Japan's Meteorological Agency has predicted a probable 1% increase in the locations experiencing intense heat in June compared to last year. This forecast has triggered concerns over rising temperatures amid summer and its repercussions on lives and various sectors, including agriculture, health, and energy consumption. The development closely aligns with the global trends of worsening heatwaves attributed to climate change.

In Japan, intensifying heat is becoming a major concern, especially in summer months. Excessive heat not only disrupts daily life but also impacts productivity at work, well-being, and public health, seeing the history of heat-related illnesses and even deaths in the country. It also significantly affects agriculture and energy consumption, which is particularly important considering Japan's sustainability and energy security goals.

In the US or EU, similar heatwave predictions also mobilise governments towards increasing infrastructural resilience against heat, enhancing public health support, and updating mitigation and adaptation strategies. These regions too share concerns over rising temperatures and the health hazards they pose, especially to vulnerable populations such as the elderly and those with chronic conditions.
