EDO-MIDORI Registered Green Spaces

Connecting through greenery, protecting and nurturing Tokyo's biodiversity.

• This is a system the Tokyo Metropolitan Government has implemented to register and publicize green spaces where native species are actively planted along with the efforts being made to conserve biodiversity.
• Green spaces that are particularly excellent in terms of habitat and growth environment for native fauna are distinguished and registered as “Excellent Green Spaces.”
• Registered green spaces can use the registration certificate and logo to develop PR about the space as a green space that contributes to the conservation of biodiversity.
• The Tokyo Metropolitan Government holds liaison council meetings where registered companies can exchange information and share issues.
• After registration, the registered spaces can receive technical support and other support to solve problems in maintenance and management.
• Tokyo Metropolitan Government will publicize the efforts of registered green spaces in various situations.

• Introduced in the TV program “TOKYO GOOD! TREASURE MAP” | October 30, 2023

• Japan’s First System Partnership Agreement on the Promotion of Greening Considering Biodiversity Concluded with the Ministry of the Environment | September 11, 2023

Green spaces in the sites of private buildings etc. with a site area of 1,000 m2 or more (the same green spaces designated as applicable in the Tokyo Metropolitan Nature Conservation Ordinance Article 14 Greenery Plans)

(1) A section with planted trees must have an area of 100 m2 or more.
(2) Percentage of areas of native trees: 40% or more for large trees and 10% or more for medium and shrubs
(3) Number of native tree species: Four or more for large trees and three or more for medium and shrubs

The space will be registered as an Excellent Green Space if it meets two or more of the following efforts in addition to the three registration requirements above:
(1) Reduction in the amount used of chemical herbicides, insecticides, etc.
(2) Preservation of feeding grounds and hiding places for insects, birds, etc.
(3) Provision of grasslands and waterfront that serve as habitats for wildlife.
(4) Other consideration given to habitats for wildlife than the three requirements above.

To create an image of native species and ecosystems, traditional colors familiar since the Edo period (Edo purple, wakaba-iro, crimson, rape blossom color, etc.) are used.
Enoki leaves are used for the wings of a wild bird (Japanese white-eye), and enoki nuts (red circles), a favorite food of Japanese white-eyes, are drawn on the tip of the beak to express the connection among wildlife through the planting of native species.
The rounded edges of the Fuji with its clusters of flowers of different sizes represent the harmony (circulation) of the ecosystem. The image of a place where a variety of creatures, from large trees to undergrowth, live and grow.

We ask you to submit a report on the management status of the registered green space once a year.
Then check to see if there have been any significant changes to the shape of the green space and if it continues to meet the registration requirements.
