Mt. Atago is a development area and a small hill 26m above sea level. It is a precious place both culturally and historically with the NHK Museum of broadcasting located there and temples sprinkled throughout such as the Atago temple of the Tokugawa family and Seisho temple. Sandwiched between the super high rise Mori Tower and the Forest tower complex sits the architecture of Seisho temple.The two towers create a pair of continuous urban landscapes through a form that narrows as it approaches the sky. The pair of towers also serves as a gate that forms the sacred boundary of the precincts of Seishō-ji Temple. The form of the pair of towers narrowing toward the sky was also inspired by the buds of lotus flowers blooming in the Pure Land. The design of the top of the tower which glides into the sky and the surface of the wall are set back to give an impression that the tower is going into the sky.
