Donokawa Onsen
The natural mineral spring of the Donokawa Onsen area has long been cherished locally as the beauty spring. It has a high radon content and is one of the country's most strongly alkaline simple hot springs with a pH of 9.9, characterized by an amazingly smooth, slightly viscous texture. After bathing you will notice your skin feeling moist and silky. In addition to a spacious main tub, there are outdoor baths including a jacuzzi-style tub and a waterfall jet bath, so you can fully enjoy this superb spring quality across a variety of baths.
