Widespread rainfall has been experienced across various regions in Japan, sparking a conversation about its potential impact on existing water shortages. The timing and intensity of rainfall events are under consideration by experts, who are analysing whetehr enough rain has fallen to begin to alleviate the pressing drought conditions that several parts of the nation have been experiencing over the past months. Discussions also focus on the broader context of ongoing climate changes.

Japan's geographical features, including its many mountain ranges, often lead to different weather patterns in various regions. Water shortages in certain areas, particularly during summer, are not unusual and are a cause for concern among citizens and authorities. With the advent of more severe climate changes, discussions on water management and coping strategies for these types of environmental challenges have intensified.

Just as in Japan, both the US and EU experience regional variability in terms of rainfall and climate conditions. However, water management strategies may differ. In Europe, for instance, transnational river basin management is an established practice, while the US often relies on reservoirs and large-scale water transport projects. Climate change and its effects on weather patterns is a global concern and is similarly treated with urgency in the US and EU.
