Oga Aquarium GAO features creatures from the Oga Sea, with additional exhibits displaying creatures of Japan and abroad in their natural environment. When you enter, you will be greeted by the “Oga Large Sea Tank”. It is an impressive tank that reproduces the sea of Oga from spring to summer and displays about 2,000 creatures representing 40 species. On the second floor, is the must-see exhibition area specializing in fish from Akita Prefecture, “Hatahata.” Designated as the official fish of Akita Prefecture, you can learn more about the Hatahata that has long been involved in Akita's food culture as a preserved food. Feeding time for the polar bears, penguins, and seals is typically announced and it is recommended that you go to see how they eat.

 In addition, the restaurant on the first floor allows you to enjoy dishes made with seasonal ingredients from Oga and Akita while looking out at the Oga Sea. It is an aquarium like no other, which takes advantage of the oceanside location of the Oga Peninsula. It is a perfect spot for everyone, especially family, friends, and couples.
