Japanese company KYB report in one call — company lookup + verification from a corporate number or company name. Returns the official 国税庁 registry record, lifecycle status, kana + romaji name readings, risk flags (closed registry, recent registration/changes), an English summary, and the dataset vintage. Use for counterparty due diligence, supplier onboarding, or invoice fraud checks — replaces 3-4 separate lookups.
