The aquarium focuses exclusively on marine life native to the Seto Inland Sea rather than exotic species.
The touch pool allows visitors to handle creatures like starfish, sea cucumbers, and various crustaceans found in the local tide pools.
The facility is integrated into a larger park area that includes coastal walking trails and regional scenery.
It is managed with a focus on environmental education and local biodiversity conservation for Suo-Oshima.
Nagisa Aquarium is a compact, community-focused facility located on the eastern end of Suo-Oshima Island in the Seto Inland Sea. Its primary feature is a large, open-air touch pool designed to provide direct interaction with local marine life. The facility houses approximately 150 species of fish and invertebrates native to the surrounding waters of the Suo-Oshima area. Unlike large-scale commercial aquariums, this venue emphasizes educational engagement with the regional ecosystem. It is situated within the grounds of the larger Nagisa Park complex, which overlooks the coastal landscape.

Wear comfortable, non-slip footwear as the proximity to the ocean and water features can result in damp walkways.
Bring a small towel, as the hands-on experience in the touch pool will leave your hands wet.
Plan to explore the surrounding Nagisa Park trails, as the aquarium visit is quick.
Expecting large-scale exhibits, shark tanks, or performance shows; this is a small, specialized educational venue.
Closed on Wednesdays. If a national holiday falls on a Wednesday, it is usually closed the following day.
Refrain from lifting marine animals entirely out of the water in the touch pool; keep them submerged.
