Snow cap fully formed by mid month. Clear cold mornings, high visibility around 60 percent.

Best time
Cold dry air and the long dormant season give December through February the highest Fuji visibility rate of any time of year. Plan around clear mornings and the deepest snow cover of the season.

Statistically the clearest month of the year. Diamond Fuji from Yamanakako early in the month.
Cold but still very clear. Last chance for deep snow cover before spring haze sets in.
