Item 2: Portable Fan
Trains, temples, and theme parks can get stifling.
Hands-free neck fans or USB rechargeable handheld fans are everywhere in Japan — and they work!
Item 3: Sunscreen (Sweat-Proof!)
Japan’s UV index is high in summer, and the humidity makes reapplying sunscreen even trickier.
That’s why lightweight, non-sticky Japanese sunscreens like Anessa and Biore UV are traveler favorites

Item 4: Mosquito Repellent (and Itch Relief)
Japan’s summer is not just hot — it’s buggy, too.
Especially near parks, rivers, and shrines, mosquitoes can be surprisingly aggressive.
Bring your favorite repellent from home or pick up patches or sprays in Japan’s drugstores.
You’ll find a wide range of mosquito repellents in Japan:
Mosquito Repellent bracelets for kids
Oniyama-kun: a fake dragonfly that mimics a mosquito’s natural predator!
Got a bite?
Anti-itch creams and patches are also widely available. Stock up on Amazon Japan or stop by a local drugstore.

Item 5: Breathable, Quick-Dry Clothing
Humidity is part of daily life in Japan’s summer, so wearing breathable, moisture-wicking fabrics makes a huge difference.
Quick-dry shirts, lightweight shorts, and moisture-wicking socks are lifesavers when walking around cities in the heat.

Japan’s summer is hot — but don’t let the heat stop you from enjoying it all.
