Incorporating a Japan entity ends your ACP appointment, because the structure only exists for a non-resident importer under Customs Act (関税法) Article 95. Once your company has a registered office in Japan, it is no longer the non-resident the appointment was built around, it becomes its own importer of record, and the ACP relationship with your resident agent has to be re-evaluated rather than continued as-is.
Why Does Incorporating Change Your ACP Status?#
Article 95 of the Customs Act (関税法第95条) makes an ACP appointment, formally a Customs Procedure Agent (税関事務管理人), available only to an importer with no address, residence, or office in Japan. The appointment exists to give Japan Customs (税関) a resident point of contact for a principal it otherwise could not reach domestically.
A newly incorporated KK or GK has a registered office in Japan by definition, so the non-resident prerequisite that the whole appointment rests on no longer holds. The company has not lost the ability to import; it has gained the ability to be its own importer, which is a different structure with a different filing party.
What Does "Re-Evaluated" Actually Mean in Practice?#
It means the ACP appointment does not automatically continue once the underlying non-resident status ends, and someone has to decide what replaces it before the next shipment. Three things change at once: who is named as importer of record, who Japan Customs treats as the responsible party, and which filings apply going forward.
Key points:
(a) The newly incorporated entity becomes its own importer of record (輸入者) on 輸入申告 going forward, rather than the non-resident principal the ACP was appointed to represent.
(b) As its own importer, the entity can engage a licensed customs broker (通関業者) directly for clearance, the same way any Japan-resident company does, without needing a 税関事務管理人 appointment at all.
(c) The timing of the cutover matters because an ACP appointment cannot be backdated to cover a shipment after the fact, so a shipment that straddles the incorporation date needs a clear answer on which structure it is filed under before it is filed, not after a rejection.
Does the Old ACP Appointment Need to Be Closed Out Formally?#
Yes, in substance: the appointment was notified to a specific Customs office under the non-resident's name using Customs Form C No. 7500 (税関事務管理人届出書), and that notification was built on a prerequisite that no longer applies. Treat the transition as something that needs Customs correspondence, not something that lapses quietly on its own, since a resident agent still shown as the registered contact for a principal that technically no longer qualifies as non-resident is a loose end on Customs' own records, not just on yours.
This is also the point to settle commercially, not just procedurally. If the new entity still wants a provider coordinating customs work, that relationship becomes a conventional customs-broker engagement under the entity's own import registration, structurally distinct from the ACP role under Article 95. The ACP as a permanent import strategy guide covers the reverse decision, staying non-resident versus incorporating, and the same factors (banking timeline, visa plans, volume) determine whether incorporating mid-engagement was the right call or premature. A provider switch for other reasons, rather than a change in residency, is covered separately in the ACP provider transition guide.
Frequently Asked Questions#
Can my company keep using the same ACP agent after incorporating in Japan, just under a different arrangement?
The same firm can continue coordinating customs work, but not as your 税関事務管理人, because that role under Customs Act Article 95 only applies to a non-resident importer. Once incorporated, your company engages a licensed customs broker (通関業者) directly as its own importer of record, which is a structurally different relationship even if the day-to-day customs coordination looks similar.
What happens to a shipment that is already in transit when my incorporation is registered?
Because an ACP appointment cannot be backdated, the safer approach is to settle in advance which structure handles any shipment that straddles the incorporation date, rather than filing first and sorting it out after Customs flags a mismatch. In most cases this means timing the final ACP-filed shipment and the first self-filed shipment around the registration date, rather than letting one shipment try to split the difference.
Do we have to notify Japan Customs separately when the ACP appointment ends?
The original appointment was notified to a specific Customs office under Customs Form C No. 7500, built on the non-resident prerequisite, so treat the transition as something to settle with that same Customs office rather than something that resolves itself once the entity exists. Confirm the specific notification step with your customs agent or broker before the first self-filed shipment, since the exact handling can depend on which Customs office holds the original record.
Conclusion#
Incorporating in Japan is usually a sign the business has outgrown the non-resident structure, not a complication to route around. The ACP appointment ends because its legal basis does, the new entity becomes its own importer, and the work shifts to a direct broker relationship rather than a continued agent appointment.
