Marinepia Nihonkai - Niigata City Aquarium

See, feel, learn! The largest aquarium on the Sea of Japan

Located in an open coastal area that is constantly refreshed by sea breezes, and with approximately 600 species and 30,000 specimens of sea life on display, Marinepia Nihonkai is one of the most prominent aquariums on the Sea of Japan coast. 

The most popular attraction is the dolphin show, where a few lucky spectators are chosen from the audience to touch the dolphins, give them signals and view them at close range. The Marine Safari area feeding time for sea lions is also a crowd pleaser. The feeding spot is very close to the audience seating, meaning that visitors can really get a sense of the size of the sea lions. The marine tunnel runs along the bottom of the large Sea of Japan tank that features approximately 40 species. As you walk along this tunnel you can enjoy the feeling of walking through the ocean.

There are various areas in and around all the tanks where visitors have the opportunity to touch and feel things for themselves, and there are many exhibits and attractions for children, including quizzes and flip book cartoons.
