A sulfur-bearing sodium-calcium chloride-sulfate spring that rises under its own pressure at 97 °C — among Japan's hottest natural sources, and necessarily cooled before it reaches a bath. At the wellhead the water is almost colorless and clear, yet it carries a frank sulfurous taste over a light saltiness and the unmistakable rotten-egg note of H₂S. Weakly alkaline and soft on the skin, it also runs a generous 219.6 mg/kg of metasilicic acid, putting it squarely in Japan's beauty-water family, while the chloride and sulfate load gives the moderate mineralization a warmth that lingers well after the bath.
