# ハノーバー再保険日本支店

## Wiki route

This entry sits under [[non-life-insurers/INDEX|non-life-insurers INDEX]]. Read it against [[non-life-insurers/munich-re-japan|ミュンヘン再保険日本支店]] and [[non-life-insurers/swiss-re-japan|スイス再保険日本支店]] as the "Big 2 + Hannover" trio of European reinsurers in Japan, and [[non-life-insurers/toa-reinsurance|トーア再保険]] as the domestic peer. The system page [[insurance/natcat-reinsurance-japan|nat-cat reinsurance Japan]] frames how all of these fit into Japan's catastrophe risk transfer architecture.
