Miyajima Public Aquarium, also known as Miyajima Marine Circuit, specializes in the aquatic life of the Seto Inland Sea. The facility houses over 13,000 creatures representing approximately 350 species, focusing on local biodiversity. Distinctive exhibits include a reconstruction of the local tidal flats and a dedicated area for the region's famous oysters. The aquarium features an outdoor performance area where sea lions and penguins are displayed. Unlike larger marine parks, it emphasizes conservation and the environmental connection between the inland sea and the island's human population.
