Initiatives at Futako Tamagawa Rise
Futako Tamagawa Rise is a complex (total development area approx. 11.2 ha) consisting of commercial facilities, offices and high-rise residential buildings adjacent to Futako Tamagawa Station (Setagaya-ku, Tokyo) on Tokyu Den-en-toshi Line and Oimachi Line. The following initiatives are being undertaken in the Futako Tamagawa Rise II-a block. These initiatives have earned the building an AAA rating from the JHEP Certification.
1) Urban and community development with the natural environment
The site is located on the north side of the Tama River, and is surrounded by the Musashino Plateau, the Kokubunji Cliff Line, and Todoroki Valley. In order to restore and preserve the natural environment from before development, the landscape plan is based on the idea of an "ecomuseum" that aims to connect the life in the area and create a natural environment, and a rooftop garden with a green space ratio of over 40% of the site is arranged. In particular, aiming to "create a space rooted in the community", a planting plan is being made using local seeds and seedlings from the Tama River basin that incorporate wild plants and trees found in the surrounding area, creating a space that connects the ecosystem of the Tama River adjacent to the site.
2) Learning from the local natural environment
The expansive rooftop garden, covering approximately 6,000 square meters, includes an area that recreates the Tama River bank, as well as an area dedicated to the conservation of endangered Aster kantoensis, a plant that is representative of the Tama River bank. A biotope has also been established with the aim of restoring the Tama River ecosystem, and hundreds of species, including Japanese killifish, loaches, Japanese minnows, and turtles, have been established, recreating the river's unique natural environment. Many birds and dragonflies also visit the garden. The rooftop garden not only serves to preserve the local ecosystem, but also serves as a place of relaxation for local residents and facility users, and a place of learning where participants can experience the local natural environment and ecosystem through various events.

Development of the biodiversity model district park "Miyamae Utsukushinomori Park"
We have been developing the "the Tama Den-en-toshi area" area along Tokyu Den-en-toshi Line Line since 1959. The "Inukura District Land Readjustment Project," completed in 2006, is located in Kawasaki City, approximately 1 km from the north exit of Tama-Plaza Station, and development of this 18-hectare area was carried out with "consideration for the natural environment" as one of the basic policies.
The area is part of the source of the Yagami River, which is part of the Tsurumi River system, and the rice fields, well-maintained by the landowners, are home to fireflies and loaches. Based on this, the preservation of habitats for rare species was prioritized, and in consultation with local residents and conservation groups, and with the cooperation of the local elementary school, Miyamae Utsukushinomori Park was developed as a model district park for Biodiversity. The park was transferred to Miyamae Ward, Kawasaki City after the land readjustment project was completed.
Greening at Tokyu Hospital
Tokyu Hospital, located above Ookayama Station on Tokyu Meguro Line and Oimachi Line *1, has planted large amounts of greenery on its walls and rooftop in an effort to blend in with the surrounding environment. In particular, wires *2 have been stretched across the south and west walls, with 4,200 ivy plants of seven varieties wrapped around them. This greening reduces direct sunlight and cuts down on electricity consumption in the interior space. It also reduces heat dissipation from the building, helping to prevent global warming. As a hospital that contributes to the local community, we will continue to cultivate greenery with an eye to the next 10 years and beyond.
- *1This is Japan's first "station hospital" directly connected to a station.
- *2The spacing between the wires is determined based on predicted ivy growth 10 years from now.
