How this service works

Japanese billing-invoice OCR, local validation, and NTA issuer resolution. Checks dates, amounts, tax, T-number, and completeness; compares or fills issuer name and address. Phone remains OCR-only. Supports text, HTTPS URL, Base64, PDF, HEIF, and TIFF. / 日本語請求書OCR・ローカル検証・国税庁発行者照合。日付・金額・税額・T番号・必須項目を検証し、発行者名・住所を照合・補完します。電話はOCR値のみ。text、HTTPS URL、Base64、PDF、HEIF、TIFFに対応します。

Output

Returns structured OCR-extracted invoice fields (dates, amounts, tax, T-number, issuer name, issuer address, phone) alongside per-field validation results (pass/fail/warning), T-number format and checksum status, NTA-resolved issuer name and address (compared or filled against OCR values), and an overall completeness assessment. Phone number is returned as OCR value only without NTA cross-reference.

Example use cases

AP team invoice compliance check

“I've got a scanned Japanese invoice from a new supplier — can you extract all the fields from this HEIF image, validate the T-number and tax amounts, and confirm the issuer name and address match the NTA records?”

Automated accounting pipeline ingestion

“We're processing this Japanese billing invoice as a PDF — please OCR it, run all the local validation checks on dates, amounts, and required fields, and resolve the issuer details from the NTA so we can post it to our accounting system.”

Qualified invoice eligibility verification

“Before I pay this invoice, can you check whether it's a properly formatted Japanese qualified invoice? Here's the HTTPS URL to the image — verify the T-number is valid, the tax is correctly stated, and nothing required is missing.”

Endpoint

When to prefer

Choose this endpoint when you need a full end-to-end pipeline: OCR extraction plus local validation plus NTA issuer resolution in a single call. Use it over the OCR-only sibling when you also need T-number verification and issuer name/address cross-referencing, and over the issuer-check-only sibling when you don't already have clean structured invoice data and need raw document processing as well. Ideal for accounts payable automation, compliance workflows, and qualified invoice (適格請求書) validation in Japan.

Side effects

Invalid or unreadable image/PDF — OCR fails, returns error with no extracted fields
T-number not found in NTA registry — returns OCR value with NTA resolution status as unresolved
Unsupported file format — returns 400-level error
HTTPS URL inaccessible or returns non-image content — fetch failure error
Malformed Base64 input — decoding error returned
Invoice in non-Japanese format — fields may not map correctly to Japanese invoice schema
Network timeout to NTA — issuer resolution may be partial or skipped
