Kamisunagawa Dake Onsen Panke no Yu Spring
Analysis UnverifiedAnalyzed in 2009, this cold mineral spring flows naturally at the foot of Mount Kamisunagawa in Kamisunagawa, a former coal-mining town in Sorachi. It emerges at a chilly 11.4°C with a classic baking-soda profile: sodium makes up about 80 percent of the cations and bicarbonate about 90 percent of the anions. With 1.203 g/kg in total and only 38.7 mg/kg of chloride, it is a straightforward, smooth water in hills that still remember the mines.
The bar length shows how abundant each component is compared to thresholds that make it "distinctive" (therapeutic spring standards, beauty spring criteria, etc.).
A trace component with gentle antibacterial and anti-inflammatory action.
Absorbed through the skin to gently promote peripheral circulation.
- Bicarbonate (baking soda)786 mg/kg
- Feel
- Your skin feels smooth and silky.
- Said to
- Said to remove old skin cells and excess sebum. Bathing indications include cuts, poor circulation and dry skin.
- Note
- It can leave skin dry—moisturize after bathing.

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.
The 11.4°C source is heated for bathing. Bicarbonate water rinses away sebum and leaves skin smooth, so moisturize afterward, and dry off well in Sorachi's cold winters.
With 785.7 mg/kg of bicarbonate, this baking-soda water is traditionally valued for silky skin and a refreshing sense of rejuvenation.
The cool 11.4°C source is heated for use and is not for drinking. Watch for dry skin after bathing, avoid bathing on an empty stomach or after alcohol, and drink water before and after.
