A sodium-led bicarbonate spring with a chloride tail — classic jūsō-sen territory and exactly the chemistry that earned Ureshino its reputation as one of Japan's three great beauty-water springs. The water emerges remarkably hot (88.3 °C, among Japan's hottest natural sources) and is weakly alkaline, so the soak carries that signature slippery, skin-softening feel. Moderate mineralization (1,905 mg/kg dissolved) keeps the body light, while 140.6 mg/kg of metasilicic acid adds a faint moisturizing film.
