The hotel had multiple onsen each of different style. Very enjoyable. The view from the room faced forestry, which would be beautiful in autumn when the leaves turned red. The sound on rushing water from the rapids nearby gave a soothing feeling. The service staff coordination was great too, when you arrive or checked out, they will ask for your name or room number, then inform recep or the car assistant to prepare your keys.
Things which were not great
1/ food at the buffet was often cold or like warm,other than soup.
2/ would have been nicer if it were kaiseki
