TL;DR

The only local non-life insurance company in Okinawa Prefecture. Established as “Okinawa Marine and Fire Insurance” in Okinawa under 1951-04 US military administration, it was the sole Japanese-registered non-life insurer in postwar Okinawa. With 1972 年 Okinawa’s reversion to mainland Japan it became treated as a domestic Japanese non-life insurer, and 1985 年 it was renamed to its current name “Daido Fire and Marine Insurance”. From the 2000 年s onward, it covered a nationwide network through a business alliance with Sompo Japan (now sompo). No.1 in non-life insurance share within Okinawa Prefecture, specializing in tourism insurance (travel accident / rental car / guesthouse liability) and typhoon / remote-island reinsurance schemes. It maintains a local advantage under competition from the major 3 non-life insurers’ (tokio-marine / msad / sompo) Okinawa bases. Unlisted. ^•
