A naturally welling radon spring at Yunoyama Onsen, carrying about 137 Bq/kg of radon — enough to place it in the radon-spring tradition associated with the 'hormesis' idea. At pH 8.0 it is weakly alkaline and soft on the skin, and the water is almost colorless, tasteless and odorless. Lightly mineralized overall, it is documented for gout, chronic digestive complaints and neuralgia.
