A municipal Beppu blend (Unsenji source plus others, sampled at a covered mixing-tank outlet) emerges hot at 64.1 °C as a simple thermal water, neutral and hypotonic. Total dissolved solids sit modestly at 0.764 g/kg with a faint sodium-chloride lean, so the water reads gentle rather than briny. The headline is silica — metasilicic acid at 159 mg/kg leaves the kind of fine film that makes skin feel noticeably smoother on the way out.
