Supporting Cross‑Border Relationships with Reliable Legal Procedures
◆Marriage Procedures for Foreigners in Japan
If you are thinking about marrying a Japanese partner, please remember that you may need to follow the marriage rules of both Japan and your own country.
In Japan, the marriage process is usually simple when you follow the required steps. However, your home country may have different legal conditions for marriage.
For example, in Japan, people can get married from the age of 18. But if your country requires both people to be 20 or older, your country may say that your marriage is “not valid yet,” even if it is fully valid in Japan.
This means a marriage can be accepted in Japan but not accepted in your home country. To avoid any problems later, please check the marriage rules in both countries before you complete the process.
◆Which Country’s System Will You Use to Marry?
The procedures for getting married can vary depending on whether you choose to marry in Japan or in your country.
For example, if you decide to marry in Japan, the standard process is to submit a marriage registration (kon’in todoke) together at your local city or ward office. This is the official procedure required under Japanese law for a marriage to be legally recognized.
On the other hand, if you plan to marry in your country, it’s important to first check the legal requirements there.
In Japan, you can consult the embassy or consulate of your country. If you’re already abroad, it’s best to contact the local government office that handles marriage procedures.
While there is a lot of information available online, laws and regulations can change.
So it’s safest to treat online sources as general references only, and always confirm the latest requirements directly with official authorities.
◆Marriage Procedures
There are two main ways to complete the marriage registration process.
1) Registering Your Marriage First in Japan, Then Reporting It Abroad
In Japan, once a couple decides to get married, they can legally register their marriage by submitting a marriage notification (kon’in todoke) to their local city or ward office.
Even if one partner is a foreign national, the procedure in Japan generally follows the same steps as for two Japanese nationals.
However, in international marriages, there’s one more important step: informing your partner’s country that the marriage has taken place. This process is known as a “reporting notification” (hōkokuteki todoke)
Depending on the laws of your partner’s country, this notification is usually submitted through their embassy or consulate.
By completing this step, your marriage can be officially recognized in your partner’s country as well—giving you peace of mind as you begin your life together.
2) Registering Your Marriage First in Your Country, Then Reporting It in Japan
In international marriages, the procedures required in your country may differ from those in Japan. For example, some countries involve religious ceremonies as part of the legal process, or recognize various forms of marriage beyond civil registration.
That’s why it’s essential to research in advance which methods are legally valid in your country. Consulting with the local government office or the embassy is a reliable way to ensure that your marriage will be properly recognized.
Once your marriage is officially registered abroad, you’ll also need to report it to the Japanese authorities. There are two main ways to do this:
– You can notify your partner’s embassy or consulate in Japan, or
– You can submit a reporting notification to your local city or ward office in Japan.
By respecting each other’s cultures and legal systems, you can take meaningful steps forward together.
◆Understanding the Certificate of Legal Capacity to Marry
A Certificate of Legal Capacity to Marry—sometimes referred to as a “certificate of no impediment” or “single status certificate”—is an official document that proves the individual is legally free to marry.
It confirms that the person is unmarried and meets the legal requirements for marriage under the laws of your country.
This certificate is often required when going through international marriage procedures in Japan. However, not all countries issue this document.
In such cases, an alternative form of documentation may be provided by the relevant authorities in your country.
◆When You Are Required to Obtain a Certificate of Legal Capacity to Marry
To register a marriage in Japan with a foreign national, a Certificate of Legal Capacity to Marry is required.
This document, issued by the government of your country, certifies that the individual is legally free to marry under your national laws.
The issuing authority varies depending on the country. In some cases, the certificate can be obtained through the embassy or consulate in Japan. In other cases, it must be requested directly from the appropriate government office in your country.
◆When Japanese Nationals Are Required to Obtain a Certificate of Legal Capacity to Marry
When a Japanese national plans to get married abroad, they are required to obtain a document called a Certificate of Legal Capacity to Marry. This certificate serves as official proof that the individual is legally eligible to marry under Japanese law. The certificate can be obtained from one of the following authorities:
A Legal Affairs Bureau (Hōmukyoku) in Japan
The municipal office where the person is registered as a resident
A Japanese embassy or consulate, if the person is currently living overseas
It’s important to note that the appropriate issuing authority may vary depending on the country where the marriage will take place.
Some countries, for example, may only accept certificates issued specifically by a Legal Affairs Bureau. In this sense, the certificate is more than just a formality—it’s an essential document that allows Japanese nationals to prepare for marriage abroad in a way that respects the legal requirements of the other country.
It reflects a thoughtful and careful approach to honoring both legal systems.
◆Required Documents for Marriage Registration in Japan
The following documents are typically required.
Depending on your country or your specific situation, additional documents may also be necessary.
1) Required Documents for Japanese Citizens
- Marriage Registration (submitted to the municipal office)
- Family Register (Koseki Tohon) Not required if the marriage is being registered at the municipal office of your permanent domicile (honseki-chi)
- Identification Document A government-issued photo ID such as a driver’s license or passport
- Personal Seal (Inkan or Hanko)
2) Required Documents for Non-Japanese Citizens
- Certificate of Legal Capacity to Marry
- Translation of the Certificate of Legal Capacity to Marry
- Passport
◆What Is an Apostille?
In international marriage procedures, Japanese documents may need to be submitted to government offices in your country.
At that point, the foreign authority may ask, “Is this document really authentic?” That’s where the apostille comes in.
An apostille is a type of official certification issued by Japan’s Ministry of Foreign Affairs, confirming that the document is genuine and legally valid. It functions like a stamp of authenticity.
However, this system only applies to countries that are members of the Hague Convention (Apostille Convention). If the country is not a member, a different process—such as consular legalization—will be required instead.
◆Acceptance of the Marriage Registration
If all required documents for marriage are properly prepared, the marriage registration is usually accepted on the spot at the municipal office.
However, depending on the content of the documents or the legal circumstances of the foreign partner’s country, the office may not be able to make an immediate decision.
In such cases, the application may be temporarily put on hold while the municipal office initiates a procedure called jurisdictional inquiry (juri shōkai), in which they consult the Legal Affairs Bureau to confirm whether the marriage can be legally accepted.
◆Examples of Cases Requiring a Jurisdictional Inquiry
- When Required Documents Are Incomplete: Submitting Alternative Documents for Marriage Registration
- When Documents Are Present but Incomplete or Poorly Translated
- When the Foreign Partner Has Visa or Residency Issues
- When a sham marriage may be suspected
- When the Foreign Partner Is from a Country with Limited Precedent in Japanese Marriage Procedures
- When the Municipal Officer Is Unfamiliar with the Procedure and Proceeds Cautiously
◆Reporting the Marriage to Your Government
Even after completing the marriage registration process in Japan, you may still need to notify your country that the marriage has taken place.
This is known as a "reporting notification" or "post-marriage notification" to your government.
In most cases, this procedure can be carried out at the embassy or consulate of your country in Japan. However, requirements vary significantly by country.
For example
Some countries do not accept notifications within Japan, and require you to submit the documents directly to government offices in your country.
Other countries do not require any notification at all. Because of these differences, it is essential to contact the embassy or consulate of your country in Japan to confirm what procedures and documents are necessary. While many embassies provide information on their websites, it’s a good idea to call or email them directly if anything is unclear.
◆When Completing the Marriage Procedure in Your Country
In Japan, a marriage becomes legally valid when the marriage registration (kon'in todoke) is submitted to and accepted by the municipal office.
However, in some other countries, the legal recognition of marriage may depend on the wedding ceremony itself or on religious rites. In other words, the way a marriage is legally established can differ significantly depending on the country’s legal system.
That’s why it’s essential to thoroughly research the marriage laws and procedures of your country before proceeding.
Examples of Marriage Procedures in Other Countries
- When a Marriage Is Legally Recognized Through a Wedding Ceremony Alone
- When a Religious Ceremony at a Church Is Legally Recognized as Marriage
- When Both a Wedding Ceremony and Civil Registration Are Required for a Valid Marriage
◆The First Step in Registering Your Marriage Overseas
- Contact the embassy or consulate of your country in Japan
- If You Are in the Country, Consult the Local Government Office Directly
◆What Happens to Your Family Registry After Marriage
When a Japanese national completes the marriage registration process, they are removed from their parents’ family register and a new family register (koseki) is created.
The head of this new register must be a Japanese national—foreign nationals cannot become the head of a koseki.
The Japanese spouse retains their original surname unless a separate name change procedure is undertaken. The foreign spouse’s full name and nationality are recorded in the “personal details” section (mibun jikō) of the newly created family register.
This notation serves as official proof that the couple is legally married under Japanese law. This system reflects the fact that the koseki is a public registry exclusively for Japanese nationals.
By law, individuals with foreign nationality cannot be entered into a koseki as family members, which is why their information appears only as a reference in the personal details section.
◆Using the Foreign Partner’s Surname After Marriage
Even if a Japanese national marries a foreign partner, their surname on the family register (koseki) does not automatically change.
In other words, after marriage, the Japanese spouse retains their original (maiden) name unless they take further steps. If the Japanese spouse wishes to adopt the foreign partner’s surname, they must submit a Notification of Surname Change (shi no henkō todoke) to the municipal office.
However, timing is crucial: If submitted within six months of the marriage registration, the process is relatively simple—just file the notification based on marriage to a foreign national.
If more than six months have passed, the Japanese spouse must first obtain permission from the Family Court, which makes the procedure more complex. It’s important to be aware of this timeline to avoid unnecessary complications.
◆Next Step: Applying for the 'Spouse of Japanese National' Visa After Marriage Registration
To apply for the “Spouse of Japanese National” residence status, you must submit official documents that prove the marriage—such as a family register (koseki tōhon) showing the marriage with the foreign spouse, or a marriage certificate. This means that the marriage registration process must be fully completed before you can begin the visa application.

If you marry a Japanese national and wish to live together in Japan, the first step is to apply for the residence status of “Spouse or Child of Japanese National.”
To do this, you must submit an Application for Certificate of Eligibility (zairyū shikaku nintei shōmei-sho kōfu shinsei).
However, even if your marriage is legally valid, the documents alone may not fully convey your situation. Immigration authorities often require surprisingly detailed information, and documents that seem sufficient at first glance may turn out to be incomplete.
That’s where a Gyoseishoshi (Certified Administrative Procedures Legal Specialist) can be a valuable ally. 💡 A gyoseishoshi will carefully review your application and clearly advise you on what documents are sufficient, what may be missing, and what additional explanations or evidence should be provided to strengthen your case.

◆Changing Your Current Visa to ‘Spouse of Japanese National’ After Marriage Registration
If you currently reside in Japan under a work-related visa such as “Engineer/Specialist in Humanities/International Services” and have completed the marriage registration with a Japanese national, it is strongly recommended that you apply to change your residence status to “Spouse or Child of Japanese National.”
Work-related residence statuses like “Engineer/Specialist in Humanities/International Services” are tied to specific job categories. If you lose your job due to resignation or the end of a contract, you may also lose the basis for your visa, making it difficult to continue living in Japan legally.
In contrast, the “Spouse of Japanese National” status is based on your marital relationship and allows for more stable residency.
It also comes with no restrictions on employment—you are free to work in any field, from part-time jobs to full-time positions

Once you obtain the “Spouse of Japanese National” residence status, you are no longer subject to employment restrictions.
This means you are free to work in any field, from part-time jobs to full-time employment, without needing additional permits.
However, because this status offers such flexibility, immigration authorities may scrutinize applications more closely to prevent misuse—particularly in cases where marriage is suspected to be a sham for work purposes.
Even if your marriage is genuine, submitting insufficient or unclear documents may lead to a denial.
To avoid such outcomes, it is highly recommended to seek support from a Gyoseishoshi (Certified Administrative Procedures Legal Specialist). They can help you prepare the necessary documents properly and advise you on how to present your case clearly and convincingly to immigration officials.
