Yumoto ryokan is big and elegant, we enjoyed staying even if only for a night. Kaiseki dinner was so cool, everyone helped us understanding how it works. Also, the breakfast was huge and delicious, savory rather than sweet. The private bath is really worth the money, a beautiful experience. Also, we loved the lantern and the yukata provided in the room. Green tea was also provided and was a true relief. Unzen hell is right outside the hotel and is an incredible place to spend the afternoon. Would totally recommend.
