Free Guide to Hiring a Family Lawyer
Tokorozawa is a city in Saitama Prefecture where marriage is governed by national Japanese laws and implemented locally by the city hall. In Japan, marriage is a civil act that becomes legally effective when registered with the local government office, not merely by a ceremony. The key processes involve the Civil Code and the Family Register Act, and Tokorozawa City handles the registration, copy requests, and related documentation for residents.
Practically, couples file a written notification known as a “konin todoke” at the Tokorozawa City Hall or a designated ward office, and the city updates the family register (koseki) accordingly. Foreign nationals must provide additional documents such as birth certificates, certificates of no impediment, and translations, all of which must be presented to complete the registration. Once processed, the marriage is recognized nationwide under Japanese law.
Marriage in Japan is established by civil registration with the local government and by the rules in the Civil Code and Family Register Act.

Notes for Tokorozawa residents: you will typically submit marriage notifications at the city hall desk that handles civil registration. If one party is foreign, you may need to present translated documents and possibly apostilles or legalization depending on outbound or inbound requirements. Always verify required documents with the Tokorozawa City Hall before your appointment.
You normally need valid IDs, birth certificates, and a completed konin todoke form. Foreign nationals often require translated documents such as birth certificates and certificates of no impediment. Check with Tokorozawa City Hall for a current list of required items.
Both parties must appear to submit the notification, with translations and any apostille or legalization as required. The city may request additional documents to confirm identity and eligibility. An attorney can help assemble and translate materials efficiently.
Residency in Tokorozawa is not strictly required if both parties can complete the registration and present the necessary documents. In practice, many couples file at the local city hall where at least one party resides or works.
Minors generally require parental consent under national law, and the age rules changed with the 2022 reforms. Consult a lawyer for case-specific guidance on consent requirements and steps to legally marry.
Processing is typically completed on the day of submission if documents are in order. If documents require translations or corrections, processing may take longer. Always confirm the expected timeline with the city hall staff.
Submitting the registration itself usually has no separate fee, but you may pay for copies of the koseki and for marriage certificates. Exact costs vary by document type and municipality.
A wedding ceremony is a social or religious event and not legally binding. A marriage registration with the city hall is the legal acts that creates the marital status and updates the koseki.
The koseki is the Japanese family registry. When you marry, the koseki is updated to reflect the new legal status and any changes to family relationships. Copies of the koseki can be requested for various official purposes.
Japan does not nationwide recognize same-sex marriages; some localities issue partnership certificates. Tokorozawa adheres to national law, though local guidance on recognition may vary. Consult a lawyer for current local options.
Hiring a lawyer is not required, but it can help with complex issues such as international documents, prenuptial agreements, or cross-border asset planning. A local lawyer familiar with Tokorozawa procedures can save time and reduce errors.
A prenuptial agreement is a contract between spouses about property and financial arrangements. It must be in writing and may be subject to Japanese contract and family law rules, with enforcement depending on the terms and court interpretation.
Custody decisions prioritize the child’s best interests and can involve mediation or court if needed. Both parents may be granted parental authority, or one parent may obtain sole custody depending on circumstances and the court’s assessment.
