What to see
- Bluefin tuna: a 2,200 m³ doughnut-shaped tank where schools of Pacific bluefin tuna swim around you. The aquarium was the first in the world to display a school of them, and in 1999 the first to have them spawn in an aquarium.
- Penguins: more than 100 penguins in one of Japan’s largest penguin exhibits.
- Oceans of the World: sea life from around the globe, from coral reefs to the Arctic and Antarctic.
- Tokyo’s ocean: creatures from Tokyo Bay out to the Ogasawara Islands.
- The glass dome: the entrance dome overlooking the sea is a landmark in itself.
In total the aquarium shows more than 500 species. It opened on October 10, 1989, and grew out of the “fish viewing room” that opened at Ueno Zoo in 1882.
