Foreign companies entering Japan almost always frame the market entry question the same way: do we need a Japan entity? That framing is not wrong, but it puts the answer before the analysis. The more useful prior question is: what exactly does this company need to do in Japan, and which of those activities actually require a Japan entity? For many companies, the answer splits cleanly into two independent tracks. One track involves getting physical goods into Japan compliantly. The other involves placing a person in Japan to execute commercially. A Japan entity solves both, but it is the highest-cost, highest-overhead solution, and it is typically the right answer only after a company has validated Japan as a market and is scaling a local operation. The Importer of Record (IOR) plus Employer of Record (EOR) combination is the structure that lets a company run a real Japan commercial operation, with physical goods and a local employee, before making that commitment.
What Each Service Covers
Importer of Record (IOR)
The Importer of Record is the legally named party on Japan's import declaration (輸入申告, the customs declaration filed under the Customs Act (関税法)). The IOR holds genuine disposition rights (処分権限) over the goods at the time of import, pays customs duties and import consumption tax, and is responsible under the Customs Act for the accuracy of the declaration. Under Japanese customs law, the IOR must be the entity that actually owns or has legal rights over the goods at the point of import. A party that appears on the declaration without underlying commercial substance creates a false declaration risk.
When a foreign company has no Japan entity, two structures allow compliant import. Under a standard IOR arrangement, a Japan-resident entity such as Aplash acts as the buyer of the goods from the overseas seller, files the import declaration in its own name, and re-sells the cleared goods to the Japan buyer. Under an Attorney for Customs Procedures (ACP, 税関事務管理人) appointment, the overseas manufacturer itself is the named importer on the declaration, and a Japan-resident party serves as its procedural representative before Japan Customs pursuant to Article 95 of the Customs Act (関税法). These two structures are legally distinct: in IOR, Aplash takes title; in ACP, the overseas company is the importer. They are not alternatives to be selected based on preference; the applicable structure depends on who holds title, who has disposition rights, and who is the beneficial importer. Either way, the goods enter Japan compliantly without a Japan entity.
Employer of Record (EOR)
Under an Employer of Record arrangement, a Japan-registered entity becomes the legal employer (雇用主) of a candidate identified by the foreign company. The EOR entity signs the employment contract with the employee, runs payroll in Japanese yen, handles mandatory social insurance enrollment under the Employees' Health Insurance Act (健康保険法) and the Employees' Pension Insurance Act (厚生年金保険法), withholds and remits income tax, and bears all statutory employer-side obligations under Japanese law. The foreign company directs the employee's day-to-day work and defines deliverables through a separate commercial services agreement with the EOR. The EOR is the employer in the legal and administrative sense; the foreign company is the economic beneficiary of the employment relationship.
The EOR structure allows a foreign company to hire a Japan-resident employee within two to four weeks, without incorporating a Japan entity, without appointing a representative director, and without any of the annual statutory compliance obligations that come with a Japan company.
When You Need Both at the Same Time
The combined IOR plus EOR structure is not a theoretical edge case. It describes a specific and common commercial profile. Several situations fit it directly.
(a) Product-led market entry with a local commercial presence. The company wants to import and sell physical goods in Japan. It also wants a Japan-based employee to build distributor relationships, manage local accounts, or provide technical support. A Japan entity is not yet justified because the market is unvalidated or the transaction volume is insufficient to clear entity overhead costs. IOR handles goods flow; EOR handles the person.
(b) Hardware plus services model. Technology companies selling physical hardware into Japan (IOR for the device) alongside a Japan-based customer success or implementation function (EOR for the staff) need both tracks running simultaneously from the start of commercial operations.
(c) Distribution with key account management. The goods flow to a Japanese distributor under IOR, but the foreign company wants a Japan-based national accounts manager who actively manages that distributor relationship and the end-customer pipeline. The goods track and the people track are independent but commercially integrated.
(d) Pilot operations before the entity decision. A company running a Japan market test over 12 to 18 months, with goods and one or two people, while keeping the entity formation decision open until it has conversion rate data, unit economics, and a read on whether Japan is worth the permanent overhead. IOR handles goods; EOR handles the team; the entity decision is deferred until the data supports it.
What IOR and EOR Do Not Solve
Setting accurate expectations upfront prevents structural mistakes later.
(a) No Japan tax residency or corporate presence. This combined structure does not create a Japan-resident entity in the foreign company's name. The foreign company has no Japan corporate tax filing obligation under this structure, provided it has no permanent establishment (恒久的施設, PE) in Japan. Whether an EOR employee creates PE risk depends on the nature of that employee's activities. An employee who negotiates and concludes contracts in Japan on the foreign company's behalf may create PE under applicable tax treaty provisions. This is a tax analysis question, not a customs question, and it requires qualified tax counsel to assess based on the specific role and activities. The IOR plus EOR structure does not itself resolve PE exposure; that question must be assessed separately before the structure is implemented.
(b) No Japan company registration number or bank account. Some Japanese corporate procurement processes require a Japan-incorporated vendor. A customer who demands a Japan-registered counterparty with a Japanese company registration number (法人番号) for purchase order processing will not accept a foreign company operating under IOR plus EOR. If the end-customer relationship requires a Japan-incorporated vendor, entity formation is necessary regardless of import volume or headcount.
(c) No direct employment in the foreign company's name. The EOR employee's employer of record is the EOR provider. The foreign company's name does not appear on the employment contract. For roles where the employer brand is commercially significant to the candidate, or where the company's own entity identity needs to appear on the employment relationship, this is a real limitation. Some senior hires or regulated-role hires may require direct employment by a Japan entity.
How the Two Tracks Interact Operationally
The IOR arrangement handles goods flow. Shipments are planned and documented; the IOR provider or the manufacturer under an ACP appointment manages customs clearance; cleared goods flow to the Japan buyer, distributor, or warehouse. The EOR employee operates as the commercial face of the foreign company in Japan: visiting customer sites, managing distributor relationships, providing product support, or coordinating local logistics for the inventory cleared under IOR.
This combination is commercially coherent and legally clean. The IOR track is a goods flow and customs compliance matter. The EOR track is an employment and labor compliance matter. They run on separate contractual relationships with separate providers, though both can be run through a single counterparty like Aplash.
The monthly cost structure reflects this separation. The foreign company pays two independent invoice streams. The IOR invoice covers the goods cost, customs duties and import consumption tax passed through at cost, and the IOR service fee per shipment (or a recurring fee under an ACP arrangement). The EOR invoice covers the employee's gross salary, the employer-side statutory social insurance contributions, and the EOR service fee. These two invoice streams are administered independently; they do not merge into a single fee arrangement.
The one interaction point to manage actively is PE. If the EOR employee is concluding contracts in Japan on behalf of the foreign company as a matter of routine, that activity profile warrants a PE assessment before the arrangement goes live. The IOR track on its own does not raise PE; the employment and commercial activity track does.
When This Structure Becomes a Japan Entity
The IOR plus EOR combination is a pre-entity structure, not a permanent one. Five observable signals indicate when the structure should give way to direct entity formation.
(a) EOR headcount exceeds three to five people. EOR cost per employee is materially higher than direct employment because the EOR service fee is layered on top of salary and statutory contributions. At three to five employees, the accumulated monthly EOR premium typically approaches or exceeds the annualized cost of maintaining a small Japan KK (株式会社). At five to eight employees, the economic case for entity formation is usually clear.
(b) Japanese customers require a Japan legal entity as contractual counterparty. When the sales pipeline stalls because customers demand a Japan-incorporated vendor, the entity decision is no longer optional.
(c) Import volume is large enough that the IOR service fee plus the structural cost of the buy-and-sell IOR model exceeds the cost of a Japan entity importing directly. This threshold varies by shipment structure and goods category, but it is a concrete calculation worth running as import volume grows.
(d) Product regulatory registrations require a Japan-domiciled entity as the license holder. Certain product approvals, including medical device marketing authorization under the Pharmaceuticals and Medical Devices Act (薬機法) and specific Product Safety (PSE) designated examination body roles, require a Japan-incorporated entity or a Japan-resident party. Neither IOR nor ACP substitutes for that requirement.
(e) The company wishes to hold Japan profit within a Japan corporate structure. For tax planning, local reinvestment, or operational control reasons, some companies reach a point where Japan revenue should land in a Japan entity. That decision is structurally independent of customs and employment structure, but it often coincides with the other scale signals.
A Practical Note on Sequencing
For most companies, the operationally correct sequencing is to set up IOR or ACP first to validate product-market fit, then add EOR for the first commercial hire, then revisit entity formation at 18 to 24 months when actual transaction data is available. Attempting entity formation at the outset adds 4 to 6 weeks of incorporation work, an ongoing set of annual statutory compliance obligations, and a Japan corporate tax filing requirement before any revenue is earned. The IOR plus EOR combination is not a workaround or a second-best alternative. It is the deliberate pre-entity structure for a company that wants to test Japan before committing to the overhead of a local entity.
The question is not whether IOR and EOR can be combined. They routinely are, and the combination runs cleanly when the two invoice streams and the two contractual relationships are kept structurally separate. The real question is whether the combination covers everything a specific company needs in Japan. For a product-plus-people market entry, with goods coming in and one or two commercial hires operating locally, it almost always does.
