Nasu Bettei Kai is a ryokan in Nasu Yumoto, within Nikko National Park at the foot of the Nasu mountains, run by the company behind the neighbouring inn Sansuikaku. Each of its 10 rooms has its own hot-spring bath, and guests may also use the large bath at Sansuikaku next door. Dinner is served at the restaurant Jimiru, built around a charcoal grill and using local ingredients such as Tochigi wagyu and ayu sweetfish from the Naka River. Rooms range from 2-guest rooms that do not accept children to a room for up to 6.
