Harubo Onsen Spring No. 1Sodium Carbonate-Bicarbonate spring
A simple-type cold mineral spring that qualifies as an onsen on the strength of its metasilicic acid rather than any therapeutic anion. At pH 9.2 it is genuinely alkaline, giving the slippery, soft feel of Japan's beauty-water family. It carries 70.4 mg/kg of metasilicic acid, which leaves a thin silica film that makes skin feel smoother. Lightly mineralized and gentle on the body, and being a cold mineral source at 24.8 °C it is reheated for bathing.
