Employer of Record (EOR) is one of the most effective tools for testing a Japan market. It lets a foreign company hire employees in Japan in weeks rather than months, without incorporating a local entity, and without navigating social insurance registration, payroll setup, or labor bureau filings from scratch. For a first or second hire during an exploratory phase, EOR is often the correct decision. The problem is that many companies reach five, eight, or twelve employees still running on EOR, with no plan to transition. At that scale, EOR has moved from a strategic enabler to an operational and commercial liability. This guide explains the specific triggers that signal it is time to incorporate a Kabushiki Kaisha (株式会社, KK) or Godo Kaisha (合同会社, GK), how to transfer employees correctly under Japanese labor law, and what compliance obligations stay with the company regardless of which employer structure it uses.
EOR Is an Entry Mechanism, Not a Permanent Operating Model
The architecture of EOR reflects this scope. The EOR provider is the legal employer on record in Japan. It signs the employment contracts, handles social insurance enrollment, runs payroll, and files the necessary labor bureau notifications. Your company directs the work and pays the EOR a monthly fee that bundles the employee's gross salary, employer social insurance contributions, and the EOR service margin.
This works well at low headcount because the fixed costs of incorporation, including registered office, annual tax filing, accounting, corporate bank account maintenance, and representative director obligations, can easily exceed the EOR premium when you have one or two people on the ground. As headcount grows, the per-head EOR fee compounds, and those same fixed incorporation costs become economical by comparison. The math typically shifts somewhere between five and ten employees, though the exact crossover depends on salary levels and the scope of your Japan operation.
Beyond cost, EOR has structural limitations that make it unsuitable as a long-term arrangement for a company with genuine Japan ambitions. A Japan operation of meaningful scale should be able to hold licenses in its own name, contract directly with Japanese counterparties, and sponsor visas for its own leadership. EOR forecloses all three.
The Specific Triggers for Transition
Team Size Crosses the Cost Threshold
At small headcount, EOR's per-head cost structure is justified: you are paying for speed, simplicity, and the provider's compliance infrastructure. At higher headcount, that same structure becomes expensive relative to running your own entity. A KK or GK with five or more employees typically costs less per employee on a fully-loaded basis than continued EOR, once you account for the amortization of fixed entity costs across a larger base.
If your Japan team has reached five employees and is growing, a cost comparison against direct employment is worth running before committing to another EOR contract cycle. The comparison should include: incorporation costs (one-time), annual accounting and tax filing, registered office fee, corporate bank account fees, and a part-time HR or payroll administration cost. Set that against the cumulative EOR margin across your projected headcount for the next two years.
Your Business Activity Requires a Japan-Registered License Holder
Certain regulated sectors require the operating entity itself to hold a Japanese license or registration. Financial services, medical device sales, food manufacturing, travel agency business, and several others fall into this category. The license is issued to the licensed entity; it cannot be held by an EOR provider on your behalf. If your Japan business model requires a license, incorporating your own entity is not optional.
This is one of the most common situations where companies discover, mid-operation, that their EOR arrangement has become a structural barrier. The EOR can employ your sales team; it cannot be the licensed financial instruments business operator or the registered medical device marketing authorization holder. That entity must be yours.
You Want to Sponsor a Business Manager Visa
The Business Manager Visa (経営管理ビザ) allows a foreign national to reside in Japan as a company executive or manager. It is the standard pathway for a founder or regional director who needs to be physically based in Japan. The visa requires a sponsoring entity that is incorporated in Japan, has demonstrated paid-in capital of at least 500,000 yen, and has a physical Japan office address (not a pure virtual address, though a shared office with a dedicated space often qualifies).
An EOR arrangement cannot sponsor this visa. The EOR provider is the employer of record; you are a client of the EOR. That relationship does not give the foreign executive a path to the Business Manager Visa under your company's name. If your Japan strategy involves having a founder or senior executive resident in Japan on a business manager status, you need your own entity before you can file that visa application.
Enterprise Buyers and Government Clients Require a Japan-Registered Counterparty
In Japan's corporate procurement culture, particularly among large enterprises and government-related entities, the identity of the counterparty on a contract matters. Buyers conduct registry checks, look at the signing entity's registration, and in some cases require a Japan-registered business number on invoices. When your contracts show the EOR provider's name as the employer, and your invoices come from an overseas entity, some buyers will hesitate or decline entirely.
This is not universal: many mid-market Japanese companies transact comfortably with foreign entities. But in sectors where government contracting, enterprise software procurement, or regulated financial services are part of your target market, the absence of a Japan-registered entity is a commercial disadvantage that accumulates over time.
Your Japan Revenue Justifies the Overhead
Entity compliance costs in Japan are real but predictable. Annual accounting and tax filing for a small entity typically runs 500,000 to 1,000,000 yen depending on complexity. Registered office costs run 100,000 to 200,000 yen per year for a shared office arrangement. Corporate bank account maintenance is minimal. Total annual overhead for a lean KK or GK is manageable at revenue levels that are already justifying a multi-person Japan team.
If your Japan operation is generating meaningful revenue and carrying several employees, the entity compliance cost is a rounding error in the P&L. The EOR margin, by contrast, is a line item that grows with headcount. Once Japan revenue is established, the commercial case for direct employment under your own entity is straightforward.
How to Transfer Employees from EOR to Your New Entity
This is the step that companies most frequently handle incorrectly. The instinct is to treat the transfer as simple: terminate the employees at the EOR level and re-hire them into the new entity on the same or better terms. The problem is that under the Labor Contract Act (労働契約法), terminating an employee in order to sidestep accumulated rights, including seniority and the dismissal protections that attach to a continuous employment relationship, is not a legitimate basis for termination. Article 10 of the Labor Contract Act also governs changes to working conditions and requires that any changes either be agreed with the employee or, in limited circumstances, pass a reasonableness test.
The correct approach to an EOR-to-entity transfer involves several steps.
First, the new entity must be incorporated and must complete its own social insurance registration with the applicable pension office and health insurance association before it can enroll employees. This registration takes time; build it into your transition timeline.
Second, each employee must be provided with, and must consent to, a new written employment contract with the new entity as employer. The contract should preserve, or improve upon, the terms that were in place under the EOR arrangement: job description, salary, working hours, and annual leave entitlement. You cannot present the transfer as a fait accompli; it requires the employee's affirmative agreement.
Third, the transfer should be framed as a consensual employer change rather than a termination and re-hire. This matters for two reasons: it preserves the continuity of the employment relationship for the employee's benefit, and it avoids any argument that the "termination" was pretextual. Where possible, coordinate with your EOR provider on the handover mechanics, including the final payroll run and the timing of social insurance unenrollment at the EOR's end and re-enrollment at the new entity's end.
Fourth, if any employees have accumulated severance entitlement under the terms of the original EOR contract, or under a retirement allowance scheme that was in place, those entitlements must be addressed before or at the point of transfer. Do not assume that a new contract resets the clock on accumulated rights without legal review.
The transition is manageable with proper planning. The companies that run into problems are those that attempt it without adequate notice periods, without employment contracts for the new entity ready before the transition date, or without completing the new entity's social insurance registration in advance.
The Parallel for Import Structures: IOR and ACP
Companies that have been importing into Japan via Aplash as Importer of Record (IOR), or via an Attorney for Customs Procedures (税関事務管理人, ACP) arrangement under Article 95 of the Customs Act (関税法), face a similar graduation decision once they incorporate a Japan entity.
Once your KK or GK is incorporated and registered, it can appear directly on the import declaration (輸入申告) as the Japan-resident importer. Direct import eliminates the need for a third-party IOR arrangement for standard goods and allows the entity to register as a Qualified Invoice Issuer (適格請求書発行事業者) and recover consumption tax (消費税) directly. ACP also becomes unnecessary once you have a Japan address and legal presence, since ACP exists specifically to give non-resident importers a Japan-based procedural agent before customs.
The IOR and ACP structures remain available for specific situations, including controlled goods, shipments requiring specialized compliance support, or cases where the entity prefers to outsource the importer liability. But the base case for an incorporated entity is direct import in its own name.
What Does Not Change After Transition
Incorporating a KK or GK does not alter Japan's labor law obligations. The Labor Standards Act (労働基準法) applies to every employer in Japan regardless of the employer's corporate form. The rules on dismissal, paid leave (10 days minimum annual leave accruing after six months of continuous employment), working hours, and social insurance contributions are identical whether the employer is an EOR provider or your own entity.
This is the source of a common misconception among companies transitioning out of EOR. EOR managed those obligations on your behalf; it did not shield your employees from them or create a softer set of rules. When you become the direct employer, you inherit the full legal framework that applied during the EOR period, including the dismissal protections that attach to employees with over one year of continuous service. Dismissal without objective and reasonable cause remains unlawful under the Labor Contract Act regardless of corporate structure.
The Common Mistake at Transition
The most frequent error is incorporating the entity first and planning the employee transfer later. Companies focused on the incorporation timeline often complete the registry filing, open a bank account, and start using the entity for commercial contracts, while leaving employees on the EOR for another quarter or two "until we sort out the transfer."
This creates a period where the entity exists but has no employees, and the EOR is running parallel at ongoing cost. More seriously, it defers the social insurance registration of the new entity, which must be completed before the first employee can be enrolled. When the transfer finally happens on a rushed timeline, employment contracts for the new entity are often not ready, the payroll setup is incomplete, or the social insurance handover creates gaps in coverage. Employees notice these gaps; they affect trust.
The correct sequence is: decide to incorporate, complete incorporation, immediately initiate social insurance registration for the new entity, prepare employment contracts for each transferring employee, agree a transfer date with the EOR provider, and execute the transition on a date when all three elements (registered entity, social insurance enrollment, signed new contracts) are in place simultaneously.
Decision Framework: EOR vs. Own Entity
The following factors anchor the decision.
(a) Headcount: One to four employees, exploratory phase, no licensed activity: EOR is appropriate. Five or more employees, or active sales revenue: run the cost comparison.
(b) Business activity: Any licensed or regulated activity including financial services, medical, food manufacturing, or travel: own entity required. Unlicensed services or product sales below regulated thresholds: EOR remains viable.
(c) Brand and counterparty requirements: Large enterprise or government procurement targets: own entity strongly preferred. Mid-market or startup-to-startup: EOR less likely to create friction.
(d) Founder or executive visa: Business Manager Visa required for any director or founder: own entity required before visa application.
(e) Import structure: Active import operations: own entity enables direct import and consumption tax recovery, reducing the ongoing need for IOR or ACP.
(f) Long-term intent: If Japan is a core market for the next five or more years, the entity provides the structural foundation for licensing, contracting, banking, and hiring that EOR cannot replicate. EOR makes sense as a bridge; it is not a destination.
