Japan's proactive measures have reportedly decreased heatstroke-related deaths below 1000 in the early stages of summer. This achievement follows intensive public health campaigns aimed at increasing people's vigilance towards the deadly effects of severe summer heat, especially among vulnerable groups such as the elderly and children. The government's strengthening of medical services and climate-smart urban designs has also contributed to this success.

Heatstroke is a serious concern in Japan, particularly during the early stages of summer when the population is yet to fully acclimatize to the severe heat. The issue is closely related to Japan's aging society, as the elderly are more susceptible to heatstroke. There are also social values at stake, such as Japan's emphasis on community care and well-being. The government's strategy reflects these values, focusing not just on medical services but also on public awareness and community resilience.

The US and EU also handle heatstroke and other heat-related illnesses seriously, but the challenge varies depending on their geographical and demographic contexts. While the EU is implementing heat health warning systems and urban heat island prevention policies, in the US, efforts are more focused on individual states and regions with extreme heat conditions.
