Childcare Shorter-Hours Benefit: How Much Per Month?

The conclusion: a quick table by monthly pay (before and after the change)

Sources: Ministry of Health, Labour and Welfare and Hello Work, "Childcare shorter-hours working benefit: content and application procedure" (version current as of 1 August 2026)[MHLW]; "The payment limits change from 1 August 2026"[MHLW]

The basic rule is "wage actually paid in each month of shorter-hours work × 10%". If your shorter-hours wage is 90% or less of what it was before, you get the full 10%; between more than 90% and less than 100%, the rate falls so that wage plus benefit does not exceed your wage before the change. In a month where your wage is the same as before or higher, the benefit is zero. The ceiling is 484,121 yen for wage and benefit combined in each month, and no benefit is paid in a month where it would come to 2,562 yen or less (both figures apply until 31 July 2027).

Who qualifies

• An employment insurance subscriber who is working reduced contractual hours in order to raise a child under the age of two. The shape of the reduction does not matter (six hours a day, four days a week, and so on). The premise is that your wage has fallen while you work shorter hours.
• Either you started shorter hours directly after parental leave covered by the parental leave benefit, or you have 12 months or more with 11 or more days counted as the basis for wage payment, within the two years before the shorter hours began.
• It runs until the day before the child's second birthday. Go back to work at age one and switch to shorter hours and you get up to a year of it; return eight weeks after the birth and it is about a year and ten months.
• Either parent can receive it, and if both work shorter hours, both receive it.

People who were already working shorter hours before 1 April 2025 also became eligible for the months from that date onwards. In a month where you receive the parental leave benefit or the family care leave benefit, the childcare shorter-hours working benefit is not paid for that month.

The real cost of shorter hours: if monthly pay falls by 60,000 yen, how much take-home pay do you lose?

"Shorter hours means 60,000 yen a month less" is a gross-pay statement, and take-home pay is a different story. When your wage falls under shorter hours, your social insurance premiums fall too (your standard monthly remuneration grade drops), and so do income tax and resident tax, and the 10% benefit sits on top of that.

Even with a 60,000 yen fall in gross pay, the gap in take-home terms narrows to a little over 20,000 yen. Over the year from the child's first to second birthday, a gross gap of 720,000 yen becomes a gap of about 280,000 yen in take-home pay plus benefit. Before you decide shorter hours are a bad deal and force yourself back to full time, compare these figures.

Seen the other way round, the benefit does not mean shorter hours leave your pension untouched. Make sure you also file the special rule below.

File the "special rule on standard monthly remuneration during a child-raising period" at the same time

When shorter hours push your standard monthly remuneration down, the employees' pension premiums you pay fall, but your future pension is also calculated on the reduced figure. The "deemed former standard monthly remuneration measure for child-raising periods" prevents that: while you are raising a child under three, the pension calculation alone uses the standard monthly remuneration you had before the shorter hours. You pay premiums on the reduced amount and your pension does not shrink, which is a special rule squarely in your favour.

You submit a "notification for the special rule on standard monthly remuneration during a child-raising period" to the pension office through your employer. It is a separate procedure from the childcare shorter-hours working benefit, and it does not apply unless you file it. Backdating only reaches the two years up to the month before you file, so once shorter hours begin, check with your employer early. Both parents can file.

How to apply: through your employer, every two months

1. Once shorter hours begin, your employer files a "confirmation of eligibility" and a "notification of the wage at the start of shorter hours" with Hello Work. Your "monthly wage at the start of shorter hours" is set from the wage of the six months before the change, and that figure is the basis for the 90% test and for the ceiling.
2. The first application must be made within four months of the first day of the month in which shorter hours began. It can be filed at the same time as the confirmation of eligibility.
3. After that, your employer applies every two months. The benefit months are calendar months, and documents proving the wage for each month (wage ledger, attendance record) are attached. Payment arrives about a week after the application. You can also apply yourself.
4. It ends with the month containing the day before the child's second birthday. A month in which you stop shorter hours and return to full time, or start parental leave or family care leave, is also outside the scheme.

The benefit is tax-free: it is not counted for income tax or resident tax, and it is not included in the calculation of social insurance premiums. You do not need to declare it in the year-end adjustment or a tax return. For how tax works during maternity and parental leave, see the year-end adjustment during maternity and parental leave.

From the parental leave benefit to the shorter-hours benefit

Employment insurance offers four benefits between the birth and the child's second birthday: the postnatal parental leave benefit (postnatal paternity leave, 67%), the parental leave benefit (67%, 50% from day 181), the postnatal leave support benefit (an extra 13% for the first 28 days when both parents take leave), and, after the return to work, the childcare shorter-hours working benefit (10%). Take parental leave until age one, come back on shorter hours and work until the child is two, and there is no gap in the benefits. For the whole picture, see the money you can receive for childbirth and childcare.

If you cut your hours so far that you fall below 20 hours a week, you can drop out of the requirements for social insurance and leave health insurance and employees' pension. That also unsettles the premise of the benefit itself (being an employment insurance subscriber), so treat 20 hours a week as the floor when you design your shorter hours. The membership requirements are set out in the 1.06 million yen and 1.3 million yen thresholds.

Frequently asked questions

Summary

• For people whose wages drop because they work shorter hours for a child under age 2, employment insurance adds 10% of the reduced-hours wage on top, every month.
• If a ¥300,000 monthly salary falls to ¥240,000, the benefit is ¥24,000 a month, tax-free, until the day before the child's second birthday.
• The benefit tapers once wages exceed 90% of the pre-reduction level. The cap combined with wages is ¥484,121 (revised August 2026).
• Because social insurance premiums and tax also fall, even a ¥60,000 drop in monthly pay leaves a gap of only about ¥23,000 a month between take-home pay plus benefit and the original pay.
• To keep pension benefits from shrinking, file a separate childcare-period standard remuneration special notification through your employer.
