An Interactive Aquarium for the Whole Family.
Umitamago is an aquarium in a superb location overlooking the blue waters of Beppu Bay and the surrounding mountains. Based on the theme of “an aquarium where you can befriend animals,” it has become a popular attraction where visitors can interact closely with marine mammals such as walruses.
Its predecessor was Oita Ecological Aquarium Marine Palace, which opened in 1964, the 39th year of the Showa era. It attracted attention for introducing the world’s first circular tank with a tidal-current system and hosting Japan’s first sea otter show. The facility reopened on a larger scale in 2004, the 16th year of the Heisei era, and was renamed Oita Marine Palace Aquarium “Umitamago.”
One of the main attractions of Oita Marine Palace Aquarium “Umitamago” is the opportunity to watch performances by walruses, Steller sea lions, dolphins, and other animals at very close range. Visitors may also have the chance to interact with the animals after their performances. At ASOBEACH, a play pool lined with white coral sand, dolphins may even swim up close to visitors. Many tourists combine a visit with the adjacent Takasakiyama Natural Zoological Garden, making this a classic Oita sightseeing itinerary for nature lovers.

The aquarium is clean and comfortable, and it’s easy to get around even with kids and a stroller. The large tank has all kinds of marine life, and the kids were so excited watching them. The biggest surprise for the children was seeing dolphins, walruses, and penguins up close. It felt really interactive.
