Word Count Target: 6,000+ words

1. Introduction {#introduction}

Getting married in Japan as a foreigner is both an exciting milestone and a surprisingly detailed administrative process. Japan's civil registration system — known as the koseki (戸籍) system — is one of the oldest family registry systems in the world, and marrying into or within it as a foreigner requires understanding several layers of bureaucracy: your home country's requirements, Japan's municipal procedures, immigration rules, and often multiple rounds of document translation and authentication.

This complete guide to marriage registration in Japan as a foreigner walks you through every step, from deciding which documents you need based on your nationality to what happens to your visa after you tie the knot. Whether you are a foreigner marrying a Japanese national, or two foreign nationals marrying each other while living in Japan, this guide covers your situation.

By the end of this article, you will know:

The exact documents required for marriage registration in Japan
How to get your home country's documents authenticated for use in Japan
How to navigate the kon'in todoke (婚姻届 — marriage notification form) submission process
How marriage affects your residence status and what visa options become available
What to do if your home country does not issue a Certificate of Eligibility to Marry
How to officially register your Japanese marriage in your home country

Japan does not have a civil ceremony requirement for marriage — there are no vows, no official, no ceremony required at all. A marriage in Japan is legally completed entirely through paperwork submitted to your local municipal office. This is great news for busy international couples: you can complete your legal marriage quickly and affordably, then celebrate however you like afterward.

2. Understanding the Legal Framework {#legal-framework}

Before diving into procedures, it helps to understand the legal principles that govern international marriages in Japan.

The Koseki System

Japan's family registration system, the koseki (戸籍), records births, deaths, marriages, and divorces for Japanese citizens. When a Japanese national marries a foreigner, a record is added to the Japanese spouse's koseki. Foreign nationals are not given their own koseki entry — instead, they are listed as a "spouse entered in registry" (nyuufu or nyu fuu, 入夫) notation referencing the foreign national.

Applicable Law: The Law on General Rules for Application of Laws (法の適用に関する通則法)

Under Japanese private international law, the legal requirements for marriage are governed by the national law of each party. This means:

A Japanese national marrying a foreigner must meet Japan's marriage requirements.
The foreigner must meet their own home country's requirements for legal marriage.
Japan respects both sets of requirements, which is why foreigners must submit documentation proving they are legally eligible to marry under their own national law.

Age Requirements

Under Japan's Civil Code (as amended in 2022, effective April 1, 2022), the minimum legal age to marry for both men and women is 18 years old. Previously, women could marry at 16 with parental consent, but this has been equalized. Parental consent is no longer required once a person turns 18.

Your home country may have different rules, but for your marriage to be registered in Japan, both parties must be at least 18 years old.

Bigamy Prohibition

Japan strictly prohibits polygamy. A person who is currently legally married — whether in Japan or abroad — cannot remarry in Japan until that marriage is legally dissolved. You will need to provide documentation proving you are single or that any previous marriages have been legally terminated.

Waiting Period After Divorce (for Women)

Japanese law has historically required women who have been previously married to wait 100 days after a divorce before remarrying. However, as of April 1, 2024, this restriction has been abolished under revisions to the Civil Code. Women no longer face a waiting period before remarrying in Japan.

3. Who Can Marry in Japan? {#who-can-marry}

Any foreigner residing in Japan — regardless of visa type — can legally marry in Japan, provided:

Both parties are at least 18 years old.
Neither party is currently married to someone else.
The parties are not closely related by blood (prohibited degrees of consanguinity).
The marriage is legal under the laws of the foreigner's home country.

There is no minimum residency requirement for foreigners who wish to marry in Japan. Even tourists on short-stay visas can, in theory, register a marriage in Japan, though this creates significant practical complications.

You do not need to be a permanent resident, a long-term resident, or hold any particular visa status to marry in Japan. However, your immigration status and your home country's rules will determine what documents you need and how easily you can complete the process.

4. Step-by-Step Marriage Registration Process {#registration-process}

The marriage registration process in Japan involves multiple stages. Here is a detailed walkthrough of each step.

Step 1: Gather Required Documents {#step1}

The exact documents required will vary by your nationality, but the core requirements are:

For the foreign national:
- A valid passport
- A Certificate of Eligibility to Marry (証明書) from your home country (often called an Affidavit of Single Status, Certificate of No Impediment, or similar — varies by country)
- A certified translation of the above certificate into Japanese (if not already in Japanese)
- Your Residence Card (zairyu card 在留カード), if you are a registered resident in Japan
- In some cases, a copy of your birth certificate, authenticated and translated

For the Japanese national spouse:
- A valid Japanese ID (driver's license, My Number card, or similar)
- Their koseki extract (koseki tohon 戸籍謄本) or koseki partial copy (koseki shohon 戸籍抄本) — issued by the municipal office where the Japanese national's family is registered
- Their residence registration (juminhyo 住民票) — optional but sometimes requested

Additional documents:
- Two witnesses are required on the marriage notification form. These can be any adults (Japanese or foreign) who are at least 18 years old. Their signature and seal (or signature alone, for foreigners) are needed.
- The completed Kon'in Todoke (婚姻届) — the official marriage notification form

Step 2: Obtain a Certificate of Eligibility to Marry {#step2}

This is often the most complex and time-consuming step for foreign nationals. Your home country must issue a document proving you are legally eligible to marry. This document goes by different names in different countries:

Country	Document Name
United States	Affidavit of Single Status (notarized)
United Kingdom	Certificate of No Impediment (CNI)
Australia	Certificate of No Impediment
Canada	Affidavit of Single Status
China	未婚证明 (Certificate of Single Status)
South Korea	혼인관계증명서 (Family Relations Certificate)
Philippines	Certificate of Legal Capacity to Contract Marriage
France	Certificate of No Impediment (Certificat de coutume)
Germany	Certificate of Capacity to Marry (Ehefähigkeitszeugnis)

Some countries issue this certificate through their embassy or consulate in Japan, which is the most convenient option. Others require you to apply to a registry office or government agency in your home country. Check with your country's embassy in Japan as your first step.

Important: Some countries — notably the United States — do not have a central authority that can certify a citizen's single status. In such cases, the individual must prepare a notarized affidavit signed before a notary public or before the consular officer at the U.S. Embassy or U.S. Consulate in Japan. The U.S. Embassy in Tokyo does provide this service.

Step 3: Have Documents Translated and Notarized {#step3}

All foreign-language documents submitted to a Japanese municipal office must be accompanied by a certified Japanese translation. Japan does not have an official list of approved translators — any person (including you yourself, in theory) can prepare the translation. However, the translation must include:

The translator's full name
The translator's address
The date of translation
A statement that the translation is accurate to the best of the translator's knowledge

In practice, most municipal offices will accept translations prepared by a professional translation service. Using a certified professional translator reduces the risk of your documents being rejected.

Authentication (Apostille or Legalization)

Before documents from your home country can be submitted in Japan, they typically need to be authenticated. The method depends on your home country:

Apostille: If your home country is a signatory to the Hague Apostille Convention, you can obtain an Apostille certification on your documents, which Japan will recognize without further authentication.
Consular legalization: If your country is not an Apostille signatory (e.g., China, Saudi Arabia, certain other countries), your documents must be legalized through your country's foreign ministry and then authenticated by the Japanese embassy or consulate in your home country.

For documents issued by embassies/consulates in Japan, this authentication step is generally already completed.

Step 4: Visit the Municipal Office (City Hall) {#step4}

Marriage is registered at the shiyakusho (市役所, city hall), kuyakusho (区役所, ward office), or chosonsho (町村所, town/village hall) in Japan. You can register at:

The municipal office where either spouse has their residential address registered (juminhyo address)
The municipal office where the Japanese spouse's koseki is registered (for Japanese citizens)

You do not need to go to the office where you live. For example, if the Japanese spouse's family koseki is registered in Osaka but you currently live in Tokyo, you can submit at either Osaka's municipal office or Tokyo's municipal office.

It is highly advisable to call ahead or visit in advance to confirm exactly what documents your specific municipal office requires. Requirements can vary slightly between municipalities, and some offices have particularly strict or particular document requirements for certain nationalities.

Most city halls are open Monday through Friday, 8:30 AM to 5:15 PM. Some offices have extended hours or weekend reception for marriage and other civil registrations — check your specific office.

Step 5: Submit the Kon'in Todoke (婚姻届) {#step5}

The Kon'in Todoke is the official marriage notification form in Japan. You can obtain it from:

Any municipal office counter
The municipal office's official website (downloadable as a PDF)
Some convenience stores (printed on A3 paper)

The form requires:

Full names of both parties (for foreign nationals, written in katakana if necessary)
Dates of birth
Nationalities
Current addresses
Parents' full names
The address after marriage (and which spouse's household registration the wife will enter — for international marriages involving a Japanese national, this section is handled differently)
Signatures of two witnesses (any adults aged 18 or over)
The seal (hanko 判子) of the Japanese spouse (if applicable)

For international couples where one person is a foreign national, the foreign national does not have a koseki and therefore does not "enter" the Japanese spouse's register in the same way. The foreign national's information is simply recorded, and the Japanese spouse's koseki will note that they have married a foreign national.

The form must be submitted in person by at least one of the two spouses. The other person does not need to be present. However, both spouses must sign the form before it is submitted.

Step 6: Receive Your Marriage Certificate {#step6}

Here is something that surprises many foreigners: Japan does not automatically issue a marriage certificate when you submit the Kon'in Todoke. The registration is recorded in the koseki system, and you must separately request a proof of marriage.

After submission, you can request:

婚姻届受理証明書 (Kon'in Todoke Jurisho Meisho) — Certificate of Acceptance of Marriage Notification. This is issued on the same day and proves your marriage has been registered. Useful for immigration and other immediate purposes. Fee: approximately ¥350 per copy.
戸籍謄本 (Koseki Tohon) — Full koseki extract. This will include the marriage record but may take a few days to be updated after submission. For the Japanese spouse's family registration address, this can be requested from that municipality.
婚姻証明書 (Kon'in Shomeisho) — Marriage certificate. This can be obtained from the municipal office and is commonly used for international purposes.

Keep several certified copies of your marriage certificate. You will likely need them for immigration applications, your home country's registration, name change applications, and other official purposes.

5. Required Documents by Nationality {#documents-by-nationality}

American Citizens {#american}

Americans face a unique situation: the U.S. government does not issue a Certificate of No Impediment or official Certificate of Single Status at the federal level. Instead, Americans must prepare a sworn affidavit (Affidavit of Single Status) and have it notarized.

Recommended process:
1. Visit the U.S. Embassy in Tokyo or the nearest U.S. Consulate in Japan (Osaka, Nagoya, Sapporo, Fukuoka, Naha).
2. Bring your valid U.S. passport.
3. Sign the affidavit before a consular officer (who acts as a notary).
4. The consular officer will notarize the document.
5. Have the affidavit translated into Japanese by a professional translator.

Required documents:
- Valid U.S. passport
- Notarized Affidavit of Single Status (from U.S. Embassy/Consulate)
- Certified Japanese translation of the affidavit
- Residence Card (if residing in Japan)

Note: Some Japanese municipal offices may additionally request a birth certificate. Check in advance with your specific city hall.

Chinese Citizens {#chinese}

Chinese citizens must obtain documents from both the Chinese consulate in Japan and relevant Chinese government agencies.

Required documents:
- Valid Chinese passport
- 未婚声明书 (Declaration of Single Status) — notarized at the Chinese Embassy or Consulate in Japan
- In some cases, a 单身证明 (Certificate of Single Status) from the local Public Security Bureau or Civil Affairs Bureau in China, authenticated by the Chinese Ministry of Foreign Affairs and then by the Japanese Embassy in China (if obtained in China)
- Certified Japanese translation of all Chinese-language documents

Important note: China is not a signatory to the Hague Apostille Convention, so Chinese documents require consular legalization rather than an Apostille. The most practical approach is to obtain the notarized declaration from the Chinese Consulate in Japan.

Korean Citizens {#korean}

Korean citizens benefit from a relatively straightforward process due to close administrative ties between Japan and South Korea.

Required documents:
- Valid Korean passport
- 혼인관계증명서 (Certificate of Marriage Relations) — shows current marital status; issued by the local government office (주민센터) in South Korea or by the Korean Consulate in Japan
- 기본증명서 (Basic Certificate) — family status document
- Certified Japanese translation of Korean documents

Both the 혼인관계증명서 and 기본증명서 can be obtained online through Korea's government portal (정부24, Government24) or through the Korean Consulate General in Japan.

Vietnamese Citizens {#vietnamese}

Required documents:
- Valid Vietnamese passport
- 독신 증명서 / Xác nhận tình trạng hôn nhân (Certificate of Single Status / Marital Status Certificate) — issued by the Vietnamese Consulate in Japan or by local People's Committee in Vietnam
- Certified Japanese translation of all Vietnamese documents

Vietnam is not a signatory to the Hague Apostille Convention. Documents obtained from government offices in Vietnam must be authenticated by the Vietnamese Ministry of Foreign Affairs and then by the Japanese Embassy in Vietnam. Documents issued by the Vietnamese Embassy or Consulate in Japan are already authenticated and are more practical.

Additional requirement: Vietnamese citizens are sometimes required to provide a 公証 (notarized) version of documents. Consult with the Vietnamese Embassy or Consulate in Japan (located in Tokyo, Osaka, and Fukuoka) for the most current requirements.

Thai Citizens {#thai}

Required documents:
- Valid Thai passport
- หนังสือรับรองความเป็นโสด (Certificate of Single Status / Certificate of Eligibility to Marry) — issued by the Thai Embassy or Consulate in Japan, or by the district office (Amphoe) in Thailand
- Certified Japanese translation of Thai documents

Documents obtained from Thai district offices in Thailand must be authenticated by the Thai Ministry of Foreign Affairs (Department of Consular Affairs) before being submitted in Japan. The most convenient approach is to contact the Royal Thai Embassy in Tokyo or the Thai Consulate in Osaka, which can issue or authenticate the required certificate.

European Union Citizens {#eu}

Requirements vary by EU country, but most EU countries are signatories to the Hague Apostille Convention, which simplifies authentication.

General requirements:
- Valid EU passport
- Certificate of No Impediment or equivalent single status document from your national authority
- Apostille certification on the document
- Certified Japanese translation

Specific notes:
- UK (post-Brexit): The UK issues a Certificate of No Impediment (CNI) through the General Register Office. The CNI requires an Apostille. As the UK is still an Apostille Convention signatory, this process remains the same post-Brexit.
- Germany: Issues an Ehefähigkeitszeugnis (Certificate of Capacity to Marry). Apostille required.
- France: Issues a certificat de coutume (legal capacity certificate) and extrait d'acte de naissance (birth certificate extract). Both require Apostille.
- Italy: Issues a Nulla Osta (no objection certificate). Apostille required.

6. International Marriage Certificates and Legalization {#international-certificates}

Apostille vs. Consular Legalization {#apostille}

Understanding the difference between these two authentication methods is crucial:

Apostille
- Available for countries that have signed the Hague Convention Abolishing the Requirement of Legalisation for Foreign Public Documents (1961)
- A single Apostille stamp/certificate from the issuing country makes the document valid in all other signatory countries, including Japan
- Japan joined the Hague Apostille Convention and began accepting Apostille-authenticated documents from March 2023
- Much faster and simpler than consular legalization

Consular Legalization (Chain Authentication)
- Required for countries NOT in the Hague Apostille Convention (including China, Vietnam, and others)
- The chain: Document → authenticated by issuing country's foreign ministry → authenticated by the Japanese Embassy/Consulate in that country
- More time-consuming and requires planning

Countries without Apostille commonly encountered in Japan:
- China (mainland)
- Vietnam
- Indonesia
- Myanmar
- Malaysia
- Cambodia
- Bangladesh

Citizens of these countries should plan significantly more time for document authentication — often 4 to 8 weeks if obtaining documents from their home country.

Registering Your Marriage in Your Home Country {#home-country}

Once you have married in Japan, you will likely need to register your marriage in your home country as well. This is called "dual registration" and is generally required for your marriage to be fully legally recognized internationally.

General process:
1. Obtain a certified copy of your Japanese marriage certificate (婚姻届受理証明書 or 戸籍謄本).
2. Have it authenticated with an Apostille from the Japanese Ministry of Foreign Affairs (MOFA). Japan's MOFA accepts Apostille applications at the Ministry of Foreign Affairs in Tokyo and at regional legal affairs bureaus.
3. Have the Apostille-certified document translated into your home country's language by a certified translator.
4. Submit the authenticated, translated marriage certificate to the appropriate registry office in your home country (specific requirements vary widely by country).

U.S. citizens: Report the marriage to the U.S. Embassy or Consulate for inclusion in the Consular Report of Birth Abroad (if applicable) and update your passport if you change your name. The U.S. does not have a central marriage registry, but your Japanese marriage certificate will be recognized by U.S. authorities once properly authenticated.

UK citizens: Register the marriage with the General Register Office through the Foreign & Commonwealth Development Office process. Submit an authenticated copy of your Japanese marriage certificate.

Chinese citizens: Report the marriage to the Chinese Embassy or Consulate in Japan, which will notify the relevant authorities in China to update your civil registration records.

Korean citizens: Korean citizens must report the marriage to the Korean Consulate in Japan within 3 months. Bring your koseki extract showing the marriage and your Korean documents.

7. Changing Your Residence Status After Marriage {#residence-status}

One of the most significant practical consequences of marrying in Japan — particularly for foreigners who marry a Japanese national — is the change in available immigration status.

Spouse of Japanese National Visa (日本人の配偶者等) {#spouse-visa}

The "Spouse of Japanese National" status of residence (在留資格: 日本人の配偶者等) is specifically for:
- Foreign nationals married to Japanese citizens
- Children of Japanese citizens born to foreign women
- Special permanent residents (under specific circumstances)

Key features of this visa:
- No work restrictions: You may work in any occupation without limitation
- Renewable: Typically issued for 6 months, 1 year, or 3 years; renewable indefinitely as long as the marriage continues
- Path to permanent residency: After 3 years of holding this status (5 years total in Japan with at least 3 years on spouse visa), you may apply for permanent residency
- Path to naturalization: Expedited naturalization eligibility (3 years of residence in Japan while married to a Japanese national, or having been married for 3+ years and residing in Japan for 1+ year)

Required documents for Spouse of Japanese National visa application:
- Application for Certificate of Eligibility (在留資格認定証明書) or Change of Status of Residence application (在留資格変更許可申請)
- Photograph
- Passport and Residence Card
- Copy of your Japanese spouse's koseki (within 3 months of issuance)
- Proof of marriage in Japan (marriage certificate or koseki extract showing the marriage)
- Documents proving the couple's relationship is genuine (photos, communication records, etc.)
- Your Japanese spouse's tax and income documents (tax certificate, withholding tax certificate, etc.)
- Statement of reason for marriage (申請理由書)
- Questionnaire about the couple's relationship and living situation

Authenticity requirement: Immigration authorities carefully scrutinize spouse visa applications for "sham marriages" (偽装結婚). Be prepared to provide extensive evidence that your marriage is genuine — including photos together, communication records, shared finances or lease agreements, and in some cases, an in-person interview at the immigration office.

Spouse of Permanent Resident Visa (永住者の配偶者等) {#permanent-resident-spouse}

If you marry a foreign national who holds permanent resident status in Japan (rather than a Japanese citizen), you may apply for "Spouse of Permanent Resident" status (在留資格: 永住者の配偶者等).

This status carries similar benefits to the Spouse of Japanese National status, including no work restrictions. However, the path to permanent residency is slightly different — you typically need 5 years of residence in Japan (1 year on spouse status after the marriage).

Changing Status Within Japan {#change-within-japan}

If you are already living in Japan on a different visa (student visa, work visa, etc.) and marry a Japanese national or permanent resident while in Japan, you can apply to change your status of residence.

Process:
1. Register the marriage at your local municipal office (as described above).
2. Obtain your updated koseki extract showing the marriage.
3. Prepare the required immigration documents.
4. Submit a Change of Status of Residence Application (在留資格変更許可申請) to your regional Immigration Services Agency office.
5. Wait for processing (typically 1 to 3 months).
6. Once approved, receive your new Residence Card showing the updated visa status.

Important: You must continue to hold a valid visa status throughout this process. Do not let your current visa expire before the change is processed. If necessary, apply for an extension of your current status while the change application is pending.

Cost: The application fee for a Change of Status application is ¥4,000 (revenue stamp, shunyu inshi, available at convenience stores and post offices).

Applying from Abroad {#applying-from-abroad}

If your foreign national spouse is abroad and wishes to come to Japan to live after marrying a Japanese citizen or permanent resident in Japan, the process involves:

Register the marriage in Japan (can be done by the Japanese spouse alone, with the foreign national's signature on the form).
Apply for a Certificate of Eligibility (COE) (在留資格認定証明書) at the Immigration Services Agency in Japan. This is typically done by the Japanese sponsor (spouse) on behalf of the foreign national.
Once the COE is issued (typically 1 to 3 months processing time), send it to the foreign national abroad.
The foreign national applies for a Spouse of Japanese National visa at the Japanese Embassy or Consulate in their home country, submitting the COE and other required documents.
Upon receiving the visa, the foreign national can travel to Japan and will receive their Residence Card upon arrival at immigration.

8. Marriage Between Two Foreigners in Japan {#foreigner-foreigner}

Two foreign nationals can legally marry in Japan, even if neither is a Japanese citizen. The process is similar to the above but with a few important distinctions.

Key considerations:

Both parties need documents from their respective home countries. Each person must provide their home country's Certificate of Eligibility to Marry (or equivalent). This means dealing with two separate embassies or consulates, each with their own requirements and timelines.
No Japanese koseki is created. Since neither party is a Japanese national, no entry is made in the koseki system. Japan will register the marriage in a separate record system for foreign nationals.
The marriage may need to be separately recognized in both home countries. Since neither party has a koseki, the main proof of marriage in Japan will be documents issued by the municipal office.
Immigration status is not automatically affected. Marrying another foreigner in Japan does not grant either party any new visa rights in Japan. To remain in Japan, both parties must independently maintain valid residence status.
Home countries may not automatically recognize the Japanese marriage. Both parties should take active steps to register the marriage in their respective home countries to ensure full international legal recognition.

Special case — third-country marriages: If two foreigners from the same country marry in Japan, their home country's embassy should be notified. The marriage certificate can typically be registered at their shared home country's embassy or consulate in Japan.

9. Common Challenges and How to Overcome Them {#challenges}

Challenge 1: My Home Country Doesn't Issue a Certificate of Eligibility to Marry

Solution: Some countries — particularly the United States — do not issue an official government certificate of this type. In such cases:
- Prepare a notarized affidavit of single status from your country's consulate in Japan.
- Some Japanese municipal offices accept a notarized personal declaration that you are single, in lieu of an official government document.
- Call ahead to your local municipal office and explain your situation. They often have experience with this and can advise on what they will accept.

Challenge 2: My Documents Are in a Language the Municipal Office Can't Verify

Solution:
- Always use a certified professional translator.
- The translation itself does not need official government certification in Japan, but it must include the translator's full name, address, and date.
- Consider using a translation agency that has experience with Japanese civil registration documents.

Challenge 3: The Municipal Office Keeps Rejecting My Application

Solution:
- Ask the office in writing for the specific reason for rejection and what exactly is needed.
- Consult with an administrative scrivener (gyosei shoshi 行政書士) who specializes in international marriages. These professionals navigate municipal and immigration bureaucracy regularly and can often resolve documentation issues quickly.
- If you believe the rejection is incorrect, you can request a review or escalate within the municipal government.

Challenge 4: My Previous Divorce Records Are in Another Country and Hard to Obtain

Solution:
- Contact your home country's embassy in Japan — many can request records on your behalf.
- If you were divorced in Japan, your divorce record will be in the Japanese court or municipal records and can be obtained from there.
- For foreign divorces, an authenticated copy of the divorce decree or final court order, with certified Japanese translation, is typically required.

Challenge 5: Language Barriers at the Municipal Office

Solution:
- Bring a Japanese-speaking person (friend, acquaintance, or hired interpreter) with you.
- Some city halls in major urban areas (Tokyo's special wards, Osaka, Yokohama, etc.) have multilingual staff or interpreter services. Call ahead.
- Prepare a written summary of your situation in Japanese to hand to the counter staff.
- The municipal office cannot legally refuse to accept your documents because of language; they must process your application.

Challenge 6: My Spouse and I Cannot Both Be Present

Solution:
- Only one spouse needs to be physically present to submit the Kon'in Todoke.
- The absent spouse must have signed the form in advance.
- The present spouse submits the completed, signed form along with all required documents.
- If neither party can be present, a representative (dairi) can submit, but requirements for this vary by municipality — call ahead.

10. Costs and Timelines {#costs-timelines}

11. Marriage Registration for Specific Situations {#special-situations}

If You Are Already Married Abroad {#already-married}

If you and your Japanese partner (or foreign partner) have already married in your home country through a legally recognized ceremony and registration, Japan will generally recognize this as a valid marriage once it is registered within Japan.

Process:
1. Obtain an authenticated copy of your home-country marriage certificate.
2. Have it authenticated with an Apostille or consular legalization.
3. Have it translated into Japanese.
4. Submit this, along with the Kon'in Todoke (still required) and your other documents, to your local municipal office.

Some municipal offices may want to verify the marriage through the foreign embassy before processing. This is called a jojun (準拠) check and is part of confirming the marriage is valid under your home country's laws.

Note: If you married abroad more than 3 months before submitting to a Japanese municipal office, you will need to explain the delay. Japan requires marriage notifications to be submitted within 3 months if the couple resides in Japan. Marriages that occurred abroad can technically be registered at any time, but you should prepare for questions.

If You Were Previously Divorced {#previously-divorced}

If either party has been previously married and divorced, you must prove the divorce is legally valid and complete. Required documents typically include:

Divorce certificate or final decree of divorce from the relevant court or registry
For Japanese nationals: their koseki, which will show the divorce
For foreign nationals: authenticated and translated foreign divorce documentation

As of April 1, 2024, the 100-day waiting period for women who were previously married has been abolished in Japan. There is no waiting period before remarrying.

Same-Sex Couples {#same-sex}

As of the time of publication (2026), Japan does not legally recognize same-sex marriage at the national level under the Civil Code. Same-sex couples in Japan currently cannot register their relationship as a marriage through the standard Kon'in Todoke process, regardless of whether they are Japanese nationals or foreign nationals.

Partnership Certificates (Patonashippi Shomeisho):
Many Japanese municipalities — including Tokyo, Osaka, Sapporo, Kyoto, and hundreds of others — issue partnership certificates (パートナーシップ証明書) for same-sex couples. These certificates:
- Are recognized by a growing number of local governments and some private companies
- Allow couples to act as next-of-kin in participating hospitals
- May be recognized for co-housing applications in some public housing
- Are NOT recognized at the national level for immigration or inheritance purposes

For foreign same-sex couples married abroad:
If you are two foreign nationals who are legally married in your home countries, Japan may or may not recognize your marriage for local purposes, but it will not grant immigration benefits based on same-sex marriage. Consult with an immigration specialist for your specific situation.

Legislative reform efforts are ongoing in Japan, and the legal landscape may change. Check for the most current status.

12. After Marriage: Administrative To-Do List {#after-marriage}

Once your marriage is registered, there are several additional administrative tasks to handle:

Immediately After Registration

[ ] Obtain multiple certified copies of your marriage certificate (at least 3–5)
[ ] Verify your Residence Card information is current
[ ] Begin gathering documents for visa status change (if applicable)

Within 2 Weeks

[ ] Update your juminhyo (resident registration) if your address changes
[ ] Notify your employer of your marriage (for health insurance and tax purposes)
[ ] Contact your home country's embassy or consulate to register the marriage

Within 1 Month

[ ] Apply for Change of Status of Residence (if applicable)
[ ] Update your bank account information if your name changes
[ ] Update your health insurance (kokumin kenko hoken or employer-sponsored insurance)
[ ] Notify the Japan Pension Service (Nihon Nenkin Kiko) if your name or coverage changes
[ ] Update your National Tax Agency registration if applicable

If You Change Your Name

Foreigners in Japan typically retain their home country name as it appears in their passport for official Japan residence purposes. A foreign national cannot typically adopt their Japanese spouse's family name (myoji) in Japan, as the koseki system records foreign nationals under their original name. However:
- Some Japanese municipalities will allow a foreign national's katakana name record to be updated if they legally change their name in their home country first.
- Your home country may allow you to adopt your spouse's name through your home country's name change process, and once updated in your passport, Japan records can be updated accordingly.

13. Frequently Asked Questions {#faq}

Q: Can I marry in Japan if I'm on a tourist visa?

A: Legally, there is no visa restriction on who can marry in Japan — you do not need to be a resident. However, practically, you will need to provide your home country's Certificate of Eligibility to Marry, which usually requires in-person visits to your home country's consulate. Being on a tourist visa also does not give you the right to remain in Japan after the marriage, so you would need to separately apply for a Spouse Visa (either from Japan or from abroad) to live with your spouse in Japan.

Q: How long does the marriage registration process take at the city hall?

A: If all your documents are complete and in order, the submission itself typically takes 30 minutes to 2 hours at the counter. Some offices process it same-day and immediately issue the Certificate of Acceptance of Marriage. Others may take a few days to fully process and update the koseki.

Q: Is a wedding ceremony required to legally marry in Japan?

A: No. A wedding ceremony — whether at a shrine, church, hotel, or anywhere else — is entirely optional and has no legal effect. The legal marriage in Japan is completed entirely through the paperwork submitted to the municipal office. Many couples have elaborate ceremonies without ever being legally married, and many legally married couples have no ceremony at all.

Q: My Japanese partner and I are already living together. Will that help our visa application?

A: Yes. Evidence of cohabitation — a joint lease agreement, shared utility bills, photos taken at your shared residence — is useful evidence that your marriage is genuine. Immigration officers look for signs that a couple is in a real relationship, and cohabitation is one positive indicator.

Q: What if my home country has different requirements for international marriage?

A: Your home country's requirements are legally separate from Japan's requirements. You need to ensure your marriage meets both sets of requirements. For example, some countries require a citizen to follow specific procedures (such as publishing banns or obtaining government approval) before marrying abroad. Failing to comply with your home country's requirements may mean your Japanese marriage is not recognized in your home country, even if it is fully legal in Japan.

Q: Can I register my marriage at any city hall in Japan, or does it need to be near where I live?

A: You can register at the municipal office where either spouse has their registered address, OR at the office where the Japanese spouse's koseki is registered (which may be in a different city). You are not limited to the office closest to your current home.

Q: How is my spouse's name entered on the marriage form if they have a name that doesn't fit Japanese writing systems?

A: Foreign names are written in katakana on Japanese official documents. The municipal office will record the name in katakana based on the phonetic pronunciation, cross-referenced with the passport. Some offices may also record the name in the Roman alphabet in a separate field.

Q: What happens to my visa if my marriage ends in divorce?

A: If you are on a Spouse of Japanese National visa and your marriage ends in divorce, you are required to report the change to the Immigration Services Agency within 14 days. Your visa is not automatically cancelled at the moment of divorce, but you will need to either find a new basis for your residence status or leave Japan. Depending on circumstances, you may be able to apply for a Long-Term Resident status, particularly if you have children from the marriage living in Japan.

Q: Does marrying a Japanese national automatically give me permanent residency?

A: No. Marriage to a Japanese national gives you eligibility to apply for the Spouse of Japanese National visa status, but permanent residency must be separately applied for. After holding spouse status for 3 years (with at least 1 year of continuous residence), you may become eligible to apply for permanent residency (永住許可申請). The standard permanent residency requirement is 10 years of residence, but this is reduced to 5 years for spouses of Japanese nationals (with at least 3 years on spouse status).

Q: Can my partner's parents object to the marriage and stop it from being registered?

A: No. For adults (18 and older), parental consent is not required and parental objection has no legal effect on marriage registration in Japan. Both parties simply need to be legally eligible under their respective national laws.

Q: What is an administrative scrivener (gyosei shoshi) and do I need one?

A: A gyosei shoshi (行政書士) is a licensed professional who specializes in preparing and submitting administrative and government documents in Japan. They are not lawyers but have deep expertise in immigration, civil registration, and other administrative procedures. For complex marriage and visa situations — especially where documents are difficult to obtain or where previous marriages, unusual visa statuses, or other complications exist — hiring an administrative scrivener can save significant time and stress. They typically charge ¥50,000 to ¥150,000 for a full spouse visa application.

Q: Is it possible to have a proxy marriage in Japan?

A: Japan does not recognize proxy marriages (where a person marries through a representative acting in their place). Both parties must sign the Kon'in Todoke form themselves, though only one party needs to physically appear at the municipal office to submit it.

Q: What if I don't speak Japanese — can I bring an interpreter?

A: Absolutely. You are welcome to bring an interpreter. There is no formal requirement for the interpreter. Some major city halls in international cities like Tokyo and Osaka have multilingual support, but bringing your own is advisable. The municipal office staff cannot refuse to process your application due to language differences, though communication difficulties may slow the process.

Q: How do I prove the authenticity of my foreign documents?

A: Authentication is done through either Apostille (for countries in the Hague Apostille Convention) or consular legalization (for countries not in the Convention). In both cases, the chain of authentication provides the Japanese municipal office with confidence that the documents are genuine government-issued records.

14. Conclusion {#conclusion}

Registering a marriage in Japan as a foreigner is a multi-step process that requires careful preparation, but it is entirely manageable if you approach it methodically. The key steps are:

Understand what your home country requires and contact your embassy or consulate in Japan early to obtain your Certificate of Eligibility to Marry.
Gather and authenticate all documents — ensure all foreign-language documents are properly translated and authenticated via Apostille or consular legalization.
Visit your municipal office prepared — call ahead, confirm required documents, and bring a Japanese-speaking companion if possible.
Submit the Kon'in Todoke and obtain your marriage certificates on the same day.
Register the marriage in your home country to ensure full international legal recognition.
Update your visa status if you are now eligible for a Spouse of Japanese National or Spouse of Permanent Resident status.

Japan's administrative system can seem opaque and demanding, but thousands of international couples successfully complete this process every year. The paperwork is extensive, but the actual legal marriage is simple — no ceremony, no officials, no fee. Just forms, stamps, and patience.

If at any point the process feels overwhelming, do not hesitate to consult an administrative scrivener who specializes in international marriages and immigration. Their expertise can be invaluable, particularly when documents are complex or municipal office requirements are unclear.

Marriage in Japan opens a new chapter — not just personally, but administratively. With the right preparation, you can navigate the paperwork and focus on what truly matters: building your life together in Japan.

This article provides general guidance based on Japanese law and procedures as of 2026. Laws and administrative requirements change regularly.
