Why is Kyoto known to be hotter during the summer?
With Kyoto being surrounded by mountains, the heat and moisture tend to make this space feel a few degrees hotter. Hokkaido tends to remain cooler during these months, with sun and breeze coming in from the sea current. Making this part of the country an ideal place for outdoor activities or lounging in the sun.

What to wear in July:

  • Loose, airy clothing
  • Shorts, skirts, t-shirts  (note some shrines/temples appreciate modest clothing)
  • Hat + sunglasses
  • SPF
Japan Summer Tip:  Temperatures often don’t drop much in the evenings, so it’s best to choose accommodation with air conditioning at this time of year.
 
Items to help your Summer in Japan, stress-free:
July can be considered a tough month to visit Japan. Here are a few items to consider packing or purchasing once you’re out there to stay cool:
  • Small portable fan.
  • Wipes, or cooling towels
  • Pocari Sweat is a popular Japanese electrolyte drink designed to restore hydration and replace lost minerals and vitamins.
  • SPF, keep this on you to apply throughout the day.

Summer in Japan: August.

In Japan, August is typically the hottest month of the year; the golden triangle brings intense heat, which many people deem as unbearable. Tokyo, Osaka, and Fukuoka can see temperatures at 32 degrees Celsius, but many locals note the recorded temperatures feel a lot higher than the forecast. Kyoto remained the hottest city in Japan at the time due to its geographical situation. Thanks to Hokkaido’s natural breeze, the temperatures do rise here in August, but the evenings tend to be cooler than the majority of Japan.

August also marks the start of typhoon season. During August and September, Japan typically experiences around 2–3 typhoons per month. While they are not a daily occurrence, they can still cause disruption, particularly to flights and travel plans.

 

Summer in Japan Tip: Always have a back-up rainy day plan in august due to it being Typhoon Season.

What to wear in August:

  • Ultra-light clothing
  • Moisture-wicking fabrics
  • Sandals or breathable trainers
  • SPF

Again, August is another month where you will benefit from a “Cooling kit” and having those items at hand.

Cities come alive with vibrant celebrations, featuring street food stalls, traditional dances, and spectacular fireworks that honour Japan’s history, culture, and seasonal holidays.
 
At the same time, thousands of people flock to Japan’s stunning beaches, offering a refreshing contrast to busy cities like Tokyo. From white sandy shores to crystal-clear blue waters, Japan is home to some truly beautiful coastal destinations.
 
From Kyoto’s traditional festivals to Okinawa’s beautiful beaches, here are four things you can do—and everything in between.

1. Climb MtFuji

July to September is widely considered the best time to take on the challenge of climbing Mount Fuji, Japan’s highest peak. During this period, thousands of tourists make the ascent, with July being especially popular thanks to warmer temperatures and more accessible conditions.

 

With milder weather at higher altitudes, many hikers turn the experience into a two-day adventure, often staying overnight in mountain huts or camping, as the evenings remain relatively warm.

2. Attend a Matsuri festival

Kyoto Gion Matsuri

Don’t miss out to the chance to immerse yourself in rich Japanese Culture and attend a Japanese Summer Festival.

Kyoto Gion Matsuri – is a popular choice for tourists and locals. Held throughout July, expect potable shrines, traditional dances, and street food! Keep an eye out on their website for specific days where you can attend traditional Japanese Parades.

While the Golden Triangle hosts some of the most famous Natsumatsuri, summer festivals can be found all across Japan. They’re a great way to tick off multiple experiences at once, from food and culture to local traditions.

3. Spend a day on the beach

Being an island nation, Japan is home to many amazing beach locations. Okinawa may be the first place that springs to mind, with a year-round warm climate, this island attracts thousands yearly, and is a perfect place to enjoy a relaxing break. Shirahama, Wakayama, is another popular beach resort with white sands, and tourists have noted it to have “Mediterranean vibes”, or Kamakura’s Yuigahama Beach, just an hour from Tokyo and perfect for a quick seaside escape. Some may find it surprising to hear that you’re not short of beaches in Japan.

4. Experience Hanabi

Hanabi means “flower fire”: fireworks in Japan are considered a form of art, celebration, and used in remembrance ceremonies in Japanese culture. July and August are the main times of year Hanabi festivals are held, with the most famous one being the Sumidagawa Fireworks Festival in Tokyo. Again, known as the oldest Hanabi celebrations in Tokyo, easily accessible from the various parks scattered around the city. Alongside this Hanabi festival, there are many (some running from April to October) up and down the country. See below for the Hanabi Festivals of 2026.

Sumida River Fireworks Festival

One of Tokyo’s oldest and most iconic fireworks festivals, the Sumida River Fireworks takes place on the last Saturday of July. Set against the backdrop of Tokyo’s skyline, it offers multiple viewing spots to enjoy this world-famous Hanabi display.

Kyoto Art Fireworks

Held at Kyoto Racecourse—often considered Japan’s most beautiful racecourse—this fireworks show is a great choice for those who prefer a shorter display (around 60 minutes) and the option to reserve seating. It takes place on June 26th.

(Osaka) Senshu Yumehanabi at Sakai Daigyo Night Market

This unique take on a Hanabi evening takes place on July 25th, in collaboration with the Sakai Daigyo Night Market. Enjoy a blend of street food and fireworks all in one vibrant setting. Held at the historic Sakai Old Port, the display offers a memorable experience against the backdrop of the harbour.

Summer in Japan: What to eat?

Some tourists may debate going to Japan in the summer as they want to eat endless amounts of hot ramen, noodles and katsu curry! You can still do this in those warmer months, but we recommend you follow the locals and indulge in Kakigori instead. Kakigori (shaved ice) is a Japanese summertime delicacy. Shaved ice with syrup and loaded toppings can be found anywhere in the summer months. But if your heart is really set on noodles, you can enjoy some cold Somen noodles, or another cultural favourite, unagi (grilled eel).

 

Convenience stores even stock up on cold snacks, fruity desserts, and limited-edition summer treats. It’s less about heavy meals and more about light, cooling foods that help you actually cope with the heat—because in a Japanese summer, finding something cold isn’t just nice, it’s essential.

Is it worth visiting Japan in summer?

One of the most asked questions is whether Japan is worth visiting in the Summer. Is it bearable? Is it too hot? Can you still explore Japan in the heat?
 
Our team at Mobal, based in Tokyo are a mix of Native Japanese residents and expats. Of course, the residents love summer in Japan; they aren’t sightseeing and are prepared. However, our Irish expat in Tokyo Dec notes:
“Hokkaido is the obvious summer winner thanks to its cooler temperatures, but across the rest of Japan, the heat and humidity can feel pretty intense. That said, there’s definitely a silver lining—summer brings a whole culture of beer gardens, ice-cold drinks (sometimes even served in frozen glasses), late-night stargazing, and lively outdoor vibes. It might be a stretch for some, but if you lean into it, there’s still plenty to enjoy.”
 
Summer in Japan Tip: Experienced travellers often suggest avoiding summer for your first visit to Japan, but recommend returning in July or August to fully experience the country’s vibrant summer festivals once you’re more familiar with it.
 
In August 2025 alone, Japan welcomed 3,428,000 visitors, showing that the country continues to attract large crowds even during the peak summer heat.
Overall, with the right preparation and planning, visiting Japan in summer can be just as enjoyable as visiting in April. Just be sure to do your research and plan accordingly.
