A sodium-led chloride spring with bicarbonate softness layered in, emerging at a striking 75.8 °C — among Japan's hottest natural sources. Weakly alkaline, with a faintly salty tang on the lips and a quiet, moderately mineralized body. A generous 125.7 mg/kg of metasilicic acid leaves the kind of silica film that smooths the skin, placing it firmly in the Japanese "beauty-water" family.
