It's a very high-end hotel, very close to Lake Shikotsu, but you can't see the lake directly from the room because it's blocked by cherry blossom trees, so it may be difficult to book a room during the cherry blossom season.
The public bathhouse has hot and cold pools, and there are popsicles to eat after bathing in the hot springs. They are all free. I booked a room with two meals. Dinner and breakfast were very traditional Japanese meals. The portions were not large and the taste was a bit unfamiliar.
There is a public lounge on the second floor, where you can make tea and sit by the window to watch the scenery.
The environment is quiet and it is very pleasant to walk to the lake. I happened to encounter three wild deer passing by, which shows that it is a very natural place.
In the summer, you can take part in lake tours and canoeing. I also saw people doing bird watching activities, and you may have to make a reservation in advance to participate.
