Self drive on December

Hi

I am planning to drive from Nagoya-shirakawago- takayama- mt Fuji- Tokyo
Would it be challenging during December
Worrying driving on the snowy road.

If you are worried about driving on snowy roads, don't drive to Shirakawago and Mount Fuji! Use public transportation instead. It tends to be really goo in Shirakawago, and relatively good around Mount Fuji, depending on where you want to go.
