Japan Faces “Abnormal Heat” as Summer Temperatures Soar
Tokyo – Japan is experiencing increasingly severe summer heat,with 2025 officially classified as an “abnormal heat” year by the Japan Meteorological Agency (JMA). This designation underscores a growing trend of climate disasters and aligns with a global surge in the frequency and intensity of heat waves,scientists warn.
The escalating temperatures in Japan, alongside similar warming trends in Europe, are demonstrably linked to human-induced climate change, resulting in longer and more intense summers. The United Nations recently cautioned that rising global temperatures are already impacting health and productivity,estimating potential labor efficiency declines of two to three percent for each degree Celsius above 20°C. A chart illustrating the summer temperature anomaly in Japan between 1989 and 2025 highlights the dramatic shift.
Studies confirm that the elevation of temperatures is not a natural fluctuation,but a direct consequence of climate change. Since 1990, Japan has been among the regions experiencing the most significant warming. The JMA’s classification serves as a critical warning,emphasizing the urgent need for proactive measures to mitigate the risks associated with these extreme weather events.
