A blend of two wells at Beppu Kamenoi Hotel, classified as a simple thermal spring. Hot at 43.5 °C, weakly alkaline at pH 7.6, and soft on the skin. Total dissolved solids are light at 721.8 mg/kg, but a generous 195.6 mg/kg of metasilicic acid leaves the kind of silica film that puts it squarely in Japan's beauty-water family.
