日本の梅雨は6月上旬から7月中旬。実は最悪じゃない — 紫陽花シーズン、ホテル30%オフ、北海道は梅雨なし。
Foreigners cancel Japan trips because of 'rainy season'. It's actually one of the best times to visit — hydrangea season, hotels 30% cheaper, and 2 regions skip tsuyu entirely.
2026 tsuyu (rainy season) dates by region
| Region | Start (typical) | End (typical) | Rainy days |
|---|---|---|---|
| Okinawa | May 10 | June 20 | 20 days |
| Kyushu (Fukuoka, Kumamoto) | June 5 | July 15 | 22 days |
| Kansai (Osaka, Kyoto) | June 8 | July 18 | 18 days |
| Kanto (Tokyo) | June 10 | July 22 | 17 days |
| Tohoku (Sendai) | June 15 | July 28 | 15 days |
| Hokkaido | NO TSUYU | - | 3-5 total rainy days June-July |
🎯Hokkaido escape hack
Hokkaido doesn't have tsuyu. If you must visit Japan in June, fly directly to SapporoPR. Lavender in Furano peaks late June-early July, weather is 20-25°C, and hotels are cheap.
Why tsuyu isn't actually bad
- ●Not raining ALL DAY: usually 2-4 hours of rain per day; check weather app hourly
- ●Hydrangea (ajisai) season: temples covered in pink/purple/blue flowers, only during tsuyu
- ●30% cheaper hotels: shoulder season pricing
- ●Fewer [tour](https://www.klook.com/en-US/search/?query=Japan)ists: photograph landmarks without crowds
- ●Temps 22-27°C: warm but not the July-Aug heat inferno
- ●Fresher air: rain washes pollution
Best ajisai (hydrangea) viewing spots
- ●Meigetsu-in Temple, [Kamakura](https://www.booking.com/searchresults.html?ss=Kamakura) — 2500 blue hydrangeas, THE spot (June 10-25 peak)
- ●[Hakone](https://www.booking.com/searchresults.html?ss=Hakone) Tozan Railway — mountain train line covered in hydrangeas

- ●Toshogu Shrine, Nikko — subtle, less crowded than KamakuraPR
- ●[Kamakura](https://www.booking.com/searchresults.html?ss=Kamakura)'s Hasedera Temple — hillside covered in hydrangeas
Best indoor activities for rainy days

What to pack for tsuyu
- ●Umbrella: buy at 7-Eleven ¥600, don't bring your own
- ●Waterproof shoes: sneakers get wrecked; consider quick-dry travel shoes
- ●Waterproof daypack cover (or use plastic bag)
- ●Light rain jacket: packable, breathable
- ●Extra socks + shoe inserts: nothing worse than wet-feet all day
- ●Ziplock bags: for phone, camera, passport
