An alkaline simple thermal spring rising at Shotokuji in Yamanashi City. At pH 9.5 it is strongly alkaline, giving the pronounced slippery feel of Japan's beauty-water family. The water is only lightly mineralized and gentle on the body, but carries a generous 126.7 mg/kg of metasilicic acid, leaving the kind of thin silica film that makes skin feel noticeably smoother. At the source it is very faintly yellow and clear, with no taste or smell.
