Japan issues nationwide heatstroke alerts amid soaring summer temperatures

The Ministry of the Environment has issued heatstroke alerts across Japan as maximum temperatures reach 36‑37 °C in regions such as Fukushima, Tochigi, Kyushu and Kyoto. Local governments advise residents to stay indoors, hydrate frequently, wear protective clothing and use air‑conditioned spaces. Many municipalities have opened cooling shelters and "suzumizukuri" (cooling spots) for vulnerable populations, while the Kyoto prefecture recorded its first 36 °C day of the season.

Employers are also tightening safety measures. In Fukui, a consumer‑cooperative uses delivery staff to check on isolated seniors and monitors staff health with digital tools. Construction sites in Toyama employ body‑temperature watches, cooling vests, on‑site water stations and adjusted work hours to protect workers. The new labor‑safety law obliges all businesses to implement heatstroke prevention plans.

Agricultural workers face the highest risk. The Ministry of Agriculture reported a record 59 heat‑related deaths in 2024, with rates three times the national average. Officials warn that rising fatalities could accelerate farm abandonment and threaten food supplies. Nationwide training, early‑warning devices and subsidised cooling equipment are being promoted to curb the trend.

Meteorological forecasts also predict continued extreme heat in central and eastern Japan, with the approaching former Typhoon 9 expected to bring additional high‑temperature days and heavy rain in the north. Authorities stress the importance of staying hydrated, avoiding strenuous outdoor activity and seeking immediate medical help for heatstroke symptoms.
