A hot spring district counted as one of Japan's great Three Ancient Springs alongside Dogo Onsen in Ehime Prefecture and Arima Onsen in Hyogo Prefecture. The area's natural sulfur springs, whose waters are drawn from some 50 meters below the surface, generate an astounding five tons of piping hot water every minute. The hypotonic, mildly alkaline high temperature sulfur springs here are a variety found almost nowhere else in the country and have been used for over 1,000 years. Their colorless, slightly saline waters, freely distributed throughout the town, are said to enhance beauty, detoxify the body, alleviate hardening of the arteries, and ease high blood pressure. The town also cultivates balneotherapists, hot spring health technicians able to provide medical hydrology- and preventative medicine-based advice on hot spring therapy, and here visitors can consult with these qualified persons on how to healthily and best make use of hot spring baths.
