Japan sells wearable human fridge cooling devices during heatwave

Japan is enduring an unprecedented summer heat wave, with temperatures in major cities regularly exceeding 35 °C (95 °F) and heat‑related health advisories issued by the government. Amid the sweltering conditions, BBC Tokyo correspondent Kurumi Mori stepped outside the newsroom to test a newly introduced personal‑cooling solution designed to help individuals cope with the extreme temperatures. The device, which integrates a compact cooling system into a wearable format, aims to lower body temperature without the need for stationary air‑conditioning units.

Mori’s trial highlighted both the practical benefits and the growing demand for portable heat‑relief technologies as Japan grapples with increasingly severe summer weather. Observers noted that such innovations could alleviate strain on public cooling infrastructure and provide immediate relief for workers and commuters. The experiment underscores a broader shift toward adaptive measures in response to climate‑driven heat events, suggesting that personal cooling tools may become a more common fixture in daily life across the country.
