Ryusenji Onsen
A natural hot spring flowing up from underground, with sodium chloride spring water. Its hypertonic salt content forms a film on the skin, making it extremely effective at retaining heat. Soaking after sauna and a cold bath warms tired muscles and joints gently, and is effective for relieving chills and fatigue. You can enjoy the natural hot spring in multiple baths, including Hotaru no Tansansen and the Naked King’s Bath. After bathing, your skin feels smooth and you continue to feel less chilled. For those troubled by muscle pain, joint pain, or sensitivity to cold, the combination with sauna is the ultimate healing experience.
