50 Best Things to Do in Japan in Summer (2023)

If you’re wondering what to do in Japan in summer, you’ve come to the right place! We happen to think Japan is the best year-round destination. You’ll have a different experience based on the areas of Japan you explore. With the incredible train system, you could be on one of the beautiful beaches and then hiking a mountain an hour later.

So what is there to do? Enjoy summer festivals in the major cities, beautiful train rides through the countryside, sunny days on a beach, incredible amusement parks, and so much more. Of course, if you enjoy hiking, there’s no shortage of mountains to climb in Japan! In this post, we’ll give you ideas to help you plan your summer vacation in Japan!

How Hot Does It Get in Japan in Summer?

We know there are lists out there about the best time to visit Japan (we even have one — it needs updating!), but they aren’t entirely accurate. The truth is that Japan has distinct seasons and they all have their pros and cons. You could face heavy rain and high temperatures, and you’ll encounter fewer tourists in the winter, but there’s nothing like Japan in summer!

Admittedly, you’ll see cooler temperatures and better weather during cherry blossom season in April before the rainy season from early June through mid-July. Summer in Japan is very hot and humid, but there’s so much great stuff to do. Still, if you’re going to venture out in the heat, it’s a good idea to get prepared for what to expect during this time of year.

Average Temperature in Japan Summer Months

While Japan may be a relatively small island, what you experience in northern Hokkaido will be very different from what you feel in Okinawa. As a result, there’s no easy way to describe what to expect in Japan in summer. 

What’s the hottest time of year in Japan? From late June to mid-September. For Tokyo and many major cities, the hottest month is August. It is brutal. With high temperatures and humid conditions, it can feel like you’re living in a sauna. 

Those rainy days from early June to early July add to the summer heat and make things miserable sometimes. Many feel that Japan’s humid summers are unbearable and the average high has only gotten hotter in recent years. 

Tips for Staying Healthy

As mentioned, you can experience extreme heat in Japan in summer, and you definitely want to avoid heat stroke. Here are some quick tips for staying safe in Japan’s heat.

  • Stay hydrated. Choose drinks like water, Pocari Sweat, and Aquarius.
  • Watch the forecast. If they issue a heat warning, consider staying indoors.
  • Choose early mornings. Plan to do your outdoor activities as early as possible and then spend the afternoon indoors. 
  • Wear sunscreen and a hat. Protect your skin from the sun!
  • Find shade. At many matsuri, or festivals, there’s no shade so keep that in mind.
  • Head to the mountains. You’ll usually find cooler temperatures.
  • Wear light-colored long sleeves to protect your skin. 

Locals also tend to rely on a few items to help beat the heat. We’d recommend the following but somethings all of these items together aren’t enough to prevent heat illness.

Gonna keep it real. We went to a festival for Marine Day in Chigasaki. The crowd was massive and since it was on the beach there was no shade. My daughter and I both suffered from heat exhaustion or heat stroke and had to receive medical attention. Just look at us in that photo 🙁 We love the annual events in Japan, but your health really needs to come first!

A Word on Natural Disasters

It’s not a myth. Japan is really, really prone to natural disasters. ALL kinds of natural disasters. Earthquakes, typhoons, tsunamis, landslides? We got ‘em! So, if you’re new to visiting Japan, please make an effort to be prepared and vigilant. 

It’s a really good idea to keep your eyes on the weather forecast. The weather conditions can change rapidly here, but the Japan Meteorological Agency really does a good job of trying to keep us ahead of problems. 

Typhoon season is basically summer in Japan. It runs from May to October, but August and September are the peak season. Heads up — the later in the year they are, the stronger the typhoons seem to be. 

What to Do in Japan in Summer

We have guides for June and July with August and September on the way. In the meantime, here’s a quick overview of what to do in Japan in summer (spoiler — there’s a LOT!). 

Collect Goshuin

Ever since arriving in Japan, one of my favorite hobbies is collecting goshuin. People love collecting things in Japan (that’s probably how Pokémon became some popular!), which is probably one reason why you can find these calligraphy stamps at shrines and temples. The word “goshuin” translates to “honorable red seal” or “red temple seal.”

These beautiful stamps are considered sacred and should be obtained and collected with respect. You’ll need a goshuincho, a special book designed for these stamps, to keep them safe. You can buy them online and at bookstores, but I prefer to buy them at a favorite shrine or temple.

When you visit, there is typically a booth with a window where you can buy charms, amulets, and similar items. Look for a sign with these characters to get your goshuin: 御朱印. It’s a really lovely memento and token of your visit. Be sure to check for any unique stamps designed for specific holidays and/or events.

Look for Eki Stamps

As you make your way across Japan, look for “eki stamps” or “eki inshu.” These collectible ink stamps are free and usually located near ticket gates or station offices at train stations. It’s a cool way to remember and commemorate a visit to a particular station or prefecture.

Often, you will find paper near the stamps but they can run out. Plus, it’s a pain to try to keep track of a bunch of loose pieces of paper. Get a notebook or stamp book (“shuinchō” or “inshu-chō”) where you can imprint the station stamps. Just please don’t put them in your goshuin book!

Visit a Famous Park

We always see Japan depicted as an electronic playground filled with neon lights and high-tech robots, but this country is FILLED with amazing natural landscapes. Check out the local parks in your area and let that forest bathing melt the stress away!

Honestly, we love food in Japan year-round but summer food here is just so refreshing and so much fun to enjoy. Definitely try something new to beat the heat!

Go to an Amusement Park
