Officially it’s the “Eco Edo Nihonbashi Art Aquarium”. Started in 2011 to celebrate the 100th anniversary of the bridge at Nihonbashi, the event has gathered quite a following as a summer event in Tokyo and is now in its 8th year.
The exhibition features ornamental goldfish in various ornate bowls, tanks and ponds with colorful lighting and effects. Even on weekdays, it can be quite crowded. In general, it’s more a place to take interesting snaps rather than peacefully contemplate the art.
From 7pm the venue transforms into a drinking spot (better for adults than kids) with DJs, light shows, special cocktails, premium sake in a “night aquarium”.
