Located in the center of Futakotamagawa Rise, connecting Futakotamagawa Station to Futakotamagawa Park, the II-a district is an "eco-museum" landscape concept that creates value for the local environment. The 6,000-square-meter roof garden spreading out above the low-rise building incorporates not only the Tama River, but also the rich nature of the surrounding area, including the Musashino Plateau, Kokubunji Cliff Line, and Todoroki Valley, and actively reflects the varied topography to create the foundation for a biological network connecting ecosystems.
