Ginza has been a prestigious commercial district in Tokyo since the Meiji period. This building is located in the center of this district, at the intersection of Namiki and Miyuki St. it was planned to accommodate first class fashion tenants and restaurants. Since the new “Ginza Design Guideline” in 1998 allows buildings to be 50m high, we tried to design a high quality tower with the concept of a “Crystal Tower”. The building’s appearance attracts people differently between  day and night.
