An alkaline simple thermal spring at around pH 9, classified as hypotonic and high-temperature. The water is almost colorless, transparent, tasteless and odorless, with the slippery feel of Japan's beauty-water family. A generous 76.8 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother, and the certificate lists general indications such as chronic skin conditions and recovery from fatigue.
