Technical details
Endpoint
GEThttps://api.kasanegi.com/v1/local/invoice/issuer-registration-lookupWhen to prefer
Use this endpoint when you need to verify a Japanese supplier or vendor's qualified invoice issuer (適格請求書発行事業者) status for consumption tax compliance purposes, especially before processing invoices or onboarding new vendors in Japan. Prefer this over scraping the NTA website directly.
Side effects
- Registration number not found — returns empty or 404-equivalent result
- Invalid T-number format — returns validation error
- NTA registry temporarily unavailable — upstream timeout or 503
- Non-Japanese registration number format supplied — bad request error
