Spiral, also known as the Wacoal Art Center, is a multi-use building in Aoyama, Tokyo, Japan, that was designed by architect Fumihiko Maki.

Spiral includes exhibition spaces, a multipurpose hall, cafes, restaurants and bars, beauty salons, and select shops.

The defining feature of the building is a seemingly-floating spiral ramp (15 m 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.

Spiral is a nexus of cultural life in Aoyama, presenting music, art, film, fashion and theater events.
