Sakura is the most over-anticipated travel target in Japan, and the only one where missing the peak by three days will reshape your entire trip. The season lasts about two weeks per region, but full bloom (mankai) is a five-day window. Forecasts (the official JMA blossom map) update weekly from January onward; serious sakura-chasers book refundable hotels in two cities and decide which to visit a week before. Here is the realistic playbook.
The forecast
Use the JMA (Japan Meteorological Agency) sakura forecast, updated weekly from late January. Tenki.jp also runs a parallel public forecast that is sometimes earlier with revisions. Both predict kaika (first bloom, ~30% open) and mankai (full bloom, ~80% open) for each major city. Plan to visit 3–7 days after the predicted mankai date — the trees stay full for 5–7 days but lose petals to wind/rain.
Where to go (and when)
- Kyoto (Maruyama Park, Philosopher’s Path, Arashiyama) — late March to early April.
- Tokyo (Meguro river, Chidorigafuchi, Ueno Park) — late March to early April.
- Nara (Mount Yoshino, 30,000 trees) — early-to-mid April.
- Hirosaki (Aomori, castle moat) — late April to early May.
- Hakodate, Sapporo — early-to-mid May.
Hanami etiquette
Hanami means "flower viewing" but practically means "picnic under the trees with friends, beer, and combini food." Locals do this on weekends — bring a tarp or rent one at any combini, no reservation needed. Don't shake the branches for petals. Don't pick the blossoms. Don't bring loud music to a crowded park. Take your trash with you (no public bins).
Avoid the crowds
- Pre-dawn at the famous spots. Chidorigafuchi at 06:00 is empty. Same for Maruyama Park, Meguro river, Philosopher’s Path.
- Lesser cities at peak. Hirosaki, Takato (Nagano), and Yamazakura on Mount Yoshino get a fraction of Tokyo’s crowds at full bloom.
- The week after mankai. The petals fall in fubuki (blossom snowstorms) — fewer people, same magic.
- Skip Golden Week (29 Apr–5 May). Domestic crowds peak; book accommodation 6 months ahead or accept triple prices.
