Ryusenji Onsen
An alkaline simple hot spring that rises from 2,000 meters underground. The water is colorless and transparent, with a soft, gentle feel on the skin. In the panoramic open-air bath, you can soak in natural hot spring water while admiring a night view sparkling like scattered jewels, spending a truly luxurious moment worthy of being called a sky bath. High-concentration carbonated springs are also available.
