Japan's heatwave spurs surge in portable cooling gadgets

Retailers in Japan are promoting a range of personal cooling products as summer temperatures climb.

3COINS highlights three affordable items: a temperature‑display 4‑way fan usable handheld, tabletop, on‑neck or as a phone stand; a silicone‑coated cooling stole that feels icy on the skin; and a neck‑wearable ice pack that chills without batteries. Prices range from ¥330 to ¥2,750.

STANLEY recommends three insulated bottles that keep drinks cold for five to six hours, featuring flip‑top lids, lightweight aluminium construction and easy cleaning. Models include the Transit Flip Mug (¥4,620), the Aero‑Light vacuum bottle (¥5,500) and a smaller 0.35 L version (¥4,620).

Gizmodo reports on the “Gorilla Cold Stick,” an aluminium ice‑pack that can be frozen to about 2 °C and stays cool for over three hours even in 35 °C ambient heat, offering a handheld cooling solution for commuters and office workers.

Lifehacker reviews the YAMAZEN “Cold‑air Fan” (FCR‑J402), an evaporative cooler that uses a 2.5 L water tank to produce a gentle chilled breeze while consuming about ¥1 per hour of electricity. It includes adjustable wind settings, a timer and a remote control, positioning it as a low‑cost alternative to air‑conditioning for families and children.
