If you need any tips, let me know. I live here.
It's all good up here in Hokkaido. It's like nothing has happened. Been skiing since the earthquake, and a few resorts will be open till early May.
A few of the resorts down in Fukushima got messed up and around there have lost a few lift towers etc, but some things are still open. (Less and less now, due to the season coming to an end, and generally people not wanting to ski)
