Japan faces a looming threat from climate change, with its meteorological agency warning that extreme heatwaves could become a yearly occurrence. A report released recently suggests that if global temperatures rise by 4 degrees Celsius, Japan could see what used to be rare, “once-in-a-century” heat events happen 99 times a century. This is almost 6 degrees hotter than pre-industrial times.
The report, “Climate Change in Japan 2025,” created by the Japan Meteorological Agency and the Ministry of Education, builds on a study from 2020. It reveals that Japan’s average temperature is currently increasing by 1.4 degrees every century, from 1898 to 2024. This steady rise is concerning as it aligns with a global trend of warming.
The report emphasizes the growing number of extremely hot days in Japan. Days where temperatures reach 35 degrees Celsius are now more common. Similarly, days exceeding 30 degrees are on the rise, referred to as “true summer days.” For context, two record-breaking heatwaves in July 2018 and July 2023 were attributed directly to global warming, highlighting how climate change is influencing severe weather patterns.
Additionally, if global temperatures rise as projected, Japan could see an extra 17.5 “extremely hot days” each year. Conversely, there would be approximately 46 fewer days where temperatures drop below freezing. This data highlights just how drastically climate change could reshape the climate in Japan.
Experts warn that without immediate action, the repercussions could be dire not only for Japan but for the entire planet. Recent surveys show that a large majority of people are concerned about climate change and its effects. Social media discussions reveal a growing desire for sustainable practices and policies, prompting governments to rethink their strategies.
Understanding the historical context is crucial. The climate challenges we face today are unprecedented compared to previous decades. For example, the rise in average temperatures and the frequency of extreme weather events were much less noted in earlier years.
