Aflac earns revenue primarily from supplemental insurance premiums sold through two segments: Aflac Japan and Aflac US. Japan is the larger segment by revenue (about 58% of 2025's roughly $17.2 billion total, narrowing from 64% in 2024) and historically the far more profitable one, contributing more than 70% of pretax adjusted earnings thanks to strong brand loyalty to Aflac's cancer and medical insurance products in a market with limited competition in that niche. Aflac US, built around worksite and voluntary benefits sold through employers, brokers, and digital enrollment, generates the remaining share and has been the company's primary growth focus as Japan's aging, slower-growing insurance market matures. The company's largest acquisition, ALICO Japan's life insurance operations bought from AIG for about $1.5 billion in 2010, added more than $3 billion of annual premium and cemented Aflac's position as the leading foreign life insurer in Japan. Aflac invests its float -- premiums collected before claims are paid -- across bond-heavy portfolios, giving investment income an outsized role in profitability alongside underwriting. Aflac's Japan business benefits from a distribution model built over five decades around bank partnerships and dedicated sales agencies, a network that would be extremely costly for a new entrant to replicate, giving Aflac durable market leadership in Japanese supplemental cancer and medical insurance even as the broader Japanese insurance market matures slowly. The company's investment portfolio, weighted toward Japanese government bonds and other yen-denominated fixed income to match its yen-denominated liabilities, also means Aflac's reported results are sensitive to yen-dollar exchange-rate movements independent of the underlying insurance business performance.
