Japan, an island nation located in the east of Asia, is famous for its weather diversity from Hokkaido in the north to Kyushu in the south. In October 2023, several weather conditions caught the attention of the public and news readers. First, there was a tropical storm that hit western Japan, hitting Hiroshima and Okayama prefectures. This storm brought strong winds and heavy rain, causing flash floods and landslides. The local government issued an evacuation warning, advising residents to move to safer places. At the same time, in Hokkaido, the air temperature showed a drastic drop. At night, temperatures can reach freezing point, triggering an earlier than usual winter. This has attracted the attention of farmers, who are concerned about damage to vegetable crops, especially potatoes and cabbage, which are usually still in the growing phase. In the Tokyo area, despite the approaching storm, daily temperatures remained warm. The sunny weather in early October invites many visitors to enjoy the stunning views of autumn leaves. Thanks to the warmer climate, local festivals and markets are packed with visitors, welcoming the vibrant atmosphere brought by the changing seasons. One of the main concerns is the shift in extreme weather due to climate change. Scientists note that the presence of stronger storms and more frequent extreme weather in Japan could potentially be a long-term impact of global warming. Recent research shows that the average temperature in Japan has increased by about 1 degree Celsius in the last 100 years, affecting national weather patterns. The Japanese population also began to adapt to new weather conditions. For example, many homes are equipped with modern drainage systems, while farms employ hydroponic techniques to combat the threat of flooding. Increased awareness regarding the need to protect the environment and reduce carbon emissions is also getting stronger. Dynamic weather changes in Japan not only have an impact on daily life, but also on the tourism and economic sectors. The government continues to update the weather early warning system to protect the public and reduce losses. In addition, with the population becoming increasingly aware of security and disaster resilience, community participation in disaster management training is increasing. With a variety of extreme weather conditions, Japan faces complex challenges, requiring collaboration between the government, society and scientists to create long-term strategies to overcome the impacts of weather changes. This collaborative effort focuses not only on mitigation, but also on adaptation to ensure the safety and security of communities in the future.
