  • Contact-center AI: AI-enabling inquiries, automating policy lookups
  • US-parent digital investment: across Aflac Incorporated as a whole, expanding AI / cloud budgets (10-K disclosure)

    • Dai-ichi Life HD acquired shares equivalent to roughly 7% of US Aflac Incorporated on a voting-rights basis for long-term holding purposes (at announcement, a planned two-stage acquisition)
    • Cross-selling on the sales-staff channel (Dai-ichi Life’s sales staff handle Aflac’s cancer insurance)
    • Joint product development / joint marketing / information-system collaboration

  • Bancassurance such as Daiwa Securities / Mizuho Securities: third-sector insurance offered on the bancassurance channel (the handling companies vary by period)
  • Agency network: relationships with non-life-affiliated agencies / multi-company agencies

Overseas strategy

  • Aflac Life Insurance Japan (the Japanese company) is basically specialized in domestic Japan business
  • Global expansion is handled by the US parent Aflac Incorporated, with the US segment (workplace-sold supplemental insurance) complementing the Japan segment
  • At the US-parent level, concentration on 2 countries, the US and Japan, with limited expansion into emerging markets

B2C branding

  • Aflac Duck: a duck character that cries “Aflac!” Full rollout in the US 2000 年~, in Japan 2009 年~. In Japan, many CMs feature Toshiyuki Nishida, Aoi Miyazaki, Rina Kawaei, Shota Matsuda, Satoshi Ohno, etc.
  • “Insurance for living”: the brand slogan for cancer insurance (cancer-survivor-perspective messaging)
  • Corporate colors: Aflac blue (trust) + Aflac Duck white

4. Regulation / policy

  • Principal supervisor: Financial Services Agency (FSA) — registration / supervision based on Japan’s domestic Insurance Business Act
  • US parent: SEC / NAIC (National Association of Insurance Commissioners) / Georgia State Insurance Department
  • Insurance Business Act: third-sector insurance-product authorization, solvency-margin regulation, policyholder protection
  • International capital regulation: ICS (Insurance Capital Standard, IAIS-led) response
  • Recent policy topics:
    • IFRS 17 / international accounting standards response from 2024~ (the US parent is US GAAP, the Japan subsidiary is Japanese standards, but with an impact on group reporting)
    • New solvency regulation (economic-value-based) applied 2025-04 → valuation of a liability structure centered on the third sector
    • Sophistication of digital-complete contracts / identity verification (eKYC, Act on Prevention of Transfer of Criminal Proceeds response)
    • Principles for Customer-Oriented Business Conduct (FSA) response — strengthening agency monitoring

Competitors (domestic third-sector / medical insurance)

  • Dai-ichi Life dai-ichi-life: both an alliance partner and a competitor in the third sector (cancer-insurance / medical-insurance lineup)
  • Nippon Life nippon-life: the largest domestic life insurer, expanding third-sector share
  • Mitsui Sumitomo Aioi Life msad: MS&AD group, medical insurance as a mainstay
  • MetLife metlife-japan: foreign-affiliated, medical insurance / whole-life insurance
  • Zurich Life: strength in net direct sales of medical insurance
  • ORIX Life: focus on medical / whole-life, direct + agency
  • Sompo Japan Himawari Life (sompo-hd affiliated)
  • Tokio Marine & Nichido Anshin Life (tokio-marine-hd affiliated)

From the monopoly position of 1974~2001 , after the 2001 年third-sector liberalization it became a crowded field. Aflac maintains a No.1 -class position through its “cancer-insurance brand” and distribution-channel diversity

[!info] Verification status confidence: likely (composed solely of public information from Wikipedia + US-parent 10-K + Dai-ichi Life HD press + Aflac Japan official history, 2026-05-19 verified). Because the Japan subsidiary’s detailed financial results pass through the US-parent Aflac Incorporated’s Japan-segment disclosure, individual yen-denominated figures are subject to point-in-time variation. Dai-ichi Life’s roughly 7% on a voting-rights basis is on the planned basis at the time of the 2018-07-12 announcement; the current holding ratio requires separate confirmation.
