Yep, I agree with other reviewers who said this is a keeper. Four of us (me, husband, son, son's friend) stayed here as part of an 8-day Hokkaido road trip, and we all loved it. I'd goofed up our first night's reservation -- which was scary -- but they made room for all 4 of us in the family-size room on the 3rd floor. Two beds and two futons, and it was so fun that I kind of wish we'd remained in that room for the rest of our stay. Clean, bright, beautiful view (eagles!), and friendly service.
Didn't try the pizza, but we can recommend the crab place that's on the way to the boat launch in "downtown" Utoro. As you approach the restaurant, keep an eye out for the fox family (kitsune) that lives in the bushes right near it. The ramen place between the hotel and downtown (~15 minute walk) was also good.
Oh, and the boys saw a brown bear on their hike up Mt. Rausu -- although the hike had to be aborted due to snow (not the bear).
