TL;DR

Japan Earthquake Reinsurance Co., Ltd. (日本地震再保険株式会社) is an earthquake reinsurance company listed on the FSA’s non-life insurance company license list. It is a central operating-company anchor for understanding Japan’s public-private residential earthquake insurance scheme, and the concept page is placed at natcat-reinsurance-japan.

1. License / group boundary

The following table is scoped to public primary sources (fsa.go.jp, sonpohogo.or.jp, nihonjishin.co.jp). It restates licence / structure / product boundaries from those materials and does not invent market share, ranking, or unstated numerical claims. ^↗

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.
