Foreign companies hiring their first employee in Japan through an Employer of Record (EOR) tend to treat paid annual leave (年次有給休暇) as a minor HR line item, something the EOR provider tracks in the background while the client focuses on payroll and visas. Two aspects of Japan's paid leave framework routinely surprise employers who assume this: the entitlement is not a policy an employer designs, it is a statutory accrual mechanism tied to tenure and attendance under the Labor Standards Act (労働基準法); and since a 2019 reform, granting the leave is not enough. Employers are legally required to ensure employees actually use a minimum amount of it each year, and failing to do so is a compliance failure that exposes the employer, not the employee, to consequences. This article separates what accrues automatically, what the 2019 usage-mandate reform actually requires, what an EOR provider administers operationally, and where the underlying obligation stays with the client regardless of the employment structure.
Paid Annual Leave (年次有給休暇) Is an Accrual Mechanism, Not a Policy
Under the Labor Standards Act, paid annual leave is not a benefit an employer chooses to offer at a chosen level. It is a statutory entitlement that accrues automatically once an employee has completed a qualifying period of continuous employment and has maintained a minimum attendance rate during that period. Two variables drive the calculation, and both matter operationally:
(a) Tenure. The entitlement begins after an initial qualifying period of continuous service and then increases with each additional year of continuous employment, following a fixed statutory scale up to a defined maximum. The exact number of days at each tenure milestone is a specific statutory figure that we do not restate here without a same-turn verification pass against the current text of the Labor Standards Act or Ministry of Health, Labour and Welfare (厚生労働省) guidance; treat the mechanism, tenure-linked scaling toward a statutory cap, as the framework, and confirm the current day-count table before setting policy for a specific hire.
(b) Attendance rate. Accrual in each subsequent period is conditioned on the employee having maintained a minimum attendance rate during the prior qualifying period. An employee who falls below that threshold in a given period does not accrue the incremental leave that period would otherwise have produced, even though their underlying tenure has continued to run.
The structural point foreign employers most often miss: this is not a benefit an employer can size up or down by contract. An employment contract (雇用契約書) or work rules (就業規則) that purports to grant less leave than the statutory schedule produces, or that conditions accrual on terms stricter than the statute allows, does not lower the employer's obligation. The statutory minimum applies regardless of what the contract says, and it applies identically whether the employee is engaged directly by a Japan entity or through an EOR.
The 2019 Reform: Granting Leave Is Not the Same as Ensuring It Is Used
Before the reform, Japan's paid leave problem was not a lack of statutory entitlement, it was a lack of usage. Employees frequently left the bulk of their entitlement unused, for reasons ranging from workplace culture to a perceived obligation not to inconvenience colleagues. The Labor Standards Act reform, effective from 2019, addressed this directly by shifting part of the obligation from the employee's initiative to the employer's affirmative duty.
Under the reform, an employer must ensure that any employee entitled to ten or more days of paid annual leave in a given year actually takes at least five of those days within that year. This is a genuinely different obligation from the pre-reform framework, where the employer's duty was largely limited to granting leave when the employee requested it and not obstructing that request. Now the employer carries an affirmative monitoring and, where necessary, scheduling obligation:
(a) The employer must track, for every employee entitled to ten or more days, how many days of leave that employee has actually taken during the leave year, not merely how many days remain unused in the balance.
(b) Where an employee is on track to fall short of the five-day minimum as the leave year progresses, the employer must take action to ensure the shortfall is closed, which in practice means designating specific leave dates for the employee (計画的付与, planned annual leave) if the employee has not taken sufficient leave on their own initiative.
(c) An employer that fails to meet this obligation for an eligible employee is in breach of the Labor Standards Act, and the exposure runs to the employer, not to a manager's individual judgment call. Employers face potential fines for non-compliance, assessed per affected employee, though we do not state a specific fine amount here; confirm current enforcement figures against Ministry of Health, Labour and Welfare guidance or a qualified labor advisor before relying on any number circulating informally.
The practical shift is this: before 2019, an employer who simply never said no to a leave request was largely compliant. After 2019, an employer whose employees are quietly not using their leave, for whatever cultural or workload reason, is exposed even though no employee ever complained and no request was ever denied.
What an EOR Provider Actually Administers
Under an EOR structure, the EOR entity is the legal employer of record and carries the compliance exposure described above directly. Its operational role on paid annual leave typically covers the following.
Leave grant timing tied to hire date. The qualifying period and the subsequent accrual dates run from the individual employee's hire date, not from a fixed calendar date shared across the workforce, unless the employer has adopted a uniform grant date (基準日) scheme across its EOR-employed staff. The EOR provider calculates and applies the correct grant date and day count for each employee individually as part of standard payroll and HR administration.
Balance tracking. The EOR provider maintains the running leave balance for each employee: days granted, days used, days carried forward, and days that will expire under the statutory carry-forward limit, so that both the client and the employee have an accurate, current figure rather than an estimate reconstructed after the fact.
Mandatory five-day usage monitoring. This is the part of the EOR's role that maps directly onto the 2019 reform. Because the EOR is the entity legally exposed if an eligible employee does not reach the five-day minimum, the EOR provider tracks usage against that threshold through the leave year and flags employees at risk of falling short before the year closes, so that a corrective step, such as planned annual leave designation, can still be taken in time.
Leave request administration. Processing requests, updating the balance, and coordinating with the client on scheduling, while respecting that the employee's right to take earned leave when requested is itself a statutory right the employer (via the EOR) cannot simply decline.
What Stays a Genuine Client Obligation
Administering the mechanics is not the same as controlling the outcome, and this is the distinction clients frequently blur.
(a) The underlying obligation to make sure the five-day minimum is actually met sits with the employer relationship as a whole, not with the EOR's back office alone. If a client company directs an employee's workload so heavily that the employee cannot realistically take leave, no amount of EOR-side tracking changes the fact that the statutory obligation runs against the employer. The EOR flags the risk; closing the gap in practice, adjusting workload, approving requested dates, or agreeing to planned annual leave designation for the affected employee, requires the client's operational cooperation.
(b) The client cannot instruct the EOR to withhold or reduce the statutory entitlement. Requests to size leave policy down to match a foreign parent's preferred package, or to treat leave as something the employee "shouldn't need" given other benefits, are not requests an EOR can lawfully implement. The statutory floor is not negotiable by client instruction.
(c) Monitoring is not scheduling authority. The EOR provider can identify that an employee is at risk of falling short of the five-day minimum and can execute a planned annual leave designation once the client and employee reach an arrangement, but deciding how work is distributed so that leave-taking is actually feasible during the year is a day-to-day management decision that belongs to the client, since the client directs the employee's work under the EOR structure.
The "Unlimited PTO" and Home-Country Policy Misconception
A specific misconception recurs often enough to address directly: foreign employers, particularly those from markets where "unlimited PTO" or a flexible discretionary leave policy is standard, assume that offering something more generous on paper substitutes for compliance with Japan's statutory scheme. It does not, for two separate reasons.
First, an unlimited or discretionary leave policy does not satisfy the mandatory five-day usage requirement on its own. The 2019 reform obligation is not "make leave available"; it is "ensure the employee actually takes at least five days." A generous but undocumented, unmonitored policy where an employee could theoretically take unlimited leave but in practice takes very little does not meet the statutory test. Without tracking actual days used against the five-day threshold, an "unlimited PTO" policy can leave an employer just as exposed as a policy that formally grants only the statutory minimum, because the exposure is triggered by non-use, not by the generosity of the stated policy.
Second, a foreign parent's home-country leave policy has no legal force in Japan unless it is built into the Japan employment terms in a way that meets or exceeds the statutory Japan framework. A policy document written for a jurisdiction without a mandatory accrual-and-usage scheme does not override the Labor Standards Act simply because the parent company applies it globally. Any home-country policy imported into a Japan hire's terms has to be checked against, and layered on top of, the statutory minimum, not treated as a replacement for it. In practice, this usually means the Japan-specific terms of employment need to state the statutory accrual mechanism explicitly and track actual usage against the five-day minimum, regardless of what broader global policy language says about flexibility or unlimited leave.
Conclusion
Paid annual leave under a Japan EOR arrangement is not a background administrative task. It is a statutory accrual scheme tied to tenure and attendance, layered with an affirmative employer duty, since the 2019 reform, to ensure a minimum amount of it is actually used, not merely granted. An EOR provider administers the mechanics correctly: grant timing by hire date, balance tracking, and monitoring against the five-day usage threshold. What it cannot do is substitute for the client's operational cooperation in making leave-taking feasible, or accept an instruction to size the entitlement down to match a foreign policy that was never built for Japan's statutory framework. Employers hiring their first Japan employee should confirm with their EOR provider exactly how usage monitoring works and what happens, contractually and operationally, if an employee is on track to fall short of the mandatory minimum as the leave year closes.
