Classified as an alkaline simple weak-radon spring — a gentle, lightly mineralized water of the simple-thermal type. With dissolved solids of only 140 mg/kg it sits at the light end of the scale and feels soft on the skin. Being alkaline, it carries the slippery touch of Japan's beauty-water family, even though its mineral content is modest.
