Using the Seasonal Forecaster

When cherry blossom, koyo, and festivals actually happen, by city.

The Seasonal Forecaster tracks natural phenomena (cherry blossom, autumn colour) and scheduled events (fireworks, snow festivals, illuminations) across Japan, blending live data with forecasts and historical averages depending on how far out your dates are.

The free tier covers 10 marquee cities spanning Okinawa to Hokkaido. Adventure+ shows the full list of around 25 tracked cities.

Email alerts for a phenomenon you’re watching are free for any signed-in account, sign in to turn one on, no upgrade required.
