Kasai Waterfront Aquarium

The aquarium is located in Kasai Rinkai Park, a vast park of approximately 80 hectares facing Tokyo Bay.
It holds the record for the largest number of annual visitors to an aquarium in Japan and is the most visited aquarium in eastern Japan.

The building is a glass dome about 30 meters above the ground at the center of the pond.
The entrance is directly under the dome, and the exhibition space extends underground.
The building was designed by Yoshio Taniguchi, who also designed GINZA SIX and other buildings.

The museum houses approximately 650 species of organisms in 47 tanks, including tuna migrating in a large doughnut-shaped tank.
