Wonder if there'll be any snow at mid Dec in Shirakawa go? I'll only stay for one night there, but wonder if I should wear my outdoor shoes instead of just my sneakers for the whole Japan trip.
My outdoor shoes have significantly less cushioning so it's not really that great for city walking (which I will be doing for most of the trip) as I get slight heel pain and foot fatigue after a couple of hours in it despite already fitting it with gel heel cushions for more shock absorption, but it's adequate for light snow with a lot more grip and traction against wet and slippery surface.
Anyone has any advice?

I've checked historical weather data and it seems that light snow is possible but not likely and/or not that many days of snow in Dec. Should I just wear my sneakers?
