This aquarium is considered the best not only in Okinawa, but in the whole Japan, and even more surprisingly, it has been ranked as one of the top ten aquariums in the worldwide surveys done. It was established following the end of the 1975 World Fair (also referred to as the World Ocean Expo). The buildings as well as pavilions were replaced by the Ocean Expo Park (Okinawa National Government Park).
The visitors must visit the Kuroshio Tank, the largest tank in the world when built, to see the huge Whale Sharks, and the Manta Rays of which some were born at this museum! It is recommended for families as children would definitely love the aquarium for its uniqueness, beauty and friendliness!
