This aquarium consists of the Sunfish Hall, with sunfish that can grow to a length of three meters; the Ancient Aquarium, where fish and fossils are exhibited under themes of ancient times; and other areas. In the Migration Fish Tank, where sharks and yellowtail swim freely, visitors can watch a fish feeding demonstration by an ama (female diver). A hands-on event, where participants can touch the back of a penguin, is also offered. (Prior reservation is required.)
