Earthquake Resilience in Japanese Cities: Reactive and Proactive Approaches

Urban resilience to earthquakes refers to the capacity of cities to anticipate, absorb, and adapt to seismic shocks through a combination of structural, institutional, and social mechanisms. In the context of Japan, one of the world’s most seismically active countries, this concept has evolved through both post-disaster learning and anticipatory planning. This entry examines two complementary trajectories of urban resilience in Japanese cities: reactive resilience, which develops through adaptation after a destructive event, and proactive resilience, which is embedded in preventive policies and preparedness strategies before a shock occurs. The city of Kobe, following the 1995 Great Hanshin Earthquake, exemplifies a reactive trajectory shaped by institutional reform, community mobilization, and regulatory change. In contrast, Tokyo represents a proactive resilience model based on stringent seismic standards, advanced monitoring and early warning systems, and a widespread culture of disaster preparedness. By comparing these trajectories, the entry outlines a conceptual framework for understanding urban seismic resilience as a dynamic process that integrates social adaptation, governance, and technological innovation.
