Art Aquarium Museum GINZA

Immersive entertainment art that stages goldfish-swimming tank works with light, scent, and sound.

Art Aquarium expresses the culture of goldfish appreciation—a tradition since the Edo period—as modern art. The beauty of tank works, spatial staging, and the fantastical space created by goldfish of various beauty unfold.

Since its birth in Tokyo in 2007, it has been held as a limited-time event nationwide, and summer events in Tokyo have become established and loved.

In August 2020, the first permanent museum opened in Nihonbashi, Tokyo (Chuo-ku), and then relocated to Ginza, Tokyo (Chuo-ku, Ginza Mitsukoshi New Building 8F) in May 2022, where it currently operates. As of October 2025, it boasts a cumulative audience of 13 million people, making it an entertainment museum IP.
