Greening at Otemachi Forest (Otemachi Tower) and Tokyo Square Garden

We created approximately 3,600m² of forested space, called the Otemachi Forest, at Otemachi Tower in Chiyoda Ward, Tokyo. This forest
was created to mimic a real forest, reproduced by gathering natural trees from the mountains in the Kanto region, which shares the same
climate as the Otemachi area. We were able to create a foundation for these trees to take root and grow. In this project, we adopted thepre-forest method by examining plant growth and using appropriate management methods over the span of approximately three years fora forest of about 1,300m² in Kimitsu City, Chiba Prefecture. After our preparations were complete, we transferred the plant life to the mainsite in Otemachi. Otemachi Forest not only helps mitigate the heat island phenomenon in the city center through tree transpiration and soil
water retention, but also forms an ecological network that connects with the green areas of the Imperial Palace and provides a comfortable
habitat for living creatures.
Tokyo Square Garden is a new environmentally friendly building complex in Tokyo's Chuo Ward. Here, we have implemented solar power
generation, installed high-efficiency heat equipment, and other eco-friendly facilities. This equipment,
installed at Kyobashi Hill, a multilayered green space spanning approximately 3,000m², creates a coolspot in the city center that helps counteract the heat island effect.
Otemachi Forest was the recipient of the 35th Green City Award (Minister of Land, Infrastructure
and Transport Award). Tokyo Square Garden was the recipient of the Minister of Land, Infrastructure
and Transport Award for the 14th Competition for Specialized Greening Technology for Rooftops,
Wall Facings and New Green Spaces. Both buildings have been certified as an Urban Oasis by SEGES(Social and Environmental Green Evaluation System).
