1. Cooling Gel Mats
Cooling gel mats are a go-to summer item in many Japanese homes, especially for getting a better night’s sleep during hot, humid weather. They work without electricity—simply place one on your bed or chair for a cooling sensation. They're ideal for households trying to limit air conditioner use and are safe for children and pets. In Japan, they’re widely seen as an easy way to improve sleep quality in the summer and are continuously being updated each year. Their foldable design and portability also make them great for outdoor events or travel.
2. Handy Fans (Portable Fans)
Handy fans have become a common sight in Japan during the summer—used in trains, on the street, and at events. Particularly popular among Gen Z and millennials, these fans are often treated as both practical tools and fashion accessories. Compact and easy to carry, they’ve evolved with features like USB charging, quiet operation, and long battery life. Handy fans are especially useful in places where air conditioning isn’t available, such as outdoor events. With a wide variety of styles and colors, they’re also a popular choice for summer gifts and promotional items.
3. Personal Air Coolers
While not as powerful as a full air conditioner, personal air coolers offer a practical, budget-friendly way to stay cool. They’re especially well-suited for small spaces like studio apartments or individual rooms—ideal for Japan’s compact living environments. These devices work by using water or ice to create a cooling breeze, which also helps avoid the dryness often caused by traditional AC. Their natural cooling method appeals to users who prefer a more eco-conscious lifestyle, and their reasonable price point has made them increasingly popular among younger people and those living alone.
4. Wearable Neck Coolers
Wearable neck coolers are designed to lower overall body temperature by cooling the neck area directly. In Japan, they’ve rapidly gained traction as an effective way to prevent heatstroke and are now widely used by people working outdoors, such as in construction or event staffing. In recent years, models with sleeker designs and high-tech features, such as Peltier cooling elements, have been introduced. These updated versions combine functionality with style and are becoming a new summer staple. Their rechargeable and reusable nature also aligns with the growing interest in sustainability.
5. Cooling Towels and Scarves
Cooling towels and scarves offer a simple yet effective way to stay cool: just soak, wring, and snap to activate the chilling effect. They're especially effective in Japan’s hot and humid climate, and are often used during summer festivals, sporting events, or commutes. Because they’re washable and reusable, they’re an economical choice, and many families keep several on hand. Available in stylish patterns and character prints, they’re particularly popular with children and women.
