Classification
Sodium Chloride-Bicarbonate spring
Beppu's municipally-run Unsenji source is a hot (64.1 °C) sodium chloride spring laced with bicarbonate softness. The pH sits at 7.4 — close to neutral with a faintly alkaline lean — so the water feels mild rather than sharp. Metasilicic acid at 158 mg/kg leaves a thin silica film on the skin, the kind that reads as gentle moisturisation rather than heavy mineral coating. Total dissolved solids run only 0.764 g/kg, so this is a lighter, skin-leaning hot water rather than a dense mineral soak.
