Introduction
If you’re planning to travel to Japan in the summer, you might have heard of the term “Tsuyu” (梅雨), which refers to the country’s rainy season. But equally important is “Tsuyu-Ake” (梅雨明け) — the end of the rainy season. Understanding when and how this transition happens can help you make the most of your visit.
1. What Is Tsuyu (Japan’s Rainy Season)?
Tsuyu typically begins in early June and lasts until mid-to-late July, depending on the region. It brings consistent rain, high humidity, and overcast skies. The rainy season is essential for agriculture but can be a surprise for travelers unfamiliar with Japan’s climate.
2. What Does “Tsuyu-Ake” Mean?
“Tsuyu-Ake” means the official end of the rainy season. It is announced by the Japan Meteorological Agency (JMA) when weather patterns indicate a shift to stable, summer-like conditions. After Tsuyu-Ake, the weather turns hotter, sunnier, and generally drier — though occasional thunderstorms may still occur.
3. When Does the Rainy Season End in Different Regions?
| Region | Approx. End of Tsuyu |
|---|---|
| Okinawa | Late June |
| Kyushu | Mid to Late July |
| Kansai (Osaka) | Mid to Late July |
| Kanto (Tokyo) | Around July 19–24 |
| Tohoku | Late July to Early August |
| Hokkaido | No distinct rainy season |
Note: The actual dates vary slightly each year.
4. How Will Tsuyu-Ake Affect Your Trip?
- More Outdoor Activities: Clear skies and dry weather make it perfect for hiking, sightseeing, and festivals.
- Hotter Temperatures: Expect temperatures to rise above 30°C (86°F), especially in urban areas like Tokyo, Kyoto, and Osaka.
- Crowded Tourist Spots: Summer vacations begin for students and families after Tsuyu-Ake, leading to increased crowds.
- Wear Light, Breathable Clothing: Post-rainy season Japan is hot and humid. Stay hydrated and wear UV protection.
5. Recommended Places After Tsuyu-Ake
- Mt. Fuji: Official climbing season begins in July.
- Fireworks Festivals (Hanabi Taikai): Held all over Japan, especially in August.
- Beaches in Okinawa and Shonan: Perfect for sunbathing and swimming.
- Summer Festivals: Gion Matsuri in Kyoto, Awa Odori in Tokushima, and more.
6. Final Tips for Travelers
- Check the Weather Forecast Regularly. Even after Tsuyu, Japan can experience sudden thunderstorms.
- Book Early. Summer events and holidays increase hotel and train bookings.
- Protect Against Heatstroke. Use sun hats, handheld fans, and stay in shaded areas during midday.
