A gentle simple thermal spring of Yunoura Onsen, emerging at 39.3 °C. Weakly alkaline and hypotonic, it sits well within the soft, easy-on-the-skin family of Japanese simple springs. Total dissolved solids are light at 494 mg/kg, and the wellhead carries a faintly sweet taste with a soft hydrocarbon note — an unobtrusive, settled water rather than an assertive one.
