Osaka Aquarium Kaiyukan

Osaka Aquarium Kaiyukan is one of the world's largest aquariums, built around a massive central tank representing the Pacific Ocean that houses whale sharks, the world's largest fish, alongside manta rays and thousands of other marine species. The spiral walkthrough design takes visitors from the peaks of Mount Rainier down through 14 ecological zones to the depths of the Pacific, passing themed tanks representing ecosystems from Antarctica to the Amazon River. Since opening in 1990 on the Osaka Bay waterfront, Kaiyukan has become one of Japan's most beloved family destinations.
