Japan is a party to the Hague Apostille Convention (in force since 27 July 1970). A U.S. public document bound for Japan needs a single apostille from the competent authority of the state that issued or notarized it, or from the U.S. Department of State for federal documents. No embassy or consular legalization is required, and Japan's authorities cannot demand one.
Ratified 1970-05-28; in force 1970-07-27 (HCCH).
The route, step by step
- Identify the issuing office
State or local signature → that state’s competent authority. Federal signature → U.S. Department of State. How to tell.
- Prepare the right version
Certified copies for vital and court records; complete notarization for private documents. Preparation checklist.
- Request the apostille
Name Japan as the destination on the request form so the office issues an apostille (not an authentication certificate).
- Translate if required
Confirm with the receiving office in Japan whether a translation is needed and by whom it must be made.
Using U.S. documents in Japan
Japan accepts U.S. apostilles; Japanese apostilles come from the Ministry of Foreign Affairs. Translations into Japanese are generally required for official use and may be prepared by any competent translator — Japan has no sworn-translator system — with the translator’s name and date on the translation. Typical documents: marriage (U.S. citizens swear a konin yoken gubi shomeisho affidavit of competency to marry at the U.S. Embassy or consulates, which municipal offices accept without apostille; apostilles are needed on U.S. birth certificates and divorce decrees when requested), registration of foreign births and marriages, visas and residence (apostilled FBI check for some categories; apostilled degrees for the Highly Skilled Professional points system are sometimes requested), POAs for property and inheritance (Japanese shiho shoshi and notaries require apostilled, translated POAs), and corporate documents for KK/GK registration. Japan launched an online apostille register in 2026 and accepts e-apostilles.

Frequently asked questions
Do I need an apostille or legalization for Japan?
An apostille. Japan is a Hague Convention member, so no embassy legalization is needed.
Who issues the apostille for Japan?
The U.S. state that issued or notarized the document, or the U.S. Department of State for federal documents — never a U.S. embassy, and never Japan’s embassy.
Does Japan require a translation?
Requirements vary by the receiving authority in Japan; translate after the apostille with the translator type they specify.
