Look up one Japanese (JP) company by its 13-digit corporate number (法人番号) — official trade name (Japanese and registered English), registered address, postal code, corporation kind, and lifecycle status. `status` is "active" or "closed"; a closed record carries the closure cause/date and the successor's 法人番号 after a merger. Sourced from the 国税庁 (National Tax Agency) corporate-number public dataset. The leading check digit is validated before lookup.

Dataset metadata for this Japanese (JP) corporate-number API — how many corporations are loaded and which prefectures are covered.

Reconcile a company name (+ optional address) against the official Japanese (JP) corporate registry — the 名寄せ / KYC endpoint. Returns ranked candidate 法人番号 with a 0-1 confidence score, handling 株式会社 / (株) / ㈱ spelling variation and matching Japanese or English names. A dissolved corporation is never reported as `verified` even on an exact name match — check `best.corporation.status`. Use it to confirm a vendor, customer, or invoice counterparty.
