A hot 54.9 °C simple thermal spring of the Kurokawa area. Weakly alkaline and soft on the skin, it sits on the gentle edge of Japan's beauty-water family. A generous 177 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterwards, with a faint rotten-egg note of H₂S drifting at the wellhead.
