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. The exterior facade of aluminum and glass reflects the jumbled nature of the surrounding streetscape.
