A simple thermal spring from Enzohara in Yamanashi City. At pH 9.5 it tips into the strongly alkaline range, giving the pronounced slippery feel that defines Japan's beauty-water family. Lightly mineralized at 158.6 mg/kg total dissolved solids, but a generous 51.3 mg/kg of metasilicic acid leaves a thin silica film that makes skin feel noticeably smoother afterwards.
