Learning from Megadisasters: A Decade of Lessons from the Great East Japan Earthquake Format Authors: Shoko Takemoto, Naho Shibuya, and Keiko Sakoda Today marks the ten-year anniversary of the Great East Japan Earthquake (GEJE), a mega-disaster that marked Japan and the world with its unprecedented scale of destruction. This feature story commemorates the disaster by reflecting on what it has taught us over the past decade in regards to infrastructure resilience, risk identification, reduction, and preparedness, and disaster risk finance. Since GEJE, the World Bank in partnership with the Government of Japan, especially through the Japan-World Bank Program on Mainstreaming Disaster Risk Management in Developing Countries has been working with Japanese and global partners to understand impact, response, and recovery from this megadisaster to identify larger lessons for disaster risk management (DRM).
