The main focal point of the Ocean Expo Park is this spectacular aquarium, the second largest in the world after Atlanta's (in the United States). It shows the life of the Kuroshio ocean current that bathes the archipelago. A 60cm-thick glass screen around the central pool, which contains 7 500m3 of water, enables you to see the fabulous and graceful ballet of the whale sharks, manta rays and numerous other fish. Dolphin shows are also scheduled at regular times.
