization of the felled trees. Also, what would be the hypothetical cost if you transplant the trees?
We are currently considering transplanting the 18 ginkgo trees after conducting a detailed survey. Please refer to this Q&A for details on the consideration of transplantation. The cost of transplanting the trees will be calculated based on the survey.
We will also consider optimal utilization of the trees that must be removed, while also paying attention to the environment.
Are there any concerns that transplanting will harm the health of the trees? How will the trees be managed?
The transplanting will take place under the supervision and guidance of a tree doctor during the appropriate season for planting and ensuring sufficient preparation for the roots. The trees will be transplanted after preparing a good planting base with consideration for the healthy growth of the root system based on the results of the soil environment survey. In addition, depending on their condition, we will use anti-rot agents and rooting stimulants on the cut parts of branches, secure the trees with supports, and promote healthy establishment by thoroughly watering the trees with irrigation equipment.

After transplanting, the trees will be regularly monitored by tree doctors, and necessary measures will be taken according to the condition of the trees and reported in a follow-up survey report.
For more information, please refer to p. 48 of the Environmental Impact Assessment Follow-up Survey Report (Construction in Progress Part 1) (Japanese only).
https://assess-toshokohyo.metro.tokyo.lg.jp/uploads/web_public/357_jinngugaien/21/21202335712.pdf
Is there any possibility of using municipally owned land as a transplantation site?
The plan for transplanting trees, including the transplantation sites, is described in the environmental impact assessment report (link below) in accordance with the Tokyo Metropolitan Environmental Impact Assessment Ordinance and reported to the Environmental Impact Assessment Council (Japanese only).
https://www.kankyo.metro.tokyo.lg.jp/assessment/information/toshokohyo/publishdetail/357_jinguugaien_tosho_sho.html
The document “Conservation of Jingu Gaien’s Greenery,” sent out by the Shinjuku City Mayor on April 4, 2023, made the following statement: “If difficulties are encountered in transplanting the trees that have existed since the founding of the Jingu Gaien around the Kenkoku Kinen Bunko, we will work together so that the historical atmosphere of the Jingu Gaien area can be preserved for the future, such as by transplanting the trees to municipally owned land.” However, there is currently no plan to transplant trees outside the Jingu Gaien area. We will continue to discuss this with administrative agencies as necessary.
Wasn’t Jingu Gaien designed to be a sustainable natural forest, in which one generation of trees is replaced by the next through the forces of nature, with minimal human intervention?
Meiji Jingu is composed of the Inner Gardens which maintain a dignified and solemn appearance centered around the shrine, and the Outer Gardens which are open to the public and many people come and go.
While the Inner Garden’s forest grows naturally and renews itself without human intervention, the trees in the Outer Garden which are the subject of the redevelopment project grow along with public use and are maintained and managed by human hands to protect the safety of visitors. There are many old trees in the Outer Garden, and over the past 15 years, approximately 300 dead or ailing trees have been removed and approximately 600 trees replanted. In addition, more than 50 tall trees have fallen due to typhoons and snowfall during this period, and broken branches and other problems must be frequently dealt with in daily management.
The redevelopment project therefore makes the safety of visitors its top priority and will also renew the greenery for the next 50 and 100 years.
In the redevelopment project, the green zone on the east side of the rows of ginkgo trees, which has the largest amount of greenery in the area, will be preserved, and the trees planted in the Kenkoku Kinen Bunko and other areas will be preserved or transplanted as much as possible, while all Four Rows of Ginkgo Trees will be preserved.
Please tell us about the tree donations that will take place under the redevelopment project.
Meiji Jingu Gaien was formerly built through monetary donations and donated trees from the public under the call of people including Eiichi Shibusawa, and continues to be used to this day. Over many years, it has been renewed through human labor and opened to the public as a green space and cultural and sports facility, and has been enjoyed by many people.
We are conducting the Reiwa Tree Donation Program as one of the initiatives for citizens who agree with and wish to participate in our efforts to create new greenery for the next 100 years. Details can be found on the Reiwa Tree Donation Program official site. https://gaien-midori-project.jp/ (Japanese only)
For how long and in what capacity will the developers be responsible for the preservation of trees in the Outer Garden?
As the developers, we have reported an impact assessment of the preservation of greenery to the Environmental Impact Assessment Council of the Tokyo Metropolitan Government, and we will continue to report regularly during the construction period until the project is completed in the form of a follow-up survey report. In the event that results differ from our projections, we will take the necessary measures according to the condition of the trees and report the results in the follow-up survey report as we proceed.
After construction is completed, the managers of each facility will take over the responsibility to manage them appropriately.
What will happen to the Kenkoku Kinen Bunko forest after redevelopment?
What are your thoughts on the view that “Kenkoku Kinen Bunko is not a forest”?
Of the 142 trees currently located in the Kenkoku Kinen Bunko, 75 will be preserved as is and 44 will be transplanted, for a total of 119 trees (over 80%) to be preserved or transplanted. The north side of the Kenkoku Kinen Bunko site will be left as it is to preserve greenery. Approximately 112 trees will be transplanted from the Kenkoku Kinen Bunko location and other sites to the area around the cultural exchange facility and Central Plaza, and new trees will also be planted to restore the woods and ecosystem of the Kenkoku Kinen Bunko.
We are aware that Kenkoku Kinen Bunko is called “Kenkoku Kinen Bunko forest” by some people, but since its establishment, it has been recognized as a green space where Kenkoku Kinen works are located. The site area of Kenkoku Kinen Bunko (approx. 5,000 m2) is approximately 1.7% of the total project area (approx. 28.4 hectares), and differs from the large forested area of Meiji Jingu Naien, which is naturally renewed without human intervention.
How will you announce any future changes regarding the handling of trees, such as a decrease in the number of trees to be removed, or a change of plan from transplanting to removal?Please tell us the latest status, as of May 2024, of the breakdown of the preservation, transplantation and removal status of the 1,904 trees listed as the current state on the Care and Handling of the Trees page on the project website.
As explained in a news release dated September 29, 2023, before we start removing trees at the site for the new rugby facility, we will disclose detailed revised statements regarding the preservation of trees based on the results of the studies conducted in the environmental impact assessment report, and will report the revised statements and proposed changes to the Environmental Impact Assessment Council and publish them on the project website.

The design plans for the tennis courts in front of the picture gallery and the plaza in front of the picture gallery are underway, and as with the new rugby facility, further consideration is being given to the preservation and handling of existing trees, and will be announced as soon as they are finalized.

Going forward, we will continue to consider the further preservation and handling of existing trees in areas other than the plaza in front of the picture gallery, and any changes will be announced appropriately on the project website and through other means after taking the necessary procedures required by laws and regulations.

→September 9 postscript: The proposed revisions above have been disclosed in the following release dated September 9, 2024.

Why are you applying for permission to remove trees in stages, rather than all at once?
In order to apply for permission to remove trees in accordance with the Tokyo Scenic District Ordinance, accurate information on the trees applied for is required, so we will apply appropriately at the time when the actual removal is necessary.
Will the trees purchased with donations from the Reiwa Tree Donation Program be distinguished from other trees? If I donate to the program, will I receive any preferential treatment for participation in tree-planting events?
Donations are used to purchase trees and to plant, cultivate, and manage the trees purchased. There are no plans to distinguish or indicate which trees have been purchased with donated funds. The developers will select and plant trees of the appropriate species and age while taking into consideration the vegetation in each area, and they will carefully manage these trees along with the rest of the trees.
As stated in the terms of agreement in the donation application procedures, there are no plans to offer preferential treatment, such as participation in events, to those who make donations.
Will reports on the activities of the Reiwa Tree Donation Program be made public?
The total amount, number of donors, and intended use of donations will be announced through the project website and other means. The timing and specific method of announcement are still under consideration.
In the “Survey data on existing trees (Japanese Only)” posted on the project website, all trees have been numbered sequentially, but some numbers have been skipped. How many have been skipped, and why?
To maintain consistency with the daily management operations of Meiji Jingu, the survey data numbering includes trees less than 3.0 meters tall. The missing numbers are mainly the numbers of the trees less than 3.0 meters tall or those that have been cut down in the course of normal maintenance*, which are not included in the individual tree research of the environmental impact assessment report for this project. There are approximately 600 of such trees.
* Jingu Gaien has been properly maintained and managed through human labor over the years to reach its current state, and its trees have been replaced over the course of its history. Many of the trees have weakened with age, as well as damage inflicted by past facility renewals and natural disasters. To ensure the safety of visitors, daily measures are being taken to deal with fallen trees and broken branches. Over the past 15 years, approximately 300 dead or ailing trees have been cut down for the safety of passing vehicles and pedestrians, and approximately 600 trees have been replanted.
According to the “Survey data on existing trees (Japanese Only)” posted on the project website, the species with the largest number of existing trees is the Chinese juniper (204 trees). Of these, 20 trees are slated for “preservation” and “transplantation,” respectively, while 164 trees are slated for removal.
Meanwhile, 44 of the 99 Japanese zelkova trees, which are over 10 meters tall and believed to be over 100 years old, are to be cut down, as well as 50 of the 73 Himalayan cedar trees.
I believe these trees are being cut down because they are obstructive trees that will interfere with the construction of the facilities. Is that correct?
Trees are cut down primarily because current facilities hinder the excavation of sufficient root balls necessary for transplantation, or because the trees lack the vitality to withstand transplantation. We aim to transplant trees that would interfere with future facilities whenever possible. For trees that require removal due to difficulties in transplanting for the aforementioned reasons, we will consider ways to put them to optimal utilization with attention to the environment.
This upgrade and repositioning of facilities includes an increase in greenery across the entire Jingu Gaien site and I am looking forward to the establishment of a plaza surrounded by greenery that can be used freely by citizens. Regarding plans to create new greenery, why are you fixated on transplanting existing trees rather than planting new ones that fit in with the soil environment and scenery, including young trees that will absorb large volumes of carbon dioxide over the long term?
The policy of the plan is to handle each of the existing trees with care and to preserve them as much as possible. For trees that cannot be preserved in their current place, we try to transplant them somewhere within the site. Trees are only removed for unavoidable reasons, such as if they were planted in the area around a facility or have become too weak to save. We also strive to reduce the removed trees as much as possible and to reuse the wood after removal. Going forward, we will create the Jingu Gaien greenery so that it can become more beloved to an even greater number of people over the next 100 years.
Jingu Gaien is home to multiple hitotsubatago trees (chionanthus retusus). Many are thought to have been cultivated from seeds and planted as young trees in the Edo period, making Jingu Gaien an important natural habitat for hitotsubatago.
Can you develop a plan to avoid the removal of these trees, which have been growing at the site continuously since the Edo period. In addition, for the purposes of transparency, we would like a clear record of all the trees to be removed.
A tree survey conducted in the early Showa period recorded a dozen or more hitotsubatago trees in Jingu Gaien. Most of the hitotsubatago trees we see today were planted later, in the 1950s, as part of the daily management of the gardens.
Regarding the species of trees to be removed and the handling of the hitotsubatago trees, out of a total of 70 trees, 45 will be preserved, 20 transplanted, and 5 removed (including 2 dead trees), with the majority of trees to be preserved or transplanted, as stated in the existing tree survey data (survey / vitality survey of individual trees [2023]) available on the official website (Japanese only).
https://www.jingugaienmachidukuri.jp/pdf/%E6%97%A2%E5%AD%98%E6%A8%B9%E6%9C%A8%E3%83%87%E3%83%BC%E3%82%BF%EF%BC%882023%E5%B9%B4%EF%BC%89.pdf
The removal of trees started on October 28, 2024, but do you have a plan for using the removed trees?
Also, is it possible for regular people to receive some of this wood?
Under the project, each and every tree is handled with care, and consideration is taken to preserve as many trees as possible. Trees that are judged to be difficult to preserve in their current state will be transplanted.
However, we remove trees deemed not viable for transplantation and trees not likely to maintain healthy tree growth and shape after transplantation because of unavoidable reasons such as “designation as a priority control invasive alien species,” “proximity to existing facilities preventing necessary preparation for transplantation,” or “weak tree vitality.”
Removed trees are being handled following consideration of appropriate ways of using them that take into account environmental factors. The environmental impact assessment report describes “there will be active consideration of appropriate ways of using the removed trees that takes into account environmental factors. Uses could include creating benches and commemorative goods, or making wood walkways, fertilizer or woodchips.” Specific ways that the trees will be used are currently under consideration, and any decisions will be disclosed through the official website and other channels.
The transplantation and removal of trees started on October 28, 2024, so please disclose the schedule for upcoming work on the official website.
The schedule for upcoming transplantation and removal work is subject to change based on factors such as daily weather and appropriate transplantation timing, so we have no plans to disclose it. We ask for your understanding on this matter.

Impact on the natural environment

Please tell us the estimated amount of CO2 emissions from construction and other activities in the redevelopment project, the impact on total CO2 emissions due to changes in the greenery, and the amount of waste that will be generated.
We have not been able to determine the overall actual emissions because we are unable to calculate CO2 emissions from pre-existing buildings in this area. We estimate that annual CO2 emissions subsequent to development will be approximately 47,000 tons. We will continue our efforts to pursue decarbonization through various measures such as the maintenance of district heating and cooling systems and the proactive use of renewable energy. We have not calculated CO2 emissions related to tree preservation, transplantation, removal, or planting.
Please refer to the relevant pages of the environmental impact assessment report for surveys, forecasts, and evaluations related to waste and greenhouse gases.

Greenhouse gases (Japanese only): https://assess-toshokohyo.metro.tokyo.lg.jp/uploads/web_public/357_jinngugaien/06/06202235720.pdf
Mitsui Fudosan and Nikken Sekkei have formulated the “Manual for Calculating Greenhouse Gas (GHG) Emissions” for construction. Will emissions in the redevelopment project be calculated according to the manual?
For the buildings in which Mitsui Fudosan will be the project owner in the construction of the redevelopment project, we plan to study the emissions in accordance with the “Manual for Calculating Greenhouse Gas (GHG) Emissions” for construction formulated by Mitsui Fudosan and Nikken Sekkei. The results of the calculations will be made public at a later date.
How will you update data in the environmental impact assessment report?
We began a tree vitality survey in May 2023.
Other factors will be reported in the follow-up survey report in the environmental impact assessment procedures, and will also be made public on the official web site.
How will the ecosystem be changed, particularly in the Kenkoku Kinen Bunko forest?
Predictions and evaluations regarding the redevelopment project’s impact on the natural environment are disclosed in the environmental impact assessment report. For details, please refer to the environmental impact assessment report available on the Tokyo Metropolitan Government’s official website.
Biological ecosystem (Japanese only): https://assess-toshokohyo.metro.tokyo.lg.jp/uploads/web_public/357_jinngugaien/06/06202235712.pdf

Our plan is to preserve as many trees in the Kenkoku Kinen Bunko as possible, either by leaving them where they are or transplanting them, but some will be transplanted or removed because they are located on the site where the new rugby facility is to be built. The transplanted trees will mainly be located in the new wooded area around the Central Plaza. Newly planted trees will be placed to restore a cohesive plant community with a hierarchical structure around the Kenkoku Kinen Bunko. For more details, please refer to p. 346 and other pages of the environmental impact assessment report posted on the Tokyo Metropolitan Government’s website.

https://www.kankyo.metro.tokyo.lg.jp/assessment/information/toshokohyo/publishdetail/357_jinguugaien_tosho_sho.html
The development project is expected to affect the area around the Akasaka Palace in terms of shade, wind, and noise. Has the Imperial Household Agency been briefed on the project or given its approval?
We are conducting surveys, forecasts, and evaluations with respect to the environmental impact of the project in terms of shade, wind, noise and other impacts as part of environmental impact assessments.

For details, please refer to the environmental impact assessment report available on the Tokyo Metropolitan Government’s official website (Japanese only ).
https://www.kankyo.metro.tokyo.lg.jp/assessment/information/toshokohyo/publishdetail/357_jinguugaien_tosho_sho.html

As part of the Tokyo Metropolitan Government’s environmental impact assessment procedures, a briefing session on the draft of the environmental impact assessment was held in August 2021 for relevant communities*. However, we are unable to answer questions about individual responses to the draft assessment.
* The development project’s relevant communities have been determined by the Governor of Tokyo in accordance with Article 49 of the Tokyo Metropolitan Government’s Environmental Impact Assessment Ordinance. These communities are as follows:
Minato City: Kita-Aoyama 1-chome, Kita-Aoyama 2-chome, Kita-Aoyama 3-chome, Minami Aoyama 1-chome, Minami Aoyama 2-chome, Minami Aoyama 3-chome, Minami Aoyama 4-chome, Moto-Akasaka 2-chome, Akasaka 8-chome
Shibuya City: Sendagaya 1-chome, Sendagaya 2-chome, Sendagaya 3-chome, Sendagaya 6-chome, Jingumae 2-chome, Jingumae 3-chome, Jingumae 4-chome
Shinjuku City: Kasumigaoka-cho, Shinanomachi, Minami-Motomachi, Daikyo-cho, Naitomachi
Are you creating and submitting environmental impact statements?
Under the Tokyo Metropolitan Government’s Environmental Impact Assessment Ordinance, if the project developer is a private sector entity, as it is in this project, then procedures for planning stage environmental impact assessments, including environmental impact statements, do not apply. Therefore, we are not creating and submitting them.

Disaster preparedness

What is the estimated area, location, and number of people who can use the area as a wide-area evacuation site? Please also tell us about the temporary shelters in the official web site as a measure for people who are unable to return home when a disaster strikes
(1) Wide-area evacuation site
The Jingu Gaien District and the surrounding area have been designated as an evacuation site by the Tokyo Metropolitan Government in accordance with the Tokyo Metropolitan Government Ordinance on Earthquake Disasters Countermeasures to protect people in the area from fires that may spread in the event of an earthquake. The site is planned to accommodate 80,983 people as of July 2022, and the effective evacuation area per person is 4.37 m2/person. As a developer, we anticipate that the area will be large enough to accommodate an estimated additional 13,000 people using the evacuation site during the daytime.
In addition, we envision that buildings such as the new sports facilities and mixed-use buildings may be used as a temporary shelter for people who are unable to return to their homes. These facilities will be designed to accommodate people for up to 72 hours after a disaster occurs.

(2) Temporary shelters for people unable to return home when a disaster strikes
Under the redevelopment project plan, we plan to prepare space to accommodate approximately 5,000 people within the entire area of approximately 9,000 m2, as well as a disaster stockpile warehouse, and plan to provide water and blankets to people unable to return home who are there temporarily.

Furthermore, we plan for buildings such as the new sports facilities and mixed-use buildings to be used as temporary shelters for up to 72 hours after a disaster occurs.
What are you envisioning regarding disasters such as earthquakes, fires, and typhoons?
The redevelopment official web site is designated as a fire prevention district and a quasi-fire prevention district under the City Planning Act, and we will ensure that buildings are highly fire-resistant in accordance with laws and regulations, so we believe that fires will be virtually impossible to spread.
Since the Jingu Gaien District and the surrounding area have been designated as an evacuation site by the Tokyo Metropolitan Government in accordance with the Tokyo Metropolitan Government Ordinance on Earthquake Disasters Countermeasures to protect people in the area from fires that may spread in the event of an earthquake, we anticipate that people in the surrounding urban area outside the official web site will use open spaces such as the plaza for temporary evacuation. In addition, since the official web site is close to a subway station and there may be people who are unable to return to their homes in the event of an earthquake, we anticipate that buildings will be used as temporary shelters for such people.
In designing each facility, we will pay sufficient attention to ensure the safety of all facility users and those passing through, even in the event of a disaster.
Will the Jingu Stadium deck (pedestrian bridge) be wide enough?
The width of the north-south deck No. 3, which is the pedestrian bridge in question, will be 6.0 to 10.5 meters wide. In deciding the width, traffic volume projections were made through simulations, taking into account the events to be held at the Japan National Stadium. We have confirmed its safety under the assumptions of level A (free walking) or B (slightly constrained), the most favorable of the five levels of service in the traffic planning manual for large-scale development areas by the Ministry of Land, Infrastructure, Transport and Tourism.
Even in the case of service level B, there is only a slight limitation in free walking, and the predicted results show no safety concerns.
Tell us why developers did not disclose or explain the details of the project until the NHK program on April 5 and did not respond to earlier media requests for information. Also, it was explained during the program how an important purpose of the redevelopment was to protect the greenery of Naien (inner garden), but I think an extremely important purpose of this redevelopment and facility renewal project is to ensure the safety of facility users. Tell me why there was no explanation on eliminating inadequate evacuation routes in disasters due to the narrowness of the roads.
As of the present, as developers, we have responded to various media, provided information on the project website, responded to questions and disclosed information, and held information sessions for local residents to properly convey the project plan and have focused on ensuring it is understood. At the same time, the methods for providing information have been various, and we understand that information is not always adequately conveyed. It is important that such communication be ongoing and we will continue to work to actively provide information.
In addition, about improving disaster preparedness, as you have pointed out, it is one of the important purposes of the redevelopment project, and our response is provided on the project website, as well as here in this Q&A. In the interview in this media report as well, it was explained how improving disaster preparedness was one of the purposes of the project, but the broadcaster ultimately decides what to air. Based in part on what you have pointed out, we will provide information so that there is a firm understanding of improving disaster preparedness going forward.
In regard to the plaza in front of the picture gallery subsequent to development, a comment was previously made at the Tokyo Metropolitan Government City Planning Council about the prospect of ensuring that the location contributes to greater disaster resiliency by equipping the site with a helicopter staging area for medical and disaster operations. What information are you able to release to the public with respect to options currently under consideration along those lines?
Design work pertaining to the development plan for the plaza in front of the picture gallery is currently underway. We are in the process of reviewing specifics regarding helicopter takeoff and landing, as well as operation of a staging area, but decisions on the matter have yet to be made at this point in time. We will continue to explore options on how the location might contribute to better disaster resiliency in serving as a wide-area evacuation site.

Community information session

How did you determine the scope and venue of the community information session held in July 2023?
Please provide an explanation of the project for the wider public.
In order to carefully address questions and concerns, we have used an informational video, Q&A, and community information session.
The information session is held at our discretion and is not enforced by any ordinance. We determined the approximate scope to include those living in the area from the redevelopment official web site’s outer boundary to the distance twice the maximum building height (approximately 190 meters) in the project area. This scope was set with reference to past examples of general construction briefings and briefings for Tokyo Metropolitan Government’s Special Urban Revitalization District proposals.
The venue for the information session was determined after confirming the availability and size of several venues in the vicinity of the official web site. Of the approximately 13,000 households in the project area, a total of 381 people attended.
For those who were unable to attend the information session, a video of the same content presented at the session is available on this project website. Please watch the video, and if you have any questions, feel free to use this question form.
How were the speakers for the community information session selected?
Each of the four developers and a consulting firm appointed the necessary personnel as speakers to explain the project.
Did you encourage local schools to participate in the community information session?
We announced on the project website that individual explanations would be provided to schools (including PTAs) whose school districts are located in the scope of the July 2023 community information session, as well as to city councils and neighborhood associations within the scope, if requested.
I have heard that the redevelopment plan was drawn up by the government and project developers without the consent of local residents. With many residents having voiced opposition, what have you been doing to facilitate dialogue with residents?
Also, I have misgivings particularly given that the project involves use of taxpayer funds yet confirming the desires of residents is not a priority, and also given that the project involves construction of high-rise buildings. I am apprehensive regarding the notion that the project gives precedence to politicians with vested interests who are engaging in administrative practices and allocating budgets in a manner that disregards the future of residents.
As stated in this Q&A, the redevelopment project is being promoted by four developers, namely Mitsui Fudosan Co., Ltd., Meiji Jingu, Japan Sport Council (JSC), and Itochu Corporation, and there are no plans to seek subsidies or grants from the national government, Tokyo Metropolitan Government or municipalities.
When it comes to engaging with residents, the developers have held a total of nine briefing sessions thus far as required for urban planning procedures stipulated under ordinances and other rules, along with discretionary briefing sessions*1. They have also been providing individual explanations for local community associations, schools and other such entities upon request.
Additionally, the Tokyo Metropolitan Government has established a task force consisting of academic experts and government officials under its “Guidelines for the Urban Redevelopment of the Jingu Gaien District in the post-Tokyo 2020 Olympic and Paralympic Games Era.” The guidelines serve as a master plan superseding the redevelopment plan and were drawn up taking into account feedback provided by Tokyo residents through a call for comments from the general public. Moreover, we act in accordance with the Tokyo Metropolitan Government’s Environmental Impact Assessment Ordinance in making proposed environmental impact assessment reports available for public inspection and seeking feedback on such content, seeking feedback from the public by holding forums to solicit input from Tokyo residents, and releasing written opinion and views of project developers regarding such content.
Also, in striving as project developers to ensure that an extensive audience gains an understanding of the redevelopment plan, we have equipped the project website with a question submission page. The website enables the general public to submit questions regarding the redevelopment project and enables them to access views of the project developers, which we release regularly*2.
*1. Please see the following release dated May 29, 2024, for details regarding results of briefing sessions and other such forums.
https://www.jingugaienmachidukuri.jp/pdf/en-jingugaienmachidukuri_news_2024052902.pdf

*2. As of July 12, 2024, we have provided responses to a total of 427 questions.
Why was the briefing for residents on September 28, 2024 only open to people who live or have addresses in Shinjuku and Minato wards? Will you not be holding briefings for people who live or have addresses in places other than Shinjuku and Minato wards (such as Shibuya)?
Also, do these briefings contribute to gaining the residents’ understanding?
We held the briefing because Shinjuku and Minato wards, where the development project is located, asked us to hold a briefing session for the general public. Eligibility to attend the briefing was not arbitrarily determined by the developer.
The content of the briefing was identical to the press release issued on September 9, 2024. For more information, please refer to these materials:

(1) Informational Video about the Jingu Gaien District Urban Redevelopment Project (video released July 1, 2024)

Since September 9, 2024, as one of the developers, we have been widely disseminating the press release through the media to ensure it reaches as many people as possible. The release and an explanatory video were also published on the official website. As before, responses will be provided to any questions and opinions regarding the content of the release submitted via the official website or to the Jingu Gaien District Redevelopment Project Planning Office.

Additionally, we also consider holding individual briefings at the request of local schools (including PTAs), local assemblies, and community associations, so please contact the Project Planning Office to make such a request.

We will continue to provide information concerning the project and work to gain the understanding of stakeholders by listening and responding to opinions and questions like this, providing individual briefings, and other methods.
I am a Shinjuku Ward resident who attended the briefing in September 2024. The recent briefing session covered Shinjuku and Minato wards, but will you hold another briefing session if requested by the Shinjuku Ward local assembly?
The briefing on September 28, 2024 was held at the request of Shinjuku and Minato wards and covered those wards. As stated in our response in this Q&A, if we receive requests from local schools (including PTAs), local assemblies, or community associations, we will consider holding individual briefing sessions. Please contact the Jingu Gaien District Redevelopment Project Planning Office. Please note, information provided at briefing sessions is also available on the official website, and we welcome your questions via the Q&A page.

Miscellaneous questions / Glossary

What systems are being used to promote this plan?
This plan is being promoted through the “Parks and Community Development System,” “district plans that stipulate redevelopment promotion areas,” “Type-1 Urban Redevelopment Project,” and other systems.
What does a town management organization do?
“Town management” or “area management” generally refers to a proactive approach to community development involving collaboration among various stakeholders in a town, such as business operators, landowners, and local residents.
The town management organization planned for this district will be led by business operators and landowners and will promote activities to create an attractive town by taking advantage of features such as large-scale sports facilities and open spaces. As part of these activities, we are planning to hold interactive events that will help people become familiar with Jingu Gaien, and we hope that such events will enable a wider range of people to enjoy the new Jingu Gaien. Details of these activities will be announced through this website and other means.
What is the Parks and Community Development System?
The Parks and Community Development System solves community issues and provides comfortable urban environments with greenery and open space, balancing community development and the maintenance of parks and natural areas. Development is conducted by the private sector in city-planned parks and natural areas, including those that have been unused for a long time (parks that are freely accessible and usable by all are considered “used areas,” and those that are not are called “unused areas”).
What are environmental impact assessment procedures?
Based on the Environmental Impact Assessment Ordinance, developers are required to conduct surveys, forecasts, and evaluations of environmental impacts in advance, prepare an environmental impact assessment report, and comply with tree preservation, the creation of visual aesthetics, and consideration for the surrounding environment as stated in the assessment report. These procedures are called the “environmental impact assessment procedures” or “environmental assessment.”
How can I submit a question about the project?
If you have any questions or comments, please contact us via the following information desk. (Please note that assistance will be provided in Japanese only)
Information Desk,
Jingu Gaien District Urban Redevelopment Project Planning Office
TEL 03-6695-0539
Who are the members of the town management organization? Will local residents be included?
For the initial stages, we are considering a town management organization under the assumption that the four developers will participate. In February 2023, a preparatory group was established by the four developers to work out the details. When the town management organization is established, it will be announced on this project website.
We expect the town management organization to actively be involved both on a regular basis as well as during times of disaster and when events are held. We would like to invite local residents to participate in certain activities, depending on the content, such as community events.
How will the Jingu Gaien Fireworks Festival and Jingu Stadium fireworks be held in the future?
Since the construction area will change throughout the various stages of redevelopment, we will discuss this matter with the event organizers each year. Subsequent to development, we will discuss the location and scale of the fireworks events with the organizers based on the layout of the facilities.
Will you be changing the project plans in light of the considerable amount of opposition received? Will the Environmental Impact Assessment Council not review the project?
As the developers, we take criticism very seriously. We believe that one of the reasons for the criticisms is the lack of communication from the developers to properly convey our plans to the public. Although it is difficult to respond to all comments individually, we held a face-to-face meeting in July 2023 and received comments and questions directly from the participants. In order to gain understanding and dispel any misunderstandings, we will continue to redouble our efforts on disseminating information, including the release of the informational video and materials from the July meeting.
As we believe that the redevelopment project holds great significance, we have been advancing the project in accordance with the appropriate procedures. Since the project has already been approved, it may be difficult to make major changes, such as those involving the layout and size of buildings. However, we will continue to consider ways to improve the development in light of administrative guidance and the opinions of the public.The operational phase environmental impact assessment procedures have been completed, and based on the environmental impact assessment report, we will continue to report to and discuss with the general meeting of the Council and other relevant organizations while proceeding with the project in an appropriate manner.
In September 2024, we released proposed revisions of facility design plans and other aspects of furthermore ensuring preservation of trees. Please see the following release for details regarding the proposed revisions.

There have been social media posts attacking the developers. I don’t think the developers have responded sufficiently.
The developers’ failure to take decisive action has escalated the situation, resulting in petitions gathering many signatures.
As one of the developers, how will you respond to this situation?
As the developers, we are aware of actions that may be considered unfair and of the problematic spreading of information. We will consider taking action on a case-by-case basis if deemed necessary.
Is TEPIA included in this development plan? If not, what is the reason?
In 2015, the Tokyo Metropolitan Government and six related rights holders signed a memorandum of understanding for urban development. TEPIA participated in the discussions but ultimately decided not to participate in the project.
How and to what extent do you expect the creation of this bustling area to impact the surrounding neighborhood?
How can its liveliness benefit the citizens?
Please explain in detail.
The benefits to the neighborhood include the increase of open space and improved pedestrian access that will facilitate going and coming between the Rows of Ginkgo Trees and Stadium Street, as well as improved indoor spaces such as sports facilities and offices, and increased disaster preparedness as an evacuation site with enhanced facilities to accommodate people who are unable to return to their homes.
Currently, many people visit the large-scale sports facilities and other buildings. However, the redevelopment project aims to transform the entire area into more versatile facilities and spaces and revitalize it as a place where many people can relax and visit even when events are not being held at the large-scale sports facilities.
The images and perspective drawings of the Jingu Gaien redevelopment on the official web site are distant views from Jingu Stadium or bird’s-eye views from the sky, which do not convey the currently overcrowded feeling that the existing buildings and hotel impart to the baseball stadium or the fact that the project will significantly change the landscape of Jingu Gaien.
It is also difficult to imagine the landscape from a pedestrian’s perspective (eye level), especially the view when walking through the Four Rows of Ginkgo Trees and the view from Aoyama-dori Avenue overlooking the picture gallery.
Can you show us an illustration of the completed project that is easy for everyone to understand?
The perspective drawing of the entire project that is currently available on the project website has been created from a bird’s-eye view so that the entire project can be seen from an easy-to-understand angle. We understand that there are some disadvantages to the bird’s-eye view angle, such as the difficulty in understanding the view at eye level, so we will consider how to present future illustrations of the completed project more clearly in light of the comments we receive.
In addition, the environmental impact assessment report forecasts and evaluates the future landscape image using a collage of current photos taken at eye level and other presentation methods. For details, please refer to the relevant section of the environmental impact assessment report available on the Tokyo Metropolitan Government’s website.
Visual impact (Japanese only): https://assess-toshokohyo.metro.tokyo.lg.jp/uploads/web_public/357_jinngugaien/06/06202235716.pdf
What will happen to the Shinjuku City road between the Kenkoku Kinen Bunko forest and Jingu No. 2 Stadium?
What will happen to the trees along Shinjuku City road?
What will happen to the Minato City road at the entrance to the rugby facility?
The Y-shaped Shinjuku City road on the north side of the current Jingu No. 2 Stadium will be closed before the new rugby facility is constructed. There are no trees along Shinjuku City road.
The Minato City road between the Jingu Gaien Tennis Club and the Prince Chichibu Memorial Rugby Stadium will be closed and replaced by the new baseball stadium.
Will the sidewalk (metropolitan road) surrounding the plaza in front of the picture gallery be maintained in its current state? Will the sidewalk (metropolitan road) around the plaza still be able to be used for running or jogging after the redevelopment?
The sidewalk (metropolitan road) surrounding the plaza in front of the picture gallery will basically be maintained and we believe it will be usable for running or jogging after redevelopment.
Have you conducted research on precedents set by other regions with regard to urban redevelopment and city planning? Are you collaborating with academics specialized in fields such as parks and natural areas, city planning, and disaster prevention? If so, please provide specific names, accomplishments, and references.
In the redevelopment project, we have been moving the plan forward while taking into account the opinions of academic experts specializing in fields such as parks and natural areas, city planning, and disaster prevention, and as necessary, we have sought the opinions of multiple tree doctors and other experts (i.e., experts who were involved in the establishment of the arborist system and have experience in numerous soil and root system surveys, as well as experienced tree doctors). We will continue with the same approach, incorporating the knowledge of experts as necessary to achieve a better plan.
Please refer to the following release dated September 9, 2024, for further tree preservation proposals as well as details with respect to tree doctors and other experts who provided opinions in the course of exploring options for proposals on preserving trees.

What will happen to the stone mounds of the Kasumigaoka Gate and the Prince Chichibu Memorial Rugby Stadium?
They will be temporarily removed and stored during the demolition work, and their placement will be discussed when the entire urban development project is completed.
Can you provide a detailed explanation of the project and explain how the area will be operated after redevelopment is completed?
We have received several questions regarding the project and post-completion operations, such as pavement specifications, solar panel installation, and greening plans. However, there are many details regarding the project and its operations that have not yet been decided. Such details will be determined as planning progresses.
How many years will each of the newly constructed facilities be used for? When will the next phase of renovation or reconstruction take place?
We plan to replace existing aging sports facilities in phases, and together with facilities that will create a bustling atmosphere, we plan to develop and maintain them as a hub for international culture and sports that will last for the next 100 years. The timing of the renovation and reconstruction of the new facilities has not yet been determined.
How many questions have you received so far?
From July 17, 2023 to August 25, 2024, we have received 464 questions and 117 comments. We are posting answers to these questions in stages and aim to continue posting answers roughly twice a month to address incoming questions. We will also publish the number of questions and comments we have received so far on the “News” page below. (Applicable articles are available in Japanese only)

There have been posts on social media regarding the 18 ginkgo trees lining Minato City road, saying that they are hard to preserve and transplant, so they will be cut down. Is this true? If not, have you addressed such statements?
We are considering transplanting the 18 ginkgo trees lining Minato City road. They are included in the “19 trees under consideration for transplantation” mentioned in the “Greenery” section of this official web site.

In addition, we are taking steps to ensure that potentially misleading information is correctly understood through press releases, this Q&A, and other means. We will continue our efforts to ensure greater understanding and support from more people in the future.
Why don’t you provide information or correct false information through “@jingugaienmachi,” the official X account for the Jingu Gaien District Urban Redevelopment Project? Will you issue a warning or take legal action against people who post factually incorrect information?
Although we are disseminating information primarily through the project website at this point in time, we provide notification through our official X account upon issuance of new press releases and other such updates. We are furthermore committed to proactively communicating information including feedback we receive. Please note, if a third party posts information that is not accurate, we will consider taking separate action if we believe legal recourse or other measures are necessary.
On X, it is difficult to tell which accounts are official. What are the official accounts of the project?
The only official X account for the project is【公式】神宮外苑地区まちづくり(@jingugaienmachi).
I saw some posts on X about an information session held in September 2024 with photos of Mitsui Fudosan employees. Was photography allowed at the briefing? Also, was permission for the posts obtained from Mitsui Fudosan or the individuals concerned? Do you plan to issue any warnings or other responses to this kind of post?
At the briefing session on further measures to preserve trees, held on September 28, 2024, photography, video or voice recordings, or posting on social media were prohibited to protect the privacy of all participants. On the same day, Mitsui Fudosan, the representative developer of the project, held a separate Q&A session for the media about the briefing. In their reports, several media outlets used images of Mitsui Fudosan employees taken during the Q&A session, which was approved in advance by Mitsui Fudosan. We will continue to consider necessary measures, including legal action, in the event that photography, video or voice recordings, or posting on social media is conducted without the consent of the developer.

I’m looking forward to the rebirth of the Prince Chichibu Memorial Rugby Stadium and Jingu Stadium. When can we expect an announcement on the design details of each of these stadiums?
The detailed plans for each of the stadiums are still under consideration. Going forward, we will present easily understandable images as the design and other factors to raise the expectations of as many people as possible.
Why was a Tokyo Green Biz poster displayed in the Mitsui Fudosan Jingu Gaien District Urban Redevelopment Project booth at the “Living with Trees” event at Tokyo Midtown Hibiya?
Mitsui Fudosan endorses the goals of the “Tokyo Green Biz” initiative and decided to display the poster because it aligned with the purpose of the event.
Are questions and comments submitted via the question submission form shared in full among all companies involved in the development project? Are they also shared with the Tokyo Metropolitan Government, Shinjuku City, and Minato City?
People submitting questions or comments via the form are asked to confirm several points prior to submission. One of them is as follows.
“This form is managed by Mitsui Fudosan Co., Ltd., the representative developer of the project, solely for the purpose of implementing the project. Please be advised that your questions may be shared with other business entities involved in the project (Meiji Jingu Religious Corporation, Japan Sport Council, Itochu Corporation), government agencies, and consultants for the same purpose.”

Based on the above, we share questions and comments received via the question submission form in full with the other businesses, examine their responses and upload them to the website.
We also share relevant questions with the Tokyo Metropolitan Government, Shinjuku City, and Minato City as necessary.
On the question submission form, it reads “送信後に回答のコピーを印刷することができます (You can print a copy of your answer after you submit),” but I was unable to download a copy after submitting my form. Has the system changed?
The question submission form for the project uses Microsoft Forms. No changes have been made to the form settings since the start of the project and we are not aware of any changes to the system.
If you want to save a copy of your filled-in form, you can also do so by signing in to Microsoft 365 and clicking the “回答を保存する (Save Response)” button on the completion page.

I would like to see a strong rebuttal to the factually incorrect information being spread about the redevelopment project. I do not think there was a forest in the Outer Garden in the first place and removing some of the trees is probably unavoidable. Also, I think many of the news reports about the project are not based on correct information. Are you working with news organizations to ensure reporting is accurate and based on correct information? Do you request corrections to inaccurate news reports?
As the developer, we are actively communicating information to ensure accurate reporting based on correct information provided by the project developers. In the event of a clearly inaccurate report, we make appropriate representations and we will continue to make every effort to communicate accurate information. An explanatory video about the redevelopment project was released on July 1, 2024 and the same information was provided to news organizations. Please click on the following link to see the video.

What plans do you have if dinosaur fossils are uncovered during the project?
In the event that earthenware, stone tools, dinosaur fossils, or other artifacts are discovered through investigations of Buried Cultural Properties or other means, we will respond appropriately in accordance with the Act on the Protection of Cultural Properties and other relevant laws and ordinances.
Has this project, including the construction of high-rise buildings, been explained to the imperial family residing in the Akasaka Estate and has their approval been gained?
While this project is being handled appropriately in accordance with laws and regulations, we are unable to answer questions about specific situations.
Answers to questions concerning the environmental impact of factors such as shade, wind, and noise in this project can be found within this QA.
Shouldn’t you respond to criticism from ICOMOS?
We are unable to answer questions regarding our interactions with specific organizations, but in regard to the Heritage Alert issued by ICOMOS last September, please refer to the release “Developers’ Position on the Heritage Alert” we issued as the project developer.
