Abstract: Most industrialized nations have attempted to control floods through civil engineering technologies. However, these measures have failed in the face of immense natural forces. Through allomorph analysis and expert interviews, this study examined the situation of implementing urban flood rules in major Japanese cities. The river canal in the Tokyo region is mostly maintained through infrastructure, and Tokyo has a diverse network of systems linked by rivers, canals, and drainage channels, which demonstrates its dominance in structural and civil engineering flood management. In Osaka Prefecture, flood risk management is an ongoing process built on a structural engineering foundation, and local governments continue to examine and update new policies to handle the risks and difficulties produced by ever-changing flood catastrophes. To enhance public education and awareness, local administrations in the Toyama and Chiba Prefectures are implementing programs to educate locals about flood hazards and preparation. To summarize, public engagement is an important component of flood risk mitigation and management in Japanese communities. Governments may help communities become more resilient and prepared in the face of floods by involving local residents, institutionalizing public education and awareness, and building volunteer networks. This is the conclusion reached as a result of socio-hydrological intervention.
