How Koyo Forecasts Work

Japan Meteorological Corporation (Weathermap) releases annual forecasts in early September based on temperature projections. A warmer autumn delays the season; cooler advances it. Check the annual forecast when released for accurate timing.

Planning Around the Forecast

For Kyoto — the most crowded koyo destination — book accommodation as soon as the forecast is released (early September). Aim for November 20–December 7 as a reliable window if exact dates aren’t yet confirmed.

Best Strategy

Follow koyo from north to south: early November in Nikko/Tohoku, mid-November in Tokyo, late November in Kyoto and Osaka. Always chasing peak color rather than competing with everyone at the same location.
