Our insurance practice covers a full range of practice areas within the insurance industry, including insurance regulatory matters and insurance transactions (including reinsurance transactions), corporate transactions of insurance companies (including M&A transactions), insolvency cases, insurance coverage advice, and litigation and dispute resolution.

Insurance regulatory matters

We advise on a wide range of insurance regulatory matters including applications for insurance business licenses, sales regulations (including bancassurance regulations), the establishment of compliance systems for insurance companies and insurance agencies, and responses to inspections by supervisory agencies. Many of our attorneys have worked at the Financial Service Agency (FSA) and we have experience in requesting the FSA to amend regulations on behalf of clients. To ensure our clients are kept up to date, we promptly provide our clients with information on amendments to the insurance regulations.

Insurance-related transactions (including reinsurance transactions)

We advise on various types of insurance and reinsurance trading, including advising on insurance contracts and the drafting of reinsurance contracts and other insurance trading documentation, and the formation of captive insurance using offshore jurisdictions. With this range of experience, we are able to offer our clients truly practical advice and outstanding service.

Corporate transactions

Our attorneys have advised clients in many large-scale insurance M&A transactions. With highly-specialized attorneys practicing in each area, we offer a broad range of legal services relevant to insurance companies in the areas of M&A, demutualization, the incorporation of branches of foreign insurance companies, the transfer of insurance contracts and establishment of an insurance holding company. Recently, we have had the opportunity to handle a number of cross-border M&A transactions, both inbound and outbound.

Insolvency cases

Attorneys from our firm have served as Insurance Administrators for Toho Mutual Life Insurance Company, Daihyaku Mutual Life Insurance Co., Ltd. and Taisho Life Insurance Co., Ltd., and Deputy Trustees for Taisei Fire and Marine Co., Ltd. Our attorneys have extensive experience in handling insolvency cases for insurance companies in Japan.

Insurance coverage advice

We represent insurance companies in relation to insurance claims made by policyholders and/or beneficiaries to provide advice to the client on interpretation of the terms and conditions of insurance policies and negotiation with policyholders.

Litigation and disputes

We have an impressive record of achieving excellent results for our clients in litigation matters of every kind, such as insurance coverage and tax disputes concerning insurance policies. We also deal with disputes and litigation for policyholders whose liabilities are covered by policies issued by insurance companies.
