Kaiyukan is one of Japan’s most spectacular aquariums, world-renowned for its innovative presentation. Kaiyukan shows the aquatic animals of the Pacific Rim at their most vibrant and dynamic, by recreating the natural environment of their habitats. At Kaiyukan there are over 15 large tanks, each recreating a specific region of the Pacific Rim, taking visitors on a virtual tour of the Pacific Ocean. The tanks include, “Japan Forest,” which recreates a sunlit, beautiful Japanese forest; the icy, snow-clad “Antarctica;” and the centerpiece of the aquarium, “Pacific Ocean,” a 9 m deep, 34 m long tank containing 5,400 tons of water, serving as the home of whale sharks, the largest fish species in the world.
