2. Operating model

Japan’s residential earthquake insurance is not a normal private-only catastrophe product. Primary insurers including Tokio Marine & Nichido Fire Insurance, Mitsui Sumitomo Insurance, and Sompo Japan Insurance cede earthquake risk into a public-private reinsurance structure described at natcat reinsurance Japan, and 日本地震再保険 sits at the operational center of that scheme.
