An alkaline simple thermal spring led by sodium and calcium with a touch of sulfate and chloride. At pH 8.8 it sits firmly in Japan's beauty-water family, with the slippery, skin-smoothing feel that comes from the alkaline-bicarbonate side of the spectrum. Lightly mineralized at 371.9 mg/kg dissolved solids — a gentle, low-irritation soak. The 31.7 °C source is reheated for bathing as a cold-low spring.
