Japan Company Enrichment — Bulk Registry Lookup & KYB Reports

Enrich a list of Japanese companies in one run, straight from the official National Tax Agency (国税庁) corporate registry covering all 5.78M registered corporations. Feed it company names and/or 13-digit corporate numbers (法人番号) — mixed input is fine — and get one dataset row per company.

What you get per company

Registry record mode (default, cheaper): official trade name, kana reading, registered address (+ postal code), corporation kind, lifecycle status (active / closed with closure cause, date, and successor after mergers), assignment/update dates.

Full KYB report mode: everything above plus kana + romaji name readings, machine-actionable risk flags (closed registry, recent registration/changes), an English summary, and the dataset vintage — a one-row due-diligence pack that replaces 3–4 separate lookups.

Company names are resolved against the registry with confidence scoring; an optional prefecture filter narrows matching. Rows that fail to match are returned with ok: false and an error message — you are not charged for failed rows.

Use cases

• Supplier / merchant onboarding (KYB) at scale
• CRM & lead-list cleanup: normalize trade names, attach 法人番号 and addresses
• Invoice-fraud and counterparty checks before payment runs
• Enriching scraped company lists with official registry data

Input

{
  "companies": ["トヨタ自動車株式会社", "7000012050002", "Sony Group"],
  "mode": "kyb",
  "prefecture": "東京都"
}

• companies — up to 200 names and/or 13-digit corporate numbers per run
• mode — record (registry record) or kyb (full report)
• prefecture — optional filter used when resolving names

Output (dataset, one row per company)
