Business and operating structure
Sompo Holdings, Inc. is the holding company. Sompo Japan Insurance is the principal domestic P&C carrier, Sompo Himawari Life serves domestic life customers, and overseas insurers form a separate reported business. Nursing-care and wellbeing operations broaden the group beyond underwriting.
Key insurance activities
Domestic P&C spans motor, fire, marine and commercial cover; domestic life focuses on protection and health-related products. Overseas operations add commercial and specialty risks in several markets. Nursing care contributes service revenue and operating characteristics that should not be treated as insurance premium activity.
Scale and current reporting context
The group reports in yen for the year ending 31 March. FY2025 results for the year ended March 2026 provide the current consolidated IFRS frame. Earlier Japanese-GAAP periods may not be directly comparable without the reconciliations supplied by Sompo.
Legal-entity, brand and subsidiary distinctions
Sompo Holdings is not the same entity as Sompo Japan or Sompo Himawari Life. Domestic P&C, overseas insurance and wellbeing are segments rather than licensed companies. Parent issuer ratings and operating-insurer strength opinions also concern different obligors.
Capital, ratings and regulatory context
Japan's economic-value solvency disclosures identify their effective date and group perimeter; they should not be backfilled into earlier periods. Overseas subsidiaries remain locally regulated. Comparison must state accounting basis, March year-end, segment mix and whether nursing-care activity is included.
What matters when comparing Sompo Holdings
For Sompo Holdings, comparison turns on the IFRS transition, economic-value solvency and non-insurance wellbeing activity.
