Spiral is a building by architect Fumihiko Maki in Aoyama, Tokyo, Japan. It was commissioned by lingerie company Wacoal and was completed in 1985. It is a multi-use building, with gallery space, multipurpose hall, cafe, restaurant and bar, salon, and shops. The defining feature of the building is a seemingly floating spiral ramp (15m in diameter) that encircles the rear gallery space and climbs to the second floor.
