Introduction
Japan’s summer is famously hot, humid, and intense!
From late June to early September, temperatures often soar above 30°C (86°F), with humidity levels that can make it feel even hotter.
But don’t worry—locals have developed plenty of smart ways to stay cool and comfortable.
Here’s your essential guide to surviving (and even enjoying!) the hot and humid Japanese summer.
1. Dress Light and Smart
Choosing the right clothing can make a huge difference.
Opt for light, breathable fabrics like cotton and linen.
Loose-fitting clothes and light colors reflect heat better than dark, tight clothing.
Tip: Many Japanese brands sell “cool touch” clothing designed specifically for summer!
2. Always Carry a Folding Fan or Portable Fan
You’ll notice many people in Japan carrying small handheld fans (uchiwa or sensu) or portable electric fans.
They’re lifesavers when standing in crowded trains or waiting outdoors.
3. Stay Hydrated with Pocari Sweat and Aquarius
Japan’s humid summer causes you to sweat more, so staying hydrated is crucial.
Local sports drinks like Pocari Sweat and Aquarius help replenish electrolytes lost through sweating.
Bonus: Convenience stores are everywhere, making it easy to grab cold drinks anytime!
4. Use Cooling Products
Japan offers a wide range of summer survival goods:
- Cooling body wipes
- Cooling sprays for clothes and skin
- Cooling gel sheets (hiyashi sheeto) for your forehead
These inexpensive items are available at convenience stores, drugstores, and 100-yen shops.
5. Take Advantage of Air-Conditioned Spaces
Shopping malls, museums, and even some temples and shrines offer cool, air-conditioned spaces.
If the heat gets overwhelming, step inside and enjoy a refreshing break!
6. Eat Refreshing Foods
Cooling foods like sōmen (cold noodles), kakigōri (shaved ice), and suika (watermelon) are summer staples.
They not only help cool your body but also give you a real taste of Japanese summer culture.
7. Watch Out for Heatstroke
Symptoms of heatstroke include dizziness, nausea, and excessive sweating.
If you feel unwell, find a cool place to rest immediately, drink water, and don’t hesitate to seek medical help if necessary.
Important: In Japan, summer heatstroke cases are taken very seriously, and many public announcements offer tips on prevention.
Conclusion
While the Japanese summer can be challenging, it’s also a vibrant and exciting time filled with festivals, fireworks, and delicious foods.
With a few smart strategies and the right gear, you’ll not only survive the heat—you’ll thrive in it!
