Beating the Heat: Products to Help You Navigate Japan's Sweltering Summer
In Japan, where summer temperatures are on the rise each year [1], the most popular cooling goods for beating the heat include neck coolers, portable fans, and cooling towels or wipes.
Neck Coolers
Neck coolers are widely used due to their affordability and battery-free nature. They contain a special liquid that freezes at around 28°C and can be re-frozen simply by immersion in cold water or by staying in an air-conditioned room [1]. These coolers cool the neck and major blood vessels, effectively lowering body temperature, and are safe for all ages, including children and the elderly, when used at less chilly temperatures [1].
Portable Fans
Portable fans gained popularity around 2018 and have since evolved. Modern versions may include Peltier cooling plates, which can reduce temperatures by about 13°C on contact, enhancing cooling effects, especially on the neck when combined with airflow [1]. USB-rechargeable varieties are commonly used [2].
Cooling Towels and Wipes
Cooling towels and wipes are also popular, often featuring cooling mists and wipes from well-known Japanese brands like Sea Breeze. These products provide a simple way to cool down after being in the heat [2]. They are commonly used in Japan to remove sweat and provide evaporative cooling [3].
Other notable cooling goods mentioned include instant cooling packs like Lotte Hiyaron and specialized cooling blankets designed for Japan's climate [3][4]. Rechargeable portable coolers and compact devices such as the “Ice Kairo” also provide instant cooling relief by applying coolness to sweat-prone areas [5].
Thus, neck coolers, portable fans (including advanced cooling fans), and cooling towels/wipes remain the core popular items for summer heat relief in Japan. These cooling goods can be found at convenience stores and drugstores around town [3].
As companies continue to develop creative tools to help residents cope with the heat [6], it's clear that Japan is prepared to take on the summer months with cool, innovative solutions.
