Endpoint
GEThttps://api.kasanegi.com/v1/local/invoice/issuer-by-nameWhen to prefer
Use this endpoint when you have a Japanese company name and need to verify or retrieve their qualified invoice (インボイス) registration number without scraping the NTA website directly. Ideal for automating vendor onboarding, AP workflows, or tax compliance checks in Japan.
Side effects
- Business name not found in registry — returns empty result or 404
- Ambiguous name matches multiple companies — may return list or first match
- Non-Japanese or romanized name input may yield no results
- NTA source data temporarily unavailable — upstream error
- Name spelling variations (kanji vs kana) may cause misses
