This study compares two ransomware incident reports: the City of Dallas, the U.S. (2023), and a hospital in Okayama, Japan (2024). Although both are incident reports, their structure and content differ significantly. Meanwhile, the United States and Japan have distinct domestic policy environments, yet their temporal proximity ensures comparable technical conditions and a shared global policy context. Dallas emphasizes strategic risk management and recovery outcomes, whereas Okayama focuses on causal investigations and structural corrections. Viewing incident reports as cultural artifacts, this study shows how reporting formats embody governance philosophies and proposes international standards for resilience and accountability by integrating transparency with reform-oriented practices.
