A gentle simple thermal spring: Kiyousen draws on the No.1 and No.2 wells in Beppu's Kamegawa district and feeds them together into the bath. Neutral in pH and lightly mineralized at 0.73 g/kg of dissolved solids, it makes for an unfussy, low-irritation soak. What lifts it is silica — metasilicic acid at 193 mg/kg, enough to leave the thin moisturizing film that puts this water in Japan's beauty-water family. Note that the sample for this analysis was taken at the bath inlet rather than at the wellhead, so the figures describe the water as it actually arrives in the tub.
