This aquarium is in an ideal location overlooking the Sea of Japan. There are many living things here including polar bears and Hatahata (sailfin sandfish), the fish of Akita Prefecture.
The spectacular 800-ton tank, the largest at GAO, recreates the period from spring to summer off the coast of Oga. Looking up at the water tank in the tunnel underneath is truly like being at the bottom of the sea. There is also a Hatahata specialty area, where you can learn about the unknown ecology of Hatahata, the food culture rooted in Akita, and the history of fishing.
The polar bears and spotted seals are popular. They captivate the people who watch them with their charming appearances as they play, eat, and swim. Two types of penguins are raised here, and baby penguins appear in the display area every year.
There is also a restaurant where you can dine while gazing at the sea off Oga. In the shop, there are Oga Aquarium original cute stuffed animals as well as the aquarium’s original products that are perfect as souvenirs.
