Fish Museum

The Fish Museum mainly exhibits freshwater fish, including those from the Shimanto River, Japan's cleanest river. This aquarium introduces the wonders and charms of rivers and fish in a fun way, using audio guides to explain the incredible power of fish. In the open-air diorama tank, which displays the ecosystem from the source to the mouth of the river, the creatures show lively expressions that will soothe your soul. In addition, the "mythical fish" Akame, which lives in the mouth of the river, and the pirarucu, one of the world's largest freshwater fish, will captivate you with their large bodies and graceful swimming. You can also meet other unique animals, such as Asian small-clawed otters, adorable penguins, and the bipedal crocodile "Daigoro."
