Japan encountered an unseasonal, scorching heatwave on the 6th day from west to east, an anomaly typically not seen during this time of year. The sudden rise in temperature resulted in a change in daily activities and took a toll on public health. Local authorities were forced to issue advisories to stay hydrated and limit outdoor activities as a preventive measure against heatstroke amid this unusual hot weather.

As in any country, climate anomalies, especially such abrupt shifts, concern the Japanese public greatly, mainly due to potential negative impacts on public health and everyday life. Japan has sophisticated infrastructure to deal with heatwaves, such as Cool Biz campaign and specialized heatstroke education programs, as an integral part of coping with the growing global challenge of climate change.

In the US and EU, incidents of unseasonal heatwaves occur as well, triggering similar reactions such public health advisories and alteration of daily life activities. Like Japan, they also employ climate action strategies to mitigate the effects of climate change at both the policy and ground level.
