Question 1

Will I catch autumn leaves in Nagano in November 21–30?

Accepted Answer

In an average year, Nagano's autumn leaves reach peak color around November 12. For a November 21–30 trip, the chance of overlapping peak color is ~37%, and the chance of seeing at least some autumn color is ~37%.

Question 2

What will the trees actually look like in November 21–30?

Accepted Answer

Across November 21–30 in an average year, expect roughly 8.5 days of falling / past peak, and 1.5 days of peak colour. Past peak — colours fading and leaves coming down. Gingko carpets can still be striking.

Question 3

What if I miss peak color in Nagano?

Accepted Answer

This window is a stretch in Nagano — on the same dates you'd likely have better odds in Osaka (96%) or Hiroshima (95%) instead. Or shift your own trip a few days earlier toward the peak (around November 12).
