Japan's urban areas continue to be gripped by an extreme heatwave with people being urged to exercise caution. Major cities are bearing the brunt, with temperatures soaring well above the average summer levels. Doctors and authorities warn the public to stay hydrated, minimize outdoor activities during peak heat hours and watch out for signs of heat-related ailments. This follows an increasing trend of severe heatwaves in Japan in recent years, believed to be a consequence of climate change.

Heatwaves in Japan have become a serious societal issue with the recent increase in their intensity and frequency. With the elderly population being particularly vulnerable, it becomes a matter of public health concern. The government deploys measures like opening air-conditioned public buildings as heat-relief spots and circulating heat safety advisories, while citizens use traditional methods like consuming chilled barley tea and using "uchiwa" or handheld fans to keep cool.

While heatwaves are also a concern in regions like the US or EU, central air conditioning is much more widespread there, making it easier for people to escape the extreme temperatures. In Japan, heat relief measures can often be more makeshift due to the less extensive prevalence of central air conditioning in homes.
