Visited Snowtown Yeti on 23 October, a Saturday, for a pre-season warm-up. They had been open a week, having laid down a ribbon of crushed-ice on their "A" course, served by a quad lift and a pair lift operating in parallel. The quad was ski-on, ski-off, while the pair was walk-on, walk-off. The first lift had a huge line to get on, probably about a 10 minute wait. The second almost none.
Visited Mt. Jeans in late December, 2008, on the day after a snow storm. I think it may even have been their first or second official day open of the season, due to a late start waiting for snow that year. It was a beautiful, sunny day.
The resort is very easy to get to by car, just 20+ minutes off the Tohoku Expressway. Quicker to get to than Hunter or Edelweiss even if coming from the south,
Edelweiss is on the Momiji Line between Kinugawa and Shiobara, just south of Hunter Mountain. There used to be a couple more ski areas neighboring to the south of it; they closed down and were dismantled a few years ago, though their remains can still be seen on google earth.
We went in January 2009, on a sunny but rather windy day. As a result, most of the lower slopes were a real chore to get around --
