Classification
Sodium Bicarbonate-Carbonate spring
An alkaline simple sulfur cold-mineral spring that carries a faint rotten-egg note of hydrogen sulfide at the source, with fine white suspended matter. Its high pH gives the slippery feel of the Japanese beauty-water family, and as a cold-mineral source below 25 °C it is reheated for bathing.
