Green Urban Development
for the Next 100 Years
Taking every available opportunity to create and preserve greenery, the Tokyo
Metropolitan Government (TMG) has advanced a range of efforts to date, with theaim to enhance the quantity and quality of greenery throughout our city.
Meanwhile, in recent years, we have seen a shift in trends related to green spaces,
including the functions expected of cities and people’s values. For example,
greenery is being used to help address social issues, including in climate
adaptation measures, and the need for open green spaces has increased as a resultof the COVID-19 pandemic. In December 2022, the Kunming-Montreal Global
Biodiversity Framework was adopted during COP15, establishing a set of global
goals aimed at realizing a “nature-positive” world. Harmony between the naturalenvironment and urban functions is valued more than ever before across theglobe, with overseas cities engaged in promoting green infrastructure and otherinitiatives.
Against this backdrop, the TMG launched “Tokyo Green Biz” in July 2023. This
new green project looks 100 years into the future and aims to further enhance thevalue of our city’s greenery, which brings a sense of ease and calm to daily life,
and to pass down our green spaces to future generations with the cooperation ofTokyo residents.
In August of the same year, we established an advisory board to gain the input ofexperts from various fields to assist in the promotion of Tokyo Green Biz. We
have also taken efforts to gather an even broader range of opinions, such as
through conducting surveys targeting children, youth, and foreign nationals.
While incorporating these opinions and suggestions, we will strengthen existing
initiatives and formulate new measures, focusing on the three perspectives of“protecting,” “nurturing,” and “utilizing” Tokyo’s greenery.
By furthering our vision of green urban development for the next 100 years
together with the citizens of Tokyo and other partners, we will expand our circle
of initiatives and transform Tokyo into a sustainable city that exists in harmony
with nature.

The diverse functionsof greeneryGreenery offers diverse functionality, such as creating spaces for interaction,
mitigating global warming, enhancing disaster resilience, and provides us with avariety of blessings.

Primary functions of greenery
Formation of an enriching living environment

Formation of places to interact

Greenery provides different colorful landscapes throughout theseasons, enriching and comforting us, reducing stress, andimproving comfort.

The pleasurable spaces created by greenery serve as places tointeract for a variety of activities, sports, and recreation in thecommunity, nurturing our healthy minds and bodies.

Prevention of global warming

Securing habitats for wildlife(tCO₂ conversion/ha)

Greenery absorbs carbon
dioxide and contributes
to the prevention of
global warming. The
planting of young trees iseffective for use as woodmaterial and absorbing alarge quantity of carbon
dioxide.

Formation of scenery, views, history, arts, andcultureGreen areas serve to prevent the spread of fires and as
evacuation sites during disasters. Forests also give rise to richwater resources, and play an important role in protecting fromdisasters by limiting sediment runoff.

Greenery is the foundation of scenery and scenic views. In
combination with cultural heritage resources, greenery
contributes to the promotion of bustle, vitality, and tourism inthe community.

Member Yukihiro
Shimatani[Green Infrastructure]●●

Farmland is being sold in parcels because of the enormous burden of inheritance taxes on farmers.
The scope of the inheritance tax deferment system should be expanded to include woodlands.

●

If people in the city center are not proactively provided with chances to interact with nature, then green
spaces and the city itself cannot be maintained.
● Example: Visualize information and promote ownership, such as with the New York Tree Map.

●●

Seedlings that take local genetic diversity into account should be cultivated when redevelopment occurs.
We should establish an environmental education hub and train environmental experts.

<Adopting Green Infrastructure>●

Greenery should be seen as a form of infrastructure, and it is important to properly evaluate the function
thereof.
● We should develop a green infrastructure model in the Zenpukuji River basin (rain gardens, swales)<Financial industry trends related to the Natural Capital domain>
Member Mari
Yoshitaka[ESG Investment]●

The risks to corporate activity and financial institutions from changes in Natural Capital is rising. The
TNFD and others has been established to build a system for disclosure thereof.
● Investment in the Natural Capital domain via domestic and international financial institutions is growing
active.

<Tokyo Forestry>Member Hideo Sakai<Forestry>Member Akio
Shimomura<Parks>●How can we raise the value of forests as a resource to make forestry a growth industry?
The quality, health, and growth of existing trees is improved by repeated thinning.
● The training and securing of personnel, such as through the Tokyo Training Forest (training for logging
and transport experts), is essential to make forestry appealing.

<Toward Coexistence Between People and Greenery>●

The greenery that speaks of the characteristics and history of each area and place should be considered acommunity resource.
● Appropriate human intervention is necessary to utilize and manage greenery.

<Tokyo Greenery 100 Years in the Future>Member Midori
Watanabe[Generation Z]

Member Hikaru
Kobayashi[Environment]●

I wish to propose a corridor that connects green spaces because greenery is dispersed throughout the cityand difficult to access. However, this would incur issues such as maintenance costs and personnel
shortages.
● Tokyo is a place where people and ideas are concentrated. Young people wish for a community that
ensures their well-being.

<Reconsidering environmental policy on greenery and expectations toward city initiatives>●

We should set a standard for greenery for the Reiwa era and aim to create greenery with biodiversity and arich ecosystem.
● If we are unable to meet the greenery goals for each mesh, then why not attract the investment andparticipation of developers by achieving greenery goals in other places?

Other Expert Opinions● Can residential tree areas be converted to public land or made tax exempt?
● It is important to preserve agricultural land by having the government purchase it proactively.
● We should establish an environmental education hub and train environmental experts.
● Training and securing personnel is important for developing forestry.
● It is difficult to protect greenery by leaving it in its natural state. Both staff and funding is required.
● We should make information visible and promote city resident participation.
● Tokyo forests are mostly secondary, not primary, so high quality management is necessary.
● We should communicate more about the appropriate management of greenery.
● We should adopt green infrastructure.
● The environment is now the source of profits and corporate attitudes have changed.
● We must train personnel able to manage greenery.
● The concept of partnerships to promote greenery with the community and companies is important.

ProtectProtecting Greenery Rooted in theCommunity (e.g., Estate Woodlands)
Conservation of greenery on private land,such as estate woodlands

Overview
Estate woodlands are recognized in 800 locations throughout Tokyo, covering
more than 200 hectares in total. While many residential tree areas are being
designated as conservation trees and forests by the local municipality, or as
citizen green spaces and special green space conservation areas under the
Urban Green Space Law, many others are disappearing due to inheritance andother causes.

Main initiatives▶ Special green space conservation area program
53 green spaces in Tokyo, approximately
321 hectares, are designated as Special
Green Space Conservation Areas under
the Urban Green Space Law for forming
beneficial natural environments.

to enter into contracts with private landowners to establish and manage citizen
green spaces under the Urban GreenSpace Law. 56 of these locations havebeen established in the city.

(As of March 2022)(*) Contract term is 5 years or more
Merits include reduction of the management burden of theland owner

Future Initiatives
In order to preserve valuable private greenery, such as estate woodlands, wemust respond quickly when land is inherited, enable the concurrent purchaseof non-forested land, such as residential land, and lessen the resistance toparting with ancestral land.
Accordingly, initiatives to strengthen government purchasing of land will beapplied to the preservation of 50 hectares of nearby woodland property, suchas estate woodlands, in 100 locations by 2043.

▶ Strengthen support for purchases during inheritance
To enable responding quickly when land is inherited, new support will be
provided using various funding to enable municipalities to purchaseresidential tree property in Special Green Space Conservation Areas.

▶ Park development using connected woodland
The development of parklands will be promoted through the purchase ofwoodland and residential properties together when estate woodlands arepresent on the property.
Stronger support for municipalities by expanding park development projects with greenery<Example>
Property combined with woodland

Woodland* Some criteria must be met, such as
the scale of the woodland.

▶ Historic preservation initiatives for residential tree property
Efforts will be made to preserve owner’s names in the names of Special GreenSpace Conservation Areas (such as “Former <Name> Special Green SpaceConservation Area”), or install signage describing the history of the estate
woodlands, with consideration for the owner’s preferences.

ProtectProtecting Greenery Rooted in theCommunity (e.g., Estate Woodlands)

Initiatives to preserve agricultural land
Overview
A total of 871 hectares of urbanization promotion areas and 319 hectares ofurbanization control areas have disappeared over the past ten years in Tokyo,
highlighting a need for initiatives to preserve valuable urban agricultural land,such as productive green land.

Main initiatives

Changes in agriculturalland area▶ Preservation of productive green land
Funding is provided to municipalities when
they purchase productive green land for the
purpose of agriculture. Furthermore, subsidies
are also provided to help cover costs incurred
when municipalities preserve greenery on
productive green land by establishing parksand other measures, when agriculturalactivities on the urban planning park etc.
cannot be expected to continue.

Area(ha)Inside urbanization promotion area
Outside urbanization promotion
area▶ Specified productive green land
Agricultural land in urbanization promotion areas that is designated as
productive green land is subject to tax relief, but the designation also obligatescultivation of the land for a period of 30 years, after which the special tax
measure no longer applies.
Because much of the productive green land in the city was designated in 1992,
Tokyo, in cooperation with municipalities, agriculture commissions, the Tokyo
Agriculture Commission, and agriculture cooperatives, has been encouraging
farmers to transition their property to a Specified Productive Green Land
designation under which the special tax measure can be extended for 10 years.
As a result, approximately 94% of productive green land is now designated asSpecified Productive Green Land.

Future Initiatives▶ Promoting matching and long term farmland leasing
Expand the support for owners of agricultural land who lease it for long
periods to include agricultural promotion areas in addition to productive green
land, while also establishing a liaison desk to provide matching services for
productive green land over wider areas than individual municipalities.

We are engaged in outreach through symposiums and workshops andexchanges of opinions with stakeholders to promote the preservation anddevelopment of agricultural scenery under the program to designate
Agricultural Scenic Development Districts.
[Agricultural Scenic Development District program]This is an initiative to designate districts where
agricultural land and estate woodlands are relatively
consolidated in order to combine the distributed
farmland into urban planning parks, conserve thefarmland in the form of open spaces, and pass on
agricultural scenery to future generations.

Introducing a New Scheme to Protect
Protect Trees
Overview
Establish a “Tree Bank” as a new system to preserve trees by taking in andstoring transplanted trees for use in new parks. The trees will be passed down
to future generations by transplanting them to new locations after being grown
and cared for in parks.

Future Initiatives
Utilize the trees for updating functionality of city parks, such as removing
barriers, preparing maritime parks, and rebuilding city housing, and consider
utilizing trees from the Tree Bank in projects to which various city
development policies apply.
Note that, when necessary, the advice of arborists and other experts will beconsidered when transplanting trees.

Protect

Promoting a Sustainable Forest Cycle

Overview
Approximately 40% of the total area of Tokyo is forested. Forest exercise
numerous functions. In addition to providing lumber, they also generate
abundant water sources and protect city residents from disasters, such as bylimiting sediment runoff.
It is important to establish a cycle for forests involving logging, utilization,
planting, and nursery cultivation in order to maintain Tokyo’s abundant forestsand make them sustainable.

In order to pass forests on to future generations as a shared asset of the citizens,
Tokyo is working to establish a sustainable forest cycle and strengthen the
management of forestry.
By establishing a stable supply of Tama wood and expanding the use thereof,
involving the harvesting and transport of Sugi and Hinoki evergreens that havereached maturity via Primary Logging, the volume of Tama wood being used
has been steadily increasing, comprising approximately 80% of wood harvested
via City projects.

Forests and Decarbonization

ColumnIn recent years, the area of Japan’s forests has remained more-or-less stable, thegrowing stock, or the total volume of tree trunks comprising the forests, continues
to increase.
On the other hand, there is a tendency for forests’ greenhouse gas absorption
volume to decrease with the aging of planted forests.
To ensure forests’ absorption, we are promoting a forestry cycle of “fell, use, plant,
grow.” Additionally, revisions were made to the J-Credit Scheme in August 2022*
to facilitate the steady creation of young forests.

This is carried out primarily for deciduous trees to help the overall tree
develop its structure.
Light pruning is carried out to adjust the concentration of sprouting
branches, organize the canopy, prevent the trees from falling down
during strong winds due to typhoons, and to prevent disease andinsect infestation.
