Certified Japanese Translation Services
Certified Japanese translation for koseki (戸籍), jūminhyo, academic credentials, and corporate filings. We handle all three Japanese scripts — Kanji, Hiragana, and Katakana — with accurate Imperial-era date conversion and name romanization for USCIS, court, and university submissions.
Why Japanese Documents Need Specialized Translators
Our Japanese translators are experts in Japan's koseki (戸籍) family register system, which serves as the foundation for all civil documentation in Japan. They accurately convert Imperial era dates (Shōwa, Heisei, Reiwa), handle the interplay of Kanji, Hiragana, and Katakana within legal documents, and produce romanized name spellings that match the Hepburn system used in Japanese passports.
Whether you need a 戸籍謄本 for a marriage-based immigration petition, Japanese university transcripts for U.S. graduate school admission, or a set of Japanese corporate documents translated for a cross-border M&A transaction, our Japanese team provides certified translations with script-perfect accuracy.

Why Japanese Translation Requires Expertise
Japanese presents unique linguistic challenges that machine translation and non-specialist translators consistently fail to handle correctly.
Three Writing Systems
Japanese simultaneously uses Kanji (漢字), Hiragana (ひらがな), and Katakana (カタカナ), often mixed within a single sentence. Legal documents primarily use Kanji with specific readings that differ from everyday usage.
Koseki Family Register
Japan's family register system (戸籍/koseki) is the foundation of civil documentation. Birth certificates, marriage records, and family lineage are all recorded in the koseki, which follows a unique format with no Western equivalent.
Honorific Language (Keigo)
Japanese has an elaborate system of honorific speech (敬語/keigo) with three levels. Legal and official documents use the highest register, and translators must understand these distinctions to accurately represent the document's formality.
Imperial Calendar System
Official Japanese documents use the Imperial era calendar (元号/gengō) alongside the Western calendar. Translators must accurately convert dates — "令和7年" = 2025 in the Reiwa era.
Machine vs. Professional Translation
See why Google Translate and AI tools can't replace certified human translators for legal documents. A single mistranslated term can delay your case or invalidate your filing.
“本証明書は、戸籍法に基づき、市区町村長が発行したものである。”
“This certificate was issued by the mayor of the city, ward, town, or village based on the family register law.”
“This certificate has been issued by the head of the municipal government in accordance with the Family Register Act.”

Certified & Notarized Japanese Translation for Immigration
USCIS, immigration courts, and state agencies require certified translations of all foreign-language documents. Our Japanese translations meet every federal and state requirement.
Certified Translation
Every Japanese translation includes a signed Certificate of Accuracy — a sworn statement by the translator attesting that the translation is complete and accurate. This is the minimum requirement for USCIS filings, court submissions, and academic credential evaluations (WES, ECE, NACES members).
Notarized Translation
A notarized translation adds a notary public’s verification that the translator’s signature is authentic. Some state courts, foreign consulates, and government agencies require notarization in addition to certification. We provide notarized Japanese translations with same-day availability.
Apostille Services
For Japanese documents being used internationally, an apostille certifies their authenticity under the Hague Convention. We coordinate apostille services with the Secretary of State’s office, providing a complete package: certified translation + notarization + apostille — ready for international legal use.
