Inawashiro is just off the Banetsu expressway, and is two resorts in one. The older resort is challenging, with steep upper runs but plenty for beginners too. I have been three or four times, and it always challenges me differently. The newer part of the resort is great for learners, but also has a kind of Super-G course too - piling down that was excellent.
The snow park hasn't got a half pipe this year, but there is a big jump, a couple of rails and a table top - although they do shut it at about 2pm.
In Fukushima, it is one of the most accessible and nicest places around, and is pretty popular with local gaijin too.
