Kurama Onsen Gensen No.2
Analysis UnverifiedEmerging from a tea field near the gate of Kurama-dera Temple in Kyoto's "inner parlor" during the late Meiji era, this rare and esteemed hot spring offers subtly sulfur-scented waters. Its gentle, weak alkaline touch smoothly envelops the skin, leaving it with a silky feel. After bathing, a refreshing lightness of body and mind promotes rejuvenation. It provides deep relaxation, helping to relieve pain from journeys exploring Kifune Shrine and Kurama-dera Temple, allowing visitors to deeply refresh amidst the beauty of nature through the four seasons.
The bar length shows how abundant each component is compared to thresholds that make it "distinctive" (therapeutic spring standards, beauty spring criteria, etc.).
The aroma typical of sulfur springs, with circulatory and antibacterial effects.
A rare radioactive spring where trace radiation absorbed via inhalation and skin is expected to stimulate cells (the "hormesis effect").
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 cold mineral source is heated for bathing. This weakly alkaline sulfur spring is gentle on the skin, making it suitable for long soaks. It is recommended to warm up slowly while enjoying the mountain scenery from the open-air bath. Remember to stay hydrated before and after bathing.
The weak alkalinity of pH 8.5 gently removes old skin cells, leaving your skin feeling smooth. As a simple sulfur spring containing 8.6 mg/kg of total sulfur, it is said to promote blood circulation and aid in recovery from neuralgia and fatigue. It's the perfect bath to soothe a tired body after a nature walk in Kurama.
Please avoid bathing if you have general contraindications such as active illnesses or severe heart disease. As a sulfur spring, those with sensitive skin or mucous membranes should be cautious. Remove precious metals as they may tarnish.
