With the world's largest water tank
Umitamago Aquarium

Aquarium Umitamago at Oita Marine Palace is a large aquarium famous for its 1,250-ton water tank, which is the largest in the world. As you walk along the large fish tank, you'll feel like you're underwater, surrounded by fish and other marine animals!

Umitamago’s signature star! walrus

Umitamago's star walruses are smart friends who get along well with their trainers. Although he is large, he has a cute and unexpected charm with a lot of charm and talent.

After the performance, you can even touch the walrus, so be sure to watch your friends' performance until the end!

A cute performance by a captivating dolphin

Umitamago's dolphin show stage is very close to the audience! It will captivate you with its powerful jumps and cute performances. Cool off from the hot summer heat with the cool splashes of dolphins!

Great tip here! The Dolphin Performance Hall has a great sea view, but it can be cold due to the strong sea breeze. We recommend bringing a jacket to protect yourself from the cold and splashing water. Also, I recommend going to the dolphin show right after the walrus show to secure the popular second floor seats.

* Please refer to the official website for detailed performance information and performance schedule .

Aso Beach, an artificial beach where you can meet marine animals

At 'Aso Beach', a shallow artificial beach for children, you can directly interact with dolphins and seals in the water. There is always a safety guard in front of the beach, so you can play with peace of mind.
