Rishiri Fuji Hot Spring Pool A "footbath" is now available next to the Yuyukan! The heat of the water is about 35 degrees Celsius, the same as the source. The temperature is set at a comfortable level. The period of use is from early June to mid-October. There is no charge for use. Why don't you take a break from your daily work while surrounded by the forests of Rishiri? There is a "Historical Forest Walk" in the adjacent virgin forest, so it is recommended to heal your feet after walking through the forest!
