A sodium-calcium chloride spring rising unaided at Shima, with sulfate adding quiet body to the water. The pH is neutral and the mineralization moderate at 1,880 mg/kg, so the water has noticeable substance without any sharpness. A generous 133 mg/kg of metasilicic acid puts it in Japan's beauty-water family: the silica leaves a thin film that makes skin feel smoother once you are out of the bath.
