This was a main hotel for the G8 Summit in 2008, thanks to its amazing views and relative isolation on a mountaintop, for security. On one side you'll see the Pacific Ocean. On the other is the Lake Toya caldera, with it's adjacent active volcanoes.
The downside is being a half-hour's drive from Toyako Onsen, the nearest city. Also, when you check in, the staff will badger you to make restaurant reservations.
The bakery here is top notch, so the hotel is good for drives and picnics even if you're not staying here.
