For uncrowded slopes and bluebird days: March brings with it more fine weather and fewer people hitting the slopes. It’s a great time to head over if you prefer to ski or snowboard on piste or are still learning the ropes. In mid-late March accommodation and lift ticket discounts are common.
For families: If you’re limited by school holiday dates it can be tricky as Christmas – New Year is also an extremely popular time for local Japanese to ski or snowboard. There is a bit of a sweet spot in the third week of January (before Chinese NY) where you will find better accommodation availability and less people on the slopes.
Dates to avoid: Chinese New Year falls on 28 Jan – 3 Feb in 2017 meaning the slopes and accommodation will be full to the brim over these dates!
