A hot (47.6 °C) alkaline simple thermal spring. At pH 9.44 the water has the slippery, skin-smoothing feel of Japan's beauty-water family. Mineralization is light at 350 mg/kg, but a generous 58.7 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterwards. A faint hydrogen sulfide note hangs over the bath.
