▸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 spring temperature is a lukewarm 39.9°C, perfect for a long, relaxing soak. Its weakly alkaline nature is gentle on the skin, making it suitable for those with sensitive skin and children. To maximize its moisturizing benefits from the rich metasilicic acid, immerse your whole body and let the water gently envelop you.
With a weakly alkaline pH of 8.4 and a remarkable 208.0 mg/kg of metasilicic acid, a natural moisturizer, this is truly a spring for "silky skin." It gently removes old skin cells, leading to a dewy, hydrated feel post-bath. This gentle simple spring is also perfect for "deep relaxation," helping to release physical and mental tension. It's an ideal balneotherapy for days when you need to reset your mind and body away from the daily grind.
While the spring is gentle and suitable for most, it may not be for everyone. If you have health concerns or specific medical conditions, please consult a doctor before bathing.
