Most companies that import into Japan without a Japan entity make one structural decision early: whether Aplash takes title as Importer of Record (IOR), or the non-resident company remains the importer on record while Aplash acts as Attorney for Customs Procedures (税関事務管理人) under the Customs Act (関税法). That decision gets made once, under the conditions that existed at the time, and then the business keeps moving. Import volume grows. Product lines expand. A Japan sales presence gets built out. None of that is a reason to revisit the structure on its own, but it is exactly the kind of change that quietly turns a correct initial choice into a poor current fit. This is a diagnostic for that second moment: the signals that tell you your existing structure, whichever one it is, has stopped matching the business it now serves.
This Is a Different Question Than the One You Answered Before
The initial IOR versus ACP decision is usually framed around a single variable: does the company have a Japan address, residence, or office. If yes, neither service applies and the company files as its own resident importer. If no, the remaining question is whether the company wants to hold the importer position itself, non-resident but named on the import declaration (輸入申告) with Aplash as its Japan-resident procedural agent under Customs Act Article 95, or whether it wants Aplash to hold that position instead through a genuine buy-and-sell arrangement. That is a static comparison, made against a snapshot of the business.
The question this article addresses is dynamic: given how the business has actually developed since that first decision, does the structure still match the risk profile, the cash flow pattern, and the commercial substance on the ground today. A structure that was clearly correct at the time of setup can become a poor fit eighteen months later without anyone having made a mistake. Recognizing that shift early is what separates a planned structural transition from a forced one.
Signals That an ACP Structure No Longer Fits
Under Attorney for Customs Procedures, the client remains the named importer throughout. That was likely the right call when import volume was modest and consumption tax (消費税) recovery economics mattered more than the compliance overhead of holding the importer position. A few signals suggest that calculus has shifted.
Import value and post-clearance audit exposure have both grown. As a company's cumulative import value and shipment frequency rise, so does the likelihood of drawing a post-clearance audit review from Japan Customs (税関). Under ACP, that audit exposure lands on the named importer, which is the client, not on Aplash. A company that was comfortable carrying that exposure at a modest volume may find it materially heavier once shipment count and declared value scale up. What the current audit-selection pattern actually looks like for a given volume band should be confirmed directly with Japan Customs or a licensed customs specialist (通関士); this article is not the source for that figure.
The working capital drag from paying duty and consumption tax directly has become material. As the named importer, the client pays import duty and consumption tax at clearance out of its own cash, then recovers the consumption tax component through its own filing once the Tax Agent (納税管理人) and Qualified Invoice Issuer (適格請求書発行事業者) registrations are in place. At low volume this is a manageable timing gap. At higher volume, the cash tied up between payment at clearance and recovery on the filing cycle can become a genuine working capital constraint, particularly if shipment cadence has accelerated faster than the recovery cycle.
The company has since established a Japan presence. This is the one signal that is not a matter of preference. Attorney for Customs Procedures is only available while the client has no address, residence, or office in Japan under Customs Act Article 95. A company that incorporates a Japan entity, opens a branch, or otherwise establishes Japan residence during the engagement has moved outside the ACP prerequisite entirely. At that point the ACP relationship must be re-evaluated as a matter of legal eligibility, not commercial preference, and the company either files as its own resident importer directly or considers whether IOR still serves a purpose for a specific product line.
JCT recovery has become more complex than the original setup anticipated. A company that started with a narrow product range and a single sales channel, and has since added product categories, sales channels, or Japan-based customers issuing their own qualified invoices, may find that the consumption tax recovery chain built for the original structure no longer cleanly matches current sales flow.
Signals That an IOR Structure No Longer Fits
Under IOR, Aplash takes title through a genuine buy-and-sell arrangement and appears as the importer on the declaration. That structure is typically chosen when a non-resident company wants a fully delegated import solution with no Japan-side registration burden of its own. A few signals suggest a company has outgrown that reason.
The company has since obtained genuine Japan-side commercial substance. A company that has built a Japan sales team, entered long-term supply or distribution arrangements with Japan buyers, or established a track record of recurring imports may now have the operational footing to hold the importer position itself, through ACP if it remains non-resident, or directly if it has since incorporated. Reclaiming that position gives the company direct consumption tax recovery on its own filing rather than leaving that recovery inside Aplash's IOR structure.
Consumption tax recovery economics have become material enough to matter. Under IOR, Aplash recovers the import consumption tax as the named importer; the client does not. For a company whose import volume was modest, that never mattered much. Once volume and value climb, the consumption tax recovery a company gives up by not holding the importer position itself becomes a real number worth revisiting.
There is a strategic reason to be named as the importer. Some companies want their own name on the import declaration for reasons unrelated to tax: building an independent compliance and classification track record with Japan Customs ahead of a future entity formation, satisfying a financing or insurance counterparty that requires the company to be the party of record, or maintaining direct control over the customs relationship rather than routing it through an intermediary's buy-and-sell structure.
What Switching Actually Requires
Moving from one structure to the other is a real change in legal relationships, not a relabeling exercise, and each direction has its own sequence.
Moving away from ACP toward IOR means the client stops being named on the import declaration. The existing Attorney for Customs Procedures appointment must be formally wound down with Japan Customs, and Aplash's role shifts from procedural agent to genuine buyer and title-holder under a back-to-back purchase and re-sale structure. The client gives up its own direct consumption tax recovery under this structure in exchange for full delegation.
Moving away from IOR toward the client holding the importer position, whether through ACP if the client remains non-resident, or directly if the client has since established Japan residence, means Aplash stops taking title and stops appearing on the declaration. A new Attorney for Customs Procedures appointment cannot be filed retroactively and cannot anticipate a future shipment; it must be confirmed on file with the relevant Customs office before any declaration is contemplated under the new arrangement. If the client has since incorporated in Japan, the Attorney for Customs Procedures route is not available at all, and the client would file directly as its own resident importer.
A Quick Diagnostic
Ask these questions against the business as it stands today, not as it stood at initial setup: has import volume or declared value grown enough to change the audit exposure or working capital picture; has the company gained or lost a Japan address, residence, or office; has consumption tax recovery become material enough to be worth holding the importer position directly; has the company built commercial substance in Japan that changes the strategic case for who appears on the declaration. A yes to any of these is a reason to revisit the structure, not necessarily a reason to change it.
Conclusion
The right import structure for a company entering the Japan market is rarely the right structure for the same company two or three years later, once volume, presence, and strategy have all moved. Treating IOR and ACP as a one-time decision made at entry, rather than a structural fit to be periodically re-checked against the current business, is how companies end up carrying audit exposure or working capital drag they never intended to accept, or leaving consumption tax recovery on the table they could otherwise be claiming. Recognizing the signal early keeps the transition planned rather than forced.
