The key objective is to share good practices and lessons learned from Japan with practitioners and governments working on establishing or enhancing a dam safety assurance system for further study and reflection in line with their national contexts. It was built on an earlier set of fifty-one country case studies compiled for the World Bank global comparative analysis of regulatory frameworks for the safety of dams and downstream communities (Wishart et al. 2020).en-USCC BY-NC 3.0 IGODAM SAFETY MANAGEMENTHOLISTIC SYSTEMWATER RESOURCESHYDROPOWERFLOOD CONTROLKUROBE RIVERMULTIPURPOSE DAMSSEISMIC CHANGESReportWorld Bankhttps://doi.org/10.1596/43669
