Japanese Translation Services — Certified Japanese Translation

Does a koseki translation need to be certified for USCIS?

For a USCIS filing, 8 CFR 103.2(b)(3) requires a Japanese-language koseki to be accompanied by a full English translation that the translator has certified as complete and accurate, plus a certification by the translator of competence to translate Japanese into English. 8 CFR 103.2(b)(3) does not mention notarization. Corpus does not notarize. Corpus Localization includes a signed Certificate of Accuracy with its certified Japanese-to-English translations.

Corpus Localization LLC serves NY/NJ and is an ATA corporate member #M-189351. We provide document translation, not notarization, apostille, interpreting, or legal advice. For more on the submission requirement, see USCIS translation services.

How much does koseki translation cost?

A koseki up to 4 pages is an eligible standard document at $19.99/page. A register copy longer than 4 pages gets a quote review. Send the family-register file so the price is confirmed before work begins. See certified translation pricing.

How long does certified koseki translation take?

Koseki turnaround depends on the file’s eligibility; request review if that is uncertain. Our standard-document policy covers birth, marriage, divorce, academic, and police records, up to 4 pages each: delivery within 24 hours of order confirmation on business days, or that document is free. This policy does not automatically qualify every family register. Include your deadline when requesting a quote.

Can I order now, or does my koseki need a quote first?

Start your order if your file is confirmed eligible as a standard document, readable, and has a known page count. Request a quote if eligibility is uncertain or your koseki includes multiple pages or family members, older handwriting, unclear images, dense stamps or seals, back-side text, or recipient-specific instructions. Include any mixed document set and deadline for review.

Koseki translation FAQs

Does the translator have to hold ATA certification?

No. 8 CFR 103.2(b)(3) does not prescribe ATA certification, ATA membership, or a government translator license. The distinction is between certifying the Japanese-to-English translation and requiring a particular professional credential. Corpus’s ATA corporate membership is not an individual translator certification. The USCIS translation requirement is explained in the lead answer above.

What is koseki tohon in English, and how is it different from koseki shohon?

Koseki tohon means the full Japanese family-register record, covering all family members in that register. Koseki shohon is the record for one individual family member. The Consulate-General of Japan in Seattle explains this distinction and advises checking the application’s requirements before requesting either version. For related service information, see koseki translation.

Do I need the full koseki translated or just my entry?

For USCIS, translate the entire Japanese-language document you submit—not only your entry within that document. If you submit a koseki tohon, its translation must cover that document in full. This follows the full-English-translation rule in 8 CFR 103.2(b)(3); it does not decide whether your application needs a tohon or a shohon.

Send all pages of the record for translation, including headings, annotations, stamps, seals, and any back-side text. Check your application instructions or ask your legal adviser which civil record to obtain before ordering translation.

Expert Japanese Translation — Accuracy Across Three Writing Systems

Japanese documents may combine kanji, hiragana, and katakana, along with names written in the Latin alphabet. A certified translation should keep names, dates, record labels, annotations, stamps, seals, and handwritten entries consistent across the full file.

Corpus provides Japanese-to-English and English-to-Japanese certified document translation with a signed Certificate of Accuracy. Common files include koseki tohon and koseki shohon family-register records, juminhyo residence certificates, diplomas, transcripts, court records, and company records. The receiving agency, court, school, credential evaluator, or other reviewer controls its own submission rules.

If a passport or recipient-approved spelling shows a person’s name in the Latin alphabet, upload it with the Japanese source. Corpus can use that spelling when the documents clearly refer to the same person. The source still controls dates, family relationships, registry status, and other factual content.

What to Send for a Japanese Certified Translation Quote

If you arrived from search or an AI assistant, you may already know you need a certified Japanese translation but not exactly which pages count. For most Japanese documents, send the complete visible record rather than cropping to one line item.

  • For USCIS purposes: upload the full koseki tohon or koseki shohon, including municipal headings, names, dates, seals, and notes.
  • For academic evaluation: upload the diploma, transcript, grading legend, and any certificate pages from the Japanese school.
  • For legal or court use: upload all pages of the judgment, registry, power of attorney, or supporting exhibit so terminology stays consistent.

Understanding Japanese Document Systems

For Japanese civil records, check the receiving organization’s current application instructions to identify which record to obtain and submit. Do not choose a record solely because it is described as a birth certificate or family register on this page. Corpus provides translation, not legal advice about which document your application requires.

For a Japanese record translation quote, upload the complete record you intend to submit, including every page and any reverse side bearing text. Include seals, annotations, and handwritten additions in the scan, along with any translation instructions from the recipient. If a date or entry is unclear, provide a clearer copy or seek clarification from the issuer; source details must not be guessed.

Most Common Japanese Translation Requests

Koseki tohon for USCIS purposes — Check the current application instructions for the record you need to submit. For a koseki translation quote, upload the complete record you intend to submit, including every page and any reverse side bearing text. We translate the complete submitted record, including its annotations, dates, seals, and administrative notes, not selected entries. Quote review confirms scope, legibility, pricing, and turnaround; no typical page count is assumed.

Japanese university diplomas for credential evaluation — WES, ECE, and other evaluation agencies often require certified English translations of Japanese diplomas and transcripts. We translate institutional seals, program names, grading notations, and era-year dates.

Japanese marriage and divorce records — Follow the receiving organization’s instructions for which record to submit. We translate the complete submitted record, not only the entries about marriage or divorce. Include every page and any reverse side bearing text, including annotations, stamps, and seals.

Corporate documents for U.S. business filings — Company registration certificates (touki bo tohon), articles of incorporation, powers of attorney, and financial statements for business filings and corporate records.
