Japan faced soaring temperatures on July 21, as a powerful high-pressure system drove the mercury past 40°C in multiple regions, marking the ninth year in a row of such blistering heat. The phenomenon was underscored by the introduction of the term “kokushobi,” or “cruelly hot days,” this past April, used to describe these intensely sweltering conditions.
In Gifu Prefecture, the city of Tajimi recorded the nation’s highest temperature for the day, reaching a scorching 40.3°C. Nearby Gujo was not far behind, with temperatures hitting 40°C, while Toyota in Aichi Prefecture registered a high of 40.1°C. This widespread heatwave affected both eastern and western parts of Japan, with 255 out of the country’s 914 weather observation stations reporting temperatures of at least 35°C by mid-afternoon, illustrating the extreme heat enveloping the nation.
In light of these severe weather conditions, the Environment Ministry and the Japan Meteorological Agency responded by issuing heatstroke alerts across 42 prefectures, the most extensive warning of its kind this year. Such measures were deemed necessary to combat the risks posed by the oppressive heat, as authorities called on residents to take precautions such as utilizing air conditioning, maintaining hydration, and replenishing salt intake to prevent heat-related illnesses.
The conditions highlight the ongoing challenges posed by extreme weather patterns in the country, with the need for vigilance and preparedness becoming increasingly critical. The repeated occurrence of such high temperatures underscores the importance of public awareness and adherence to safety recommendations during these dangerously hot periods.
