Cherry Blossom Planner

Free tool · JMA 1991–2020 normals · No signup

Most sakura pages tell you when Tokyo blooms. The useful question is the other way round: you already have dates — which cities will be in blossom while you're there? Enter your trip below and every city gets an honest verdict, including the ones you'd have to be lucky to catch.

Read this before you book flights. These are 30-year averages, not a forecast. Real years land roughly a week either side of them, and warm winters have been pushing dates earlier. Nobody — including the JMA — can tell you 2027's dates in September. What the averages can do is stop you booking a week that would need a miracle. Live forecasts start appearing in late January and firm up through February; that is when you commit to a specific temple.

How to read the verdicts

The flowering window runs from kaika (first bloom, the sample tree opening) to about five days past mankai (full bloom, roughly 80% open). That's usually 10–13 days per city, and the wave moves south to north over six weeks — which is the whole trick: if your dates miss Kyoto, they may well hit Kanazawa or Sendai.

Blossom trips need tighter planning than normal trips

Sakura season is the one time Japan genuinely sells out. The printable Japan Travel Planner has the booking timeline that says what to lock in and when — flights, hotels, and the reservations that vanish first — plus daily pages with a backup-plan row for the days the trees aren't cooperating.

Where the numbers come from

The Japan Meteorological Agency keeps designated sample trees in each city and records the day they open and the day they reach full bloom. The dates here are the published 1991–2020 normals — the 30-year averages for those same trees. They describe the city's typical timing, not any particular year, and not any particular park: a sheltered temple garden can run days ahead of a windy riverbank in the same city.

Two things the averages hide. Sapporo's late date is partly species — its observed tree is often Ezo-yamazakura, which flowers later than the Somei-yoshino used almost everywhere else. And the recent trend is earlier: several of the last ten years opened ahead of these normals in the big Honshu cities.

Once you have a shortlist of dates, the itinerary builder turns them into a route, and the cost calculator prices it — set the season to Peak, because blossom season really is the expensive one.
