A sodium-led alkaline simple thermal spring. It is only lightly mineralized at 206 mg/kg of dissolved solids, so it stays gentle on the body, while a notably alkaline pH of 9.5 gives the slippery, skin-smoothing feel of the Japanese beauty-water family. A generous 68.5 mg/kg of metasilicic acid leaves a thin silica film that makes skin feel noticeably softer afterwards.
