Urahoro Rushin Onsen Well No. 2
Analysis UnverifiedRising on its own from a well in Rushin, a quiet valley east of the Tokachi Plain, this spring carries only about 0.2 g of minerals per kilogram, yet its pH of 10.0 ranks among the most alkaline in Hokkaido. Sodium and carbonate dominate, giving the water a slippery, skin-softening feel. The cool spring is warmed for bathing, making it a gentle mountain-village bath for smooth skin.
The bar length shows how abundant each component is compared to thresholds that make it "distinctive" (therapeutic spring standards, beauty spring criteria, etc.).
Scores are calculated from mineral analysis data based on the Mineral Spring Analysis Guidelines (Ministry of Environment, Japan). They are unrelated to facility atmosphere or service quality.
▸Note
The temperature, pH and component values shown here are based on the hot spring analysis (source). Actual values in the bath may differ depending on heating, dilution, recycling and filtration. Please check current usage status at the facility.
At pH 10.0 the water feels slick; it lifts skin oils easily, so keep soaks moderate and moisturize afterward, rinsing lightly if your skin is dry.
With pH 10.0 and 63.1 mg/kg of carbonate, the water gently softens the skin's surface and is traditionally associated with silky skin, while this mild simple spring may support deep relaxation.
The strongly alkaline water may leave skin feeling dry; moisturize after bathing and avoid overly long soaks if you feel unwell.
