Classification
Calcium Sulfate spring
A hot (50.2 °C) simple thermal spring in Ebino, Miyazaki, served from a mixing tank on the city-run Shiratori upper-bath line. Weakly acidic in cert terms — pH 3.8 at the wellhead, falling to pH 3.43 in the lab — the water shows a faint milky turbidity, a slight metallic-and-sour edge on the tongue, and a soft hydrogen-sulfide note. Total dissolved solids are light at 170 mg/kg, but a modest 64 mg/kg of metasilicic acid leaves the skin feeling noticeably smoother on emerge.
