A sodium-led bicarbonate spring — classified as jūsō-sen in the Japanese soda-water tradition. Neutral pH (6.8 at the wellhead) puts it squarely in the country's beauty-water family, with the soft, smoothing feel that comes from HCO3 chemistry on the skin. It emerges cool (25.2 degC) so it is reheated for bathing. Mineralization of 6.7 g/kg gives it real body; the water is colorless and faintly mineral-tasting at the source, turning slightly yellow and cloudy after standing in the air.
