Quick answer: unlike cherry blossoms, autumn colors move from north to south and from mountains down to the cities — so “peak season” depends heavily on where you’re headed. Japan’s official 2026 forecast isn’t out until around September, so for now, plan around last year’s actual timing.
2025 reference dates (most recent data):
| Area | Peak window |
|---|---|
| Hokkaido (Asahikawa area) | Late October |
| Oku-Nikko highlands | Early–mid October |
| Lake Chuzenji (Nikko) | Mid–late October |
| Nikko city | Early–mid November |
| Kyoto | Mid-November to early December |
| Tokyo | Late November to early December |
Why the order is reversed from cherry blossoms: colder northern and high-altitude areas cool down first in autumn, so Hokkaido and mountain areas like Oku-Nikko peak weeks before Tokyo, Kyoto, or Osaka at sea level.
Planning tip: exact dates shift by a week or two depending on how warm the autumn is — 2025 ran later than average due to a warm October. If your trip is built around foliage, book accommodation with free cancellation and lean toward the later end of these windows rather than the earliest date.
FAQ
- When does the official 2026 forecast come out? Typically around September, about 6–8 weeks before peak color in most areas.
- Is autumn less crowded than cherry blossom season? Generally yes, though popular Kyoto temples still get busy on weekends during peak weeks.
- Can I catch both Nikko and Kyoto in one trip? Yes — visit Nikko in mid-October for the highlands and lake, then Kyoto in late November for the temples, since their peaks land roughly a month apart.
