Getting an Attorney for Customs Procedures (税関事務管理人) appointment registered with Japan Customs is the beginning of the arrangement, not the end of it. Once the notification is filed and the first shipment clears, non-resident companies routinely ask the same follow-up question: is this a one-time filing, or does it require active maintenance for as long as we keep importing? The correct answer is that ACP is a continuing appointment, not a one-time filing, and treating it as "set and forget" is the single most common way non-resident importers end up with a clearance problem they did not see coming.
ACP Is a Standing Appointment, Not a Filing Event
The Customs Act (関税法) Article 95 appointment stays in effect for as long as the non-resident company is importing through that customs office and remains a non-resident. There is no fixed expiry date printed on the notification the way there is on, say, a visa. But "no expiry date" does not mean "no maintenance." The appointment is a live representation to Japan Customs that a specific Japan-resident agent stands behind the non-resident's import activity. If the facts underlying that representation change and the notification is not updated, the appointment does not automatically become invalid on a fixed timetable, but it becomes stale, and a stale notification creates exactly the kind of procedural exposure that surfaces at the worst possible moment: when a shipment is sitting at the port.
What "Maintaining" the Appointment Actually Involves
Three categories of ongoing work sit underneath a live ACP appointment.
(a) Periodic tax filings tied to Qualified Invoice System (インボイス制度) status. Once the non-resident company is registered as a Qualified Invoice Issuer (適格請求書発行事業者), it has an ongoing filing obligation with the National Tax Agency (国税庁) for consumption tax (消費税) returns, submitted through its appointed Tax Representative (納税管理人). The exact filing frequency depends on the non-resident's taxable sales volume in Japan and the specific tax period it has elected, and it is not something we will assert as a fixed universal cadence here. Companies should confirm their applicable filing schedule directly with their Tax Representative or a licensed tax accountant (税理士) rather than assuming a standard calendar.
(b) Keeping registered details current with Japan Customs. The ACP notification (税関事務管理人届出書) on file names the non-resident company, its authorized representative, and the customs office(s) covered. Any change to the company name, registered address, authorized signatory, or intended port of entry needs to be reflected in an updated filing. Customs does not track these changes automatically; the ACP provider has to submit the update.
(c) Notifying customs of any change in status. This covers more than paperwork housekeeping. If the non-resident's import volume changes materially, if it changes the goods it is importing in a way that shifts tariff classification exposure, or if its business relationship with the ACP provider itself changes, Japan Customs needs to be able to reach the party who is actually responsible for the account. An ACP provider that has gone unresponsive, or a notification that still names a representative who has left the company, is a gap that only becomes visible when something goes wrong.
None of this is exotic. It is closer to the kind of ongoing corporate housekeeping that any regulated appointment requires. The point is simply that it exists, and that a company evaluating ACP providers should ask about it up front rather than assuming the relationship ends at onboarding.
Events That End or Require Updating the Arrangement
Several concrete events change the ACP arrangement rather than just requiring a routine update.
Change of ACP provider. If the non-resident switches from one Japan-resident agent to another, this is not an internal handover; it requires a new notification naming the new agent and, typically, formal closure of the old one. Shipments should not be scheduled to clear during the gap between the old notification lapsing and the new one taking effect.
The non-resident company changing its Japan activity, such as incorporating a local entity. ACP is only available under Article 95 while the client remains a non-resident of Japan, meaning no address, residence, or office in Japan. If the company incorporates a Japan entity, the entire ACP structure has to be re-evaluated, because the legal basis for the appointment no longer holds once the importer has a Japan presence of its own. This is not a minor administrative note; it is a structural trigger that should prompt a conversation with the ACP provider before, not after, the incorporation closes.
Voluntary termination of imports. If the non-resident stops importing into Japan, the ACP appointment and any related Tax Representative and Qualified Invoice System registrations should be formally wound down rather than left dormant. An appointment left open with no active shipments still carries record-retention and correspondence obligations, and a change of address or contact detail that never gets updated on a dormant filing is exactly the kind of thing that turns into a problem if imports resume later without anyone revisiting the file.
What Happens If the Appointment Lapses While Shipments Are Still Inbound
This is the scenario companies most need to plan around, because the operational consequences land at the border, not at a desk.
(a) Clearance delays or outright refusal. Japan Customs requires a valid resident agent on file before it will process an import declaration naming a non-resident as the importer. If the ACP notification has lapsed, been closed, or gone stale because the named representative is no longer reachable, there is no valid agent standing behind the declaration. Goods can sit at the port while the gap is sorted out, and in a worse case the declaration can be refused outright until a compliant appointment is back in place. For a company with recurring shipments, this is not a one-time inconvenience; every shipment behind the stalled one queues up.
(b) Consumption tax deductibility risk. The JCT input credit chain runs through the Tax Representative and Qualified Invoice System registration, both of which are tied to the same underlying non-resident status and often the same provider relationship as the ACP appointment. If that chain breaks, for example because the Tax Representative appointment lapses alongside the ACP notification, import consumption tax paid at clearance can become an unrecoverable cost rather than a creditable one. This is the same permanent-loss dynamic that applies to a mis-sequenced initial setup, except here it is triggered by neglect of an existing relationship rather than a setup-stage error.
(c) Reputational and compliance-history risk with Customs. Japan Customs maintains a working relationship with the parties it deals with regularly. A non-resident importer whose agent appointments lapse, get closed and reopened repeatedly, or require correction at clearance time builds a compliance history that customs officers and the assigned customs broker (通関士) both notice. This does not carry a fixed penalty figure that we would state here, and any suggestion of a specific fine or sanction should be confirmed directly with Japan Customs or a qualified customs specialist rather than assumed from general commentary. What is consistent across cases is that a track record of lapses invites closer scrutiny on future filings, which slows down exactly the shipments a company needs to move quickly.
What to Ask an ACP Provider Before Signing Up
Given that continuity, not the initial filing, is where most operational risk actually sits, a non-resident company evaluating ACP providers should ask, before signing:
(a) What is included in ongoing maintenance versus billed separately, and how are notification updates (name, address, representative, port changes) handled when they arise;
(b) Who is responsible for monitoring the Qualified Invoice System filing obligations tied to the appointment, and what happens if the company's Japan import volume or tax period changes;
(c) What the transition process looks like if the company ever needs to change ACP providers, including how the outgoing and incoming notifications are sequenced to avoid a coverage gap;
(d) What triggers a mandatory re-evaluation of the arrangement, particularly a change in Japan residency status such as incorporating a local entity;
(e) How the provider handles a lapse or gap that occurs with shipments already in transit, and what the realistic clearance impact is if that happens.
A provider that cannot answer these questions clearly before the engagement starts is unlikely to manage them well once shipments are actually moving. ACP is a relationship that needs to be actively held, not a document that gets filed once and forgotten.
