Nasu Onsen

The Nasu Onsenkyo hot spring district sprawls along the side of 1,915 meter tall Mt. Chausu, Tochigi Prefecture's only active volcano. The Nasuyumoto Onsen (Shika no Yu) hot spring boasts the longest history of any on the mountain and was discovered some 1,380 years ago in 630. It is the 32nd oldest discovered hot spring in Japan and the oldest in Tochigi Prefecture, having been discovered even earlier than even Shiobara and Nikko's vaunted waters. Today, the waters of this sulfur spring are used by the Shika no Yu public bathhouse, which stands near the famous Killing Stone, a rock which legend says was once a tricky nine-tailed fox. The waters of this spring are said to treat such ailments as skin diseases, women's diseases, gastrointestinal disorders, and fatigue. Piping hot, they range from 63 to 80° C, and because the bathhouse also keeps the temperatures of its tubs quite high, it recommends bathers make use of a unique system of timed bathing handed down since ancient times in order to avoid overheating.
