ART AQUARIUM MUSEUM is a Japanese-style aquarium inside a Ginza department store, exhibiting goldfish tanks and light-based works. The dark space uses seasonal lighting and music to present the tanks as gallery pieces. Visitors pay at a ninth-floor kiosk, then take the escalator down to the eighth floor to view the exhibits. Seeing everything takes about 20 to 40 minutes, as the space inside the department store is not large.
