Sompo Holdings needs an entity-specific source guide. Sompo combines domestic and international P&C insurance with domestic life insurance and a material wellbeing/nursing-care platform. Its FY2025 switch to IFRS and economic-value solvency transition add a useful methodology dimension, while its parent and operating-insurer ratings require precise entity handling. The canonical company surface is the Sompo Holdings profile, while the references archive is the source-card record.
Article Intelligence
- Primary company: Sompo Holdings.
- Entity type and home jurisdiction: Listed Japanese insurance holding company with P&C, life, international insurance, nursing-care, and related operations; Japan.
- Source-pack depth: 6 cards across 6 categories.
Why This Source Map Is Distinct
Sompo's current source surface is stable and directly accessible: the FY2025 results page, annual report, ratings table, solvency library, corporate profile, and JPX document all returned HTTP 200. The solvency library explicitly records a regulatory-methodology transition and delayed FY2025 full-year group disclosure. Together, the cards establish a route from identity and business scope to periodic reporting and capital, regulatory, ratings, exchange, or profile context. They do not merge those source types into one universal measure.
Reading The Source Categories
1. Integrated Annual Report 2025
Owner: Sompo Holdings. Category: Integrated Annual Report 2025. Reporting period: Integrated Annual Report 2025; principally FY2024, year ended 2025-03-31.

Reporting Periods And Company-Specific Facts
The source cards above contain the pack's principal numerical evidence from Integrated Annual Report 2025, Overview of FY2025 results, Consolidated solvency-margin disclosure library. Each fact remains inside its complete reporting-period and entity-scope record rather than being detached into a current-value table. Units, currencies, denominators, statutory or non-statutory labels, and issuer-defined terminology must remain exactly as the applicable card records them.
Entity Boundary
Treat Sompo Holdings as the listed parent and consolidated group. Keep Sompo Japan Insurance, Sompo Himawari Life, Sompo International operating insurers, Sompo Care, other wellbeing businesses, and separately licensed subsidiaries mapped to their own legal or reporting scopes. Sompo Holdings is the parent, not Sompo Japan, Sompo Himawari Life, Sompo International, or Sompo Care. Group IFRS results, operating-insurer ratings, segment measures, and regulatory capital disclosures must not be transferred across those boundaries. No FY2025 full-year solvency ratio should be stated before the planned disclosure is published and reviewed. The guide therefore keeps the parent, consolidated group, operating insurers, brands, branches, joint ventures, and non-insurance businesses separate whenever the dossier identifies those distinctions.
What The Pack Can And Cannot Establish
The pack can establish the owner, category, URL, period, scope, and recorded facts for each card. It cannot establish current pricing, product suitability, underwriting capacity, ranking, security value, private terms, or a standalone solvency conclusion.
