A pH 10.0 simple thermal spring on the shore of Lake Yamanaka — strongly alkaline, with the pronounced slippery feel of Japan's beauty-water family laid over a very lightly mineralized body (just 172 mg/kg dissolved solids). The base water is gentle and almost unscented, but the high pH gives the skin a distinctly soapy glide. A cold-mineral source at 26 °C, so it is reheated for bathing.
