Natural Hot Spring
A sodium-chloride strong saline hot spring that wells up from underground. With a high salt concentration, the bathwater has a salty film-like feel, warming the body from the core with excellent heat retention. After bathing, it is hard to cool down, and the feeling of relaxation from the core continues. You can enjoy various baths such as open-air rock baths, open-air reclining baths, and plain hot water, with the sensation and warmth differing in each bath. The unique bathing effects of chloride springs are expected to be effective for cold sensitivity, muscle pain, joint pain, and fatigue recovery. After bathing, the skin feels moist and smooth.
