Mixed SpringMixed source
Sodium Bicarbonate spring
A blended source at Umegashima Onsen classified as a simple sulfur spring. At pH 9.76 it is strongly alkaline, giving the water a pronounced slippery feel, and at the source it carries a faint greenish-yellow tint with the unmistakable faint rotten-egg note of H₂S. With 65.4 mg/kg of metasilicic acid, it leaves skin feeling smooth.
