About
Ryuzu no Yu is the bathhouse at the Toyohira Donguri Mura roadside station, built around a natural radon spring. Upstairs there are two indoor tubs kept at different temperatures, so you can move between the cooler and the hotter side. The water itself is clear and colorless. It's a straightforward day-use stop: wash, soak, then step out to the on-site soba restaurant or the gift shop, or sit in the free rest room afterward.
