After Your Baby Is Born in Japan: Admin & Allowances

Quick Answer: In the first weeks after a birth in Japan you register the baby (出生届 within 14 days), add them to your health insurance, and get their My Number — and if you're a foreign couple, you must also apply for the baby's Status of Residence at Immigration within 30 days, because a baby born to two foreign parents is not automatically Japanese. Then claim the ongoing money: the child allowance (児童手当) — ¥15,000/month for under-3s, ¥10,000 after, with no income limit — and your municipality's child medical subsidy (children's healthcare is often free or nearly free). Apply for the allowance within 15 days so you don't lose a month.

The cost and the leave benefits get the attention, but the newborn stage is really an admin sprint: a handful of forms in the first two weeks that switch on real, ongoing money. Miss the deadlines and you lose payments you were entitled to. This guide is the checklist — what to file, where, and by when — written for foreign parents in Japan.

This is educational information, not legal or tax advice. Procedures and amounts vary by municipality and change over time — confirm with your city office (市区町村役場) or a qualified professional.

What do you need to do in the first two weeks?

Three registrations, all at (or through) your city office — ideally in one visit:

If you handled your own first-year set-up, this is the same muscle — just for a new, very small resident.

If you're a foreign couple: the baby's residence status and nationality

This is the step foreign parents most often miss, and it carries the biggest consequences — so treat it as a hard deadline, not an afterthought.

Japan grants nationality by descent, not by birthplace. A baby born in Japan to two foreign parents does not become Japanese — the baby takes the parents' nationality. (If one parent is Japanese, the baby can be Japanese, with a nationality choice required later in life.)

So for a foreign baby who will stay in Japan, two more things are on the clock:

Immigration cases can get complicated (mixed-nationality couples, permanent residents, specific visa types). For anything non-standard, a licensed immigration specialist (行政書士) is worth the fee.

How does the child allowance (児童手当) work — and how do you claim it?

The child allowance (児童手当) is the main ongoing payment, and since October 2024 there's no income limit — every household gets it. The amounts:

It's paid six times a year (even months), and it is not automatic — you must apply. Crucially, use the "15-day rule": if you apply within 15 days of the birth, the allowance is paid from the month of the birth, even if the paperwork lands the following month. Apply late and you simply lose those months — so file it at the same time as the birth registration.

These amounts are national — the same everywhere. The child allowance is set by national law, so it doesn't change by prefecture or city: ¥15,000 / ¥10,000 / ¥30,000 is identical in Tokyo, Osaka, or rural Hokkaido. What does vary locally is the child medical subsidy (below) and any extra child-rearing support your specific municipality chooses to add — some cities offer their own birth grants or bonuses on top, so it's worth checking your ward's own programmes.

Does your child get free healthcare in Japan?

Largely, yes — and this is the benefit foreign parents most often don't realise. On top of national health insurance (which already covers most of the cost), your municipality runs a child medical subsidy (子ども医療費助成) that covers much or all of the remaining out-of-pocket share.

Check your own city's rules, because this is one of the more generous — and most local — supports you'll use for years.

Can you claim birth costs back on your tax?

Often, yes. Childbirth and pregnancy costs count toward the year-end medical expense deduction (医療費控除) — but you must subtract the childbirth lump-sum and any other benefits you received first, because those were reimbursed, not spent. If your remaining out-of-pocket medical costs for the household still cross the threshold, the deduction lowers your income and resident tax.

What ongoing costs should you plan for?

The big one after the newborn stage is childcare. Licensed daycare (認可保育園) fees are income-based and often subsidised, and there's broader free/low-cost early-education support — but availability and cost vary a lot by area, so it's worth researching your ward early. This is where a baby genuinely reshapes a household budget, far more than the birth itself.

How this fits your plan

The newborn admin isn't just paperwork — it switches on payments (allowance, medical subsidy, tax relief) that add up over years, and it's easy to leave money on the table by missing a deadline. Once it's done, model how the new costs and the child allowance shift your household timeline with the free PlanTogetherFI calculator, and see the income side during leave in how much you get paid on parental leave.

Frequently Asked Questions

What do you have to do after a baby is born in Japan?

Within 14 days, register the birth (出生届) at your city office, add the baby to your health insurance, and obtain their My Number. Foreign parents must also apply for the baby's Status of Residence at Immigration within 30 days. Then apply for the child allowance (ideally within 15 days of birth) and your municipality's child medical subsidy.

Does a baby born in Japan get Japanese citizenship?

Not automatically. Japan grants nationality by descent, so a baby born to two foreign parents takes the parents' nationality, not Japanese. If one parent is Japanese, the baby can be Japanese (with a nationality choice required later in life). Foreign babies need a Status of Residence from Immigration.

What is the deadline for the baby's residence status?

Within 30 days of birth, at a Regional Immigration Services Bureau, if the baby will stay in Japan beyond 60 days. It's free and generally mirrors the parents' status — and you may need to apply before the passport is issued. Missing it can leave the baby out of status, so file it right after the birth registration.

How much is the child allowance in Japan?

¥15,000/month for a child under 3, ¥10,000/month from age 3 through high-school age, and ¥30,000/month for a third child onward. Since October 2024 there's no income limit, so every household qualifies. It's paid six times a year and must be applied for.

Do foreigners get the child allowance in Japan?

Yes. It depends on being a resident raising the child in Japan, not on nationality. Register your address and the birth, then apply at your city office — the same as any resident household.

Is children's medical care free in Japan?

In most municipalities it's free or nearly free up to a certain age, through a local child medical subsidy on top of national health insurance. The exact age and any small fees vary by area, so check your own city's programme.

When should I apply for the child allowance?

At the same time as the birth registration, and within 15 days of the birth. Under the "15-day rule," applying within that window means you receive the allowance from the birth month; applying later means you lose the months before your application.
