東山ニセコビレッジ温泉
Higashiyama Niseko Village OnsenSodium Hydrogen phosphate-Sulfate spring
A sodium-led sulfate spring emerging at a hot 49 °C, weakly alkaline (pH 7.7) and moderately mineralized at 1,422 mg/kg dissolved solids — settled, mineral-rich body on the skin. A generous 212 mg/kg of metasilicic acid leaves the kind of silica film that places it in Japan's "beauty-water" family, with skin feeling noticeably smoother afterwards.
