Getting married in Japan as a foreigner

No — and this is the most important thing to understand. Marriage and the spouse visa are two separate steps. Becoming legally married grants you no residence status at all; it only makes you eligible to then apply for the "Spouse or Child of Japanese National" visa. You cannot marry while visiting on a tourist stay and simply remain — you still have to go through the COE and visa process (or a change of status, which from a tourist stay is discretionary and often refused).

Neither is inherently faster for the visa — what the immigration application needs is the marriage recorded on the Japanese koseki, and both routes get you there. Choose by circumstance: if you are both in Japan, marrying at a city office is usually simplest; if the foreign spouse is abroad, marrying there and reporting it to Japan can be easier than travelling. Marrying abroad adds one step (reporting the marriage into the koseki); marrying in Japan front-loads the capacity-to-marry document.

Yes, in practice. The COE checklist asks for the Japanese spouse's koseki showing the marriage, so the registration has to be complete and recorded first. After you file the 婚姻届, the koseki typically updates within one to two weeks; if you need to move quickly, a 婚姻届受理証明書 (Certificate of Acceptance of Marriage Registration) proves the marriage exists from day one, but plan for the koseki to be the document immigration actually wants.

It depends on your country, and it is separate from the visa. Japan considers you married once the 婚姻届 is accepted, and that is what the COE relies on. Some countries automatically recognise a marriage validly performed in Japan; others want you to report it to your own authorities. Reporting it home is good practice (it keeps your records consistent and matters for things like passports and future paperwork), but it is generally not what holds up the Japanese spouse visa.

Usually one to two weeks, though it varies by municipality and is slower if the office sends the paperwork to the registered domicile (本籍) elsewhere. The marriage is legally effective from the date the 婚姻届 is accepted, not the date it appears on the koseki — so the wait is administrative, not a delay to your married status. Order the koseki tohon once it shows the marriage, and check it is issued within the COE checklist's freshness window.

It is a document proving you are legally free to marry under your own country's law — single, of age, no legal impediment. Japanese city offices require it from the foreign partner before registering an international marriage. How you obtain it depends entirely on your nationality: some countries' embassies in Japan issue it directly; others (including the US, Canada, and Australia) do not issue a certificate, so a sworn affidavit or statutory declaration stands in its place. Check your country guide for the exact route.

Significantly, and most online guides have not caught up. US Embassies/Consulates stopped notarizing the Affidavit of Competency to Marry on September 1, 2025; use the embassy's downloadable sworn-statement PDF or US remote online notarization. The affidavit itself is still what a Japanese city office expects from a US citizen; what changed is how you execute it. Confirm the current steps on the US Embassy Japan marriage page (and our US country guide) rather than following an older walkthrough that assumes consular notarisation.

This is a known situation, and the answer is an honest explanatory note. Where a country genuinely does not issue the document immigration expects, you submit a written statement explaining that — ideally with whatever official confirmation exists — alongside the documents you can provide (the koseki, the certificate of acceptance, your capacity document). The documents page covers these substitutes; the key is to address the gap openly rather than leave a required item simply missing.

For a standard spouse-visa case, no — the ISA does not require an apostille or notarisation on the marriage certificate. What it does need is a Japanese translation, which you or your spouse may prepare (put the translator's name and the date on it). Beware guides that bolt on apostille and certified-translation requirements that Japan does not actually impose for this application.

For the marriage to be legally complete, acceptance of the 婚姻届 is enough — you are married from that moment, and the 婚姻届受理証明書 proves it. For the COE, though, immigration generally wants the koseki tohon showing the marriage, so a bare receipt is a stopgap, not the finish line. Use the certificate of acceptance if you must act before the koseki updates, but expect to provide the koseki.

Some municipal offices scrutinise international marriages more than domestic ones, occasionally with questions about how you met and your life together. It can feel like the visa interview arriving early, but it is a registration check, not the immigration examination. Answer plainly and consistently; the registration and the later visa review are separate processes run by different authorities, and clearing one does not decide the other.

Your capacity-to-marry document (or affidavit) has to reflect that any previous marriage is fully dissolved, so you may need divorce documentation to obtain it. Note also that some legal systems impose a remarriage waiting period; the capacity document is where that is confirmed. Separately, when you later file the COE, immigration may ask for the prior marriage and divorce records, so keep them to hand.

You do not have to, and rushing it can cause more trouble than it solves. Taking your spouse's surname is optional, and the visa does not require a matching passport name. What matters is consistency: if your passport shows your maiden name and other documents show a married name, note the connection so the file is coherent. Changing the passport is a separate, home-country process you can do on your own timeline — just keep the names explainable across your documents.

No. A recent marriage is normal and approved routinely — the spouse visa exists to let newly married couples live together. What a short marriage does is shift weight onto your relationship evidence, since there is less shared history to point to: a thorough questionnaire, communication records, and photos over the course of the relationship carry the case. Genuineness, not duration, is what is examined; see the rejection page for how that judgement actually works.
