"It's an overall excellent hotel with some minor annoying room design problems. It is fairly new, but imitates traditional onsen resort hotels. Most guests were Japanese. There is English speaking staff when needed. The breakfast and dinner was excellent. Mostly Japanese traditional, Gunma regional, and a few French items. The amount of food is large. It is Kaiseki style which means they give you a sampling of many small and medium dishes. It is a good way to learn about kaiseki and Japanese food. They provide English or Japanese menus to explain what the many dishes are. You may not like everything and you should not feel you must eat everything. They understand that. The atmosphere of the dining area is superb.
The outdoor onsen is the famous Kusatsu water. Fairly large. Not too crowded. The surrounding trees and bushes are relaxing. The staff maintains the onsen well.
The rooms are beautiful, and spacious. But poor design choices were made. The bright entrance light goes on by sensor. You can't stop it from turning on at night. The loud INAX toilet has a ridiculous flowing water white noise feature turned on by default at loud volume. You need to turn it off all the time. The sliding door clicks loudly when closing. Did the designer forget two people share twin rooms? The beds are surrounded by a raised low wooden platform. Beautiful, but non functional. It's awkward to sit at the edge of the bed.
The bus station and Yubatake are short walks away on sloping streets."
