Located on the shore of Tokyo Bay in Kasai Rinkai Park, this public facility is Tokyo's largest -- yet cheapest -- aquarium, with tanks displaying marine life of Tokyo Bay and beyond, including the Pacific, Indian, and Atlantic oceans. Hammerhead sharks, bluefin tuna, the giant ocean sunfish, penguins, puffins, a touch tide pool, and a 3-D movie are some of the highlights. The park also contains a beach, a small Japanese garden, a bird sanctuary, and what is claimed to be Japan's largest Ferris wheel (fare: ¥700), making it a good family outing.
