Certified Translation of Japan Documents for USCIS
Translating Japanese civil documents for USCIS is unlike most countries because Japan keeps no Western-style standalone certificates — nearly every birth, marriage, divorce, and death is proven through the koseki (戸籍) family-register system maintained by municipal offices tied to a person's honseki (registered domicile). The records use Japanese imperial-era dates (Reiwa, Heisei, Shōwa), family-name-first name order, and — on older, non-computerized registers — vertically written, often handwritten entries, all of which a translator must handle correctly. Japan is a Hague Apostille country, but USCIS itself asks only for a complete certified English translation with a signed Certificate of Accuracy, not an apostille. Getting the era-date conversions and the household-wide koseki event lines right is what keeps these filings from being questioned.

GOOD TO KNOW
Issuing Authority & Authentication
Civil records in Japan are issued by the 市区町村役場 (Municipal City/Ward/Town/Village Office), which maintains the 戸籍 (Koseki) family-register system · official language(s): Japanese. Japan has been a party to the Hague Apostille Convention since 1970, and apostilles on public documents are issued by Japan's Ministry of Foreign Affairs (MOFA) — no embassy or consular legalization is required. For USCIS filings an apostille is generally not needed; USCIS reviews the Japanese document plus a complete certified English translation.
Every document above is translated by a native specialist, reviewed by a second linguist, and delivered with a signed Certificate of Accuracy that USCIS accepts under 8 CFR 103.2(b)(3) — or we fix it free and cover your resubmission fee.
FAQ
Frequently Asked Questions
Do I need an apostille on my Japanese documents for USCIS?
Generally no. Japan issues apostilles through its Ministry of Foreign Affairs, but USCIS reviews the foreign-language document together with a complete certified English translation — an apostille is not part of what USCIS requires (though a later immigrant-visa or consular step may separately ask for one).
My koseki uses Reiwa, Heisei, or Shōwa years — is that a problem?
No, as long as the translator converts each Japanese imperial-era date to its Gregorian equivalent. We convert every era date accurately and can show the original era year alongside it so nothing is lost.
Should I get the full koseki tōhon or the shorter koseki shōhon?
For family-based USCIS petitions the full family-register extract (koseki tōhon / zenbu-jikō shōmeisho) is usually safer, because it shows the entire household and every recorded event; the abbreviated shōhon may omit a relationship an officer wants to verify.
My Japanese diploma is already in English — do I still need a translation?
If your university issued an official English-language diploma or transcript, USCIS generally accepts it as-is. Only the Japanese-language version requires a certified translation; we can advise once we see what you have.
My police certificate is in a sealed envelope and already in English — what do I do?
Leave the envelope sealed for the receiving authority. The 犯罪経歴証明書 is issued in English, so it usually needs no translation; if you received a Japanese-only version, we can translate a copy without you breaking the seal.
