Within the Tempozan Harbor Village at the center of the Bay Area you will find, housed in a structure of remarkable design, the Osaka Aquarium "Kaiyukan," one of the largest aquariums in the world. Consisting of 15 water tanks centered on a single huge tank holding 5,400 tons of water, it is home to 620 species and 30,000 marine animals from the Pacific Rim―everything from strangely delightful jellyfish, to playfully chortling sea otters, to dolphins, penguins, and even a pair of majestic giant whale sharks, the largest fish on earth. This is like no other aquarium anywhere, and it's a magnetic attraction for both children and adults. Come see and be amazed.
