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.
