The Kuchisakamoto No. 2 source is a municipally operated well in a mountain hamlet of Shizuoka City. A sodium bicarbonate spring of the classic jūsō-sen style, it emerges with a visible evolution of gas and a faint hydrogen-sulfide note. At pH 9.0 the water is alkaline, sitting in Japan's beauty-water family with a noticeably slippery feel on the skin. Moderate mineralization (1,188 mg/kg) plus metasilicic and metaboric acids round out a soft, smooth bath.
