The aquarium's highlight is the Big Petri dish, one of Japan's largest basin-shaped jellyfish tanks. The observation experience, not through acrylic but from above, and the lighting effects create stunning photos. In the Ogasawara Large Tank, a recreation of the waters of the Ogasawara Islands, visitors can enjoy the "Bonin Blue" world of sand tiger sharks and rays.

The Tokyo Large Tank, a recreation of the waters of the Ogasawara Islands, is themed around the waters off Tokyo's islands, including the Ogasawara Islands.

In the central indoor open-air pool, visitors can observe Magellanic penguins and fur seals up close. If the timing is right, visitors can learn about the lives of these creatures through interpretive programs such as "Penguin Feeding Time" and "Spotted Garden Eel Feeding Time."

This park-like aquarium offers a variety of ways to spend your time, including a café where visitors can enjoy a day of leisurely and leisurely watching the creatures.

The aquarium's concept of closeness between the animals and the staff also encourages visitors to feel closer to the aquarium.
