January marks the start of a new year but it is also the unofficial start of backcountry season. By this time all the mountains in the area have been accumulating snow and there are powder stashes to be found everywhere if you know where to look. It is also a peak period for tourists so you may find a lot of the resort areas get tracked out pretty quick by the holidaying masses.
Why not get out of your comfort zone, utilize some local knowledge and get a fully qualified local guide to take you on foot or by snowmobile to some hidden spots around the area or up the famed Mt Yotei.
