Japan Marriage Procedures: Legal Requirements and Documentation

Marriage in Japan requires submitting a konin todoke (marriage registration form) at any municipal ward office. Both parties must be of legal age (18 since 2022) and one must be a Japanese citizen or both must be legal residents. Required documents for a foreign spouse include a Certificate of No Impediment (konin yoken gubi shomeisho) issued by their country’s embassy or consulate in Japan, passport, and residence card. The certificate proves you are legally free to marry under your home country’s laws. Documents in languages other than Japanese require official translation.

The Process

The registration process itself takes about 30 minutes at the ward office counter. Two adult witnesses must sign the form (anyone is eligible, and ward office staff may assist if needed). Marriage becomes legally effective the moment the form is accepted, not at any ceremony. A church, shrine, or hotel ceremony has no legal standing without the ward office registration. Processing the form sometimes takes days if document verification is needed. After registration, the foreign spouse can apply to change their visa status to Spouse of Japanese National, which provides unrestricted work permission.

Marriage in Japan requires submitting a marriage registration form (kon-in todoke) to any city or ward office, signed by both partners and two witnesses. No ceremony is legally required. For international marriages, additional documents include: a Certificate of Legal Capacity to Contract Marriage from your home country’s embassy in Japan (format varies by country), Japanese translations of all foreign documents, passports, and residence cards. Processing takes one to several days depending on the municipality. After registration, the foreign spouse can apply for a Spouse of Japanese National visa, which provides unrestricted work permission and a path to permanent residency after one to three years. The visa change process takes one to three months through immigration. Name changes follow different rules: Japan does not require either spouse to change their surname in international marriages, unlike same-nationality Japanese marriages where the couple must register under a single family name.

The social aspects of Japanese marriage extend well beyond the legal registration. Engagement gifts (yuino) exchanged between families traditionally follow a prescribed set of symbolic items, though modern couples often substitute cash gifts. The go-between (nakodo) who introduced the couple traditionally plays a ceremonial role at the wedding, though arranged marriages through matchmaking have declined significantly. Same-sex marriage is not legally recognized in Japan as of 2025, though some municipalities issue partnership certificates that provide limited recognition. Public opinion surveys show growing support for legal recognition, particularly among younger Japanese.

After the Paperwork

Once married in Japan, the foreign spouse can apply for a Spouse of Japanese National visa (nihonjin no haigusha-tou) at the Immigration Bureau, which provides unrestricted work permission and initially grants a one-year or three-year stay with renewal. After three years of marriage and one year of continuous residence in Japan (or three years of continuous residence regardless of marriage duration), the foreign spouse becomes eligible to apply for permanent residence (eijuuken), which removes all visa restrictions and requires no further renewal.

The social dimensions of international marriage in Japan involve navigating family expectations on both sides. Meeting the Japanese partner’s parents (aisatsu, formal greeting visit) traditionally precedes the wedding and follows specific etiquette: bringing a formal gift (temiyage), dressing conservatively, and using polite language. The o-miai (formal introduction meeting) tradition has largely been replaced by natural courtship, but some families still arrange introductions through professional matchmakers (nakoudoin) or modern matching services. In-law relationships (shuutome to yome, mother-in-law and wife) carry cultural significance that Korean, Chinese, and Southeast Asian spouses often understand intuitively but that Western spouses may need to study explicitly. Building rapport through shared meals, seasonal gift exchange (ochuugen in summer, oseibo in winter), and regular communication demonstrates the respect that Japanese family culture expects.
