Get Company Subsidiaries

Subsidiary registry from a parent's annual 関係会社 disclosure.

Each row carries the disclosure verbatim plus derived attributes: - country (ISO 3166-1 alpha-2 from the address) - currency (ISO 4217 alpha-3 from the capital cell) - relationship_type (consolidated_subsidiary / equity_method_affiliate / parent / other_related) - cross_validation: bidirectional confirmation status when the subsidiary itself files its own annual. Filter by cross_validation='bidirectional_confirmed' for the highest- provenance edges; voting_pct_mismatch surfaces filing-lag and in-flight-restructuring signals. - holdings_filing_count + joint_filing_partner_count: cross-source evidence the entity is a real legal entity actively operating.

Built from the v3 entity-resolution output (entity_resolution_v3 parses 関係会社 disclosures with full provenance back to source XBRL tables and rows).
