Solution Insurer-led flood risk assessment, site visits, and policy-supported resilience planning for port-adjacent assets Key challenge Port resilience is difficult because risks are systemic and interdependent across neighboring assets Context Japan’s ports are highly exposed to sea-level rise, storm surge, coastal flooding, and typhoon-related impacts, while interdependence across assets complicates incentives for individual investment Solution in practice After heavy losses at a major vehicle storage yard, Tokio Marine assessed the site’s flood risk and recommended raising ground levels. The company implemented the investment, and later experiences showed no comparable severe losses. The case also informed wider MLIT-led guidance for coordinated port resilience planning Impact / outcome Raising ground levels at the storage yard - no comparable severe losses since; informed MLIT-led port resilience guidance. Next steps Standardize port and coastal risk assessment methods, strengthen coordination across neighboring port assets and operators, and connect insurer-led analytics more directly to investment planning and public policy frameworks.
