A sodium chloride hot spring on the Shirahama coast (source 56.6 C, neutral, hypertonic). Mineralization is solid at 18.18 g/kg — salty, heat-retaining water that leaves a fine mineral film on the skin. A generous 106.8 mg/kg of metasilicic acid puts it in the Japanese 'beauty-water' family, with skin feeling noticeably smoother after a soak.
