Rain in Japan comes in seasons. Early summer brings the long rainy season, known as tsuyu, and late summer and early autumn are typhoon season. The Japan Meteorological Agency publishes the start and end of the rainy season for each region every year, which is worth checking before you book.
In between, summer sun is strong enough that many people carry an umbrella on dry days too.
The picks
For the rainy season
Repel Windproof Travel Umbrella
Repel states nine fiberglass ribs, a Teflon-coated canopy and a lifetime replacement warranty. The coating helps in Japan specifically: you'll close your umbrella and put it in a stand or a plastic sleeve many times a day, and a canopy that sheds water drips less.
Know before you buy
- Repel doesn't publish a folded length, so check it against your bag.
- No single wind rating: Repel's own pages disagree, so there's no number to compare.
Maker's specs
- 9 resin-reinforced fiberglass ribs
- Teflon-coated canopy
- Automatic open and close
- Under 1 lb
- Lifetime replacement warranty

- Wind-tunnel tested to 45 mph
- 11.8 in folded, 0.85 lb
- 38 in open diameter, 42 in arc

Maker's specs
- 42 in double canopy
- Auto open and close button

Umbrella etiquette you'll see
Stands at the door. Shops, restaurants and temples often have umbrella stands outside. Leave yours there rather than carrying a dripping umbrella in.
Plastic sleeves. Some stores offer long plastic bags at the entrance for wet umbrellas. Use one if you keep your umbrella with you.
Make it recognizable. A stand full of black and clear umbrellas makes yours hard to find, and easy for someone else to take by mistake. A colored canopy or a tag helps.
Convenience stores sell umbrellas. If you forget yours, a convenience store umbrella will get you through a shower, though not through much wind.
Before you go
Ordering right before your flight? An Amazon Prime free trial (paid link) may get the umbrella to you sooner, depending on the item and your address.
Questions people ask
When is the rainy season in Japan?
It varies by region and year. The Japan Meteorological Agency announces the start and end dates for each region; check its site for the year you're traveling.
Do I need a sun umbrella in Japan?
For a summer trip, a canopy with a UPF rating is useful. Weatherman lists UPF 50+ for its Travel Umbrella, so one umbrella can cover both rain and sun.
Is it safe to use an umbrella in a typhoon?
No. When typhoon warnings are in effect, follow local guidance and stay indoors. No compact umbrella is meant for typhoon winds.
