A sodium-led bicarbonate spring — the classic 'jūsō-sen' style, soft on the skin in the Japanese 'beauty-water' family. Weakly alkaline, moderately mineralized at 2,400 mg/kg dissolved solids, and emerging hot at 53 °C from the source. A generous 85 mg/kg of metasilicic acid adds the silica-film feel that leaves skin noticeably smoother afterwards.
