Paternity Leave in Japan: Your Rights, Pay, and the Law

Quick Answer: Fathers in Japan have a legal right to childcare leave — your employer generally cannot refuse. Since 2022 there's a dedicated "post-birth paternity leave" (産後パパ育休) of up to 4 weeks in the first 8 weeks (splittable), on top of regular childcare leave. It's paid (67%, and since 2025 up to ~100% of take-home if both parents take leave), and the law prohibits punishing you for taking it — companies have lost in court for trying. Yet most fathers still don't. This is the case for doing so.

If you're a father in Japan, the biggest barrier to taking leave usually isn't the rules — it's the fear that asking will cost you. This guide lays out what the law actually gives you: the right, the pay, and real protection from retaliation. Take it as encouragement, backed by the law.

Do dads have a legal right to paternity leave in Japan?

Yes — and it's stronger than most fathers realise. Under the Childcare and Family Care Leave Act (育児・介護休業法), a parent — mother or father — has the right to take childcare leave, and a valid request cannot simply be refused by the employer.

For fathers specifically, there are now two stacked options:

• Post-birth paternity leave (産後パパ育休 / 出生時育児休業), created in October 2022: up to 4 weeks within the 8 weeks after the birth, and you can split it into two blocks.
• Regular childcare leave (育児休業), which can also be split into two and taken up to (broadly) the child's first birthday, extendable in some cases.

So a father can take leave right at the birth, go back to work, and take more later — the system is built for flexibility, not a single all-or-nothing block.

Can your employer punish you for taking it?

No — the law forbids it, and companies have been held liable for trying. The Childcare and Family Care Leave Act prohibits disadvantageous treatment (dismissal, demotion, denied raises, punitive transfers) because an employee took childcare leave, and it requires employers to prevent "paternity harassment" (パタハラ).

This isn't theoretical:

• In the いわくら病院 (Inamonkai) case, a male employee who took childcare leave was then denied a pay raise and barred from a promotion exam. The court ruled this violated the Childcare and Family Care Leave Act and ordered the employer to pay damages.
• In the widely reported Asics case, a father who took childcare leave was moved to a subsidiary and low-importance work on his return, and sued for damages — a public example of paternity-leave retaliation being challenged in court.
• The Kaneka episode (2019), where a father was ordered a distant transfer just days after returning from leave, blew up into a national controversy on social media — not a court ruling, but a reminder that these disputes are now very public, and reputationally costly for employers.

If you face pressure, retaliation for taking childcare leave is against the law — document it and consult your labour bureau (労働局) or a lawyer.

How much do you actually get paid?

Paternity leave is paid, through employment insurance:

• 67% of salary for the first 180 days, then 50%.
• Since April 2025, if both parents each take at least 14 days, a top-up brings it to ~80% of gross ≈ 100% of your normal take-home for up to 28 days (the benefit is tax-free and premiums are waived).

That 2025 change was designed specifically to get fathers to take leave — the near-100% window only unlocks if both of you do. The full breakdown, caps, and eligibility are in how much you get paid on parental leave.

Why should dads actually take it?

Beyond wanting to — three concrete reasons the moment is now:

• The money rewards it. The both-parents top-up means the first weeks can cost your household almost nothing.
• The pressure on employers is real and rising. From 2025, companies with over 300 employees must publicly disclose their male childcare-leave uptake (and those over 100 must set and publish a target). Taking leave is increasingly normal and expected, not a favour.
• It's a one-time window. The newborn weeks don't come back — and shared leave is one of the strongest predictors of a more equal division of parenting later.

Uptake among fathers is still well below mothers', but it's climbing fast, and the law and the money are firmly on your side.

How do you request it?

The mechanics are straightforward:

• Notify your employer in advance — for post-birth paternity leave the standard deadline is about 2 weeks before it starts (shorter than the one month for regular childcare leave), and you can withdraw the request before it begins if your plans change.
• You can split the leave, so you don't have to choose between being there at the birth and later.
• The benefit is claimed through employment insurance (your employer usually files it), so confirm the paperwork with HR — or Hello Work if you're unsure.

How this fits your plan

For a couple, a father taking leave isn't just fair — with the 2025 top-up it's close to cost-neutral in the early weeks, and it reshapes how you share the year ahead.

Can my company punish me for taking paternity leave?

No — the law prohibits disadvantageous treatment (dismissal, demotion, denied raises, punitive transfers) for taking childcare leave, and requires employers to prevent paternity harassment. Courts have ordered employers to pay damages for penalising fathers who took leave.

Yes, through employment insurance: 67% of salary for the first 180 days, then 50%. Since April 2025, if both parents each take at least 14 days, a top-up brings it to roughly 100% of take-home for up to 28 days.

How long can a father take off?

Up to 4 weeks of post-birth paternity leave within the first 8 weeks (splittable), plus regular childcare leave up to around the child's first birthday (extendable in some cases and also splittable). You can combine and stagger them.

What is patahara (パタハラ)?

Paternity harassment — disadvantageous treatment or pressure directed at a father for taking or seeking childcare leave. It's unlawful; employers are legally required to prevent it, and affected fathers have won damages in court.
