Birth Registration and the 14-Day Rule
Birth registration in Japan means filing the shussei todoke (出生届), the legal notification of a birth, within 14 days of the child's birth under the Family Register Act.1 Missing that window does not stop the registration from going through, but it can trigger a fine and stall the time-sensitive procedures that depend on the registration already being on file.
Procedures, fees, and requirements can change. Confirm current details at the Ministry of Justice's family register (koseki) information pages or your local ward or city office.
Overview
The shussei todoke is the starting point of a child's official record in Japan, regardless of the child's eventual nationality. An accepted shussei todoke is what triggers the family register (koseki) entry for a child with a Japanese parent, the residence record (juminhyo) entry that every child receives, and, for a child with no Japanese-national parent, the clock on that child's own immigration status.
The core procedure is the same everywhere in the country. The 14-day deadline, the required documents, and the ward-office filing steps do not vary by prefecture; only optional add-ons, most notably online filing, vary by municipality.
Several Japanese terms recur throughout this article. The table below glosses them on first appearance.
| Term | Reading | Meaning |
|---|---|---|
| 出生届 | shussei todoke | The birth notification form itself |
| 出生証明書 | shussei shoumeisho | The birth certificate, physically the other half of the same form |
| 母子健康手帳 | boshi kenkō techō | Maternal and child health handbook |
| 戸籍 | koseki | Family register (Japanese nationals only) |
| 住民票 / 住民基本台帳 | juminhyo / jumin kihon daichou | Resident record / Basic Resident Register |
What is the shussei todoke?
The shussei todoke is a single two-part paper form. A parent, or another eligible registrant, fills in and signs the left half.12
The right half is the shussei shoumeisho, the birth certificate. The attending physician, midwife, or other qualified attendant completes and signs that half, in the format set by ministerial ordinance.12
Because the two halves are physically one document, a parent cannot submit the shussei todoke until the attending physician or midwife has finished their half. Hospitals in Japan typically complete this before the family is discharged.2
Who must file and when
The registrant (届出人) is normally the father or the mother. If the parents are not married to each other, the mother is the registrant.3
If neither parent is able to file, a person living in the same household, or the physician or midwife who attended the birth, may file instead.3
Filing must occur within 14 days of the birth if the child is born in Japan, or within 3 months if the child is born abroad.1 The 14-day period is counted starting from the day of the birth itself, under Family Register Act Article 43, rather than from the following day, which is the Civil Code's ordinary default for counting a period.1
Family Register Act Article 43 treats the day of birth as day one of the 14-day window, not the day after. Parents who count "14 days after the birth" rather than "14 days including the birth date" risk being one day late.1
If the 14th day falls on a weekend or public holiday, several municipalities extend the effective review deadline to the next business day, though a night or holiday drop-off is generally still available on the deadline date itself.24
Required documents
| Item | Amount | As of | Notes |
|---|---|---|---|
| Filing the shussei todoke itself | ¥0 (no fee) | 2026-075 | Standard in-person or paper filing |
| 届書記載事項証明書 (certified copy of the notification's recorded content) | ¥350 per copy | 2026-076 | A separate, optional product; not needed just to file |
| MynaPortal online filing | ¥0 (no additional fee) | 2024-08-307 | Only available where the eligibility conditions below are met |
The figures above are current as of 2026-07; confirm current fees with your local ward office. Filing the shussei todoke itself carries no fee anywhere in the country.
From the hospital or midwife
The shussei shoumeisho is not a separate document from the shussei todoke. It is the right-hand section of the same physical form, completed by the physician, midwife, or other attendant in the order the ministerial ordinance prescribes.12
Ward offices keep the original submitted form and do not return it. Several ward-office guidance pages explicitly instruct parents to make and keep a copy before submission.5
From the parents
Parents must bring the maternal and child health handbook (母子健康手帳) at the time of filing, or, if it is unavailable, a delivery-confirmation sticker or slip in its place.35
For foreign-national parents
| Document | Required from | Notes |
|---|---|---|
| The combined shussei todoke / shussei shoumeisho form | All parents | The physician or midwife must have already completed their half |
| Maternal and child health handbook | All parents | Or the delivery-confirmation slip if unavailable |
| Residence card, special permanent resident certificate, or passport | Foreign-national parents | Confirms parents' identity and status |
| Marriage documentation | Where applicable | Needed if the parents are married |
The table above reflects the checklist confirmed for foreign-national parents.8
The child's name must be written in katakana, with a romanized rendering noted alongside it, when the parents are not Japanese nationals. Parents whose own script uses Chinese or Korean characters may instead register the child's name using kanji permitted for use in Japan, if they wish.8
The characters usable in any child's name, since the name is recorded in the form's Japanese-script fields, are limited to jōyō kanji, the supplementary jinmeiyō kanji list, and hiragana or katakana. An unlisted character can be rejected at the counter, regardless of the parents' nationality.9
A child born in Japan with no Japanese-national parent may remain in the country without an independent status of residence for up to 60 days from birth. Staying beyond 60 days requires applying for acquisition of status of residence within 30 days of the birth.10 The application steps themselves, and what happens if that window is missed, are outside the scope of this article.
The filing procedure
The diagram below shows both filing paths and where they converge.
In person at the ward office
Parents may file the shussei todoke at the ward or city office covering the parents' registered domicile (本籍地, relevant mainly where at least one parent is Japanese), the registrant's place of residence, or the place of birth.32
Outside normal business hours, ward offices generally accept the form at a night or holiday drop-off window. That window can only receive the paperwork; a staff member checks the content and attachments on the next business day, and may ask the family to return if something is missing, such as the health-handbook stamp.115
Online via MynaPortal
Since August 30, 2024, MynaPortal, the Digital Agency's national online-government portal, has offered a digital shussei todoke submission option. A registrant can submit the notification together with a smartphone-photographed image of the physician- or midwife-completed birth-certificate half, without an in-person ward-office visit (as of 2024-08-30; confirm current availability and conditions with the Digital Agency or your municipality).7
The online option requires that both of the child's parents hold Japanese nationality, or, for a child born to unmarried parents, that the mother alone hold Japanese nationality. A family in which either parent is not a Japanese national is not eligible for this option and must file the paper form (as of 2026-07).7124
Additional conditions apply beyond nationality. The registrant must hold a My Number Card with an active digital certificate; the birth must have occurred in Japan; the filing municipality must be the parents' registered-domicile municipality, and that municipality must support the feature; the child's name must use kanji available in the MynaPortal system; and only one parent, not both jointly, can be listed as registrant online, so couples who want both parents listed as joint registrants must use the paper form instead (as of 2026-07).124
Municipal rollout has been staggered rather than simultaneous nationwide. Hachioji City enabled the feature from November 1, 2024, and Yokohama City enabled it separately from December 1, 2025 (as of 2026-07).124 Availability varies by municipality; parents should confirm directly with their own registered-domicile ward or city office whether, and since when, it is supported.
Yokohama City's own guidance notes that online submissions take several days to review before formal acceptance, and recommends filing in person instead when a family needs the accepted record urgently (as of 2025-12).4
Timing and early filing
Filing well before the 14-day deadline, rather than on the last permissible day, avoids the compounding effect of the downstream procedures covered below that depend on the shussei todoke already having been accepted.1314
The dual-side procedure
The diagram below contrasts the Japan-side filing with the separate home-country process that some families also need.
Japan-side registration only vs. home-country reporting
Filing the shussei todoke at a Japanese ward office satisfies only the Japan-side legal requirement. It does not itself register the birth with a foreign parent's home country, and it does not itself confer or record foreign citizenship.15
For a child born in Japan with a U.S. citizen parent, the separate U.S.-side process is a Consular Report of Birth Abroad (CRBA), filed with the U.S. Embassy or a consulate using Form DS-2029. Required supporting items include the child's Japanese-issued birth record, proof of the U.S. citizen parent's citizenship, the parents' marriage or divorce documentation where applicable, and government-issued photo ID; a filing fee applies, and the CRBA can be filed at any point before the child's 18th birthday (as of 2026-07; confirm current fees and requirements with the U.S. Embassy or a consulate).15
The CRBA process illustrates only one country's approach. Whether a home-country report is required at all, its deadline, its required documents, and its fee are set entirely by the relevant foreign country's own nationality and civil-registration law, and this should not be treated as a universal "home-country side" procedure.15
Timing with the ISA 30-day rule
For a child with no Japanese-national parent, both the 60-day residency grace period and the 30-day status-of-residence application deadline run from the child's birth date itself, not from the date the shussei todoke happens to be filed.10
The status-of-residence acquisition application filed with the Immigration Services Agency requires attaching a certificate of acceptance of the birth notification among its supporting documents, per an administrative-scrivener firm's guidance rather than the agency's own published document checklist (limitation: not independently confirmed against an Immigration Services Agency primary source). In practice, this means the shussei todoke needs to have already been filed and accepted before the immigration application can be completed, so delaying the shussei todoke narrows the family's working time inside the 30-day window even though the two deadlines are legally separate.13
A child with no Japanese-national parent needs a certificate of acceptance of the birth notification to complete the status-of-residence acquisition application. Filing the shussei todoke late does not move the 30-day deadline, it only leaves less time to gather everything else the application requires.13
Full procedural detail on the status-of-residence application itself, including the required forms and the practical limits of the 60-day grace period, is outside the scope of this article.
Timeline and consequences
Several deadlines run in parallel from the same starting point, the child's birth date, rather than one after another.
| Deadline | Window | Applies to | Source |
|---|---|---|---|
| Shussei todoke (birth in Japan) | 14 days from birth | All births in Japan | 1 |
| Shussei todoke (birth abroad) | 3 months from birth | Births outside Japan | 1 |
| Child benefit (jido teate) application | 15 days from birth | Resident families, national program | 14 |
| Status-of-residence application | 30 days from birth | Children with no Japanese-national parent | 10 |
| Residency grace period | 60 days from birth | Children with no Japanese-national parent | 10 |
The child-benefit window above reflects the program as most recently reformed (as of 2024-10; confirm current amounts and windows with the Children and Families Agency); the other deadlines are set directly by statute and do not carry the same year-to-year revision risk.
The 14-day window explained
The 14-day filing period, or 3 months for a birth abroad, is set by Family Register Act Article 49 and counted from the day of birth under Article 43.1
What happens if you miss the deadline
A person who fails to file within the required period without justifiable reason faces a fine (過料) of up to ¥50,000 under Family Register Act Article 135.1
Ward offices still accept and process a late-filed shussei todoke. The statutory fine is a separate, court-administered matter, referred by the municipality to a summary court, and it does not itself block registration.1
Filing without justifiable reason after the deadline can bring a fine of up to ¥50,000 under Family Register Act Article 135. Registration still proceeds either way, but how often, or under exactly what criteria, that fine is actually referred to a summary court in practice could not be confirmed from primary sources for this article; treat the fine as a real statutory risk rather than a routine formality.1
Why prompt filing matters
Japan's national child benefit (児童手当) requires a separate application within 15 days of the birth, a different, national-program deadline from the 14-day shussei todoke window. Late applications generally forfeit benefit-months already passed (as of 2024-10).14
Municipality-administered pediatric medical-cost subsidy programs also carry their own application windows measured from the birth date; one example municipality requires application within 3 months of birth to receive the subsidy retroactive to the birth date itself (as of 2026-07, one municipality's rule, not a national standard).16 These programs and their age caps vary by municipality and are not detailed further here.
Because the child-benefit application, the medical-subsidy application, and a foreign-only child's own status-of-residence application typically require proof that the shussei todoke has already been accepted, filing it promptly, rather than waiting toward day 14, avoids compounding delays across these separate downstream deadlines.131416
What follows the birth registration
The koseki entry
The koseki (family register) system registers and certifies personal-status facts, including birth, marriage, and death, for Japanese nationals. Birth notification is listed among the standard koseki-related procedures handled at municipal counters under Legal Affairs Bureau oversight.17
Where at least one parent is a Japanese national, an accepted shussei todoke results in the child being entered into that parent's koseki. The detailed mechanics of how that entry is structured are covered in the article Koseki: Japan's Family Register Explained.17
The juminhyo entry
Since a July 9, 2012 amendment to the Basic Resident Register Act, foreign residents, including mid- to long-term residence-card holders and special permanent residents, are recorded in the same resident basic register (juminhyo) system as Japanese nationals. This replaced the former separate Foreign Registration Act framework.18
An accepted shussei todoke results in a resident-record entry for the child, whether or not the child has, or will have, a koseki entry. This is how a foreign-national newborn without their own status of residence is still administratively on the books during the 60-day grace period described above. The mechanics of this record are covered in the article Jūminhyō: Japan's Residence Record Explained.18
Dual-nationality implications
A child born to at least one Japanese-national parent generally acquires Japanese nationality at birth. If the child also acquires a foreign nationality, for example through the other parent or through that country's own citizenship rules, the child is a dual national.19
Under the Nationality Act as amended effective April 1, 2022, aligned with the Civil Code's lowering of the age of adulthood to 18, a person who becomes a dual national before turning 18 must choose one nationality by age 20. A person who becomes a dual national at or after 18 must choose within two years of that event.19
A narrower transitional rule lets people who were already 20 or older when the amendment took effect choose by age 22 instead. That age-22 provision is a one-time grandfather rule for an already-adult cohort at the time of the reform, not the standing rule for a child born under current law.19
This article previews the nationality-choice topic only. The full mechanism, the pledge-to-renounce procedure, and how strictly it is enforced in practice are outside the scope of this article.
Good to know
MynaPortal's digital option excludes most foreign-national families
MynaPortal's digital shussei todoke option requires both parents to hold Japanese nationality, or the mother alone for an unmarried couple (as of 2026-07; confirm current eligibility with the Digital Agency or your municipality). A household with any non-Japanese parent must file the paper form in person or by mail, regardless of what general "2024 digital filing" coverage might suggest.7124
A certified copy of the notification costs extra, even though filing is free
Filing the shussei todoke costs nothing, but a 届書記載事項証明書, a certified copy of the notification's recorded content sometimes needed for other procedures, costs ¥350 per copy at the ward office (as of 2026-07).56
The 14-day clock starts on the birth date itself, not the day after
Family Register Act Article 43 counts the day of birth as day one, unlike the Civil Code's general rule of excluding the first day of a period. Miscounting from the day after birth can put a family one day past the deadline without realizing it.1
MynaPortal's rollout varies by municipality and can take days to process
Where MynaPortal applies at all, it is rolling out municipality by municipality, not nationwide at once. Hachioji City enabled it from November 1, 2024, and Yokohama City separately enabled it from December 1, 2025 (as of 2026-07); other municipalities may not support it yet, and even where it is available, online review can take several days, making it unsuitable for families who need an accepted record urgently.124
Ward offices keep the original form, so copy it before submitting
Ward offices keep the original shussei todoke, including the attached physician or midwife birth-certificate section, and do not return it. Parents who later need to show what was submitted, for example for a foreign-national parent's own home-country reporting, should photograph or copy it first.5
