Documents Japan issues, in the format American officers expect
The hardest part of a Japanese document is rarely the language — it is the system behind it. Japan does not issue birth certificates the way the U.S. does; it keeps a koseki, a family register that proves birth, marriage, adoption and lineage in a single record, supported by the juminhyo residence certificate. EKO 4 National Translation Service turns these into certified English translations that U.S. authorities read without a second question: word for word, every seal and annotation, a signed accuracy affidavit on official letterhead, our wet stamp — and a 100% acceptance guarantee behind it all.
Two conversions decide whether a Japanese translation is accepted. Era dates — Reiwa, Heisei, Shōwa — must land on the exact Gregorian year, and kanji names can carry several readings, so we verify the romanization against your passport instead of guessing. The layout mirrors the register itself, letting an officer match entry to entry at a glance. Serving all 50 states since 1991, with express 24-hour delivery available.

Why EKO 4 for this language
The koseki, entry by entry
Tohon and shohon extracts are Japan’s master civil record. Each entry, annotation and registrar stamp is translated in a layout USCIS and consulates recognize immediately — family relationships readable at a glance.
Imperial dates, exact years
Shōwa 52 is 1977 — and your translation has to say so. Every era date is converted to its precise Gregorian equivalent alongside the original, so no reviewer ever does calendar arithmetic on your case.
Romanization you confirm
One kanji, several possible readings. We match your name to your passport and earlier filings — and you sign off on the spelling before we certify, keeping your entire file consistent.
Need it official? One order covers the whole chain
Certified translation, notarization and apostille — handled in-house, in a single online order, wherever in the country you are.
Certified translation
Word-for-word translation with a signed accuracy affidavit, official letterhead and wet stamp — accepted by USCIS, courts and authorities nationwide.
Notarization
A licensed notary notarizes your translation 100% online — no office visit, ready as fast as the next business day.
Apostille
We obtain the apostille from the correct competent authority — the issuing state’s Secretary of State, or the U.S. Department of State for federal documents — end to end.

Japanese translation — questions & answers
EKO 4 National Translation Service delivers professional, human translation
in up to 72 languages — coast to coast
Every certified translation at EKO 4 is produced by a vetted human linguist — educated, widely experienced and genuinely at home in both of their languages. That is what allows us to stand behind a 100% accuracy guarantee across more than three decades of work.
From our first project in 1991 to the 50,000+ clients we serve today, the formula has never changed: careful translators, disciplined proofreading and honest service. It is why a first order so often becomes a working relationship that lasts for years.
EUROPEAN
ASIAN, AFRICAN, MIDDLE EASTERN
No translation leaves our hands on a single pass. Before any linguist joins EKO 4 they are recruited, vetted, interviewed and examined; once on a project, their work moves through editors and project managers who proofread it again before it ever reaches you. That layered process is the machinery behind our 100% accuracy guarantee.
Most of our 500+ translators and editors have spent years inside international, multi-cultural projects, so the finished document does not merely say the right words — it speaks to the audience, authority or market it was written for.
Professionalism, precision and fair pricing, backed by a 100% quality guarantee. Wherever in the country you are, EKO 4 speaks your language — explore all of them on our languages page.
