Japan is set to face a potential relentless surge of heatwave over the weekend, affecting both western and eastern regions of the country. Local meteorological sources speculate a spate of "mōshobi", or extremely hot days, which generally are days where temperatures exceed 35°C. The citizens, particularly the elderly and those with health conditions, are advised to take necessary precautions to avoid heat-related illnesses. Additionally, the increasing frequency of these heatwaves is seen as another local impact of global climate change.

Compared to the past, Japan experiences these heatwaves more frequently and severely - something that is particularly concerning for a nation with a large elderly population. Heat-related illnesses can be fatal, so people in Japan usually take these warnings very seriously, with many often staying indoors, avoiding the sun, and keeping themselves hydrated.

In comparison to US or EU, Japan's response to heatwaves is quite similar. All these regions issue warnings to their citizens to take necessary precautions. However, Japan has a higher risk due to its significant aging population who are more susceptible to heat-related illnesses. Recognizing the threat of climate change, these countries are also taking various measures to mitigate its effects, like advancement in renewable energy and emission reduction goals.
