The iconic glass dome was designed by architect Yoshio Taniguchi, who also designed the Museum of Modern Art expansion in New York.
The aquarium's bluefin tuna display was the first in the world to successfully maintain a school of the fish in a circular tank for long-term study.
The facility manages one of the largest penguin colonies in Japan, including Magellanic, Humboldt, Gentoo, and Rockhopper penguins.
The aquarium is located on reclaimed land in Tokyo Bay, providing direct views of the Boso Peninsula on clear days.
The central tank uses a unique current-generation system to keep the tuna swimming continuously in a circular pattern to prevent them from colliding with the walls.
Tokyo Sea Life Park is a public aquarium characterized by a massive 30.7-meter-high glass dome, which serves as the facility's iconic entrance. It is situated within Kasai Rinkai Park in Edogawa, Tokyo, directly overlooking Tokyo Bay. The aquarium features a central 2,200-ton donut-shaped water tank housing a school of bluefin tuna, a species notoriously difficult to keep in captivity. The exhibits are organized by geographic region, displaying marine life from the Seven Seas, including the Indian, Pacific, Atlantic, and Arctic oceans. It hosts a specialized Penguin Ecology exhibit that is one of the largest in Japan, showcasing four different species. The aquarium functions as part of a larger ecological research initiative focused on marine conservation and public education. The site utilizes a circular flow design to guide visitors through different ocean environments. The facility is managed by the Tokyo Zoological Park Society.

Allocate extra time to explore the surrounding Kasai Rinkai Park, which includes a bird sanctuary and a large observation ferris wheel.
Check the daily event board upon entry for scheduled keeper talks and feeding demonstrations.
Avoid arriving mid-day on weekends, as wait times to enter the main dome can be significant due to high visitor volume.
Closed on Wednesdays; if a public holiday falls on a Wednesday, it is closed the following day. Closed annually during the year-end and New Year holidays.
Refrain from using flash photography near the tanks to avoid distressing the fish.
