A sodium chloride spring rising at 99.3 °C — one of Japan's hottest natural sources, requiring cooling before bathing. The water is almost colorless and clear at the wellhead, with a faintly salty edge and a whisper of hydrogen sulfide. Weakly alkaline (pH 8.4), it sits in the classic Japanese 'beauty-water' family, and a generous 208 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterwards.
