Oga Aquarium GAO perches on the cliffs of the Oga Peninsula with a panoramic window overlooking the Sea of Japan, showcasing the rich marine life of the Akita coast alongside polar bears, Humboldt penguins and walruses. The open-ocean tank simulates the rough Sea of Japan, and the naturalistic polar bear habitat allows underwater viewing through a glass tunnel.
