Question 1

Will I catch autumn leaves in Yokohama in December 1–10?

Accepted Answer

In an average year, Yokohama's autumn leaves reach peak color around December 14. For a December 1–10 trip, the chance of overlapping peak color is ~26%, and the chance of seeing at least some autumn color is ~83%.

Question 2

What will the trees actually look like in December 1–10?

Accepted Answer

Across December 1–10 in an average year, expect roughly 4.5 days of colours turning, and 4 days of still green. A mix: greens shifting to yellows and first reds, deepening daily.

Question 3

What if I miss peak color in Yokohama?

Accepted Answer

This window is a stretch in Yokohama — on the same dates you'd likely have better odds in Osaka (95%) or Kobe (85%) instead. Or shift your own trip a few days later toward the peak (around December 14).
