Japan Post Insurance has signed definitive agreements to invest US$2 billion (approximately ¥300 billion) in a new investment vehicle sponsored by Global Atlantic, a wholly owned subsidiary of KKR & Co. Inc.
The vehicle, in which Japan Post Insurance will hold over 50% of the capital, is expected to have access to Global Atlantic’s insurance, reinsurance, and other strategic activities. It is scheduled to begin operations in the first half of 2026, pending customary regulatory approvals.
This latest transaction builds on the strategic partnership formed in June 2023 between Japan Post Insurance, KKR, and Global Atlantic.
Private equity-backed reinsurance has been gaining ground in Asia, with assets increasing tenfold between 2019 and 2023 to about US$25 billion by year-end. Although this remains a small fraction of the overall market, analysts note that arrangements with global reinsurers offer Japanese life insurers greater access to capital and risk-transfer solutions.
Japanese insurers have also increasingly used offshore reinsurance as they adapt to a rapidly aging population and shifting capital rules, including the adoption of IFRS 17 and risk-based capital requirements. These cross-border deals provide additional flexibility for managing long-term liabilities and maintaining solvency under tighter regulatory standards.
Kunio Tanigaki (pictured above right), president and CEO of Japan Post Insurance, said the investment is part of the company’s phased approach to its alliance with KKR and Global Atlantic.
“We believe that this investment will enable Japan Post Insurance to diversify our revenue sources by capturing revenues from the robust US annuity market and reinsurance markets globally and continue to build on our win-win relationship with KKR and Global Atlantic,” Tanigaki said.
Japan Post Insurance plans to make its investment over time and expects minimal impact on its consolidated results for the fiscal year ending March 31, 2026. The company said it would issue a market disclosure if the transaction is expected to materially affect its performance.
Industry estimates suggest that as much as 30% of Japan’s roughly US$3 trillion in life insurance liabilities – about US$900 billion – could be ceded to offshore reinsurers in the coming years. Depending on individual company strategies, between US$150 billion and US$300 billion may be transferred to global reinsurance platforms.
The company has already pursued large-scale reinsurance solutions in recent years. For instance, it entered a deal with Reinsurance Group of America (RGA) to reinsure approximately ¥700 billion of in-force individual life annuities through coinsurance.
