Getting married in Japan as a foreigner is absolutely possible — but the paperwork can feel intimidating if you don’t know the steps. Whether you’re marrying a Japanese national or another foreigner, this 2026 guide walks you through exactly which documents you need, where to submit them, and what to do afterward (including the all-important spouse visa). Follow it step by step and you’ll avoid the most common delays.

Can Foreigners Legally Get Married in Japan?

Yes. Japan recognizes marriages between a foreigner and a Japanese citizen, as well as between two foreign nationals, as long as both people meet the legal requirements of their home countries and complete Japan’s registration process. Marriage in Japan is a civil (paperwork) procedure — there is no legal requirement for a ceremony. The marriage becomes official the moment your marriage registration (konin todoke) is accepted at the municipal office.

The Key Document: Certificate of Legal Capacity to Marry

The single most important document for a foreigner is the Certificate of Legal Capacity to Marry (婚姻要件具備証明書, konin yoken gubi shomeisho), sometimes called an “Affidavit of Competency to Marry.” It proves that you are legally free to marry under your own country’s laws.

You obtain it from your country’s embassy or consulate in Japan. Requirements vary by country — some embassies issue it on the spot, others require an appointment or notarization. If the certificate is not in Japanese, you’ll need a Japanese translation (you can usually translate it yourself and sign it).

Documents You’ll Typically Need

Requirements differ slightly by municipality and by your nationality, so it is always worth checking your local ward office’s website in advance.

Step-by-Step: How to Register Your Marriage

Step 1. Get your Certificate of Legal Capacity to Marry

Contact your embassy in Japan and follow their procedure. Build in extra time — this is the step most likely to cause delays.

Step 2. Prepare the konin todoke form

Pick up the marriage registration form at any municipal office. Fill it in fully. You’ll usually need two witnesses aged 18 or over to sign it (friends, family, or your partner’s parents).

Step 3. Submit everything to the municipal office

Take all documents to the city or ward office of either partner’s residence. Once accepted, you are legally married from that day. You can submit at the after-hours window on weekends, though document checks happen the next business day.

Step 4. Request proof of marriage

Ask for a Certificate of Acceptance of Marriage (受理証明書) or, later, an updated family register. You’ll need proof of marriage for your visa application and your embassy.

Step 5. Report to your embassy (if required)

Many countries require you to register the marriage at home too. Check with your embassy so your marriage is recognized in your own country.

After Marriage: The Spouse Visa

Marrying a Japanese citizen does not automatically give you the right to live in Japan. To switch to a Spouse or Child of Japanese National residence status, you apply separately at your regional Immigration Services Agency office. Typical documents include your marriage certificate, your spouse’s family register, proof of income, and an application form. Processing usually takes a few weeks to a couple of months.

If you already hold another valid status of residence (work, student, etc.), you are not required to switch — but the spouse visa often gives more freedom to work.

Marriage Between Two Foreigners in Japan

Two foreign nationals can also marry in Japan. Each partner submits their own Certificate of Legal Capacity to Marry from their respective embassy, plus passports and residence cards. Some embassies handle the entire marriage for their citizens directly — check whether your country prefers embassy registration, Japanese municipal registration, or both.

Final Thoughts

Marrying in Japan comes down to two things: getting your embassy’s Certificate of Legal Capacity to Marry, and submitting a complete konin todoke at your local office. Start the embassy paperwork early, keep translations ready, and remember the spouse visa is a separate step. With everything prepared, the registration itself takes just one visit — and then you’re officially married in Japan. Congratulations in advance!
