A sodium-led bicarbonate-chloride spring — a jūsō-sen base with the salty edge of a chloride sub-type layered on top. Neutral pH, a faint hydrogen sulfide note on the nose, and 64.7 °C at the wellhead. Metasilicic acid at a generous 119.5 mg/kg leaves a thin silica film that smooths the skin, while 5,704 mg/kg of dissolved solids gives the water noticeable body.
