A strongly alkaline simple thermal water reaching pH 10.5 — high enough to give the slippery, soft feel of Japan's beauty-water family. It is only lightly mineralized at 181 mg/kg dissolved solids, but a generous ~80 mg/kg of metasilicic acid leaves the kind of thin silica film that makes skin feel noticeably smoother afterwards.
