The big open-air bath of a hot spring to well up from the bottom of river


Shiriyaki hot spring well up from the bottom of Nagasasa River. It is famous for the whole of the river being an open-air bath. Dams are built in the upper and the lower reaches, and hot water collects there.

This hot spring rather looks alike a pool than to be mixed bathing. Therefore, most people wear a swimsuit. It was trouble- some to us because there was no place to change our clothes. It is said that this hot spring is good for the piles.

A part of the river is a hot spring. Generally it is tepid. The part of the river that a hot spring wells up is hot. It is a bathtub in the place where the bottom of the riverit was deeply dug. There are three hidden bathtubs.
