Get to know
about theBarrier-free
Hibiya Park
Project

Hibiya Park is a metropolitan park that opened in 1903 as a pioneer of modern Western-styleparks in Japan. It has long been enjoyed by citizens of Tokyo as a precious green oasis and a placeof relaxation in the heart of the city; it is a park integrated with the Imperial Palace and its
surrounding areas.
In July 2021, the Tokyo Metropolitan Government formulated the "Metropolitan Hibiya Park
Renewal and Redevelopment Plan." With this, the TMG will redevelop the park – to be completed
in 2033, marking the 130th anniversary of the opening of the park – by dividing the park into
several areas to be redeveloped in stages.
Under this project, we need to redevelop Hibiya Park into one that is accessible and moreenjoyable for everyone, regardless of age, gender, nationality, and whether or not they have adisability, so we can pass it on to Tokyo residents of the future.
We have compiled the “Barrier-free Hibiya Park Project” as a redevelopment plan toward therealization of this scheme.
In the project plan, we have described how we will treat the existing trees in the park during theredevelopment, together with the content and schedule of redevelopment. We hope that you will
you refer to this document and deepen your understanding of the project as much as possible.
All information in this material is based on information available as of the end of June, FY2023. Updated
data on the contents of the redevelopment and the ways to handle trees in each area will be posted on our
website continuously as the project progresses, by updating the “Barrier-free Hibiya Park Project” andother documents.

5The Basic Concept of the ‘Barrier-free Hibiya Park Project’
Following the basic concept shown below, we will move ahead with this project, thereby having Hibiya Park passed on to Tokyo
citizens of the future.

1

We will redevelop the park into one that everyone can enjoy more while inheriting its
historical and cultural values

We will further refine the appeal of Hibiya Park that has accumulated over the past 120 years, and aim to create a barrier-freespace that is easily accessible for everyone. While maintaining it as the backbone of the greenery in the city center andconveying its culture and history, utilizing its prime location, we will redevelop the park into one in which contributes to thewell-being of every visitor today and Tokyo citizens of the future.

2

We will preserve the greenery of the park

We will preserve the trees appropriately so as to protect the greenery of the park that we have inherited and to ensure thatthe park will continue to be a high-quality green space well into the future.
*For details, please look at p. 12.

3

We will improve accessibility to the park and aim to increase the number of visitors

By installing decks that connect the park to neighboring districts and removing the fences surrounding it, we will redevelop it
into a park where a diverse range of people, including those in a wheelchair or with a stroller, can visit safely, pleasantly andfreely. By enhancing the accessibility to the park, ease of movement around, within, to and from the park, and improving theharmony with its neighboring area, we aim to create a park that people can visit more easily.

The Rationale behind Making the Park Barrier-free
We will grapple with the following tasks so as to redevelop Hibiya Park, which was opened in 1903 as a pioneer of modern Westernstyle parks in Japan, into one that will be easier to use and more enjoyable for everyone, regardless of age, gender, nationality, or
whether or not they have a disability.

Easy to use▶ We will make a park which people can use free from worries and move around inside safely.
• Eliminating differences in levels at facilities such as concert halls and flower gardens.

• Installing flower gardens where even those in a wheelchair can enjoy.
• Adopting universal design playground equipment to be designed together with children.
• Setting up a room equipped with a pot for mixing powdered milk, at which a mother canfeed her baby, and change diapers.
＜ Universal design playground equipment ＞＜ Feeding room ＞＜ Accessible flower garden ＞

Easy access to information▶We will redevelop the park into one where people can get responses at the window and get visitors’ guide free from worries,
and communicate with us in use of the park.
• Use of voice recognition system, tablets, and chatbots.
• Use of guide signs in multiple languages, in easy-to-understand Japanese, and pictograms.
• Utilizing the park as a place for proving the effectiveness of a newly developed information tool.
＜Voice recognition system (conceptual image)＞＜Plain Japanese＞＜Pictograms＞

A park everyone can enjoy▶Using digital technology, we will redevelop the park into one where visitors can enjoy while experiencing its culture and history.
•

Holding events in which people, regardless of whether they have a disability or not, can enjoy together.

•

Enabling those who are unable to visit the park in reality to enjoy strolling inside the park with use of
information and communication technology (ICT).

•Via the QR code or other means, the scenes inside the park at the time of its opening will be shown in
multiple languages and explained with images.

Our Approach to Trees
While protecting the park’s greenery we have inherited, we will preserve the trees based on the concept as
written below, so as to maintain it as a high-quality green space well into the future.

In the process of carrying out the redevelopment work of facilities, we will perverse the trees
・We will carry out the redevelopment work while avoiding trees.

・If the need to move trees arises, we will have them transplanted elsewhere in the park after making a diagnosis.
＜What does a tree diagnosis mean? ＞
The trees’ health condition will be examined by a qualified arborist (tree doctor). The transplantation of trees will be done based on the diagnosis.

To protect trees, we will conserve them appropriately•

If the transplanting of trees is deemed necessary from the viewpoints of ensuring their healthy growth, creating an attractive
landscape, and improving visibility for security and safety of the park visitors, we will transplant them after making a diagnosis.
*To maintain the greenery of the park in good conditions, we will continue the appropriate management ofplanting.

We will give thought to the greenery of Hibiya Park, together with future generations•

The tree diagnosis will be conducted in such a way where parents and children can take part. By doing so, it will give an
opportunity for them to feel the park’s greenery close to them, deepen their understanding and learning of them, and be
prompted into giving a thought to the trees and the park together.

•

The results of tree diagnosis will be made public via our homepage or otherwise.

12

The Basic Sequence of the Project Following the “Metropolitan Hibiya Park Renewal and Redevelopment Plan,” we will firstconsider the outline and work schedule of the project at the stage of drawing the basic designfor each area of the park. We will then carry out the execution design, which considers thedetails of the redevelopment work. After the execution design is finalized, we will begin to
execute the redevelopment work.

The 2nd Flower Garden

Responsible entity: TMG｜Work begins in September 2023

Issues•There are differences in levels between the garden and the pedestrian path around it,
making it not barrier-free. As a result, it has not been fully utilized, except for somespecial events.

The garden will be redeveloped into one whose lawn-covered plaza can be enteredfreely by visitors.
The paths surrounding the plaza will be broadened so that those in a wheelchair orwith a stroller can walk through it safely and reassuringly even on the occasion of a
special event.
Via the QR code or other means, the introduction of facilities and scenes of large-scale
events held in the past will be explained in multiple languages and with images.
Trees will be kept in place as they currently stand, but if the need to move trees arises,
we will have them transplanted elsewhere in the park after making a diagnosis.

Large Fountain and Small Concert Hall Responsible entity: TMG｜Work slated to begin in FY2024

Issues••The Small Concert Hall is located at a more elevated place than its surrounding area
and circled by a fence, leaving it somewhat closed. As such, it is difficult for it to be
used integrally with the adjacent plaza where the fountain is located.
As there are differences in levels, people have to use the stairs or a slope to go to andfrom the concert hall.

Content of redevelopment•••

The Large Fountain will be redeveloped with its present configuration maintained.
As to the small concert hall, the level of its stage and seats are to be lowered toeliminate the differences in levels with that of the ground, while the fence is to be
removed. Through this, the concert hall will be more in harmony with the fountainplaza.
Through the QR code or other means, the small concert hall at the time of the park’s
opening and introduction of the facility will be explained in multiple languages andwith images.
Trees will be kept in place as they currently stand. If the need to move trees arises,
we will have them transplanted elsewhere in the park after making a diagnosis.

Present status (as of end of June 2023)•

The aged concert hall will be rebuilt, while its surroundings will be redeveloped in an integrated
manner with the new hall.
The large concert hall will be renovated in such a way to maintain the sense of openness that only an
outdoor concert hall can provide, while a roof will be installed to cover the stage and front rows of
the audience seats so that a concert can be held even if it rains. Meanwhile, the functions of theroom for performers and the backyard for the hall will be improved, by also taking into consideration
those opinions presented by performing artists and other people concerned.
Through the QR code or other means, the history of the first large concert hall, at the time of thepark’s opening, and an introduction of the facility will be explained in multiple languages and withimages.
The public bidding will be made on the condition that the redevelopment will be carried out in such a
way that trees will be kept in place as they currently stand, in principle; if there arises a need to move
them, they will be transplanted elsewhere in the park after making a diagnosis.

<The original Large Open-Air Concert
Hall Yaon completed in 1923>*The Large Open-Air Concert Hall will be redeveloped by a private-sector business operator, on the basis of
the conditions set forth by the TMG for the public bidding process.

Present status (as of end of June 2023)• The TMG plans to choose a private-sector entity for the work by publicly inviting applications within FY2023 and is now preparing to launch bidding.

Decks

Responsible entity: A private-sector business｜Yurakucho decking installation
starts in FY2025｜Uchisaiwaicho decking installation starts in FY2027

Issues• To gain access to Hibiya Park, it is necessary to cross a wide street, while the park is encircled by fences, making it difficult forpeople not only to gain access to the park but also to feel a sense of connectedness between the park and its surrounding area.

Content of redevelopment• A deck that connects the park to the nearby district is to be installed at two locations. By
improving the peripheral section of the park, including through the removal of the fences, thepark will be integrated with pedestrians’ sidewalks, while the accessibility between the parkand its neighboring area will be enhanced.
• The decks will be equipped with elevators so that those in wheelchairs or with impairments
can visit the park safely and comfortably. Also, by greening the deck, the greenery of thepark will be connected to that in the Uchisaiwaicho 1-chome urban redevelopment district.
*The decks will be installed by a private business operator on the basis of the conditions set forth
by the TMG.
•

<A conceptual image of the peripheralarea of the park in the future>

The conditions set forth by the TMG will be such that the trees will be kept in place, in
principle, but if the need to move trees arises, they will be transplanted elsewhere in the park
after making a diagnosis.

Present status (as of end of June 2023)• Talks are under way between the TMG and the private-sector business to work out the basic design, with the work for the deckon the Yurakucho side (④) to start in FY2025, and that on the Uchisaiwaicho side (⑦) to start in FY2027.

While inheriting the current flower beds, the hedges will be lowered to make the garden more
visible. We will also try to improve the varieties of flowers of each season and continue todeliver the appeal of flowers, while creating flower beds that even those in a wheelchair canenjoy, thus making the garden an attractive place for everyone.
We will also restore the bank of Shinji Pond, which has retained its original appearance at thetime when the park opened, while reproducing the elegant landscape with the use of theremains of the stone walls of Edo Castle to convey the historic attractiveness of the park.
Through the QR code or other means, the introduction of facilities and scenes of Edo Castle
during the closing years of the Edo period will be explained in multiple languages with images.
Trees will be kept in place as they currently stand, but if the need to move them arises, we will
have them transplanted elsewhere in the park after making a diagnosis.

<Mt. Mikasa at the time of the park’s opening>*Owned by the Tokyo Metropolitan Park Association.

We will redevelop this area into one where various kinds of squares and open grounds will converge, creating a space where
people of all ages, including families with little children, can enjoy and relax.
The tennis courts will be redeveloped as a ball game field where not only tennis but also other sports can be played. Mt.
Mikasa – a small hill -- will be kept in place, though partially renovated, so that it can be used in harmony with surrounding
open spaces, while maintaining its continuity with them. We will also develop a new plaza where children can learn andexperience bio-diversity.
Through the QR code or other means, the scene of Mt. Mikasa at the time of the park’s opening and other facilities will be
explained in multiple languages with images.
The Service Center, Exhibition Facility, etc., which are dispersed in the park, will be consolidated into what we tentatively call the“Park Plaza,” as a multi-functional facility.
With the response service made available at the window, utilizing a voice recognition system and so forth, even those withhearing impairments or foreigners can gain access to relevant information without worries.
At Park Plaza (tentatively named), a place will be set up where mothers can feed their babies, change their diapers, or little
children can play indoors even when it rains.
Trees will be kept in place as they currently stand, but if the need to move trees arises, we will have them transplanted elsewherein the park after making a diagnosis.

Present status (as of end of June 2023)•

<Kumogata Pond’s revetment>

By having the revetment of Kumogata Pond and the cobble-stone curb along the garden path
restored to their original state, as seen at the time when the park opened, the historicallandscape centering around the “Crane Fountain” will be recreated.
The azalea hill, which remains since the park’s opening, will be rejuvenated by having the nearby
tall trees trimmed to secure enough sunlight for azaleas, so that they can recover their originalvitality which once attracted many people. Also, by eliminating differences in levels and setting
up slopes, the hill will become accessible to everyone.
Via the QR code or other means, the introduction of relevant facilities and the scene of theazalea hill at the time of the park’s opening will be explained in multiple languages with images.
Trees will be kept in place as they currently stand, but if the need to remove trees arises, we will
have them transplanted elsewhere in the park after making a diagnosis.

Park Redevelopment with the
Involvement of Tokyo Citizens

3Redeveloping the Park, Together with Tokyo Citizens
To realize the redevelopment of Hibiya Park in 10 years time, we will work together with Tokyo citizens.

Having Parents and Children Take Part in the Tree Diagnosis•

Tree diagnosis will be carried out with the participation of parents and children. By doing so, it will provide them with anopportunity of watching how trees would be transplanted, a sense of closeness to the park’s greenery, and help them to deepen
their understanding and learning, thus prompting them to give more thought to the greenery in the park.

Events for People to Experience, in Advance, a Hibiya Park of the Future•

We will hold events to experience, in advance, together with Tokyo citizens, various ways to enjoy a Hibiya Park of the future,including lying in a hammock under a tree or remotely working in the greenery, which will be made possible upon redevelopment.

Guided Tours inside the Park•

We will organize guided tours and so forth so as to give people an opportunity to explore the park and learn about its nature andhistory, thus promoting them into giving thought to a Hibiya Park of the future.
