# Starr Insurance Japan / スター・インシュアランス・ジャパン

## Wiki route

This entry sits under [[non-life-insurers/INDEX|non-life-insurers INDEX]]. Read it against [[non-life-insurers/aig-japan|AIG Japan]] and [[non-life-insurers/chubb-insurance-japan|Chubb Insurance Japan]] for foreign-specialty-insurer peer context, and [[insurance/INDEX|insurance index]] for the broader Japan non-life market system / regulatory boundary.

## TL;DR

Starr Insurance Companies (Starr Companies) is a global insurance and investment organization led by **Maurice R. "Hank" Greenberg**, the former CEO of AIG, with roots dating to C.V. Starr & Co. (founded in Shanghai in 1919). After Greenberg's departure from AIG in 2005, he rebuilt Starr into an independent global insurance group, including specialty property and casualty, accident and health, and aviation. Starr's Japan presence is part of its global specialty footprint, sitting alongside other specialty foreign carriers such as [[non-life-insurers/lloyd-japan|Lloyd's Japan]] and [[non-life-insurers/fm-global-japan|FM Global Japan]] for commercial and specialty risks.

## 2. Operating model

Starr Insurance focuses on specialty commercial property and casualty, accident and health, aviation, and marine. The global model emphasizes broker-led distribution to multinational clients and specialty risk segments. In Japan, Starr's distinct positioning derives from:

- **Greenberg-era specialty heritage**: Built on Hank Greenberg's leadership and longtime AIG specialty insurance playbook
- **Aviation and marine specialty**: Historic strengths reflecting C.V. Starr's 1919 Shanghai origins
- **Accident & health (A&H)**: Including travel insurance and corporate group covers
- **Mid-market and specialty commercial property and casualty**

This positions Starr Japan as a specialty alternative to [[non-life-insurers/aig-japan|AIG Japan]] (Greenberg's former group), [[non-life-insurers/chubb-insurance-japan|Chubb Insurance Japan]], and [[non-life-insurers/lloyd-japan|Lloyd's Japan]] syndicates. Solvency framework comparisons are summarized in [[insurance/global-solvency-framework-comparison-matrix|global solvency framework comparison matrix]]; the broader Japan non-life market structure is described in [[insurance/japan-nonlife-big-three|Japan non-life big three]].

## 3. Why this page matters

- Adds a registry-confirmed foreign specialty insurer with a distinctive heritage missing from JapanFG.
- Clarifies the Starr / AIG historical relationship and the post-2005 independence under Greenberg.
- Useful for understanding the Tokyo specialty insurance market, where multiple foreign carriers compete for marine, aviation, and accident & health business.
- Sets up reference for privately-held foreign insurance groups operating in Japan, where public disclosure differs from listed groups.
