Ten Ways Japan is Cooling Down This Summer

Summer in Japan can be intensely hot and humid. The Japan Meteorological Agency predicts above-average temperatures nationwide from July to September. Last summer reached record temperatures, and 2024 could be even hotter.

In Japan, much creative thought goes into this problem. Here are ten traditional and modern Japanese techniques to beat the heat. Some methods physically cool you down, while others provide relief through the sensation of cooling.

1. Folding Fans

Folding fans, or sensu, easily fit into bags or pockets. They provide a stylish way to stay cool with various patterns and sizes available. Traditionally associated with Japanese attire, they are now a common summer accessory for casual wear. It's especially refreshing to use them on crowded platforms and air-conditioned trains.

2. Wind Chimes

Japanese wind chimes (furin) produce a soothing sound with the slightest breeze. Though they don't lower the temperature, their delicate melodies can create a refreshing sensation by signaling the presence of wind. Furin are typically bell-shaped and made from glass or metal. They are often hung under house eaves, near windows, or on balconies during the summer months. They also make excellent souvenirs if carefully packed.

3. Iced Barley Tea

Known as mugicha, iced barley tea is a popular summer drink in Japan. It's hydrating, caffeine-free, sugar-free, and rich in minerals. While bottled versions are available, purchasing tea bags is recommended. You can make a liter of tea with each. This allows you to easily prepare your own barley tea at a much lower cost.

4. Shaved Ice

Most visitors to Japan have tried shaved ice, known as kakigori, and this long-established summer treat is making a comeback this year. Served with a variety of flavored syrups, it offers a delightful way to cool down from the inside out. 

The flavor options continue to expand, with popular choices such as green tea, strawberry, melon, and innovative options like coffee and mango. The texture of the ice can vary by establishment, ranging from a fluffy, snow-like consistency to crunchier textures.

5. Neck Cooling Rings

These rings are infused with a cooling gel that provides a pleasant chill when worn around the neck. To activate a typical cooling ring, chill in the freezer for 10 minutes or immerse in cold water for 15 minutes until frozen. They usually remain cool for up to 60 minutes in outdoor temperatures ranging from 25 to 36°C and can be reused repeatedly. Refer to package instructions for details.

6. Menthol Spray and Peppermint Oil

Menthol sprays and peppermint oil create an instant cooling effect. Pairing them with a handheld fan can significantly enhance comfort during the summer heat. Some are designed for direct skin application, while others are for clothing. Make sure to avoid contact with your eyes!

7. Cooling Wipes

Body wipes (often called "body sheets" in Japan) come in various scents and cooling intensities. These moist sheets provide relief by effectively removing sweat and dirt. They also offer disinfecting and deodorizing benefits. Found in convenience stores, they are handy to keep in your bag on long days. Products from Gatsby and Biore are popular.

For an economical alternative, a damp towel around your neck or tucked into the back of your hat can also provide relief. However, body wipes are often preferred when the humidity is high.

8. Hiyashi Chuka

Hiyashi Chuka is a dish of chilled noodles served with toppings and a flavorful sesame or vinegar-based sauce. It's perfect for those who crave ramen but want to avoid its heat and steam. Typically garnished with cucumbers and tomatoes, this dish offers a refreshing flavor profile. You can enjoy it at restaurants or quickly prepare it at home with supermarket noodles that come with the sauce.

9. Electric Fans, Circulators, and Personal Fans

Most Japanese households use either an electric fan or a circulator at home. While both serve similar functions, fans create a direct breeze for cooling, whereas circulators enhance room-wide air circulation. When paired with an air conditioner, circulators boost efficiency by redistributing cold air. This could potentially lower the energy bill by allowing for higher thermostat settings.

Portable battery-powered fans have become a common sight in Japan. Handheld options are compact and easy to carry, while neck fans have become much more lightweight and less clunky than when they first appeared on the market. Stores like Don Quijote offer a good selection.

10. Cooling Fabrics 

Clothing and accessories made from cooling fabrics are designed to regulate body temperature during summer. Major Japanese brands like Muji, Uniqlo, and Nitori regularly introduce bedding, pajamas, and undershirts made from these materials. Engineered to wick moisture away from the skin, they offer a cooling effect upon contact. Some reviews also note improved sleep quality.
