Heavy rainfall has triggered flooding in various underground car parks across Japan, raising concerns about the lack of evacuation plans for these areas. Consequently, public officials and experts are urgently discussing solutions. The main discussion points are a lack of preparedness infrastructure and the necessity to adopt proactive measures to ensure public safety in the face of unpredictable weather patterns, potentially intensified by climate change.

This issue has stirred heightened urgency and concern among the Japanese public. Japan frequently experiences extreme weather conditions, with structures such as underground car parks often suffering the brunt of such events. Japanese society places a high value on disaster preparedness and safety, hence the call for comprehensive evacuation plans reflects these societal values.

In comparison, flooding in underground structures is also a prevalent concern in the US and EU. Several cities have comprehensive disaster management systems including evacuation plans for such situations. Lessons learned from incidents like the recent flooding in New York's subway system or similar underground flooding events in Europe, highlight the benefits and necessity of proactive preparedness measures to mitigate risks.
