It was a great December, so a decent base was laid down. January has been a little less snowy, but still has had some decent snowfalls. Looks like this weekend coming should be a good one.
By that time in Feb, you still should have a lot of powder days, although it won't be quite as consistent as earlier in the winter. But you should get a few clear days for getting out and touring. Plus is shouldn't be as busy.
The gates out of Niseko should be open, barring bad weather, or unstable snow. Tons of options with not much hiking involved. It's worth getting out if possible to check out Moiwa, and Chisennupuri - smaller areas, next to Niseko which are less crowded, cheaper, but get the same pow. Also Rusutsu is great for a couple of day trips.
I ride at Rusutsu alot, so if you happen to be there when I'm there, I'll happily show you around. Drop me a line on here.
Looks like we've got a big storm coming in right now. Should be dumping for a good couple of days. I'm heading up to Asahidake, the tallest mountain in Hokkaido. Should be deeeeeep.
