Classification
Sodium Bicarbonate spring
A sodium-led bicarbonate spring — the classic jūsō-sen style, soft and skin-smoothing on contact. Neutral pH with moderate mineralization (about 1,600 mg/kg dissolved solids) gives the water noticeable body without harshness. A generous 122 mg/kg of metasilicic acid leaves the thin silica film that puts this firmly in Japan's beauty-water family.
