How to Register a Birth in Japan: 2026 City Hall & Newborn Guide

The first two weeks after a birth involve several procedures with different clocks. Treat the deadlines separately rather than assuming that one city-hall visit completes everything.

For the birth notification, the day the baby is born is counted as day one. If the 14th day falls on a municipal closure day, local rules may allow filing on the next open day; confirm this with the municipality where you will submit. Other procedures, especially Child Allowance and immigration, use different counting rules.

• Within 14 days of birth: submit the 出生届 (birth notification).
• Within 15 days from the day after birth: apply for Child Allowance at the municipality where the eligible recipient lives, or through the employer if the recipient is a public employee.
• Within 30 days of birth: if a foreign baby will remain in Japan for more than 60 days, apply to acquire an appropriate status of residence.
• As soon as practical: arrange the baby's health-insurance coverage and check the local child medical subsidy or medical-expense support program.
• As applicable: complete the child's embassy/consular registration and passport procedure, and decide whether to apply for a newborn My Number Card together with the birth notification.

Many municipalities accept family-register notifications outside normal office hours, but an after-hours desk may only take custody of the form. A family-register specialist may review the contents on the next business day, and the office can contact you if correction is needed.

Do not assume that Child Allowance, health insurance, medical subsidy, residence-certificate issuance, or other newborn procedures are available at the night or holiday desk. If you must submit the birth notification after hours, plan a second visit during business hours for the remaining procedures.

• After-hours acceptance rules differ by municipality.
• Content may be formally reviewed later rather than at the moment you hand it in.
• Birth-related certification in the Mother and Child Health Handbook may not be available after hours.
• Bring a reachable phone number and confirm the municipality's night/holiday location before going.

Several later procedures require evidence that the birth notification was accepted. Ask the counter which certificate is appropriate for the next step you need. A 出生届受理証明書 (certificate of acceptance of birth notification) is commonly useful for immigration or foreign administrative procedures, while a residence certificate may be useful after the baby's resident record has been created.

Certificate issuance is separate from the free birth-notification filing and may involve a municipal fee. If you need documents for an embassy, immigration office, employer, insurer, or overseas authority, ask that organization exactly which document, issue date, language, translation, or legalization requirement it accepts before buying multiple copies.

• Certificate of acceptance of birth notification, when requested by immigration or another authority.
• Residence certificate (住民票) after the baby's record is available, when needed.
• Copies or certified documents required by the embassy or consulate.
• Translations only where the receiving authority requires them.

A foreign child born in Japan who did not go through an immigration landing procedure may remain in Japan without a status of residence for up to 60 days from birth. If the child will stay beyond 60 days, an application to acquire a status of residence must be filed within 30 days of birth.

Do not wait for the 60th day. The 30-day application deadline is the practical one. Immigration may require proof of birth, household/residence information, the parents' residence documents, and materials matching the requested status. The appropriate status depends on the parents' own statuses and the child's legal relationship to them.

For residence cards issued on or after June 14, 2026, a photo is generally required from age one. A child who is still under age one when the residence card is issued does not need to submit a photo for that card.

• Birth notification deadline and immigration deadline are separate.
• If staying in Japan more than 60 days: apply for status acquisition within 30 days of birth.
• Complete the city-hall birth filing early because immigration commonly needs proof that the birth was registered.
• Check the Immigration Services Agency's current document list for the specific status you are applying for.

If the baby is a foreign national, contact the relevant embassy or consulate soon after the Japanese birth filing. Each country sets its own rules for recognizing a birth abroad, transmitting nationality, registering the child's name, and issuing a passport.

The embassy may ask for a Japanese certificate showing that the birth notification was accepted, a translation, parents' passports, marriage or relationship documents, and other records. Requirements differ widely, so use the embassy's official instructions rather than a generic checklist.

For foreign parents, the embassy/passport process and the Japanese immigration process should be planned together. A delay in obtaining one document does not automatically extend Japan's 30-day deadline to apply for status acquisition when the child will stay beyond 60 days.

• Ask the embassy which Japanese birth certificate or acceptance certificate it accepts.
• Confirm spelling and name order before the passport is issued.
• Check whether both parents must appear or sign.
• Keep the immigration deadline in view while the passport process is underway.

A newborn does not become covered simply because the birth notification was filed. If a parent is enrolled in employee health insurance, contact the employer or health-insurance administrator promptly about adding the child as a dependent. Japan Pension Service procedures include the Health Insurance Dependent Change Notification, and its 2026 guidance specifically includes a child being added because of birth.

If the household uses National Health Insurance, ask the municipality how to enroll the baby. Separately, many municipalities operate child medical-expense subsidy programs. Eligibility, application documents, effective date, and the way the subsidy is used differ locally, so complete the local application as soon as possible.

• Employee health insurance: contact the employer/insurer about dependent enrollment.
• National Health Insurance: apply through the municipality if the baby belongs in the household's NHI coverage.
• Child medical subsidy: check the municipality's own program and deadlines.
• Do not delay care while waiting for paperwork; ask the insurer or medical provider how later reimbursement is handled if coverage documents are still being processed.

Child Allowance (児童手当) requires a separate application. After a birth, apply within 15 days from the day after birth at the municipality where the eligible recipient lives. If the recipient is a public employee, the application is generally handled through the employer.

This is especially important after a return-home birth or when the birth notification was filed in another municipality. Filing the birth notification somewhere else does not transfer the Child Allowance application to your home municipality. Late applications can result in lost payments for missed months.

• Deadline: within 15 days from the day after birth.
• Apply at the recipient's home municipality unless the recipient is a public employee.
• Birth notification and Child Allowance are separate procedures.
• Ask what bank-account and identity information the municipality requires for the claim.

Once a qualifying newborn is registered in the resident record system, a My Number is assigned through the normal resident-registration process. The plastic My Number Card is optional and requires an application.

Since December 2, 2024, parents can apply for a newborn's face-photo-free My Number Card together with the birth notification. The combined application lets the legal representative specify the required PIN information and, when permitted, a delivery address such as a temporary stay location. J-LIS states that the card is delivered in principle about one week after the application is accepted, although it can take longer when the combined application is filed with a municipality other than the child's address municipality.

Using the simultaneous newborn procedure avoids a separate card-application trip in many cases. The newborn does not need to appear at city hall for that simultaneous application.

• My Number assignment and My Number Card application are different things.
• The newborn card can be requested together with the birth notification.
• The newborn version is issued without a facial photograph.
• If you file the combined form outside the address municipality, allow extra processing time.

Some births need extra coordination. Do not force a standard checklist onto a case involving unmarried parents, a home birth, uncertain parentage, unusual naming documents, or a missed deadline. City hall, the Legal Affairs Bureau, the Immigration Services Agency, or the relevant embassy may need to advise based on the exact facts.

For an unmarried Japanese father and foreign mother, nationality can be especially sensitive because the timing and legal effect of recognition matters. The Ministry of Justice explains that prenatal recognition can affect whether Japanese nationality is acquired at birth, while recognition after birth may lead to a different nationality-acquisition procedure if statutory conditions are met.

If the 14-day birth-notification deadline has already passed, contact the municipality immediately rather than waiting. If the child is foreign, separately check the immigration deadline because the 30-day status-acquisition clock is not reset by a late city-hall filing.

• Parents not married: confirm who is the legal declarant and whether recognition/nationality issues apply.
• Home birth: ask what proof of birth is required when there is no standard hospital-issued certificate.
• Names differ across documents: resolve spelling/order before passport and residence documents multiply the mismatch.
• Leaving Japan soon: still confirm birth registration, nationality/passport, and any immigration obligations before departure.
• Missed deadline: contact the competent municipality and, where relevant, immigration immediately.
