Open-air source-fed hot spring
TypeNatural Hot Spring

An open-air source-fed hot spring bath located in the outdoor area for both men and women. The bath is filled directly with the natural radon spring without circulation so you can fully enjoy the spring’s freshness and components. Along with the breathing bath effect of the radon spring, the fresh sensation unique to direct-flow spring water envelops the body. Overlooking a garden of Sanba-ishi rock, you can enjoy a luxuriously indulgent moment that far exceeds a typical day-trip onsen.
