Classification
Sodium Chloride-Bicarbonate spring
A hot Beppu Tsurumi-system source (58.5 °C) framed as a sulfur-bearing simple thermal spring, with sodium-chloride and bicarbonate as the chemical backbone and 4 mg/kg of free hydrogen sulfide on top. Total dissolved solids sit around 0.73 g/kg, so the body is light and the pH neutral — a low-tonicity, soft soak with a faint H₂S note. A generous 151 mg/kg of metasilicic acid adds a smooth, silky feel on the skin.
