A sodium-led bicarbonate spring of the classic jūsō-sen style, emerging hot at 48 °C from a 160 m bore. Weakly alkaline at pH 8.3 with the soft, slippery touch that puts it firmly in Japan's beauty-water family. A generous 184 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterwards.
