“Ohashi Sato no Mori”
Ohashi Sato no Mori is a natural regeneration green space developed on the roof of the tunnel ventilation center located inside Ohashi Junction and modeled the original scenery around the Meguro River.
It is thought that there were a valley and terraces around the Meguro River in the early Showa era; marshy areas that included paddy fields lay in the valley, grasslands of Japanese torreya and other plants stretched out on the terraces, sloped forest and springs were found on the terrace cliffs, and the murmuring of streams was heard.
There is a slope for ventilation on the tunnel ventilation center and nature of the original scenery around the Meguro River is reproduced utilizing the slope.

It grows only 30 to 50 centimeters a year and takes long to grow, but it is expected cover the walls with green over the years.
What is An Ecological Network?
An ecological network is a concept and practical activity to restore a deteriorated ecosystem and conserve biodiversity by interconnecting the growth and habitat of divided species.
Ohashi Sato no Mori connects the Yoyogi Park and the surrounding greenery with the Meguro River as the axis. It plays a role as one of the bases of the ecological network.

- SEGES (Social and Environmental Green Evaluation System) is a certification system that evaluates the excellence of green lands created by corporate organizations and their relevant daily activities and recognizes that they are excellent green land that contributes to the environment and society and are maintained well.
Registration in EDO-MIDORI Registration Green Space
On August 21, 2019, it was registered in the "EDO-MIDORI Registration Green Space (*)", a native species planting system in Tokyo. Only native species of trees are planted and excessive cutting is avoided to keep them close to their natural state for six years after maintenance. These efforts were praised to protect the ecosystem and natural environment by not using pesticides.
- "EDO-MIDORI Registration Green Space (*)": A system in which the Tokyo Metropolitan Government registers and announces green spaces with native species actively planted and work to conserve biodiversity.
Obtained JHEP Certification "AAA" (highest rank)
Ohashi Sato no Mori acquired the highest rank "AAA" in "JHEP Certification" on September 21, 2016. Using the original scenery around the Meguro River area as a model, we have restored a high-quality natural area resembled to the nature inherent to the area by limiting the types of seedlings to native species.
Native species of trees and grasslands are planted and excessive cutting is avoided to keep them close to their natural state from the time of maintenance. And we have thoroughly maintained and managed the extermination of alien species in order to raise native species. These efforts were evaluated, and it became the highest rank "AAA" certification in JHEP.
- The JHEP certification (Japan Habitat Evaluation and Certification Program) is a quantitative evaluation of the efforts of companies by comparing the degree of contribution and impact on biodiversity before and after the project. In Japan, it is evaluated and certified by the Japan Ecosystem Association. The Japanese version of HEP developed by the US Department of the Interior as a method for quantitatively evaluating the environment in the 1970s and 1980s.
