Ohara Onsen
Analysis VerifiedOpened in 2004, Ohara Onsen in Kyoto's Ohara district offers a colorless, transparent spring nestled in a mountain village near renowned temples like Sanzen-in and Jakkō-in. Its signature feature is a gentle, soft texture that delicately envelops the skin. Immersing yourself in this weakly alkaline, smooth water amidst the ancient capital's tranquility will slowly release tension from your stiff body and mind. This onsen is perfect for those seeking serene moments surrounded by abundant nature, far from the daily hustle.
The bar length shows how abundant each component is compared to thresholds that make it "distinctive" (therapeutic spring standards, beauty spring criteria, etc.).
Mild antibacterial action keeps the skin clean. Trace transdermal absorption supports tooth and bone health.
A trace component with gentle antibacterial and anti-inflammatory action.

▸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.
With a gentle temperature of 26.0°C, this lukewarm spring is ideal for long, relaxing soaks without straining the body. The mildly alkaline water is soft on the skin, leaving you feeling refreshed afterward. Taking your time to soak allows for deep mental and physical relaxation.
Although a low-temperature spring at 26.0°C, its main component, hydrogen carbonate ions (222.3 mg/kg), is expected to have a smoothing effect on the skin. Its mild alkalinity makes it perfect for those with sensitive skin or for days when you want a long, leisurely bath. It is also suitable for therapeutic stays to alleviate chronic muscle/joint pain and poor circulation.
Please avoid bathing during active stages of illness, especially with a fever, or if you are extremely weak. It is also contraindicated for individuals with severe heart or kidney disease, or active tuberculosis.
