An alkaline simple sulfur cold-mineral spring: a faint hydrogen sulfide note drifts at the source and fine white particles float in the otherwise colorless, clear water. The alkaline pH gives it the soft, slippery feel of Japan's beauty-water family. At 17.5 °C it is a cold-mineral source (< 25 °C) reheated for bathing, and with only 651 mg/kg of dissolved solids the water sits light on the body.
