TL;DR
An authorized corporation for the protection of policyholders, of which all non-life insurance companies operating domestically are members. It was established with the enforcement of the 1998-12 revised Insurance Business Act. It serves as the last safety net responsible for continuing the contracts of a failed non-life insurer + paying insurance claims + assuming contracts. Its funds consist of “assessments” contributed by members and “subsidies from the government (in the case of special measures).” It responded to the wave of non-life insurer failures in the latter half of the 1990 年s through the early 2000 年s (Non-life Insurance Policyholders Protection Corporation of Japan 2000-05 / SOMPO Holdings (Sompo Holdings) 2001-11 / Mitsui Sumitomo Insurance 1996 , etc.). Its current membership is on the scale of 24 社 domestic non-life insurers. Together with the life-insurance version (Life Insurance Policyholders Protection Corporation), it forms one of the two major insurance safety nets.

2. Business scheme
| Business | Content |
|---|---|

| Financial assistance to a rescuing insurance company | A monetary grant when a rescuing insurance company takes over the failed insurance company |
| Compensation for insurance-claim payments | Compensates a certain proportion of insurance-claim rights that had already arisen at the time of failure |
| Compensation for surrender refunds, etc. | Compensates a certain proportion of surrender refunds, maturity refunds, etc. |
| Collection of assessments | Collected from member non-life insurers each fiscal year (apportioned by premium income, etc.) |
| Borrowing of funds | Borrows from financial institutions when necessary (with a government guarantee) |
Compensation levels (main lines)
| Insurance line | Compensation level |
|---|---|
| Compulsory automobile liability insurance (CALI) | 100% (top priority because it is compulsory insurance) |
| Earthquake insurance | 100% (under the government reinsurance scheme) |
| Automobile insurance (voluntary) | Accidents arising within 3 months after failure are 100%; thereafter 80% |
| Fire insurance (individual) | 80% (100% within 3 months after failure) |
| Liability insurance | 80% |
| Marine / transport / credit insurance, etc. (for enterprises) | 80% |

3. Funding structure
Revenue
├── Assessments (contributed by members 24 社, apportioned by premium income)
├── Borrowings (when necessary, with a government guarantee)
└── Government subsidy (in the case of special measures, supplementary provisions of the Insurance Business Act)
Expenditure
├── Financial assistance to rescuing insurance companies
├── Operating expenses of succeeding insurance companies
├── Direct compensation payments to policyholders
└── Operating expenses of the CorporationAssessment calculation
- Apportioned on the basis of each non-life insurer’s net premium income
- The major 4 groups (Tokio Marine / Sompo Japan Insurance / Mitsui Sumitomo Insurance / Aioi Nissay Dowa Insurance) contribute the majority
- The Corporation fundamentally does not hold a thick standing reserve fund, but is structured to respond through ex-post burden at the time of failure (the same as the life-insurance version)
4. Past rescue cases
| Date | Failed non-life insurer | Resolution scheme |
|---|---|---|
| 1996 | Taisho Marine & Fire | Rescue merger (assumed by Sumitomo Marine) |
| 2000-05 | **Non-life Insurance Policyholders Protection Corporation of Japan** | The Corporation’s first full-scale rescue (financial assistance) |
| 2001-11 | **SOMPO Holdings (Sompo Holdings)** | Corporation involvement; assumed by the Sompo Japan lineage (the former Yasuda Fire) |
| 2008 | Yamato Life (a Life Insurance Policyholders Protection Corporation case, as it is life insurance) | — |
From the middle of the 2000s onward, failure cases decreased substantially due to the management integration of mid-tier non-life insurers (the formation process of Sompo Japan Insurance / Aioi Nissay Dowa Insurance, etc.).
5. International comparison / issues
- Close to the State Guaranty Fund system under U.S. NAIC guidelines, but Japan has a single nationwide corporation (the U.S. has one per state)
- Whereas the U.K.’s FSCS (Financial Services Compensation Scheme) unifies banking and insurance, Japan keeps the Deposit Insurance Corporation, the life-insurance corporation, and the non-life-insurance corporation separate
- Review of the assessment system under climate-related risk (frequent and intensifying natural disasters)
- Development of compensation schemes in response to the expansion of new insurance lines such as cyber insurance and pet insurance
- Debate over the decline in membership and the financial base as the management integration of non-life insurers advances
