Our spring water is very rich in minerals, so sediment-like particles may appear.
White deposits on the rock bath are yu-no-hana—crystallized mineral components.
They indicate high-quality spring water. Please enjoy your bath with confidence.

Our sauna was fully renovated in 2025. Enjoy hot-and-cold contrast bathing along with 100% natural spring water. Separate men's and women's self-löyly saunas scented with hinoki cypress, set to a comfortable ~85°C for deep sweating.
