Summer in Japan is undeniably magical. It is the season of vibrant matsuri (festivals), wearing breezy yukata, watching massive firework displays, and eating fluffy kakigori (shaved ice).
But let’s be completely honest: the summer heat and humidity in Japan are no joke. If you are traveling between June and September, preparation is the difference between a miserable, sweaty trip and the vacation of a lifetime.
As local guides at Milocal Japan, we spend all summer helping our guests navigate the elements. Here are the top 5 things you need to prepare before you board your flight.
1. Pack the Right Fabrics (Leave the Jeans at Home)
The humidity in Japan will make heavy fabrics feel like a sauna. Your packing list needs to focus on lightweight, breathable, and quick-drying materials.
-
What to bring: Linen shirts, moisture-wicking activewear, and loose, flowy clothing.
-
What to skip: Denim jeans, thick cotton t-shirts, and tight clothing.
-
Local Tip: Don’t overpack! You can always visit a Uniqlo when you arrive to stock up on their famous “AIRism” undershirts, which are designed specifically for the Japanese summer.
2. Prepare Your “Sun Defense” Arsenal
The Japanese sun is intense, and locals take UV protection very seriously. While you can buy many of these items here, having a few basics ready for day one is crucial.
-
Sunscreen: Bring your favorite facial sunscreen, but plan to buy Japanese body sunscreen (like Biore UV Aqua Rich) at the pharmacy—it is lightweight and non-greasy.
-
UV Parasol: You will see almost every local carrying a UV-blocking umbrella. It creates instant shade wherever you walk. You can easily buy a stylish, foldable one at any department store or loft when you arrive.
3. Plan for “Konbini” Cooling Hacks
You don’t need to stuff your suitcase with cooling gadgets from Amazon. Japanese convenience stores (konbini) are basically survival centers in the summer. Plan to buy these cheap, highly effective items as soon as you land:
-
Cooling Body Wipes: Brands like Gatsby or See Breeze sell icy menthol wipes that instantly drop your skin temperature and make you feel freshly showered.
-
Neck Coolers: Look for the gel “ice rings” that freeze below 28°C (82°F) to wear around your neck.
-
Hydration Drinks: Memorize the names Pocari Sweat and Aquarius. These Japanese sports drinks are life-savers for replenishing electrolytes lost through sweating.
4. Rethink Your Daily Itinerary Timing
The biggest mistake tourists make is trying to visit massive, unshaded temple complexes (like Kyoto’s Fushimi Inari or Tokyo’s Meiji Shrine) at 1:00 PM.
-
The Strategy: Plan your outdoor sightseeing for the early morning or late afternoon. Use the hottest midday hours (11:00 AM to 3:00 PM) to explore air-conditioned museums, underground shopping malls, or to sit down for a long, relaxing sushi lunch.
5. Book Private Transportation to Escape the “Transit Sweat”
Here is a local secret: the heat isn’t what exhausts tourists—it is the transit. Walking 15 minutes to a train station, standing on a sweltering outdoor platform, and dragging heavy luggage through crowded subways in 35°C (95°F) weather will drain your energy before your day even begins.
-
