A simple hot spring that gushes out at a rate of 400 liters per minute from 765 meters underground. The spring water, with a source temperature of 36°C, is provided directly from the source, offering a mildly alkaline and gentle texture that softly envelops the skin. After sweating in the sauna, soaking in this water gradually warms the body, and its high heat retention keeps you warm even after leaving the bath. It is said to be effective for chronic pain in muscles and joints, cold sensitivity, decreased gastrointestinal function, mild hypertension, and various symptoms caused by stress, making it ideal for therapeutic bathing to relieve everyday fatigue. Available in both outdoor and indoor areas.
