A sodium-led bicarbonate-sulfate spring carrying a sulfur signature — a hot 50.9 C source from the Naruko field with a layered chemistry. Weakly alkaline at pH 8.5, it gives the soft, slippery feel of Japan's beauty-water family. A generous 259.6 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterwards.
