Foreign companies researching how to hire in Japan without an entity frequently arrive with a term borrowed from the US market: PEO, or Professional Employer Organization. It is a reasonable place to start, since PEO is the dominant term for outsourced employment in the United States. The problem is that Japan does not have a PEO market in the sense the term is used elsewhere, and vendors who advertise "PEO services" in Japan are, in nearly every case, actually describing an Employer of Record (EOR) arrangement, or in some cases describing something closer to licensed staffing under a completely different legal framework. Understanding why the terms diverge, and what actually exists under Japanese law, prevents a foreign company from scoping a hiring project around a structure that has no real Japan equivalent.
What a PEO Actually Is, and Why It Needs a Local Entity
In the United States, a PEO operates on a co-employment model. The client company and the PEO are both, in a specific legal sense, employers of the same worker: the PEO handles payroll, benefits administration, and certain statutory compliance obligations, while the client company retains day-to-day direction of the work and, critically, still has its own legal entity in the jurisdiction where the worker is based. Co-employment is a US legal construct built around specific state and federal frameworks, and it presupposes that the client already has a registered business presence to share employer status with the PEO. A PEO is not, by design, a solution for a company with no local legal entity at all. It is a way for a company that already has a US entity to outsource HR administration.
Japan has no equivalent co-employment framework. There is no Japanese legal mechanism under which a foreign company without a Japan entity and a Japan-based service provider jointly hold employer status over the same worker in the way US co-employment operates. This is not a gap in the market; it is a structural feature of Japanese labor law. Employer status in Japan is not something Japanese law allows to be split or shared informally between two parties for administrative convenience.
What Actually Exists: EOR and Licensed Labor Dispatch
Two structures are available to a foreign company that wants to place a worker in Japan without incorporating its own entity, and they are legally distinct from each other and from a US-style PEO.
Employer of Record (EOR). Under an EOR arrangement, a Japan-registered entity, such as Aplash, becomes the sole legal employer (雇用主) of the worker. The EOR signs the employment contract, runs Japanese yen payroll, enrolls the employee in mandatory social insurance under the Employees' Health Insurance Act (健康保険法) and the Employees' Pension Insurance Act (厚生年金保険法), and withholds and remits income tax. The foreign company directs the worker's day-to-day tasks and deliverables through a separate commercial services agreement with the EOR, but it is not itself an employer under Japanese law. This is a single-employer structure, not co-employment, and it is the practical answer to "how do we hire in Japan without an entity."
Licensed labor dispatch (労働者派遣, under the Worker Dispatch Act, 労働者派遣法). This is a genuinely different legal category, sometimes mistaken for PEO because it also involves a third party standing between the worker and the company directing their work. Under labor dispatch, a licensed dispatch agency employs the worker and assigns them to a client company, which directs the work on-site. Dispatch is subject to specific statutory limits, including a general rule that a dispatched worker cannot remain assigned to the same organizational unit at the same client for more than three years, after which the client must either hire the worker directly or end the placement. Dispatch also requires the dispatch agency to hold a specific government license, and it carries its own set of restrictions on which types of work can be staffed this way. Labor dispatch is designed for flexible or temporary staffing arrangements, not as a general-purpose entity-free hiring solution, and it operates under materially different rules than EOR on duration, licensing, and who bears statutory employer obligations.
Why the Distinction Matters Commercially
(a) Liability allocation is different. Under EOR, the EOR provider carries full statutory employer liability and compliance responsibility. There is no shared or ambiguous liability the way a US PEO's co-employment model can create. A foreign company evaluating "PEO" providers in Japan should confirm which of these two structures is actually being offered, because the liability picture is not the same.
(b) Duration and headcount planning differ. EOR has no statutory time limit on how long an employee can be engaged this way, though it becomes economically less efficient than direct entity employment at higher headcounts. Labor dispatch has a hard statutory ceiling on assignment duration at the same organizational unit, which makes it unsuitable for a role a company expects to be permanent from the outset.
(c) The type of work matters. Labor dispatch has restrictions on the categories of work that can be staffed under the dispatch framework. EOR does not carry the same category restrictions in the same way, since the worker is directly employed by the EOR rather than assigned under a dispatch license.
(d) Vendor terminology is not a reliable guide. Because "PEO" is a familiar and search-friendly term globally, some providers use it in Japan marketing materials to describe what is functionally an EOR arrangement, and occasionally to describe a dispatch arrangement without clearly flagging the difference. A foreign company should ask directly which Japanese legal structure a "PEO" provider is actually proposing, rather than assuming the term maps cleanly onto what it means elsewhere.
Which One Does a Foreign Company Actually Need
For the vast majority of foreign companies entering Japan and hiring their first one to a handful of employees, without a Japan entity and without a bounded, temporary staffing need, EOR is the applicable structure, not a US-style PEO and not licensed labor dispatch. EOR fits a company that wants a direct, ongoing employment relationship managed by a Japan-resident employer, with no statutory time limit and no work-category restriction.
Labor dispatch becomes the relevant structure only in a narrower case: where the intended arrangement is genuinely temporary or project-bound staffing, where the categories of work involved are compatible with the dispatch framework, and where the company understands and accepts the duration ceiling from the outset. It is not a substitute for EOR when the intent is a standard, ongoing employment relationship.
A true co-employment PEO, in the US sense, is not an available option in Japan under either structure, because Japanese law does not recognize a split employer status between a foreign company with no Japan presence and a Japan-based service provider. Any proposal describing itself as "PEO" for Japan should be examined to determine which of the two real structures, EOR or licensed dispatch, it is actually delivering.
