Japan has experienced extreme heat for four consecutive days, an incident equalling the country's past record of continuous high temperatures. The sweltering heatwave has prompted public health warnings by the government and heated discussions about climate change among various sectors. The record-breaking temperatures, which peak during the mid-day, have caused concerns among locals and tourists alike.

In Japan, public safety and health are paramount. This heatwave has made headlines due to the risk it poses to people, especially the elderly, young, and those with underlying health conditions. Additionally, it has brought climate change back into the spotlight, with citizens and policymakers expressing alarm at the extreme temperatures and tying them to global warming.

In the US or EU, extreme temperatures also cause public concern about public health and climate change. Heatwaves often trigger public safety alerts and actions, such as the opening of cooling shelters and advisories to stay hydrated. Discussions surrounding climate change are also prevalent in these regions, albeit with varying intensities, as with Japan.
