Reduced-hours work means shortening contractual working hours. Childcare arrangements, family-care measures, and employer-designed short-time positions have different conditions. This guide focuses on childcare arrangements for employees of private-sector employers in Japan.
For finding a new role, see remote jobs with shorter hours or fewer days. Here, the focus is checking an arrangement with your current employer.
The statutory childcare arrangement generally concerns children under three
Employers must provide a reduced-hours arrangement including, in principle, a six-hour contractual working day for eligible employees raising a child under three. Eligible fathers can use it as well as mothers.
Check exclusions such as daily-hired workers, people whose contractual day is already six hours or less, and periods actually spent on childcare leave. Being labelled part-time or fixed-term does not automatically exclude someone.
A labour-management agreement can exclude certain employees, including those employed for less than a year, those working two contractual days a week or less, and those in work where a reduced-hours arrangement is difficult because of its nature or organisation. Alternative measures are required for the difficult-work exclusion. If told that a department is too busy, ask HR which rule, agreement, and alternative apply.
Separate three age-related questions
Arrangement | Child's age or condition | Important distinction |
|---|---|---|
Statutory childcare reduced hours | Generally under three | An employer may offer a longer period |
Childcare reduced-hours employment benefit | Raising a child under two and other conditions | The benefit and working arrangement do not have identical durations |
Flexible-working measures | From three until starting elementary school | Reduced hours are not necessarily an option at every employer |
Since October 2025, employers must select at least two of five measures for the latter age group: changing starting times, telework, childcare facilities or related arrangements, childcare-work compatibility support leave, and reduced hours. Employees choose one of the measures their employer provides. Before the child turns three, check the employer's selected measures and any extended reduced-hours policy.
Childcare time and exemption from extra work are separate
Under the Labour Standards Act, a woman raising a child under one can request childcare time twice a day, each lasting at least 30 minutes. This differs from the reduced-hours arrangement; check combined use if eligible and how the employer treats pay.
Shortening contractual hours and requesting a restriction on work beyond those hours are also separate procedures. Agree on finishing time, meetings, handovers, and necessary applications so that a shorter day does not routinely extend. For family-care absences, see family-care leave.
Check basic pay, allowances, and bonuses separately
There is no universal requirement to maintain normal wages for all unworked hours during reduced-hours work. Nor does every pay item necessarily fall by the same proportion. Compare the pay rules with the written arrangement.
For example, if contractual daily hours fall from eight to six and the employer's rule proportionately adjusts ¥300,000 basic monthly pay, the calculation is ¥300,000 × 6 ÷ 8 = ¥225,000. This is basic pay, not take-home income. It does not automatically apply the same ratio to fixed allowances, commuting costs, bonuses, tax, or social insurance.
- Which pay items change, using which hours or days?
- How are bonus periods, assessment, and targets adjusted?
- Who can estimate deductions and resulting take-home pay?
- What application and effective month apply when returning to longer hours?
The benefit is not 10% of the lost wages
Eligible employment-insurance members shortening contractual weekly hours to care for a child under two may receive the childcare reduced-hours employment benefit. Qualification includes starting continuously after qualifying childcare leave for the same child or, otherwise, generally having 12 qualifying months of wage-payment history in the preceding two years, with detailed conditions.
The rate depends on wages paid after shortening relative to the starting monthly wage amount. At 90% or less, the benefit is generally 10% of wages paid. Above 90% but below 100%, the rate is adjusted; at 100% or more, no benefit is paid. Payment limits and other adjustments also apply.
For example, with a ¥300,000 starting monthly wage amount and ¥225,000 wages in the relevant month, meeting the other payment conditions and with no payment-limit or other adjustment, the benefit is ¥22,500. It is not 10% of the ¥75,000 reduction. Benefit payments may arrive separately from payroll; check applications with the employer and Hello Work.
Align the application with the workload
- Identify the child's age and desired start and end dates.
- Check eligibility, application timing, and documents in the employment rules.
- Specify starting, finishing, and break times alongside childcare collection.
- Adjust duties, meetings, deadlines, handovers, and assessment targets.
- Obtain a pay estimate and check benefit, extension, and ending procedures.
For example: “I would like to discuss childcare reduced hours from [month], with six contractual working hours and a [time] finish. Could we check eligibility, the application deadline, pay calculation, and workload adjustments?”
For nursery applications, also check the employment certificate guide. Establish who takes over at finishing time rather than merely compressing unchanged duties into a shorter day.
