Tokyo Summer Heat - My 14 Years of Tested Tips
Tokyo summers can be surprisingly difficult to prepare for.
Before moving here, I expected the heat. What I didn't expect was the humidity. Walking a few minutes outside can leave you completely soaked, and carrying groceries, camera gear, or even a backpack only makes it worse.
After more than 14 summers in Tokyo, I've gradually found the clothing and gear that genuinely make everyday life more comfortable. None of this is sponsored, and there are no affiliate links—these are simply the products I bought myself after years of trial and error.
Watch the Full Episode
Staying Comfortable Starts with Your Clothing
The biggest difference wasn't buying expensive gadgets. It was replacing ordinary clothing with fabrics designed for hot, humid weather.
Quick-drying underwear, lightweight shorts, moisture-wicking shirts, and five-toe socks all sound like small upgrades, but together they dramatically reduce how uncomfortable long walks become during Tokyo's summer.
Instead of staying damp for hours, everything dries much faster, making everyday errands far more manageable.
Fan Jackets Actually Work
Before moving to Japan, I probably would have laughed at someone wearing a jacket with built-in fans.
Now I own one myself.
Fan jackets have become common during Japanese summers, especially among construction workers and anyone spending time outdoors. The fans continuously circulate air through the shirt, making your body's natural cooling much more effective.
When I first tried one, I immediately understood why they're so popular.
Cooling Down Without Making Noise
Not every situation is suitable for a fan jacket, though.
On trains, in cafés, or during meetings, I've found cooling neck rings to be one of the most useful summer accessories. They stay cool surprisingly long, don't drip water everywhere, and provide just enough relief while commuting or sitting indoors.
They're one of those products I probably wouldn't have bought before living here, but now I use them every summer.
Preparing for Tokyo's Weather
Summer in Tokyo isn't just hot—it can change very quickly.
Bright sunshine can turn into a heavy downpour with very little warning, so I've learned to carry weather-resistant bags whenever I have camera equipment or electronics with me. A good cap and polarized sunglasses also make a much bigger difference than I expected, especially when sunlight reflects off glass buildings and pavement throughout the city.
After enough summers, preparing for both heat and sudden rain simply becomes part of leaving the house.
The Setup I Actually Use
- BROS by Wacoal boxer briefs
- Uniqlo quick-drying shorts
- Helikon-Tex TopCool Lite shirt
- Uniqlo five-toe socks
- Burtle fan jacket when spending long periods outdoors
- Cooling neck ring for trains and indoor spaces
- Polarized sunglasses and a comfortable cap
- Weather-resistant bag whenever I'm carrying electronics
None of these completely eliminate Tokyo's summer heat, but together they make it much easier to function without feeling exhausted all day.
Living with Tokyo Summers
No piece of equipment is going to make August feel cool.
Eventually, you learn to plan your day around the weather—walking through shaded streets, taking advantage of convenience stores to cool down, carrying plenty of water, and accepting that summer simply moves at a slower pace.
The heat never really gets easier, but you do get better at living with it.
If you've found something that makes Japanese summers more comfortable, I'd love to hear about it. I'm always interested in discovering products or habits that make life here just a little easier.
