Benitsubaki-no-yu (Reisen)
Analysis UnverifiedWelling from Kotsuki in Michi Village, this registered spring offers a gentle experience. As a hypotonic alkaline sulfate spring, it moisturizes skin effectively. The cool temperature brings mental clarity, making it ideal for those seeking deep relaxation and silky 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.
Due to the low temperature, soak for a longer duration to warm your body thoroughly. The alkalinity leaves skin smooth, so follow up with moisturizing care.
With a pH of 8.7 and 1179.9 mg/kg of sulfate ions, this spring helps refine the skin barrier for silky skin. Its hypotonic nature allows rapid absorption, potentially relieving pain and promoting deep relaxation. Ideal for those dealing with stiffness or cold sensitivity.
As a cold spring, it may feel chilly initially; acclimate gradually. Being alkaline, avoid getting water in eyes as it may cause irritation.
