Question 1

Will I catch autumn leaves in Hiroshima in December 11–20?

Accepted Answer

In an average year, Hiroshima's autumn leaves reach peak color around November 22. For a December 11–20 trip, the chance of overlapping peak color is ~0%, and the chance of seeing at least some autumn color is ~0%.

Question 2

What will the trees actually look like in December 11–20?

Accepted Answer

Across December 11–20 in an average year, expect roughly 10 days of falling / past peak. Past peak — colours fading and leaves coming down. Gingko carpets can still be striking.

Question 3

What if I miss peak color in Hiroshima?

Accepted Answer

This window is a stretch in Hiroshima — on the same dates you'd likely have better odds in Yokohama (77%) or Shizuoka (Fuji area) (72%) instead. Or shift your own trip a few days later toward the peak (around November 22).
