A textbook Hirugami-style alkaline simple thermal water, delivered as a blend of nine wells. Lightly mineralized (326 mg/kg dissolved solids) and gentle on the body, with the soft slippery feel that puts it in the Japanese 'beauty-water' family. The source emerges at a near-skin 36.3 °C, so it is reheated before bathing.
