1. Overview of Japan Weather in July 2026
Heat and humidity after the rainy season: By early to mid-July, the rainy season (tsuyu) comes to an end across Japan, ushering in the peak of summer with steadily rising heat and humidity. Major cities such as Tokyo, Osaka, and Kyoto experience daytime highs of above 30°C, and the intense humidity makes it feel sweltering (nights also remain quite warm).
Expect strong sunshine and be vigilant with sun protection and heat precautions. Also, be prepared for sudden afternoon downpours or thunderstorms, nicknamed 'guerrilla rainstorms' for their surprising intensity, by carrying an umbrella or light rain jacket.
North vs. South – Finding Cooler Areas: In contrast, northern regions such as Hokkaido enjoy much cooler and more pleasant weather in July, with average temperatures of around 15–25°C. If you're sensitive to heat, consider including Hokkaido or high-altitude mountain areas in your itinerary. These are popular summer retreats for locals, offering a refreshing escape from the heat.
Average July Temperatures in Major Japanese Cities
| City | Daytime Avg. Temp | Nighttime Avg. Temp | Weather Notes |
| Tokyo | 28–31°C (82–88°F) | 23–25°C (73–77°F) | Hot, humid, sunny after rainy season; strong UV, occasional sudden showers |
| Osaka | 29–33°C (84–91°F) | 24–26°C (75–79°F) | Hotter and stickier than Tokyo; lively evenings, but the humidity is heavy |
| Sapporo (Hokkaido) | 19–25°C (66–77°F) | 15–18°C (59–64°F) | Cool, refreshing; lavender season; light jacket recommended for evenings |
Tokyo Weather in July
July in Tokyo is hot and humid, with average daytime temperatures ranging from 28°C to 31°C (82°F to 88°F) and nighttime temperatures of around 23°C to 25°C (73°F to 77°F).
Once the rainy season ends, the sunshine feels strong, so remember to pack a hat, sunscreen, and sunglasses.
It is a good idea to plan outdoor sightseeing for the early morning or late afternoon and escape the midday heat by visiting museums, shopping malls, or cafés with powerful air conditioning.
Osaka Weather in July
Osaka is often even hotter than Tokyo, with average daytime temperatures ranging from 29°C to 33°C (84°F to 91°F) and nighttime temperatures from 24°C to 26°C (75°F to 79°F).
The lively food stalls and neon-lit streets make for an exciting summer evening, but the humidity can be overwhelming.
Follow the locals' example and carry a small towel to wipe away sweat. Pop into convenience stores for a quick blast of cool air and a refreshing drink.
Sapporo Weather in July
By contrast, Sapporo experiences much milder weather in July, with daytime highs of 19–25°C (66–77°F) and cool, comfortable nights at 15–18°C (59–64°F).
This makes Hokkaido one of the best places to escape the summer heat in Japan. The lavender fields in Furano and the mountain hiking trails are at their best, but remember to pack a light jacket for the cool evening breezes.
Travel Tip:
Intense UV rays are common across Japan in July. Be sure to stay hydrated and reapply sunscreen frequently.
Take advantage of Japan's endless convenience stores – their seasonal frozen treats, such as the famous watermelon popsicle (Suika Bar), are a fun and tasty way to cool down.

2. How to Enjoy Japan in July: Experiences for Everyone
For Families – Indoor Theme Parks as Cool & Fun Escapes
Start your day early with a visit to the outdoor spots in Asakusa Temple or Meiji Jingu Shrine. Or some cooler outdoor activities, such as a trip to the beach or a day at a water park.
To escape the midday heat, head indoors to an aquarium, a science museum, an indoor theme park, or a shopping mall. Tokyo Joypolis, located in Odaiba, for example, offers arcade games and VR rides in a fully air-conditioned environment. Sanrio Puroland in Tama delights kids with Hello Kitty and friends in a whimsical indoor world. Meanwhile, Legoland Discovery Centre Osaka is perfect for younger children who want to burn off energy without facing the summer sun.
If you're planning a summer getaway, Okinawa is the perfect destination in July. The rainy season ends in late June, and by mid-July, the clear skies and warm waters are ideal for snorkelling, relaxing on the beach and visiting the famous Churaumi Aquarium, which is popular with both children and adults.

For Couples – Romantic Nights under Fireworks & Artistic Escapes
Nothing beats the romance of a Japanese summer festival. Slip into a light yukata, stroll hand in hand through lantern-lit stalls, share a bowl of shaved ice, and watch the fireworks illuminate the night sky.
While major events such as Kyoto's Gion Matsuri and Tokyo's Sumida River Fireworks are unforgettable, even a small-town festival can feel magical.
If you're looking for something more intimate, try the Tanabata Festival (Star Festival) in early July, where you can write wishes on colourful tanzaku papers together and hang them on bamboo to create a charming memory.
Looking for a break from the heat? Spend a few hours indoors exploring a seasonal art exhibition at museums such as the Mori Art Museum in Tokyo or the National Museum of Art in Osaka. Another romantic idea is to head up an observation tower, such as the Tokyo Skytree or the Umeda Sky Building in Osaka, where you can enjoy panoramic city views in superb, air-conditioned comfort.

3. Festivals and Celebrations in Japan, July
July in Japan is festival season, when the excitement of tradition, music, and fireworks offsets the summer heat. Locals slip into light yukata robes, grab a fan or small towel, and head out with friends or family, eager to enjoy festive food and music together under the magic of a summer evening.
You may want to know the July festival events below:
Kyoto's Gion Matsuri: The most famous of them all lasts the entire month of July and has been celebrated for over 1,100 years. The highlight is the grand float parade on 17 July, when towering, ornate floats roll through Kyoto's streets. In the days leading up to the parades, the lively Yoiyama nights (July 14–16) offer the chance to sample street food and music, as well as to see the floats up close. You may notice locals writing their wishes on small charms, sampling festival snacks such as takoyaki and yakitori, and pausing to admire the intricate details of the floats – simple rituals that make the experience feel special.
Fireworks festivals: July also marks the start of hanabi taikai (fireworks displays). Tokyo's Sumida River Fireworks Festival and Osaka's Tenjin Matsuri fireworks displays draw huge crowds of people who gather in their yukata along the riverside to watch the spectacular shows. Families spread out their picnic blankets, couples share shaved ice, and friends cheer at each burst of colour – scenes that encourage you to join in the fun of the festivals.
Vibrant, colourful and unforgettable — these are the words that best describe Japan's July festivals.
Let these dazzling celebrations illuminate your summer journey! Get in touch today to create a personalised itinerary showcasing Japan's July festivals and fireworks displays. Avoid the hassle of research and booking — enjoy everything you've ever dreamed of.

4. Cooling Off Like a Local in July
Staying cool is a key consideration when traveling in Japan during the summer months. We're now revealing the local Japanese secrets for beating the heat.
Carry the essentials: In Japan, a mini electric fan and a small towel are everyday summer essentials – perfect for wiping away sweat or catching a breeze in the shade.
Convenience store pit stops: Come inside to cool down and enjoy a chilled drink or a popsicle. Be sure not to miss the famous watermelon popsicle (Suika Bar). You can also pick up a bottle of Pocari Sweat, Japan's most popular sports drink. It's perfect for rehydrating and replenishing electrolytes on a hot summer's day. Both options are refreshing, fun, and quintessentially Japanese!
Cool treats: Try seasonal favourites such as shaved ice (kakigōri), ice-cold watermelon, or chilled somen noodles. They're light, tasty, and perfect for hot weather.
Stay hydrated: Chilled barley tea (mugicha) and sports drinks are popular choices. Replenishing both water and salt is an essential way for Japanese people to avoid heatstroke.

5. Smart Packing List for a July Trip to Japan
When it comes to summer in Japan, packing smartly makes all the difference. July brings plenty of sunshine and high UV levels, as well as sudden bursts of rain, so a little preparation will ensure you enjoy a comfortable and carefree journey.
Light, breathable clothing: Pack light, breathable clothing such as airy shirts, shorts, skirts, or dresses made from cotton or quick-dry fabrics. A lightweight long-sleeved shirt or thin jacket is useful too, as it's perfect for strong sunshine outdoors or overly chilly air conditioning indoors.
Sun protection is non-negotiable: Bring a wide-brimmed hat, sunglasses, and high-factor sunscreen. If you're spending time outdoors at festivals or sightseeing, reapply often to avoid sunburn.
Rain and bugs: Early July can still bring pop-up showers, so be sure to pack a travel umbrella or compact poncho in your bag. If you're exploring gardens or rural areas, insect repellent or mosquito patches will prevent itchy bites.
Stay hydrated: Always carry a reusable water bottle that you can refill at vending machines or fountains. Many locals also drink chilled barley tea or sports drinks, such as Pocari Sweat, to cool down and replenish electrolytes.
Local secret: carry a towel! A small hand towel is almost a summer essential in Japan. Use it to dab away sweat or wet it slightly and place it on your neck for instant relief.
Daypack convenience: A comfortable backpack keeps everything organised and leaves your hands free. It's also perfect for holding the souvenirs you'll pick up at festivals or markets.
Don't worry if you forget something – Japan's convenience stores and drugstores are everywhere, stocked with essentials like sunscreen, cooling wipes, insect repellent, and even spare umbrellas. I totally get it. Sometimes, the easiest way to stay stress-free is to travel light and pick up what you need along the way. ;)

6. How Busy Is Japan in July? Travel and Hotel Tips
Peak travel season
When: Late July to mid-August.
Why: Schools close for the summer holidays, families travel, and the Obon Festival sees many domestic travellers on the move.
Impact: Popular attractions, trains, and hotels can become crowded, especially in major cities, beach resorts, and mountain retreats.
The smart move
Try to travel in early July if you can.
The rainy season has just ended.
Summer festivals are just beginning.
The crowds are smaller before the school holidays begin, which usually start at the end of July.
This period is lively but not overwhelming, and is often the best time to visit in July.
If you're travelling during peak season
