Ichihara Onsen
An iodine-sodium-chloride high-salinity spring that bubbles up from 1,500 meters underground. The amber-colored water has a high salt concentration and is characterized by excellent heat retention and moisturizing effects that seem to cling to the skin. At the outdoor "Upper Bath," you can enjoy the natural free-flowing spring water and feel the power of the fresh hot spring. After bathing, your body stays warm and cozy for a long time, gently easing away fatigue from deep within.
