Free Guide to Hiring a Family Lawyer
Marriage in Akishima is governed primarily by national Japanese law - the Civil Code and related statutes - with municipal procedures handled by Akishima City Office. To create a legally recognized marriage you must submit a marriage notification - kon-in todoke - at the city office where one spouse is registered. Japanese family registration - koseki - will record the marriage for Japanese nationals. For marriages involving a foreign national there are additional documentary and immigration considerations. Fundamental requirements include legal capacity to marry, minimum age, lack of an existing marriage, and absence of a prohibited degree of kinship.
Not every marriage issue requires a lawyer, but legal advice is often useful when matters are complex or contested. Common situations where people seek legal help include international marriages with documentation or visa issues, contested divorces, disputes over child custody or visitation, child support and spousal support claims, division of assets and debts, protection from domestic violence, annulment or disputes about the validity of a marriage, registering foreign marriage documents in Japan, and inheritance questions that arise after marriage. A lawyer experienced in family law can explain your rights, prepare or review documents, represent you in family court, and help negotiate settlements.
Key points to know about local practice and law in Akishima and Japan generally are:
- Registration: A marriage becomes legally effective only when a marriage notification is accepted at a municipal office. In Akishima this is handled by Akishima City Office - Family Register and Resident Registration sections. Forms are typically in Japanese.
- Minimum age: Both parties must meet the statutory minimum marriage age. Recent revisions to the Civil Code set the minimum age at 18 for both sexes.
- Single status and bigamy: Neither party may already be married. Bigamy is prohibited. If previously married, proof of divorce or death certificate of the former spouse will be required.
- Family register (koseki): For Japanese nationals the marriage will be entered into the koseki. If both spouses are Japanese they will be recorded in the same family register entry. If one spouse is a foreign national the foreigner will be recorded in a supplementary or foreign-related section and additional documents may be required.
- Surname rule: Japanese law requires married spouses to have the same surname. Spouses may choose which surname to use, but one common Japanese family name must be selected for the family register. This rule applies to the legal status in Japan - how non-Japanese spouses use their names on passports or foreign documents depends on their home-country rules.
- International documentation: Foreign documents - such as certificates of no impediment, birth certificates, divorce decrees or foreign marriage certificates - often need to be translated into Japanese and may need certification or notarization by the issuing country's embassy or consulate.
- Divorce and family court: Many divorces are resolved by mutual agreement and registered at the municipal office. Contested divorces or disputes about custody, visitation, maintenance, and property division go to family court. Japanese family court can also offer mediation services.
- Child custody and support: Japan generally grants sole parental authority after divorce. Child support follows statutory guidelines but is often determined by agreement or court order. Enforcement of support orders has specific procedures under Japanese law.
- Domestic violence protections: Victims can seek civil protection orders through family court and criminal protection through the police. Municipal and prefectural support services may be available for victims.
To register a marriage you submit a completed kon-in todoke form to Akishima City Office - Family Register and Resident Registration section. Both spouses normally sign the form. Bring valid identification and any required supporting documents such as a koseki tohon for a Japanese spouse or a certificate of legal capacity to marry for a foreign spouse. If documents are in a foreign language you will generally need a certified Japanese translation.
Usually both parties need to bring identification. A Japanese spouse should bring a copy of their family register (koseki tohon) if requested. If either spouse has a previous marriage, proof of divorce or death certificate of the former spouse will be required. The city office will advise on any additional required documents.
Yes, foreigners can marry in Japan. Required documents vary by nationality but commonly include a certificate of legal capacity to marry or single status affidavit issued by the foreigner’s embassy or consulate, passport, birth certificate, and Japanese translations. The embassies often provide guidance on their specific requirements. Akishima City Office will also set out what documents they require for registration.
Under current national law marriage is defined as a union between a man and a woman and same-sex marriage is not legally recognized nationwide. Some local governments in Japan issue partnership certificates for same-sex couples to help access certain local services and facility recognition - these certificates are not equivalent to national marriage recognition. For the status in Akishima specifically, check policies at Akishima City Office or municipal announcements.
Japanese law requires spouses to have the same surname. When a marriage is registered, the couple indicates which surname they will use in the family register. Either spouse’s surname can be chosen. Non-Japanese partners are not automatically required to change their passport name - passport and foreign documentation rules depend on the issuing country.
If you are in immediate danger call the police. For legal protection you can apply to family court for a protection order against the abuser. Akishima and Tokyo prefecture also provide victim support services, counseling, and temporary shelter options through municipal or prefectural agencies. A lawyer or local victim support organization can help you understand options for protection orders, divorce, custody, and criminal reporting.
Japan follows principles of equitable distribution of marital property and debts, relying on factors such as financial and non-financial contributions, length of marriage, and future needs. There is no fixed formula. Many divorces are settled by agreement on division. If no agreement is reached the family court will decide. It is advisable to document financial contributions and consult a lawyer before signing any settlement.
Japan typically grants sole parental authority after divorce. In practice, custody often goes to one parent - frequently the mother. Visitation arrangements and child support are matters for the parents to agree on or for family court to decide. If you are a foreign national concerned about international relocation or enforcement of custody orders, get early legal advice because cross-border issues can be complex.
If you married overseas you may need to register the marriage with the Japanese authorities if you or your spouse are Japanese nationals. For non-Japanese spouses, registering an overseas marriage in Japan can involve submitting the foreign marriage certificate with translations and certification. Requirements depend on nationality and circumstances, so check with Akishima City Office and your embassy.
