Rainy Season in Japan: It’s Here Again
It’s raining again.
Or maybe it isn’t, depending on the hour. That’s how it is during rainy season in Japan.
As I write this, it’s humid enough to feel like the walls are sweating. The kind of humidity where your clothes feel a little damp even though you haven’t been out in the rain at all. It clings to you. Not in a poetic way. In a real, sticky, everyday way.
But that’s all part and parcel of being in Japan. It has distinct seasons, as Japanese people love to point. Let’s appreciate all of Japan’s seasons (‘cause hey, what other choice is there).
What Does Rainy Season Really Feel Like?
Rainy season doesn’t mean it rains all day every day.
It just means that it could.
You start checking the forecast more often. You carry an umbrella even when it looks fine in the morning because there’s a good chance the skies will change their mind by lunch.
Most Japanese people (and local non-Japanese residents, like myself) do exactly that. The umbrella becomes part of your daily setup. Bag, phone, keys, umbrella.
Rainy Season as a Visitor to Japan
If you’re visiting Japan in rainy season, it’s a good idea to do as the locals do.
A lot of hotels here provide umbrellas, either in your room or down in the lobby. They’re there for you to borrow and return.
Convenience stores (konbini) are another easy option. Most carry clear plastic umbrellas that cost just a few hundred yen. You can also find better quality ones at department stores or supermarkets if you want something sturdier or longer-lasting.
What really sets this season apart though isn’t the rain itself. It’s the way the weather feels. Especially if you’re spending your days out exploring, which most visitors are.
Even folks who come from humid places like Florida or Texas, India or Southeast Asia, often mention that it the humidity hits differently in Japan.
That might be because you’re walking more. Climbing stairs at train stations. Going through shrine paths, city streets, markets. The movement makes the heat and humidity feel heavier.
How Japan’s Rainy Season Compares to Other Places
| Location | Seasonal Timing | Weather Characteristics | Traveler Experience |
|---|---|---|---|
| Japan (Honshu) | June to mid-July | High humidity, intermittent rain, warm | Manageable with an umbrella, still good for sightseeing |
| Thailand | May to October | Heavy monsoon rain, short sunny breaks | More intense rain but lots of indoor activity options |
| Florida (USA) | June to September | Hot, humid, frequent afternoon thunderstorms | Similar feel, though more sudden downpours than in Japan |
| United Kingdom | All year, especially autumn and winter | Light drizzle, cool temperatures, gray skies | Less humid, but more persistent overcast and dampness |
| Vietnam (Hanoi) | May to September | Very humid, heavy rainfall, high temperatures | Rainy days can be intense, planning around storms is common |
Tips for Travelers During Japan’s Rainy Season
And this is only the beginning.
The heat in Japan will come later, and it will be intense.
But June is when the adjustment period starts - especially if you’re visiting Japan’s Golden Route of Tokyo-Kyoto-Osaka.
You go from crisp spring days to the slow buildup of moisture in the air. Things start to smell a little earthier. The pavement stays wet longer. Shoes take longer to dry. Laundry too.
The air feels thick.
Still, there’s something about it I’ve come to expect and even appreciate in a way.
The sound of rain outside the window. That moment when the clouds part and the sun comes out for a few hours. The umbrellas propped outside every doorway. It’s all part of life in Japan.
The shift from season to season doesn’t always look dramatic, but you feel it.
So if you’re packing for Japan this time of year?
bring light clothes
wear shoes that can get wet
and rely on an umbrella (you may not need it every day, but odds are you’ll be glad to have it when the sky suddenly opens up)
The rainy season in Japan also has a way of forcing visitors to Japan to slow down a bit. And when it comes to Japan trips, that’s often a good thing.
Those slower travel times are often when you find some of the best moments on your trip!

FAQ: Rainy Season in Japan
-
No, it doesn’t rain every single day, but you should always be prepared for sudden weather changes. During rainy season, the forecast might show sun in the morning and then turn to clouds and showers by the afternoon. It’s common to have a mix of drizzle, short downpours, and even a few completely dry days. If you’re planning to be out all day, it’s smart to carry a lightweight umbrella with you, just in case. Unlike monsoon seasons in some countries, Japan's rainy season tends to be more moderate but persistent.
-
The key to packing for Japan in June and early July is light layers and moisture-friendly clothing. You’ll want breathable fabrics because the humidity makes everything feel heavier. Quick-dry shirts, shorts or light pants, and waterproof shoes or sandals are great options. Don’t forget a compact umbrella or a packable rain poncho. Some travelers also bring a small towel or handkerchief, which is actually very common in Japan. You’ll see locals use them to wipe off sweat or dry their hands since public restrooms often don’t have paper towels.
-
Yes, you absolutely can. Japan is built to handle rain. Many cities have covered shopping arcades, underground walkways, and sheltered entrances. If the weather turns, it’s easy to shift from a walking tour to a museum, a food market, or a hot spring bath. The countryside, temples, and gardens can actually look even more beautiful when everything is glistening with rain. The moss grows greener, the hydrangeas bloom, and the crowds tend to be a little smaller. Just allow a bit more flexibility in your daily plans so you can move things around if needed.
-
Yes, they’re incredibly easy to find, even on short notice. Convenience stores (like 7-Eleven, Lawson, or FamilyMart) sell clear plastic umbrellas near the entrance. You don’t need to speak Japanese to buy one. Some cost just 300 yen, and they’re surprisingly durable. Hotels often offer free loaner umbrellas, either in the room or in baskets by the front desk. If you prefer something stronger or more stylish, head to a department store or even a 100 yen shop. The cultural norm in Japan is to be prepared for rain, so umbrellas are everywhere.
-
Japan’s rainy season usually starts in early June and ends around the middle or end of July, depending on the region. In Tokyo, for example, the rain often begins the first or second week of June and tapers off before the start of summer vacation. In Kyoto and Osaka, the pattern is similar. Okinawa starts and ends earlier, while Hokkaido barely gets a rainy season at all. The transition out of rainy season leads straight into full summer heat, so this period also marks the rise in humidity and the gradual shift into Japan’s hot season.
