Japan’s climate is changing rapidly, and the future looks concerning. The Meteorological Agency recently projected that if we don’t take action, Japan’s average surface temperature could rise by 4.5 degrees Celsius by the end of the century. This startling prediction is part of a report called “Climate Change in Japan 2025,” which looks at temperature, rainfall, and sea surface conditions.
Since 1898, Japan’s average temperature has already increased by 1.4 degrees every century. Even more troubling, the seas around Japan have seen a drop in dissolved oxygen levels, a key indicator of global warming, falling faster than the global average in some areas. Moreover, the warming of sea surface temperatures around Japan is outpacing worldwide trends.
The report highlights that without action to control temperature increases, Japan could face severe climate changes. If current trends continue, we could see an increase of about 17.5 extreme hot days annually, along with a reduction of 46.2 winter days by 2100. It also suggests that while there may be fewer rainy days overall, heavy rainfall events will become more common. Projections indicate that if the temperature rises by 4 degrees Celsius, such intense rainfall events could triple.
Kimio Hanawa, an honorary professor at Tohoku University and a member of the agency’s climate change advisory panel, voiced his concerns at a recent news conference. He pointed out that 2023 and 2024 were exceptionally warm years for Japan. "Climate change is an extremely important and urgent issue that humanity faces globally," he emphasized.
To give a clearer picture of the urgency, consider this: a 2023 report from the Intergovernmental Panel on Climate Change (IPCC) stated that globally, climate-related disasters have increased by 83% since 2000 due to rising temperatures. This emphasizes not just a local issue but a worldwide crisis that requires immediate attention.
The trends we see today are not new; similar patterns have been observed in the past, making this report a sobering reminder of the long-term consequences of inaction. Addressing these issues seriously could help Japan navigate the challenges ahead and potentially inspire other countries to take similar steps.

Understanding these changes is crucial for all of us, as they impact not only the environment but also our health, economy, and way of life. Each small action counts, and staying informed is our first step toward making a difference.
