Planning a trip to Japan during the summer months? Whether you’re visiting Tokyo, Kyoto, Osaka, or exploring the countryside, knowing what to wear can make a huge difference to your comfort.
Many first-time visitors underestimate just how hot and humid Japanese summers can be. While summer brings exciting festivals, fireworks, beaches, and seasonal food, it also means high temperatures, strong sunshine, and occasional heavy rain.
This guide covers what to wear in Japan during June, July, and August, plus practical packing tips to help you stay comfortable throughout your trip.
Understanding Summer Weather in Japan
Before deciding what to pack, it’s important to understand what summer in Japan is actually like.
June
- Rainy season begins in many regions
- Temperatures: 20–28°C (68–82°F)
- Humid with occasional showers
July
- Rainy season gradually ends
- Temperatures: 25–35°C (77–95°F)
- Hot and increasingly humid
August
- Hottest month of the year
- Temperatures often exceed 35°C (95°F)
- Strong sunshine and high humidity
Cities such as Tokyo, Kyoto, and Osaka can feel significantly hotter due to the urban heat effect.
The Most Important Rule: Dress Light
If there’s one piece of advice for summer travel in Japan, it’s this:
Wear lightweight, breathable clothing.
The combination of heat and humidity can make even moderate temperatures feel much warmer than expected.
Recommended Fabrics:
- Cotton
- Linen
- Moisture-wicking sports fabrics
- Lightweight blends
Avoid:
- Heavy denim
- Thick sweaters
- Tight synthetic materials
Comfort matters much more than fashion when walking several kilometers a day in summer weather.
What to Wear During the Day
For most sightseeing activities, simple and breathable clothing works best.
For Women:
- Lightweight dresses
- T-shirts
- Loose blouses
- Linen pants
- Comfortable skirts
For Men:
- Short-sleeve shirts
- Polo shirts
- Lightweight trousers
- Breathable shorts where appropriate
Many travelers find themselves changing clothes more frequently than expected due to the humidity.
Can You Wear Shorts in Japan?
Yes.
Contrary to some outdated travel advice, shorts are completely normal in Japan during summer.
You’ll regularly see locals wearing:
- Shorts
- T-shirts
- Sandals
- Casual summer clothing
However:
When visiting temples, shrines, or upscale restaurants, slightly more modest clothing may feel more appropriate.
There’s no strict rule, but dressing respectfully is always appreciated.
Comfortable Shoes Are Essential
Summer travel in Japan often involves a surprising amount of walking.
A typical sightseeing day can easily exceed:
- 10,000 steps
- 15,000 steps
- Sometimes even 20,000 steps
Best Choices:
- Comfortable sneakers
- Walking shoes
- Breathable sports shoes
Less Ideal:
- Brand-new shoes
- Heavy boots
- Shoes with poor ventilation
Your feet will thank you later.
Preparing for Japan’s Rainy Season
If you’re visiting in June or early July, rain should be part of your planning.
Bring:
- Compact umbrella
- Lightweight rain jacket
- Waterproof bag cover
Convenience stores sell umbrellas almost everywhere, but having your own can be helpful.
Sun Protection Is More Important Than Many Visitors Expect
Summer sunlight in Japan can be intense.
Many locals take sun protection seriously.
Useful Items:
- Hat or cap
- Sunglasses
- Sunscreen
- UV-protection umbrella
- Lightweight long sleeves
You will often see people carrying parasols even on sunny days.
Don’t Forget a Light Layer
This may sound strange during summer, but many indoor spaces in Japan use strong air conditioning.
Examples include:
- Shopping malls
- Trains
- Shinkansen
- Department stores
- Offices
- Theaters
A lightweight cardigan or thin jacket can be surprisingly useful.
