How To Beat Japan Summer Heat: What You Need

In this post, we will discuss the basics of planning a trip to Japan in Summer, tips for navigating the process, and items you can consider buying to help you!

While Japan’s heat can be hard to handle, there are also some fantastic things to do in Japan during the summer.

Summer in Japan means Matsuri (festivals), fireworks, hiking Mt. Fuji season, and a lot of unique events that make a vacation in Summer unforgettable, if you feel brave enough to endure the heat!

It can feel quite long from June to the end of September (and even some October days felt like summer to me as a European last year!).

This post is a great way to plan for the Japanese summer. I also have a separate post if you want to know more about what you should know before visiting Japan.

How Hot Is Japan Summer?

Of course, this will vary significantly depending on where you are in Japan; whether you’re in Hokkaido, Okinawa, or Tokyo will not be the same. It’s hot all around, but it feels better if you’re in nature instead of a city.

But you should expect temperatures to easily soar above 30°C (86°F) but with the constant humidity it quickly feels like 40° (104°F).

Summer in Japan is scorching. Last year (2024) has reached its hottest year for July, and August only got hotter. If you’re not used to the heat and do not handle it well, I would reconsider visiting Japan in the summer.

But if you don’t have a choice of vacation dates, you have found the perfect post to help you cope with the Japanese summer heat!

What To Wear In Japan in Summer?

Pack linen clothes; they are great for coping with the heat. Tight clothes should also be avoided if you can; I noticed it quickly feels like a swamp of sweat in those.

You should also consider the Keep Cool line from UNIQLO!

You can wear whatever outfit you want; I know a lot of people are saying “Oh, Japan is so modest, don’t wear this, don’t wear that” and while it of course has some truth to it I’ve also seen plenty of very short outfits from locals so take this as you wish… So, if you want to wear a regular tank top and shorts, go for it; no one will bat an eye as long as you’re respectful and aware of your surroundings.

Tips To Survive Japan Summer

Keeps Your Expectations in Check

Japan’s summer heat can be intense, so it’s perfectly okay to slow down your pace. You might not be able to check off every item on your itinerary, and that’s totally fine.

You’ll get tired, you’ll need breaks, and you might not be able to do everything on your bucket list, and that’s fine. You can’t expect to walk around 3 neighbourhoods during the same day and not take any breaks.

Prioritise comfort and health over cramming in activities—sometimes, enjoying a slower day with fewer plans is the best way to truly experience the season without overheating or burning out.

Visit Water/Nature places

Plenty of places are close to bodies of water and fantastic nature spots well within Tokyo (the prefecture of Tokyo is very vast, after all!).

Here are a few spots I recommend you visit in Tokyo

Mt Takao
Mt Mitake/ Mitake Gorge
Rinkai Kasai Park
Todoroki Gorge

There are also plenty of amazing gardens within Tokyo, but while beautiful, they can still be very hot.

Day Trip ideas from Tokyo to escape the heat of the concrete jungle of Tokyo:

Kamakura/Enoshima
Hakone
Nikko
Ibaraki

But if you truly want to escape the heat a little bit more you should consider planning a trip to Hokkaido!

This is what my friend and I did last summer and it was an amazing decision while it was still hot it felt so much nicer than Tokyo.

Beach Destinations In Japan For Summer

If you’re more of a beach person and are longing to spend your day near the water while still enjoying Japan here are some destinations you should consider:

Okinawa Main Island – Crystal-clear waters, white sand beaches like Emerald Beach and Zanpa Beach, and vibrant coral reefs perfect for snorkeling and diving.
Ishigaki Island (Okinawa Prefecture) – Famous for Kabira Bay and snorkeling with manta rays. A tropical paradise with a more relaxed vibe than the main Okinawa island.
Miyako Island (Okinawa Prefecture) – Known for some of Japan’s best beaches like Yonaha Maehama and Sunayama Beach. Calm turquoise waters ideal for swimming and water sports.
Amami Oshima (Kagoshima Prefecture) – Lush nature, secluded beaches like Ohama Seaside Park, and a great spot for kayaking, snorkeling, and relaxing in a less-touristy setting.
Shirahama Beach (Wakayama Prefecture) – A popular beach resort area on Honshu, known for its white sand and nearby hot springs.
Zushi Beach (Kanagawa Prefecture) – Close to Tokyo and Yokohama, this beach offers a fun summer vibe with views of Mount Fuji on clear days and a laid-back local feel.
Kamakura Yuigahama Beach (Kanagawa Prefecture) – Easily accessible from Tokyo, it’s a good spot to enjoy the sea after temple-hopping in Kamakura.
Kujukuri Beach (Chiba Prefecture) – One of Japan’s longest beaches, great for surfing and beach walks, and a peaceful alternative to the crowded urban beaches.
Tottori Sand Dunes Beach (Tottori Prefecture) – A unique beach experience beside Japan’s famous sand dunes, offering a desert-meets-sea atmosphere.
Niijima Island (Tokyo’s Izu Islands) – Reachable by ferry from Tokyo, Niijima offers beautiful beaches like Habushiura, known for surfing and clear blue waters without huge crowds.

Plan Indoor Activities

When the heat becomes overwhelming, it’s a great time to explore Japan’s many indoor attractions. Museums, aquariums, temples, shopping malls, and even themed cafes offer a cool escape from the sun while still letting you experience local culture. You can also take advantage of Japan’s excellent public transportation to hop between air-conditioned spots without too much time outdoors. Mixing in indoor activities will help you stay comfortable and make the most of your summer trip.

Allow breaks

Don’t underestimate how quickly the heat and humidity in Japan can drain your energy. Make sure to schedule regular breaks in shaded areas or air-conditioned spots like convenience stores, cafes, or shopping centers.

Even a few minutes of rest can help your body cool down and prevent heat exhaustion, especially if you’re walking around or sightseeing.

Items to Help You Cool Off During Japan Summer

The good thing about Japan is that you can get plenty of items and knick-knacks to help you survive the Japanese summer the minute you land there. Trust me, some of those items can help make your trip a lot better!

Those items are readily available. Most stores display all their summer items as soon as it gets hot, so you can’t miss them.

Here is a list of shops you can check out to find those items:

Matsumoto Kiyoshi
Daiso
Threepy
Donki
Sundrug
Loft
Tokyu Hands

You can also check specific shops to find more fancy or themed items, like a Rilakkuma or Pokemon.

Sunscreen Is A Must

This is a common sense precaution, applicable anywhere in the world on warm, sunny days, but make sure to wear sunscreen.

So don’t forget to apply sunscreen before heading out; Japan’s summer sun can be intense, and UV rays are strong even on cloudy days.

Look for lightweight, sweat-resistant formulas that won’t feel sticky in the heat. Japanese sunscreens are renowned for their high quality and comfortable texture (for example, Bioré is excellent), so it’s also a great opportunity to try some local favourites.

Reapply throughout the day, especially if you’re walking around a lot or spending time at the beach.

Cooling Neck Rings

You will quickly notice that many Japanese people wear these cooling neck rings during the summer.

These handy accessories have become increasingly popular in Japan during the summer—and for good reason.

Cooling neck rings are reusable, wearable ice packs that help regulate your body temperature by keeping your neck cool. They’re lightweight, easy to use, and can stay cold for a surprisingly long time without melting all over you.

You’ll find them in convenience stores and drugstores.

Hand Fan

A hand fan is the staple of the Japanese summer survival kit.

A classic and practical way to beat the heat in Japan is by carrying a hand fan. Whether you go for a traditional sensu (folding fan) or a modern battery-powered mini fan, it’s a simple yet effective way to stay cool on the go.

You’ll see locals using them on trains, in parks, and while walking around the city.

They’re lightweight, easy to carry, and often come in cute or stylish designs, making them both functional and a nice souvenir.

Cooling Wipes

Cooling wipes are a summer essential in Japan, particularly when the heat and humidity become overwhelming.

These refreshing wipes are infused with menthol or cooling ingredients that leave your skin feeling instantly cooler and cleaner, I’ve got the pokemon ones as I am sucker for a cute packaging and they saved me plenty of times.

They’re perfect for wiping down your neck, arms, or face after walking around in the sun and ideal to keep in your bag while exploring.

A little bit less ideal when you’re wearing make up though, but it’s not the nicest to wear make up in Japan during summer anyway.

Cooling Mist

A refreshing and instant way to beat the heat, cooling mists are a must-have during Japan’s hot summer months.

These portable sprays provide a burst of cool, hydrating mist that helps lower your body temperature while refreshing your skin.

Many are infused with soothing ingredients like aloe vera or rose water, offering a calming effect on the skin after a long day in the sun.

They’re compact enough to keep in your bag or pocket, making them ideal for quick relief while sightseeing or waiting in line.

UV Protecting Umbrellas

You’ll see so many people walking around with umbrellas in the summer (or on any sunny day, to be fair). These are a great way to have some shade when you walk around. They also protect you from the sun’s UV rays, which is always a plus.

I haven’t gotten around to getting one, but friends always recommend it to me, but I can’t bother holding one all the time.

Fan Jacket

This is a little bit extra but if you want to take it further, you should get a fan jacket!

I’ve seen them plenty of times, and if you’re also online and watching Japanese content, you’ve undoubtedly seen them, too!

That’s a wrap on this guide on coping with the Japanese Summer heat! I hope this post has helped you prepare for your trip to Japan. All that is left to do is enjoy your trip to the max.

As I mentioned in the post, while Japan is hot and humid in the summer, it is still an amazing time to visit, with all the Matsuri (festivals), fireworks, and summer events.

These are all amazing experiences that will make your Japan summer trip unforgettable, despite the heat.
