An alkaline simple thermal spring (pH 8.9) sitting squarely in Japan's beauty-water family — the high pH gives the characteristic slippery feel on the skin. At the wellhead the water carries a faintly salty tang and a whisper of hydrogen sulfide; emerging at 36.7 °C, it is pumped up rather than free-flowing and would normally be reheated. Lightly mineralized at 475.7 mg/kg, the chemistry is gentle and undemanding — a soft, easy soak rather than a strong-mineral plunge.
