This is a small, small ski park. There is one challenge course, 2 or 3 short intermediate options and a longish, flatish cruising run if you take two lifts up to Minakami Kogen.
There was virtually nobody there apart from some school lesson groups in the afternoon (who only stayed for a couple of hours). A good place to learn/teach, brush up rusty skills, take the kids etc. Very, very pretty silver birch forest. Cheap lift ticket. (3500yen)
