Oga Aquarium GAO is a scenic aquarium situated along the coastline of the Oga Peninsula in Akita Prefecture. Leveraging its prime location facing the Sea of Japan, the facility showcases fish species native to the nearby waters as well as iconic animals like polar bears. It serves as a vital center for learning about marine ecosystems and is deeply rooted in the local community.
The facility has a long-standing history as the former Akita Prefectural Oga Aquarium. Established in 1967, the original facility gained fame for its successful breeding of the Panama eyed caiman in 1972, a first in Japan. After a period of closure for renovation, the facility reopened in July 2004 under its current name, "Oga Aquarium GAO." Today, it is managed and operated under a designated administrator system by Oga Aquarium Co., Ltd.

The exhibition area is divided into several distinct zones. Visitors can enjoy viewing polar bears, penguins, and a wide variety of creatures native to the waters surrounding Akita Prefecture. The facility features diverse tank configurations designed to showcase the unique characteristics of each species.
Standard operating hours are from 9:00 to 17:00 (last entry at 16:00).

We highly recommend checking the official website before your visit. Additionally, certain exhibits, such as the polar bear display, may be temporarily unavailable due to maintenance or biological shifts, so please check for the latest updates.

Through its diverse displays, the aquarium offers deep insights into marine ecosystems. The facility is fully equipped to support a comfortable stay, featuring an on-site museum shop and a restaurant where you can enjoy meals while immersed in the aquatic atmosphere.
The Oga Peninsula area is home to various hot spring resorts, such as Oga Onsen, and several cultural landmarks. Oga Aquarium GAO serves as an excellent starting point for a sightseeing route exploring the natural and cultural beauty of the peninsula.
