Some avoid it entirely, while others swear by the lush greenery and thinner crowds.
But how bad is the rainy season in Japan, really? Whether you’re wondering if October is still rainy or trying to pinpoint when the season ends in Tokyo, this comprehensive guide will prepare you for the 2026 forecast and help you find the best places to visit even when the skies turn gray.
🌦️ What Is the Rainy Season in Japan?
The Rainy Season in Japan is a seasonal weather phenomenon caused by the meeting of warm and cool air masses over East Asia. This creates a stationary rain front that brings frequent rainfall, high humidity, and cloudy skies across most of Japan.
Unlike the monsoon seasons in some countries, Japan’s rainy season is not constant heavy rain every day. Instead, it usually consists of intermittent showers, occasional downpours, and sometimes sunny breaks.

How Bad is the Rainy Season in Japan? (The Reality)
If you browse Japan rainy season Reddit threads, you’ll find two types of people: those who were miserable and those who had the time of their lives.
The Reality: It isn’t usually a month-long monsoon. Instead, Tsuyu is characterized by:
- Persistent Drizzle: Light, misty rain that can last for hours.
- High Humidity: The “muggy” feeling is often more challenging for tourists than the actual water.
- Gray Skies: Overcast weather is the norm, which actually makes for great, soft lighting for photography.
- Lush Nature: This is when Japan’s gardens and moss forests look their most vibrant.
Is it “bad”? Not if you’re prepared. Most Japanese cities are built to handle rain. Huge underground shopping malls, covered “Shotengai” (shopping arcades), and the ubiquitous $5 clear umbrellas from 7-Eleven make navigating the wet weather surprisingly easy.

Japan Rain by Month: Beyond the Official Season
A common point of confusion is whether the rain stops the moment Tsuyu ends. Here is a look at Japan’s rain by month to help you distinguish between the “Rainy Season” and the “Typhoon Season.”
Is September rainy season in Japan?
Technically, no. The official Tsuyu ends in July. However, September is part of the Typhoon Season. While June brings steady, light rain, September can bring intense, short-lived storms. Statistically, September is actually one of the wettest months in cities like Tokyo and Osaka due to these tropical cyclones.
Is October rainy season in Japan?
October is widely considered one of the best months to visit Japan. By early October, the typhoon risks diminish significantly, the humidity breaks, and the skies clear up. It is not considered a rainy season; rather, it is the beginning of the stable, crisp autumn weather.
When does Japan rainy season end?
For most of the main island (Honshu), the season concludes in late July. Once the “rainy season withdrawal” is announced by the Japan Meteorological Agency, the country transitions immediately into a brutal, scorching summer heat.

This sacred temple settlement in Wakayama is breathtaking in the rain. The towering cedar trees and moss-covered tombstones of Okunoin Cemetery feel even more ancient and spiritual when draped in fog.

If you truly want to avoid the rain, head north. Hokkaido is the only part of Japan unaffected by the rainy season. While the rest of the country is humid and wet, Hokkaido enjoys mild temperatures and clear skies—perfect for seeing the early lavender blooms in Furano.

Known as the city of rain, Kanazawa is prepared for it. The famous Kenrokuen Garden features “Yozuri” (snow/rain ropes) and looks incredible in the wet. Plus, the city’s Higashi Chaya district (geisha district) feels incredibly atmospheric under a traditional umbrella.

Survival Tips: What to Expect and Pack
To make the most of the rainy season in Japan, follow these local “pro tips” gathered from frequent travelers and residents:
- The “Konbini” Umbrella: Don’t pack a heavy umbrella. Buy a clear, plastic one at any convenience store for about 700 yen. They are sturdy, and because they are transparent, you can still see the city lights above you.
- Shoe Strategy: Waterproof sneakers or Gore-Tex boots are a lifesaver. Avoid flip-flops, as city streets can get slippery.
- Utilize Luggage Forwarding: Use Takkyubin (luggage forwarding services) to send your bags between hotels. Dragging a suitcase through a puddle to find your hotel is the quickest way to ruin a mood.
- Museum Days: Save your indoor activities—like the TeamLab Borderless in Tokyo or the Kyoto International Manga Museum—for the days with the heaviest 2026 forecast.
Summary: Should You Visit in 2026?
The rainy season in Japan is far from a travel deal-breaker. While you might miss out on a clear view of Mt. Fuji (which is often shy behind clouds in June), you gain the ability to see Japan’s nature at its most lush and vibrant.
If you prefer cooler weather and don’t mind carrying an umbrella, June is a fantastic time to visit. However, if you want guaranteed dry days and autumn colors, wait until October.
