Japanese is one of the most complex languages to translate accurately. With three writing systems — kanji, hiragana, and katakana — plus specialized legal and bureaucratic terminology, Japanese document translation requires deep linguistic expertise. At Corpus Localization, our Japanese translators are native speakers with years of experience translating official Japanese documents for U.S. immigration, academic, and legal purposes.
We translate both Japanese to English and English to Japanese, with certified translations accepted by USCIS, U.S. courts, universities, credential evaluation agencies like WES and ECE, and government agencies nationwide.
Japanese official documents follow strict formatting conventions established by municipal and prefectural offices. Whether it’s a family register (koseki tohon), a residence certificate (juminhyo), or a university diploma, our translators understand the structure and terminology of Japanese government-issued documents and produce translations that meet U.S. standards.

Japan’s civil registration system is unique. Unlike most countries that issue individual birth certificates, Japan uses the koseki (family register) system — a comprehensive record of a family’s births, marriages, divorces, deaths, and adoptions maintained by the municipal government. When USCIS or a U.S. court requires a “birth certificate,” Japanese nationals typically need their koseki tohon translated.
Our translators are thoroughly familiar with the koseki system, including:
We also handle documents from Japan’s era-based calendar system (Showa, Heisei, Reiwa) and convert dates accurately to the Gregorian calendar used in the United States.

Koseki tohon for USCIS — The family register is required for nearly every Japanese immigration case. We translate the complete register including all family members, annotations, and administrative notes. Typically 1-3 pages, starting at $19.99 per page.
Japanese university diplomas for credential evaluation — WES, ECE, and other evaluation agencies require certified English translations of Japanese diplomas and transcripts. We translate the full document including institutional seals and grading notations.
