A sulfur-bearing sodium spring that stacks sulfate, bicarbonate and chloride in that order. The water itself runs colorless and clear, but a moderate hydrogen sulfide note rises off it and a sulfurous taste lingers on the tongue — the unmistakable rotten-egg signature of H₂S. It is weakly alkaline and soft on the skin, moderately mineralized with noticeable body, and carries enough metasilicic acid to sit in Japan's beauty-water family, leaving the kind of thin silica film that makes skin feel smoother afterwards. At the source it also ranks among Japan's hottest natural waters.
