Mifuchi Ravine

In the upper part of Nagai Dam, there is a deep valley called “Mifuchi”.
According to legend, Unohana Hime (Princess), the daughter of an influential family who ruled the Nagai area, tragically threw herself from a cliff due to troubles with love, and then transformed herself into a dragon that controls water.
There is a boat tour that carries people to Mifuchi Shrine where Unohana Hime, the girl who became a dragon, is enshrined, and allows people to offer prayers from the boat.
