Kawaji Onsen, Tochigi
At this quiet getaway nestled along a scenic wooded ravine, relax in lush hot-spring baths and enjoy sweets made with freshly ground flours and grains at our traditional water mill.
Enjoy the hospitality of the Tochigi area countryside. Guests are invited to use a small rotary quern to grind a variety of soybeans into a flavorful flour called kinako, or try making paper from unusual materials, like fall leaves picked from the ryokan courtyard.
