A gentle alkaline simple thermal spring. The high pH gives the slippery, soft-on-the-skin feel of Japan's beauty-water family, leaving skin smooth after a soak. It carries about 51 mg/kg of metasilicic acid, enough to leave a thin silica film that makes skin feel noticeably smoother. Lightly mineralized overall, it is an easy water for a long, unhurried bath.
