Japan Meteorological Corporation, a private forecaster, published its first 2026 autumn leaves forecast on September 2. It expects autumn temperatures above normal across Japan, so maple color should arrive at a normal time or later than normal in most places. The next forecast is due in early October.
The dates below are the forecaster's peak dates for the reference maple in each city, not for any particular temple or park. Famous spots in the hills and suburbs often peak earlier than the city reference tree, so treat these as a guide to whether the season is running early or late.
The 2026 Forecast So Far| City | Forecast maple peak, 2026 | Compared with normal |
|---|
| Sapporo | November 7 | 10 days later than normal |
| Sendai | November 25 | Near normal |
| Tokyo | November 29 | Near normal |
| Kanazawa | November 30 | Near normal |
| Osaka | December 4 | Near normal |
| Kyoto | December 11 | Near normal (normal date December 5) |
