A severe heatwave is forecasted for Japan's Kanto region on the 23rd, posing potential health risks to residents. The extremity of the predicted heat has led meteorologists to label the day as 'dangerously hot,' suggesting residents take necessary precautions to protect themselves from the potentially intense heat.

The public tends to respond to extreme weather warnings seriously in Japan, including heat waves. The population is generally well aware of the risks associated with extreme heat conditions, such as heatstroke and dehydration, and authorities will take measures to ensure public safety. It's common for older citizens and children specifically to take preventative steps to protect themselves.

Like Japan, the US and EU take heat warnings seriously. Health advisories are sent out, advising people to stay indoors, keep hydrated, and avoid physical exertion during peak heat times. However, the infrastructure and societal response may slightly vary due to cultural differences.
