Among the attractions at the Fish Museum, the diorama tank reproducing the Shimanto River ecosystem is a must-see. Freshwater fish from upstream to the mouth of the river are realistically displayed, and their expressions and movements are soothing to the heart. You can also see rare fish such as Akame and Pirarucu. It's a valuable spot where you can feel the beauty of the Shimanto River in the nature-rich town of Matsuno.
