Four major Japanese life insurers, including Nippon Life Insurance, reported higher revenues in fiscal 2025, driven mainly by stronger sales of yen-denominated single-premium whole life insurance policies.

The products have become increasingly attractive to consumers after insurers raised their prospective yields in response to higher long-term interest rates following the Bank of Âé¶¹´«Ã½ interest rate hikes.

Under single-premium whole life insurance policies, policyholders pay the entire premium in a lump sum when signing the contract. Upon the policyholder¡¯s death, the bereaved family or other designated beneficiaries receive insurance benefits. In many cases, policyholders use large sums of money, such as retirement allowances, to pay the premium.
