Post-Birth Paternity Leave in Japan: 28 Days, Applications, and Benefits

Up to 28 days within the post-birth window

The basic entitlement is a total of four weeks, or 28 calendar days, within eight weeks after birth. Weekends and other days off count within a continuous leave period. You can use fewer than 28 days and split the entitlement into up to two periods.

Special timing rules apply when the actual birth differs from the expected date. The window starts from the earlier of those dates and extends through the post-birth eight-week period measured from the later date. Give your employer both dates and confirm the final eligible date before fixing the schedule.

Although fathers commonly use this leave, eligibility is not limited to fathers. It covers qualifying employees who are not taking postnatal maternity leave, including relevant adoption situations. Workers employed on a daily basis are excluded.

How it differs from ordinary childcare leave

Ordinary childcare leave can be extended to 18 months or two years when the relevant conditions are met. You may take ordinary childcare leave after using post-birth paternity leave. Treat support immediately after birth and the later division of care as separate planning needs.

For example, one period might cover discharge from hospital and another the end of help from relatives. To split post-birth paternity leave, request both periods together in the initial application. Do not assume you can add a second period later without following that requirement.

Fixed-term contracts and recent hires

Fixed-term employees may qualify. The contract, including renewals, must not clearly be due to end by the date six months after the day following the expiry of eight weeks measured from the later of the actual and expected birth dates. Check both the contract and the expected renewal position.

A labour-management agreement may exclude employees continuously employed for less than one year, those whose employment is clearly due to end within eight weeks of applying, and those scheduled to work two days a week or fewer. Non-regular employment alone is not a sufficient reason to assume you cannot take leave.

Prepare the application before the birth

The usual deadline is two weeks before the intended start. An employer that has taken the required measures and concluded a qualifying labour-management agreement may set a deadline of up to one month. Special circumstances, including an earlier-than-expected birth, can allow an application one week before the requested start.

1. Check the company rules, deadline, forms, supporting documents, and pay arrangements.
2. List the expected birth date and both proposed periods if splitting the leave.
3. Arrange a handover and agree when contact during leave would be necessary.
4. Submit the application and confirm how to report a changed birth date or schedule.
5. Confirm who handles benefit and social insurance exemption applications, and when.

Discuss the care tasks as well as the dates: meals, care of older children, nighttime support, and administrative procedures. A schedule works better when it reflects the household's actual needs.

Separate the 67% benefit from the additional 13%

Leave entitlement and employment insurance benefits have different conditions. The post-birth childcare leave benefit generally requires at least 12 qualifying insured months in the two years before leave, along with the other eligibility requirements. Its basic formula is the daily wage at the start of leave × eligible benefit days × 67%, for up to 28 days. Caps apply, and wages paid during leave can reduce or eliminate payment.

Eligible recipients of the additional post-birth leave support benefit can receive another 13% for up to 28 days, producing a combined benefit rate of 80%. The claimant must take at least 14 days of qualifying leave within the applicable window, among other conditions. A spouse generally also needs at least 14 days of leave, but exceptions apply, including a spouse taking postnatal maternity leave, not employed, or self-employed. Neither “both parents must always take 14 days” nor “everyone receives 80%” is accurate. Confirm your household's circumstances with the employer or Hello Work.

These benefits do not necessarily mean continued normal salary, and payment may not arrive on the usual payday. Use the guide to budgeting until the next payment to map expenses before leave starts.

Work during leave requires a separate process

Working during post-birth paternity leave requires the prescribed process, including a labour-management agreement, an employee request, and individual consent. Limits on working days and hours depend on the leave period. The employer cannot simply require attendance for its own convenience.

If you plan employment or side work during leave, check the rules for this specific leave and benefit. Do not apply ordinary childcare leave thresholds automatically. The guide to side jobs during ordinary childcare leave explains that separate situation.

Later absences for a child's illness or vaccinations involve another scheme. The child nursing and related leave guide can help you plan care after returning to work as well as immediately after birth.
