What To Wear In Japan In Summer – The Ultimate CheckList


Travelers keep spreading rumors about not going to Japan in summer. It is unbearable! Too hot, too humid to be able to enjoy. Yes, during wet days, walking 30 minutes in the sun will soon get you drenched in a sweaty and uncomfortable situation.

On the other hand, it’s also the time for top festivals, mountain hikes, watching fireworks and enjoying seasonal flavors with a cold beer on a city rooftop. There is just too much temptation to resist!

So, if you are considering visiting Japan during this season, forget all the hype about bad weather. Seriously, how bad can it be? We will find out the truth in this article and give you the complete checklist on what to wear in Japan in summer so that you can beat the heat and enjoy a lively summer adventure.

The Truth About Summer Weather In Japan


Summer in Japan is not only one hot and humid mess but also the season of lush green scenery and good vibes activities at the same time.


Summer in Japan kicks off from June lasting through August. Temperatures can range approximately between 21°C (70°F) and 32°C (90°F). It can be incredibly humid as this is also when the monsoon rains hit.

However, in general, Japanese summer days are mostly sunny, not blisteringly hot, and rain tends to fall for only a few hours in the afternoon. Summer here maybe does not have the most pleasant weather, but certainly not unbearable. For your consideration, we will look briefly at Japan’s climate information monthly in summer.

Weather in Japan in June

Hello June, and here comes the Tsuyu, or rainy season in Japan. Compared to other summer months, June can be nice. It does not rain every day, still, the weather is usually overcast and dreary. During this time, the average daytime temperature in Tokyo is about 22℃, or 71.6℉.

Weather in Japan in July

The rainy season continues until around the last week of July. Rainfall remains high with an average of twenty rainy days and rain is often sporadic and heavy – making July the wettest months. Rain or shine, July is hot for the most part, and you can feel the summer heat outdoors. In Tokyo, Japan, during July, the average high-temperature is 29.2°C (84.6°F), and the average low-temperature is 21.8°C (71.2°F).

Weather in Japan in August

August, August, August. This month is definitely notorious for being the hottest month in Japan. The average temperatures are similar to July’s but typically are a couple of degrees warmer overall. You’ll also find the same numbers in tropical areas, such as Thailand’s Bangkok.

Notes: The weather also depends on where you go like north or south in Japan. It is calmer in the north part of Japan such as the Hokkaido and Tohoku Region and much hotter in the south like Okinawa and Kyushu Region. The heat can feel more intense in the cities than in rural areas, as well.

What to wear in Japan in summer

Obviously, summer is the hottest period of the year, and it even stays hot at night. Given the incredible humidity, light-weight quick-drying clothing made of cotton is the best bet. You can still put on some layers to create a stylish look. But make sure that your skin can breathe. All following pieces can satisfy these criteria, and we call them must-have items in Japanese summer fashion:

1.     Loose top


These tops keep things nice and cool without exposing too much skin.

It can be whatever you’d like, t-shirts or blouses. The baggier, the breezier. If you don’t mind some disapproving looks from locals, even crop tops, spaghetti strap tank tops or low cut tops are fine. But were you to follow the crowd, then wearing these types of tops is usually saved for late-night attire.

Even with men? Yes, men’s tank tops are especially uncommon in Japan, so you may turn some heads if you decide to show off your arms. A solution is to keep a light, thin UV-treated shirt or sweater with triple uses. It prevents you from UV rays, from feeling chilly in air-conditioned rooms/ trains. And when you go outside, drape it covering around your shoulders. Still such a chic touch!

2.     Comfortable Pants 


Japanese is opting for silhouettes, wide, baggy pants that’ are both stylish and practical.

Similar to the oversized blouses and t-shirts, wide-leg full-length pants are very trendy in Japan. They are an excellent summer-friendly option if you’re nervous about showing off tattoos or appearing disrespectful while visiting shrines and temples. Facts: In Japan, tattoos are associated with the mafia, and are banned in many places – even a tiny mark may mean you are refused entry.

Besides, pairing a loose top and comfortable pants will prevent you from sweating and feeling stuffy. Whether this cool outfit is coordinated in light or dark colors, it is surprisingly fashionable.

What about comfortable shorts? Don’t wear shorts that resemble pajamas (sweatpants or basketball shorts) or that are so loose that your underwear peaks through.

3.     Thin outerwear


Slip around thin outerwear for sun protection or if you feel cold indoors.

You may say “Outerwear appears in the list of what to wear in Japan in summer?”. Yes, it does. As mentioned above, in the summer, air conditioning will be at full blast in indoor venues, making it somewhat chilly. However, the oppressive heat outside makes it hard to regulate body temperature, which can cause you to catch a cold. That’s why we recommend wearing a thin jacket or cardigan. Dressing in layers that are easy to take on and off is a good idea, isn’t it?

4.     Sandals/ Slip-on shoes


We can’t emphasize enough the need for proper sandals or well broken-in walking shoes in Japan.

Walking shoes are a must when you visit Japan as you’ll be possibly walking all day. Even in well-connected cities like Tokyo, Kyoto and Osaka, the fastest, cheapest and best way to explore is by foot, especially in summer when the trains are packed with hot, sweaty commuters. Pack a pair of semi-casual shoes, and leave the flip flops at home!

Flip flops are not only uncomfortable to walk in all day but are also indecent in Japanese society. Proper sandals are the preferred choice if you want to wear open-toed shoes. But I wouldn’t suggest bringing these since they don’t support your feet at all. A pair of supportive, light shoes is a much more worthwhile investment.

Because you’ll find yourself stepping in and out of your shoes a lot in Japan, it’s worth it to bring shoes that don’t require lacing up. Visiting temples, homes, inns and even restaurants will require you to take off your shoes. You’ll regret life while you’re sitting down lacing up for five minutes in the doorway while people are trying to get in and out! Facts: if you see “tatami mats” on the floor, that means you should remove your shoes.

5.     Slipper


Prepare your own slipper if you dislike using a public one

You can not miss a pair of slides on the list of what to wear in Japan in summer. It is not only a good idea if you plan to go to the beach (of which Japan has plenty, and they’re incredible), but they’re also handy because regular shoes are a no-go in the house or the occasional public spaces (mentioned above).

Of course, most places that require you to leave your shoes will have public slippers that you can borrow; however, if you’re not too sold on the idea of wearing a pair of old communal slippers, it’s best to bring your own.

6.     Hat


Typically summer must-have items in anywhere

While Japan doesn’t have a reputation for the harsh sun, sunburn is possible (take it from someone who has experienced it first-hand), so make sure you pack a cap or a sunhat and take it out with you. Bonus points if your hat is packable.

7.     Yukata


The yukata is loose, easy to wear and comes in an endless selection of fashionable prints.

If you want to fit in with the festival crowd, consider picking up a Yukata: a summery light cotton version of a Kimono worn by both men and women. These days, Yukata is Japan’s most versatile garment loved by locals young and old. It looks sleek and requires minimal upkeep while staying cool, breathable in the hot weather, and easier to wash compared to the traditional silk Kimono.

What’s great about this piece of clothing is that it can be as basic or as extravagant as you like and it’s the perfect outfit during summer events like Hanabi (fireworks) festivals or when visiting onsen resorts.

In terms of essentials, Yukata are usually worn with simple underwear, and Koshihimo or ribbons to tie the yukata comfortably. On top of that, you’ll need an Obi or some sort of belt. You’ll want to wear some Geta (wooden sandal) too if you’re leaving the house. Besides, there is no need for Tabi socks or any extra layers. It is as simple as wrapping it around yourself like a bathrobe.


Yukata is worn with Koshihimo, Obi and Geta. That’s the basics.

The price of a Yukata depends on how much you want to pay for it! The most expensive Yukata can cost up to 1000 USD. On the other hand, it can be also very affordable – Uniqlo sells yukata for about 2,000 to 6,000 yen (18 USD -54 USD).

8. Rain Coat or Umbrela

To protect yourself from the rain, wear a thin, durable jacket that reaches mid-thigh or your knees like a traditional trench. However, it’s acceptable if the thought of donning anything with sleeves makes you queasy. Use a reliable umbrella to stay dry.

9. A waterproof bag

Save your adorable suede handbag for your subsequent summer vacation and get a waterproof bag to protect your belongings from the elements (pretty much anything faux should work great).

How to arrange clothes for each month of June, July, and August

1. June – The First Month of Summer and The Rainy Season

Although Vietnam’s climate has reached more than 30 degrees in June, the early summer days in Japan are not so hot. The temperature in the morning and evening is around 20 degrees, like Hanoi’s spring climate.

Therefore, a short-sleeved shirt with a thin jacket and trousers or a long skirt is an appropriate choice for the first days of summer. Although the south and north of Japan are different, in Tokyo, for example, as long as you prepare an umbrella and sandals for the rainy season in June, there will be no problem for your trip.

2. July – The Month of Festivals and Fireworks

July is the beginning of an exciting summer with the Niu Lang – Chuc Nu festival (July 7 of the solar calendar), a summer festival, and a fireworks festival. This is a hot and humid time. You need to prepare clothes with summer style and avoid the sun.

Because the summer heat of Japan is not inferior to Vietnam, you should not take it lightly. We need to pay attention to things like avoiding the harsh rays of the sun at noon, drinking water for the body, and being careful not to get summer heat.

If you wear a yukata to the festival, don’t forget to bring a paper fan with you!

3. August – Hot and Humid Summer Days

Along with the intense, humid heat, August enters the peak of summer. This is also the time of the Obon holiday – also known as the Vu Lan festival of Japan (The festival usually takes place from August 13 to 15). Clothing is mainly made of airy materials and sun protection like July.

July and August (depending on where September is also included) is typhoon season in Japan, so you also need to prepare rain storm protection gear like a raincoat or jacket. During the coming storm, sometimes the tram lines bordering the sea will be temporarily suspended, so when traveling, please pay attention!

Clothing Tips for Summer

  • Cotton, linen, and rayon are the best materials for keeping cool and comfortable in Japan’s often-sweltering summers.
  • In a similar vein, wearing light-colored clothing that reflects the sun helps keep you feeling energized.
  • An excellent choice is to wear loose-fitting clothing because it lets the breeze pass through while keeping you cool.
  • In the summer, the sun may be very powerful in Japan. Locals can be seen wearing hats with wide brims to shield their skin from the sun.
  • Sunglasses and sunscreen are necessary, as well as cooling items like neck wraps, bandanas, and scarves.
  • The summer is the ideal time to wear your favorite sandals or cozy sneakers. Shoes and boots that are too hefty might cause your feet to become overheated and perspire.
  • It’s a good idea to pack a lightweight raincoat or umbrella in the summer because storms might come at any time.
  • Drink a lot of water when sightseeing.

What to Avoid Wearing?

Japan is a nation that takes pride in its sophistication and organization. If you wish to blend in when you visit the country, the same should be mirrored in your daily wardrobe decisions. Following are some taboos to steer clear of when visiting Japan:

1. Holes in socks

As you can expect, when inside, you’ll be removing your shoes rather frequently. In a nation like Japan that takes pride in cleanliness, having holes in your socks is unhygienic and unseemly. Pack some clean, recent socks for your trip.

2. Revealing clothing

Temples and shrines are revered locations. Maintaining cultural norms and customs requires modest attire. Avoid wearing items like shorts, tank tops, and miniskirts. Even if you don’t intend to visit temples or shrines, it’s still a good idea to dress more conservatively. Women are often discouraged from exposing their cleavage.

3. Clothing with offensive messages or designs

Wearing apparel with objectionable graphics or sentiments is best avoided, especially if they could be construed as racist or discriminating.

4. Tattoos

In Japan, tattoos are still linked to the Yakuza or mafia. If you wish to stay in onsens and ryokans, be sure to cover them with bandages. Even though they are becoming more and more popular, you must almost always keep them covered.

5. Swimwear

Swimwear is only appropriate for beaches and pools; it is never appropriate to wear it in public settings like streets or temples. Although there are a few exceptions, swimsuits are often prohibited in onsens as well.

6. Avoid dressed in all-black suits when conducting business

Funerals are typically the only occasion when someone would dress fully in black, including with a white shirt. Black ties should ideally be avoided because they are also connected to funeral attire.

7. Wearing too casual clothing

When visiting specific locations, including temples, shrines, and restaurants, it is considered rude to dress too casually. Japan is recognized for its fashion-conscious culture.


1. Does Japan allow the wearing of shorts?

Shorts wearing is not prohibited by Japanese law or custom. Due to the occasionally intense Asian heat, it is fairly typical to see other travelers wearing shorts in the major cities, especially in the summer.

2. What should I wear in July in Japan?

Choose airy slacks or skirts and thin, light clothing as July is the height of summer in Japan. However, we do advise taking a lightweight jacket and avoiding exposure to the sun during the day. At night, the temperature will drop to around 20°C/68°F, so take precautions to avoid getting sick.

3. What not to wear while visiting Japan?

Avoid wearing items like shorts, tank tops, and miniskirts. Even if you don’t intend to visit temples or shrines, it’s still a good idea to dress more conservatively. Women are often discouraged from exposing their cleavage. Merchandise featuring obscene text or graphics.

4. Which is better, June or July in Japan?

Many areas of the country experience high temperatures and humidity, but June is typically more bearable than late summer. June is a better season to visit Japan if you want to experience a Japanese summer than July or August, and if you know where to go, you may have a relaxing and pleasurable stay there in June.

5. What month is the hottest in Japan?

The hottest and most humid months are usually July and August, which might make sightseeing uncomfortable if you are sensitive to humidity. However, summer may also be one of the liveliest times to be in Japan, perhaps even in spite of the oppressive weather.

6. How severe are the clothing codes in Japan?

Japanese work dress relies on just wearing dark hues, with a neutral shirt and tie, in keeping with the culture’s ideas of “blending in.” Women should wear skirts, but they shouldn’t be too short or too tight. Pumps are OK, but a low heel has little benefit.

7. What is Japan’s most beautiful season?

The spring season (March to May) and the fall season (September to November) are the ideal times to visit Japan. Japan is at its most colorful during this time, with delicate cherry blossoms or vivid red leaves providing contrast to the surroundings.

8. Why do Japanese schoolgirls wear short skirts?

They dress in a miniskirt because they believe it to be a privilege while they are still young. All of this may be founded on the notion that Japanese people are concerned about how others perceive them. People care about their appearance for this reason.

9. Why do most Japanese women have short hair?

The short hairdo is designed to draw attention to how little one’s face is. Most girls want the innocent, charming appearance that this type of hairdo conveys. However, other people like to wear their hair in far funkier ways.

10. Can you wear leggings in Japan?

Sadly, in Japan, wearing tracksuit bottoms or leggings outside of the gym is frowned upon and seen as sloppy. Women are required to dress professionally and subtly at work, typically in the same hues as men.

11. What is the skirt policy in Japan?

Most people feel that the “best” skirt length is 15 cm above the knee; this length is the perfect balance of long and short. However, some schools have policies stating that skirts must be long.

12. Is wearing purple acceptable in Japan?

For a very long time, it was against the law for regular people to wear purple clothing in Japan. Murasaki, meaning purple in Japanese, used to be quite uncommon because it took so long and effort to manufacture.


Oh summer, hot hot summer in japan from June to August with heavy rainfall, turns the country into a steam bath. Make sure to bring these above must-have items together with some extra clothes to change into when the first outfit gets sweaty and you’ll be fine.

When deciding what to wear in japan in summer, remember that the Japanese dress code is relatively conservative on the whole. If you plan to make an excursion to a temple or traditional public places, you should avoid wearing sleeveless tops or clothing that reveals certain areas of the body. Otherwise, you can definitely bring along something to cover up.

Lastly, it’s important to note that you should feel comfortable wearing whatever you’d like. You can still have that ‘fashionista’ vibe, dressed in the craziest (but undeniably fun) Harajuku outfits, which is super common to the Japanese younger generation. It is up to you whether to follow the rules or make outlandish fashion statements.

I hope this list helps you to worry less about what to wear in Japan in the summer and spend more time enjoying these wonderful summertime experiences!
