Japan issues strict heatstroke warnings as extreme heat grips Tokai and Kyoto regions
NHK reports a nationwide surge in heatstroke-related emergency transports as forecasts predict continued extreme conditions across central Japan.

Japanese meteorological authorities have classified parts of the Tokai region as experiencing "extreme heat days" following maximum temperatures surpassing 40 degrees Celsius on 22 July 2026. The prefectures of Mie, Shizuoka, and Gifu recorded these record-breaking highs, prompting immediate public health alerts.
Forecasts issued by NHK indicate that the extreme heat will persist into 23 July, affecting the broader Tokai region, which comprises Aichi, Gifu, Mie, and Shizuoka prefectures. Additionally, Kyoto City and Kofu City are specifically projected to experience extreme heat conditions on the same day.
The classification of "extreme heat day" (kōkotsubi) is a formal designation used by Japanese weather agencies to denote days where maximum temperatures exceed 40 degrees Celsius. This threshold triggers heightened vigilance protocols across local governments and emergency services.
In response to the severe weather, authorities have issued strict warnings regarding heatstroke prevention. NHK highlighted that emergency transports for heatstroke have surged nationwide, indicating a significant strain on medical resources and public safety infrastructure.
Public health campaigns are currently emphasising the use of air conditioning and adequate hydration, with specific guidance directed at vulnerable demographics, including the elderly and children. The ongoing heatwave underscores the increasing frequency of extreme weather events requiring coordinated governmental response.
