Check a Japanese business in JP-Verify by its qualified-invoice registration number (T + 13 digits) or its 13-digit Corporate Number (法人番号). Returns the invoice-registration status (registered, expired, revoked or not_registered) with its dates, the Corporate Number, and for companies the Japanese name and address with an English rendering (name_en_source 'official-en' = filed by the company; 'generated' = machine romanisation, not authoritative). Sole proprietors: number, status and dates only. Source: the National Tax Agency's published data as served by JP-Verify; JP-Verify's attribution and data_as_of fields are kept as sent. Not tax advice. One metered lookup; a malformed or mistyped number is rejected without a call.

The same check as verify_japanese_company for many numbers in one call: up to 100 per call on the key-less sandbox and Starter keys, 500 on Growth, 1,000 on Reseller. Malformed or mistyped numbers come back under invalid and are not charged; each well-formed number is one metered lookup. Large batches give large outputs. Source: the National Tax Agency's published data as served by JP-Verify (attribution kept). Not tax advice.

Major shareholders (「大株主の状況」, about the ten largest holders) that a Japanese company published in its annual or semi-annual securities report on EDINET, from JP-Verify, by Corporate Number. Holders are named only when they are organisations; other holders are reported without names, normally as an aggregate (count and combined ratio). A company that files no such report gets status no_public_disclosure: a statement of why nothing is published, not a claim that it has no shareholders. Facts as filed at the filing's basis date; not an ownership or control determination. One metered lookup. If JP-Verify has not enabled this route yet, the tool says so.

Find candidate Corporate Numbers (法人番号) for a Japanese company name (kanji, kana, romaji or the company's registered English name) with JP-Verify's deterministic matching (rule-based exact keys, not fuzzy search). Candidates carry prefecture and city to tell same-name companies apart; a name match is not proof of identity, so confirm the candidate, then call verify_japanese_company. Corporations only. One metered lookup; an empty candidate list is a valid answer.
