# 日新火災海上保険


## Wiki route

This entry sits under [[non-life-insurers/INDEX|non-life-insurers INDEX]]. Read it against [[non-life-insurers/tokio-marine-nichido-fire|東京海上日動火災保険]] for peer / contrast context and [[insurance/INDEX|insurance index]] for the broader system / regulatory boundary.

## TL;DR

日新火災海上保険株式会社は、金融庁の損害保険会社免許一覧に掲載される non-life insurer。[[non-life-insurers/tokio-marine]] group adjacency を持つが、[[non-life-insurers/tokio-marine-nichido-fire]] and [[non-life-insurers/tokio-marine-direct]] とは別の legal entity and operating-company anchor として扱う。

| License route | Insurance Business Act non-life insurance company; FSA non-life insurer list |
| Protection scheme | Non-Life Insurance Policyholders Protection Corporation member |
| Group boundary | Tokio Marine group adjacency |

## 2. Operating model

日新火災は、Tokio Marine group の main non-life brand と direct brand とは違う operating surface を持つ。SME / regional / agency channel, niche products, and group-brand segmentation を見る時に standalone page が必要になる。

- Complements [[non-life-insurers/tokio-marine-nichido-fire]] and [[non-life-insurers/tokio-marine-direct]].
- Registry-backed D5 specialty non-life page.
