Once a company decides it needs an Importer of Record (IOR) in Japan, the next question is almost always practical: what actually has to happen, in what order, before the first shipment can clear customs? This post walks through the complete setup process from first contact to first cleared shipment, so a team scoping a Japan launch can plan the real sequence of steps rather than treating IOR as a single opaque service.
Step 1: Confirm IOR Is the Right Structure
Before any setup work begins, confirm that IOR, rather than the alternative non-resident structure, actually fits the situation. Under IOR, the provider (Aplash) purchases the goods from the overseas seller, clears customs in its own name, and re-sells to the Japan buyer, meaning the foreign company never appears on the import declaration (輸入申告). This differs from an Attorney for Customs Procedures (税関事務管理人) appointment under Customs Act (関税法) Article 95, where the foreign company remains the named importer and the Japan-resident agent handles only the procedural side. The two are not interchangeable, and confirming which one matches the commercial goal (hand off the importer role entirely, versus keep it while getting local procedural support) is the first real decision, before any paperwork starts.
Step 2: Onboarding and KYC
Once IOR is confirmed as the right structure, the provider runs know-your-customer (KYC) checks on the client entity: corporate registration documents, beneficial ownership information, and a description of the goods and end use. This step exists because the provider is about to take on legal importer liability and needs to understand exactly what it is agreeing to import and re-sell. Expect to provide standard corporate documentation (certificate of incorporation, or equivalent, and basic ownership structure) at this stage. Companies with sensitive end uses, defense-adjacent goods, or export-control-flagged products should expect a longer KYC review at this step, since those categories carry additional screening before any commercial commitment is made.
Step 3: Product and Regulatory Scoping
Before quoting the engagement, the provider determines the correct HS code classification for the goods, since that classification drives the customs duty rate and identifies whether the product falls under any Japan-specific regulatory regime: PSE / Electrical Appliance and Materials Safety Act (電気用品安全法) for electrical goods, Radio Act (電波法) certification (技適) for wireless devices, the Food Sanitation Act (食品衛生法) for food and food-contact products, or the Pharmaceuticals and Medical Devices Act (薬機法) for medical devices. This step matters because it determines both the fee structure and, more importantly, whether pre-import compliance work (testing, certification, notification) needs to happen before the first shipment can legally clear. Skipping this step and shipping first is the most common cause of goods being held at the border on a first-time Japan import.
Step 4: Commercial Structuring
IOR is not a nominal name-lending arrangement. Under the Customs Act (関税法), the entity named on the import declaration must be the entity with actual legal title to or rights over the goods at the point of declaration. This means the setup includes a genuine three-part commercial structure: a purchase agreement under which the provider buys the goods from the overseas seller, a re-sale agreement under which the provider sells to the Japan buyer, and a service agreement covering the IOR compliance and coordination work itself. Each of these is a real contract, not a formality, because a nominal arrangement with no underlying commercial substance would constitute a false customs declaration under Japanese law.
Step 5: Consumption Tax Structure
Japan's import consumption tax (輸入消費税) is assessed at the border and, for a properly structured commercial chain, is recoverable rather than a permanent cost. The IOR provider pays the import consumption tax as the named importer, then issues a qualified invoice (適格請求書) on the re-sale to the Japan buyer, which allows the buyer to claim the corresponding input tax credit. Confirming this chain is set up correctly, and that the Japan buyer is a registered qualified invoice recipient if applicable, is part of setup rather than an afterthought handled after the first shipment.
Step 6: Engagement Agreement and Fee Confirmation
With the product, regulatory scope, and commercial structure confirmed, the provider issues a formal service agreement covering the scope of the IOR engagement, the fee structure, and the operational responsibilities on each side (who provides which shipping documents, who confirms delivery instructions, how customs examination outcomes are handled if a shipment is selected for inspection). This is the point at which a specific fee proposal, scoped to the actual product and volume profile rather than a generic estimate, is confirmed.
Step 7: First Shipment Documentation
For the first actual shipment, the overseas seller provides a commercial invoice addressed to the IOR provider, a packing list, and a bill of lading or air waybill naming the provider as consignee, along with any export licence documentation required on the seller's side. The provider files the import declaration in its own name, pays the applicable customs duty and import consumption tax, and coordinates release of the goods. This first shipment is typically where any documentation gaps from earlier steps surface, which is why the scoping and structuring steps above exist: they are meant to catch problems before the goods are already in transit.
Step 8: Ongoing Operation
After the first shipment clears, subsequent shipments follow the same documentation flow with the structure already in place. Companies with recurring shipment volume can move to a retainer-style arrangement that reflects the ongoing relationship rather than re-scoping each shipment individually. This is also the point at which a company should periodically revisit whether IOR remains the right structure: rising volume, a shift toward wanting to remain the named importer, or the eventual decision to incorporate a Japan entity are all reasons the structure decision from Step 1 gets revisited over time rather than treated as permanent.
Realistic Timeline
Setup from initial engagement to first cleared shipment typically runs a few weeks rather than months, assuming the goods do not require pre-import regulatory certification (PSE testing or Radio Act certification, for example, add lead time of their own and should be scoped and started separately from the commercial IOR setup as early as possible). Companies with straightforward commercial goods and no product-specific regulatory overlay generally move fastest; companies with regulated products should expect the certification lead time, not the IOR commercial setup, to be the pacing item.
What Slows the Process Down in Practice
A few recurring patterns extend the timeline beyond the baseline above. Incomplete or inconsistent product documentation delays the HS classification and regulatory scoping step. Ambiguity about beneficial ownership or end use extends KYC. Treating a product's regulatory certification (PSE, Radio Act, food notification) as something to figure out after the commercial agreement is signed, rather than in parallel with it, is the single most common cause of a first shipment arriving at Japan Customs before it is actually ready to clear.
Conclusion
Setting up an IOR in Japan is a sequence of concrete, ordered steps: confirm the structure fits, complete KYC, scope the product and its regulatory overlay, put a genuine commercial structure in place, confirm the consumption tax recovery chain, sign the engagement agreement, and only then ship. Companies that treat these as parallel tracks, particularly product regulatory certification, move faster and avoid the most common failure mode: a shipment that arrives at the border before the underlying structure or compliance work is actually finished.
