The role of the forest
The existence of the Otemachi forest is not just to create a shaded space of natural beauty. Aside from these benefits, the project was formed from the desire to enhance the underground space of the building, transforming it into a bright space rich in natural light, alleviating the building’s heat and contributing to the prevention of flood damage.
A strong forest with lush greenery and large trees, the forest is now home to 13 species of birds, 15 species of grasshoppers, and 34 species of butterflies, promoting biodiversity in the heart of the city. Several globally threatened (Red List) tree species have also been identified.
