# 東京海上日動あんしん生命保険


## Wiki route

This entry sits under [[life-insurers/INDEX|life-insurers INDEX]]. Read it against [[life-insurers/dai-ichi-frontier-life|第一フロンティア生命保険]] for peer / contrast context and [[insurance/INDEX|insurance index]] for the broader system / regulatory boundary.

## TL;DR

東京海上日動あんしん生命保険株式会社は、[[non-life-insurers/tokio-marine]] group の life-insurance operating company。[[non-life-insurers/tokio-marine]] は non-life major として有名だが、本 entity は金融庁 life-insurer list に載る separate life underwriter であり、life / non-life cross-sell and group diversification を見るうえで重要。

## 1. License / group boundary

The following table is scoped to public primary sources (fsa.go.jp, seiho.or.jp, tmn-anshin.co.jp). It restates licence / structure / product boundaries from those materials and does not invent market share, ranking, or unstated numerical claims. ^[source:fsa.go.jp; seiho.or.jp; tmn-anshin.co.jp]

| Item | Notes |
|---|---|
| Legal name | 東京海上日動あんしん生命保険株式会社 |
| License route | Insurance Business Act life-insurance company; FSA life insurer list |
| Industry body | Life Insurance Association of Japan member |
| Group boundary | [[non-life-insurers/tokio-marine]] life-insurance operating company |
| Wiki role | Tokio Marine group's life-insurance underwriting arm |

## 2. Operating model

Tokio Marine group は global non-life insurance の規模が大きいが、日本国内では life products も group ecosystem の一部になる。東京海上日動あんしん生命は、この life-insurance underwriting boundary を担う entity として、[[life-insurers/sompo-himawari-life]] や MS&AD group life arms と比較する。

Non-life group による life-insurance business は、代理店 network, customer relationship, protection-product cross-sell, capital allocation の観点で traditional life insurers と違う。

## 3. Why this page matters
