Wanted room / house to rent Nov/Dec - March/April

I need a room for the season but am having great difficulty finding anything!

Ideally I'd like a 3-5 bedroom house in the village - anywhere between the outskirts of Izumikyo and St Moritz (have about five friends who are in the same boat so would be good to get one house, although at this stage would settle for just a room).

We have cars so would consider something between Kutchan and Niseko town...

Any leads much appreciated!
