A sodium-led bicarbonate spring with a salty chloride edge, classified as a hot spring (47 °C at the wellhead). It belongs to the jūsō-sen (soda-water) family — weakly alkaline and soft on the skin, with the slippery feel of Japan's beauty-water tradition. A solid 74.8 mg/kg of metasilicic acid leaves a thin silica film that makes skin feel noticeably smoother. The water is colorless and transparent with a faint metallic note in taste and smell.
