A sodium- and magnesium-led bicarbonate spring — soft, skin-smoothing water of the jūsō-sen (soda) style, sitting squarely in Japan's beauty-water family. Metasilicic acid is strikingly abundant at 270.7 mg/kg, leaving the thin silica film that makes skin feel noticeably smoother after the bath. The posted indications back up the skin story: cuts, burns and chronic skin conditions are listed alongside the usual recovery and circulation items. The poster also notes the source holds no drinking permit — this is bathing-only water.
