Sanage Onsen

Sanage Onsen rises in the hills of Kano-cho, Toyota City, Aichi, within the Aichi Kogen Quasi-National Park. Drawn from deep underground, it is one of the prefectures largest natural radon springs and has been called a medical spring. It is also known as the first hot spring in Aichi permitted for drinking, so the water can be enjoyed both in the bath and as a drink.
