Japan has recorded two new all-time highs for a 24-hour period, with temperatures soaring to 41.6C (106.8F) and then 41.8C (107.2F). The mercury in the city of Isesaki, located in southern Gunma Prefecture, surpassed the previous record seen in western Hyogo region last week.
The country’s Meteorological Agency has warned that temperatures may continue to rise further. Last month was declared the hottest on record since 1898, with an average monthly temperature 2.89C above the 1991-2020 average. Heatstroke alerts were issued in 44 of Japan’s 47 prefectures.
Experts say climate change is behind the erratic weather patterns and warmer temperatures. Cherry trees are blooming earlier due to the warmer climate, while Mount Fuji’s snowcap was absent for the longest recorded period last year.
Japan is not alone in its heatwave; neighboring South Korea also experienced its second-hottest July, with an average temperature of 27.1C (80.8F). Western Europe saw its hottest June on record, with daily average temperatures climbing to levels rarely seen before.
Japanese officials urge the public to take precautions against heatstroke, staying hydrated and avoiding outdoor activities during peak heat hours. The elderly are particularly at risk due to Japan’s aging population.
