Japan’s rainy season (tsuyu) puts many travelers off — but it has real upsides and is very manageable with a little planning. Here’s what to expect and how to make the most of it.
When is the rainy season?
Tsuyu typically runs from early June to mid/late July across most of Japan (Okinawa earlier; Hokkaido largely skips it). Expect humid days with periods of rain rather than constant downpours.
The upsides
- Fewer crowds and lower prices at big sights and hotels.
- Lush greenery — gardens and moss temples look their best; see our gardens guide.
- Hydrangeas (ajisai) bloom beautifully at temples and parks.
How to plan around the rain
- Mix indoor and outdoor plans — museums, aquariums, teamLab, shopping, and food halls are perfect rain backups.
- Carry a compact umbrella (cheap at any konbini) and quick-dry clothes; see what to wear.
- Check forecasts daily and stay flexible — with an eSIM you can adjust on the go.
What to know
- It’s humid — pack breathable clothing and a hand towel.
- Rain rarely ruins a trip here; trains and indoor life carry on as normal.
- Onsen towns are lovely in the rain — see our onsen towns guide.
Bottom line
If you don’t mind some rain, tsuyu offers value and beauty with fewer crowds. Compare with our best time to visit guide, and plan with a flexible itinerary.
