You and your spouse signed a one-page form, took it to a city office counter, and a clerk accepted it. In Japan you are now divorced. Whether your own country agrees is a separate question, and the answer is not always yes.
What actually happened at the counter
Japan’s kyogi rikon — divorce by agreement — is completed by filing a notification at a municipal office. Two witnesses sign the form. No judge sees it. No hearing takes place. There is no decree, because the system does not produce one.
This is how most divorces in Japan are done, and for people living here it is the quickest route. It is also unusual by international standards. Most legal systems treat divorce as something a court grants, and their recognition rules were written with a foreign judgment in mind. A Japanese divorce by agreement is not a judgment.
That mismatch is the whole of this article.
The provisions are Article 763 of the Civil Code, which allows spouses to divorce by agreement, and Article 764, which applies the marriage-notification rule in Article 739 to divorce. Article 739(2) is why two adult witnesses have to sign the form. Where there are minor children, Article 765(1) bars the office from accepting the notification unless custody has been settled — or an application to have it decided is already before the family court.
First: why Japanese law applied to you at all
Before the recognition question, there is a choice-of-law question, and Japan answers it in a way that catches many foreign spouses by surprise.
Article 27 of the Act on General Rules for Application of Laws contains a proviso: where one spouse is a Japanese national who habitually resides in Japan, the divorce is governed by Japanese law.
So if your spouse is Japanese and lives in Japan, Japanese law governs — including the option of divorcing by agreement — regardless of your own nationality. You do not have to consent to Japanese law applying; it applies. What you do have to consent to is the divorce itself, because a divorce by agreement requires the signatures of both spouses.
A fuller treatment of which law applies is on our divorce for international couples page.
Being divorced in Japan is not the same as being divorced at home
Whether your home country recognises the divorce is decided by your home country’s law, not by Japanese law and not by us.
Some systems recognise a foreign divorce however it was obtained, provided certain conditions are met. Others recognise only divorces granted by a court or a comparable authority. Some require registration with their own authorities before the divorce has any effect there. In federal systems the rules can differ between states or provinces.
We are not able to tell you which category your country falls into. That is a question of that country’s law, and answering it requires someone qualified there. What we can do is tell you what Japan will and will not give you, and make sure you leave with the documents that any of those systems will ask for.
What goes wrong when the two do not line up
If Japan treats you as divorced and your home country does not, you are married in one place and single in another. It surfaces later, and usually at a bad moment:
- when you remarry — a second marriage may be void where the first is still recognised;
- on death and inheritance — a former spouse may still count as a spouse there;
- when registering the status of a child born after the divorce;
- in pension, tax and social security treatment.
None of this is theoretical. It is the ordinary consequence of two systems disagreeing about your marital status.
If your spouse is not in the same country as you
A divorce by agreement needs both signatures on the form. That is straightforward while you are both in Japan and much less so afterwards.
- If one of you has already left, the form is usually posted for signature and returned. It still has to be filed at a Japanese municipal office.
- If the other spouse will not sign, or cannot be reached, the agreement route is closed. What remains is family court mediation, and then adjudication or litigation.
- Where one party is abroad, service of court documents can take months, and in some countries it goes through a treaty procedure.
There is also a protection running the other way. A divorce notification is filed over a counter, and identity is checked there, but the system does not make it impossible for one spouse to file alone. If you are concerned about that, you can lodge a request for non-acceptance with the municipal office. While it stands, a notification will not be accepted until you appear in person.
The document problem, and why it matters more for you than for your spouse
Here is a practical point that English-language material almost never mentions.
Japan records personal status in the family register (koseki). A koseki is created for Japanese nationals. You, as a foreign national, are not in it. Your Japanese spouse’s register will show the divorce; you have no register of your own to show anyone.
What Japan gives you instead is documentary evidence of the filing:
- the acceptance certificate for the divorce notification (rikon todoke juri shomeisho), issued by the municipal office where the form was filed;
- a certificate of recorded matters from the notification itself, which sets out the contents of the form;
- your former spouse’s family register extract showing the divorce entry.
For use abroad these normally need a translation, and certification by Japan’s Ministry of Foreign Affairs. Which form of certification you need — an apostille or consular legalisation — depends on the destination country.
Collect these before you leave Japan. Obtaining them later, from outside the country, is possible but slower, and the municipal office that holds the record is the one where the form was filed, which may not be where you last lived.
If your country needs a court document
Where a foreign system will only recognise a divorce granted by a court, the Japanese route to something court-issued is family court mediation (chotei), or an adjudication or judgment. Each produces a document created by the court — a mediation record, an adjudication, or a judgment — rather than a municipal filing.
⚠️ We cannot tell you that a Japanese mediation record will be recognised where a Japanese divorce notification would not. That is again the other country’s question. What we can say is that if the requirement there is “a document issued by a court”, the mediation route produces one and the notification route does not.
The three routes, and what each leaves you holding
| Route | Court involved | Document produced |
|---|---|---|
| Divorce by agreement (kyogi rikon) | No | Acceptance certificate for the notification; entry in the family register |
| Mediated divorce (chotei) | Yes | Mediation record; entry in the family register |
| Adjudication or judgment | Yes | Adjudication or judgment; entry in the family register |
Only the lower two produce something a court issued.
This is worth settling before you file. Going through mediation first is an ordinary path. Unwinding a completed divorce by agreement in order to obtain a court document afterwards is not.
What we would tell you in a first meeting
- Which law governs your divorce, and why.
- What each route in Japan produces, on paper.
- Which documents to obtain, from which office, and in what order.
- Which questions you need to put to your own country’s authorities or to a lawyer there — and which of them we cannot answer for you.
We would rather draw that line clearly at the start than let you discover it later.
