# ミュンヘン再保険日本支店

## Wiki route

This entry sits under [[non-life-insurers/INDEX|non-life-insurers INDEX]]. Read it against [[non-life-insurers/toa-reinsurance|トーア再保険]] for peer / contrast context as a Japanese domestic reinsurer, and [[insurance/natcat-reinsurance-japan|nat-cat reinsurance Japan]] for the broader system / regulatory boundary. The Japan branch is one channel through which global reinsurance capacity reaches Japanese primary insurers, and it sits alongside [[non-life-insurers/japan-earthquake-reinsurance|日本地震再保険]] in the wiki's reinsurance map.

## TL;DR

ミュンヘン再保険会社（Munich Reinsurance Company / Münchener Rückversicherungs-Gesellschaft, DAX 上場）の日本支店。**世界最大級の再保険会社** の Japan branch として、金融庁の損害保険会社免許一覧（外国損害保険会社等）に掲載される。日本の元受損保（[[non-life-insurers/tokio-marine-nichido-fire]] / [[non-life-insurers/mitsui-sumitomo-insurance]] / [[non-life-insurers/sompo-japan-insurance]] 等）と生保のリスクをグローバル資本で吸収する役割を担い、特に巨大自然災害（地震・台風・水害）と生保長寿リスクの引受で重要。
