Natural hot spring open-air bath
TypeNatural Hot Spring
A charming natural hot spring open-air bath where Onuma's pleasant breeze blows through. The mildly alkaline simple hot spring water is gentle on the skin, with very soft and smooth texture. You can soak for a long time without easily getting overheated, and it gently eases muscle tension and fatigue. While looking out over the surrounding greenery and listening to the sound of the wind and birdsong, you can enjoy an open, refreshing bathing experience.
