I will go to Nozawa onsen in the end of Fab of 2018 and travel the Matsumoto and look around Gagano. May I know there will snow during that period? Thanks. Pang
Nagano’s snowy season is usually between mid-December to late March. The mountains and areas such as Hakuba, Nozawa and northern Nagano will be quite snowy, but cities may be snow-free.
It changes from year to year, so check the forecast as your trip date approaches. I hope that answers your question!
