A little bit outside of the city center of Tōkyō, Japan, close to the harbour and Disneyland you can find the Tōkyō Sealife Aquarium. You can see 600 species from the Pacific, Atlantic, Indian Ocean and from Arctic and Antarctic.
Most impressive is a 2200 tons weighing tank in the shape of a donut which contains a swarm of bluefin tuna fishes circling around. You can also see some penguins and learn more about the maritime life in the Tōkyō bay.
