Japan non-life insurer registry index

TL;DR

FSA’s non-life insurer license list (損害保険会社免許一覧, songai.pdf) is the single registry surface for every entity licensed under Japan’s Insurance Business Act (保険業法) to underwrite non-life (損害) insurance. This page is the routing surface for that registry — it organises the list by ownership cluster (大手3社 / direct / specialty / foreign-affiliated / reinsurer) instead of forcing every page reader to interpret the raw FSA workbook. It mirrors the structure of trust-companies-japan-index and foreign-bank-branches-japan-index.

Standalone insurer pages stay in non-life-insurers INDEX. Concept pages (catastrophe risk, agency channel, solvency) stay in insurance. This index sits between them and routes both ways.

Wiki route

This entry sits under non-life-insurers INDEX as the non-life counterpart to trust companies registry index and foreign bank branches registry index. Read it against Japan non-life big three for the holding-company comparison layer, nat-cat reinsurance in Japan for the risk-cession layer, and insurance index for the broader operating-model map. Capital adequacy translation goes through economic value-based solvency and global solvency framework comparison matrix. Foreign-reinsurer-only entries are grouped on foreign reinsurer Japan landscape and Lloyd’s Japan syndicate operating model sister pages.

Boundary

Boundary	Treatment
Non-life direct insurer (元受損保)	Listed in this index. Promote to standalone JapanFG page when there is a clear strategic, channel, or capital story.
Reinsurer (再保険専業)	Listed here under the “Reinsurer” cluster but the cession-flow analysis lives on foreign-reinsurer-japan-landscape.
Lloyd’s syndicate market	Listed as one Lloyd’s Japan row. The marketplace structure detail lives on lloyds-japan-syndicate-operating-model and the entity page lloyd-japan.
Captive insurer	Not on this list. Japan does not have an onshore captive license, so captives live on captive-insurance-japan-market.
P&I mutual (船主相互保険組合)	Not on the FSA non-life list; it is licensed under 船主相互保険組合法. See [[financial-regulators/japan-pi-club
Holding company (持株会社)	Not on this list. See [[non-life-insurers/tokio-marine
Life insurer (生命保険会社)	Not on this list — different FSA register (seimei.pdf). See japan-life-insurance-big-four.
Insurance agency / broker	Different licensing (募集人 / 仲立人). See insurance-agency-and-brokerage-japan.

Registry snapshot

Metric	Reading
FSA as-of date	2026-04-01
Domestic non-life insurance companies (内国損害保険会社)	~30 ^[ambiguous — number shifts as direct / specialty / holding-company subsidiaries are added or merged]

The FSA file is updated on an irregular cadence; readers should always re-fetch the latest songai.pdf / songai.xlsx before treating any specific row count as final.

A. 大手3社 — domestic holding-company groups (元受)

Holding company	Domestic non-life operating company	Direct subsidiary	Specialty subsidiary
[[non-life-insurers/tokio-marine	Tokio Marine Holdings]]	[[non-life-insurers/tokio-marine-nichido-fire	Tokio Marine & Nichido Fire]]
[[non-life-insurers/msad	MS&AD Holdings]]	[[non-life-insurers/mitsui-sumitomo-insurance	Mitsui Sumitomo Insurance]] + [[non-life-insurers/aioi-nissay-dowa-insurance
[[non-life-insurers/sompo	Sompo Holdings]]	[[non-life-insurers/sompo-japan-insurance	Sompo Japan Insurance]]

B. Direct (digital / telco / EC) non-life insurers

Operating company	Distribution anchor	Cluster
[[non-life-insurers/sony-insurance	Sony Insurance]]	[[megabanks/sony-fg
[[non-life-insurers/sbi-insurance	SBI Insurance]]	[[megabanks/sbi-hd
[[non-life-insurers/au-insurance	au Insurance]]	[[megabanks/au-fh
[[non-life-insurers/rakuten-general-insurance	Rakuten General Insurance]]	[[payment-firms/rakuten-fg
tokio-marine-direct	Tokio Marine HD	Direct auto under big-three umbrella
sompo-direct	Sompo HD	Direct auto under big-three umbrella
mitsui-direct	MS&AD HD	Direct auto under big-three umbrella

Direct insurers compete on cost and customer-acquisition channel rather than tied-agency density. They are still subject to FSA non-life licensing and to the catastrophe-risk economics described in natcat-reinsurance-japan.

C. Specialty / niche / regional non-life insurers

Operating company	Specialty	Notes
[[non-life-insurers/anicom-insurance	Anicom Insurance]]	Pet insurance
[[non-life-insurers/dai-ichi-ipet-insurance	Dai-ichi iPet Insurance]]	Pet insurance
[[non-life-insurers/pet-and-family-insurance	Pet & Family Insurance]]	Pet insurance
[[non-life-insurers/yamap-naturance-insurance	YAMAP Naturance Insurance]]	Outdoor / hiking specialty
[[non-life-insurers/ntt-docomo-sonpo	NTT Docomo Insurance]]	Telco-bundled mobile / travel
[[non-life-insurers/secom-insurance	SECOM Insurance]]	Security / home / medical
[[non-life-insurers/daido-fire-marine	Daido Fire & Marine]]	Regional / commercial
[[non-life-insurers/kyoritsu-fire-marine	Kyoritsu Fire & Marine]]	Regional / commercial
[[non-life-insurers/nisshin-fire	Nisshin Fire & Marine]]	Auto / fire (Tokio Marine group)
[[non-life-insurers/meiji-yasuda-general-insurance	Meiji Yasuda General Insurance]]	Group-life-affiliated non-life
[[non-life-insurers/cardif-nonlife	Cardif Non-Life]]	Credit / loan-protection
[[non-life-insurers/capital-insurance	Capital Insurance]]	Specialty
[[non-life-insurers/sakura-insurance	Sakura Insurance]]	Specialty
[[non-life-insurers/sbi-insurance-group	SBI Insurance Group]]	Group holding
[[non-life-insurers/ji-accident-fire-insurance	JI Accident & Fire]]	Specialty accident / fire
[[non-life-insurers/zenkankyo-reiwa-insurance	Zenkankyo Reiwa Insurance]]	Specialty
[[non-life-insurers/hs-insurance	HS Insurance]]	Travel

The specialty cluster reflects a 2010s-2020s structural shift: Japan’s non-life premium has expanded into pet, outdoor, travel, mobility, telco-bundled, and EC-bundled niches that the 大手3社 cannot easily serve at their unit-cost base.

D. Foreign-affiliated direct non-life insurers (外国損害保険会社等)

FSA-listed name	Parent	Cluster
[[non-life-insurers/aig-japan	AIG Japan]]	AIG (NYSE: AIG)
[[life-insurers/axa-japan	AXA Japan]]	AXA SA (Euronext: CS)
[[non-life-insurers/allianz-fire-marine-japan	Allianz Fire & Marine Insurance Japan]]	Allianz SE (DAX: ALV)
[[non-life-insurers/chubb-insurance-japan	Chubb Insurance Japan]]	Chubb Limited (NYSE: CB)
[[non-life-insurers/hyundai-marine-fire-japan	Hyundai Marine & Fire Japan]]	Hyundai M&F (KOSPI)
[[non-life-insurers/american-home-insurance-japan	American Home Insurance Japan]]	AIG group
[[non-life-insurers/starr-insurance-japan	Starr Insurance Japan]]	Starr Companies (US)

Foreign-affiliated direct insurers operate either as branches (外国損害保険会社) or as 100%-owned Japanese subsidiaries (株式会社 with foreign parent), depending on the FSA license category — see insurance-license-and-solvency. The Lloyd’s Japan platform is treated separately because Lloyd’s is a marketplace, not a single carrier.

E. Lloyd’s Japan (marketplace platform)

Entity	Notes

Lloyd’s Japan is structurally different from every other row on this list: it is the FSA-registered local channel through which Lloyd’s syndicates write Japan-located risks, rather than a single risk-bearing carrier. See lloyds-japan-syndicate-operating-model for the syndicate-capacity model, marine / aviation / cyber / political-risk lines, and reinsurance-vs-direct boundary.

F. Reinsurers in Japan

Operating company	Parent / structure	Cluster
[[non-life-insurers/toa-reinsurance	Toa Reinsurance]]	Domestic listed (TSE)
[[non-life-insurers/japan-earthquake-reinsurance	Japan Earthquake Reinsurance (JER)]]	Public-private earthquake scheme operator
[[non-life-insurers/munich-re-japan	Munich Re Japan]]	Munich Re AG (DAX: MUV2)
[[non-life-insurers/swiss-re-japan	Swiss Re Japan]]	Swiss Re Ltd. (SIX: SREN)
[[non-life-insurers/hannover-re-japan	Hannover Re Japan]]	Hannover Rück SE (FWB: HNR1) / Talanx
[[non-life-insurers/scor-japan	SCOR Japan]]	SCOR SE (Euronext: SCR)
[[non-life-insurers/gen-re-japan	Gen Re Japan]]	General Re Corp. → Berkshire Hathaway (NYSE: BRK)
[[life-insurers/rga-japan	RGA Japan]]	RGA Inc. (NYSE: RGA)
[[life-insurers/pacific-life-re-japan	Pacific Life Re Japan]]	Pacific Life Insurance Co. (US mutual)

Reinsurers are licensed as 外国損害保険会社等 (foreign branch) or 内国損害保険会社 (domestic) under the same FSA register as direct insurers, but they do not underwrite policyholder retail business directly and are therefore excluded from the Non-Life Insurance Policyholders Protection Corporation member set (see toa-reinsurance which is the exception, being a member). The reinsurance market structure is analysed on foreign-reinsurer-japan-landscape.

Promotion / standalone rules

A non-life insurer is worth a dedicated JapanFG page when at least one of these applies:

it sits in the 大手3社 holding-company or operating-company layer;
it is a registered direct (digital / telco / EC) non-life insurer with public IR or material brand presence;
it is a foreign-affiliated insurer with a distinct Japan strategy, parent regulatory link, or specialty;
it is a reinsurer with public group disclosure;
it is a specialty insurer that creates a new product category (pet, outdoor, cyber, parametric) and is recurringly referenced in insurance / fintech / consumer-finance analysis.

A standalone page is not required for every FSA row that is captured here. Long-tail specialty rows can stay registry-only until a research question pulls them into wider analysis.

How to read this registry

Start at the holding-company layer when the question is “who is this group?” — use japan-nonlife-big-three.
Drop to the operating-company layer when the question is about underwriting entity, agency channel, or domestic merger lineage.
Use the direct / specialty cluster when comparing distribution economics or new product categories.
Use the foreign-affiliated cluster when analysing inbound capital, cross-border specialty placement, or parent-group strategy.
Use the Lloyd’s / reinsurer clusters when the question is about risk transfer, marine / aviation / cyber capacity, or catastrophe cession.
Cross-check with capital framework via global-solvency-framework-comparison-matrix when comparing across regimes — a Japan-licensed branch and its parent may sit on different solvency lenses.
