Every guide to entering Japan without an entity covers onboarding in detail. Almost none cover what happens when a company decides to stop. Whether the reason is a strategic pivot, a disappointing sales result, or a plan to shift into a full Japan entity, the assumption is often the same: simply stop placing orders and the arrangement quietly ends. It does not. An IOR (Importer of Record) or ACP (Attorney for Customs Procedures / 税関事務管理人) relationship carries obligations that outlive the last shipment, and treating the wind-down as an afterthought is how companies end up with loose ends years after they believed the Japan chapter was closed.
Why "Stop Ordering" Is Not the Same as Exiting
An IOR or ACP structure exists to satisfy a legal requirement, not a commercial preference. That requirement does not lapse automatically the moment shipments stop. Two separate threads keep running after the last container clears customs.
The first is the compliance thread. Every import declaration filed under an IOR or ACP structure remains open to review under Japan Customs' post-clearance audit authority (事後調査). This is not tied to whether the company is still actively importing; it is tied to the record retention window under the Customs Act (関税法). Records connected to a past import must be retained and remain producible for years after the transaction, regardless of whether the commercial relationship that generated them is still active.
The second is the administrative thread. An ACP appointment is a standing legal designation recorded with a specific Customs Office, not a service subscription that silently expires. Until it is formally cancelled, the designated agent remains the statutory point of contact for that non-resident importer's customs matters.
What Continues Under an IOR Structure
When Aplash or another provider acts as IOR, the provider is the named importer and carries the direct exposure of a post-clearance audit on those historical declarations. That protects the client company from being the direct audit subject. It does not eliminate every open item on the client's side. Three categories of loose ends are common at the end of an IOR relationship.
(a) Unsold or returned inventory. Goods that cleared customs under the IOR structure but were never sold, or that come back as returns, need a disposition decision: sell-through at a discount, return to the country of origin, or formal disposal. Each path has a different customs and tax treatment, and none of them happen automatically once ordering stops.
(b) Warranty and product liability tail. If the imported goods carry a warranty period or are subject to a product recall risk, that exposure does not end when the commercial relationship with the IOR provider ends. Confirm in writing who is reachable, and on what terms, if a claim surfaces after the arrangement is wound down.
(c) Final tax reconciliation. The last shipment cleared under the IOR structure still needs to flow through a final import consumption tax (輸入消費税) filing cycle. Because Japan's Qualified Invoice System (インボイス制度) ties input tax credit eligibility to the entity that held the qualified invoice registration at the time of import, closing out that filing correctly is what determines whether the tax paid on the final shipments is actually recovered or becomes a stranded cost.
What Continues Under an ACP Structure
Under ACP, the client is the named importer throughout, so the wind-down obligation sits more directly with the client. The ACP appointment does not end when the client stops shipping; it ends when the client's ACP files a cancellation with the Customs Office where the appointment was originally recorded. Until that cancellation is filed, the designated agent remains the client's statutory representative for that customs jurisdiction, which typically means the agent continues billing a maintenance fee and continues being the party Customs will contact regarding any question tied to a prior declaration.
Companies that simply stop paying an ACP provider without formally cancelling the appointment create an unclear situation for everyone involved: the provider is still legally on record as the representative, the client believes the relationship has ended, and neither position is fully accurate until the cancellation filing is made.
The Practical Wind-Down Checklist
(a) Set a defined last-shipment date and give the provider lead time. A wind-down handled with notice allows time to plan the final tax filing cycle and resolve open inventory; a wind-down discovered after the fact from a stopped payment does not.
(b) Resolve open inventory deliberately. Decide, item by item, whether unsold stock is sold through, returned, or disposed of, and confirm the customs and tax treatment of whichever path is chosen before acting on it.
(c) Close out the final import consumption tax filing period. Confirm the last shipment's import JCT has been properly credited or reconciled before the relationship ends, not after.
(d) File the ACP cancellation, do not let the appointment lapse silently. If the structure was ACP, the client's cancellation filing with the relevant Customs Office is what actually ends the statutory relationship. Confirm this filing has been made and get written confirmation that it was accepted.
(e) Retain records for the full audit window. Import records connected to shipments cleared under the arrangement remain subject to post-clearance audit for years after the fact under the Customs Act (関税法), independent of whether the commercial relationship that generated them is still active. Keep the documentation, and know who can produce it, well past the date the last shipment cleared.
Conclusion
A Japan IOR or ACP arrangement is built to satisfy a customs law requirement, and that requirement does not end the moment a company decides to stop ordering. The compliance tail, in the form of a post-clearance audit window, and the administrative tail, in the form of a standing ACP appointment or unresolved IOR-side obligations, both persist unless they are actively closed out. Companies that plan their Japan exit with the same deliberateness as their Japan entry avoid discovering, months or years later, that the arrangement they thought had quietly ended never actually was.
