No. A Japan ACP (Attorney for Customs Procedures / 税関事務管理人) appointment under Article 95 of the Customs Act (関税法第95条) is recorded with one Customs office at a time. Bringing goods through a second port of entry requires a separate notification filed with that office. One appointment does not automatically extend across every port a non-resident importer might use.
Does a Japan ACP Appointment Automatically Cover Multiple Ports?
No, it does not. The appointment is recorded office by office: one 税関事務管理人届出書 (Attorney for Customs Procedures notification, Customs Form C No. 7500) filed with the specific Customs office where import procedures will be performed puts the appointment on record for that office only.
If a non-resident importer plans to bring goods in through, for example, Tokyo Customs and later Osaka Customs, each office needs its own filing before the non-resident's agent has standing to act there. This is the same logic covered in the ACP registration and setup guide: the appointment is a legal authority granted at a specific office, not a blanket credential that travels with the importer nationwide. Confirming the intended port mix before the first filing avoids a mid-shipment scramble to add a second office.
What Is the Legal Basis for the Per-Office Filing Requirement?
Article 95 of the Customs Act (関税法第95条) requires a non-resident who must perform customs procedures in Japan to appoint a Japan-resident agent, but it does not create a single nationwide registration. Japan Customs treats the notification as a record held by the receiving office, so the statutory mechanism is inherently local to wherever the notification lands.
This matters for how the arrangement should be described to a client or partner. The 税関事務管理人届出書 is a 届出 (notification) that Customs records, not a 承認 (approval) or 許可 (permit) granted after review. Framing an additional-port filing as "getting approved for a new port" overstates what is happening: the filing puts the agent on record at that office so the office has a name and a contact when a declaration under that appointment is filed there.
What Form Do You File to Add a Second Customs Office?
The same form used for the first appointment: the 税関事務管理人届出書 (Customs Form C No. 7500), filed again, addressed to the new Customs office. The filing is submitted in two copies, the 原本 (original) retained by Customs and a 交付用 (issuance copy) returned to the filer as evidence the notification is on record.
Nothing about the form itself changes for a second or third port; what changes is which Customs office receives it and confirms the office-specific requirements at the pre-consultation stage before submission. The ACP appointment timeline guide walks through how long that Track A sequence typically runs for a first filing, and the same sequence, document pack, pre-consultation, filing, recording, applies to each additional office rather than compressing on repeat.
How Does Multi-Port ACP Compare to Multi-Brand ACP Arrangements?
Multi-port and multi-brand are two separate axes of the same appointment structure, and they do not solve each other. A multi-port need arises when one non-resident principal imports through more than one Customs office; a multi-brand need arises when one non-resident principal sells more than one brand or product line through the same office. The multi-brand shared ACP arrangement addresses the second axis directly, and it is worth reading alongside this one precisely because the two get conflated: adding a brand under an existing appointment is not the same action as adding a Customs office, and neither substitutes for the other.
A non-resident principal expanding into three ports and two brands needs both extensions handled on their own terms: the port question resolved by separate 税関事務管理人届出書 filings per office, and the brand question resolved by whatever scope language the existing appointment and agreement already cover. Ongoing maintenance across either axis, KYC continuity, appointment review, correspondence handling, is the subject the ACP annual renewal and ongoing compliance guide covers in detail.
Key points:
(a) One 税関事務管理人届出書 (Customs Form C No. 7500) filing covers exactly one Customs office; a second port of entry requires its own separate filing at that office.
(b) The notification is a 届出 recorded by Customs, not a 承認 or 許可 granted after review, so an additional-port filing should never be described to a client as Customs "approving" the new port.
(c) Confirming the full intended port mix during the document-pack stage, rather than after the first appointment is already on record, keeps the filing sequence from running one office behind actual shipping plans.
Frequently Asked Questions
If I already have an ACP appointment at one Japan Customs office, can I just tell my broker to use it at a different port?
No. The appointment only gives the agent standing at the Customs office where the 税関事務管理人届出書 was filed and recorded. A different office has no record of the appointment until a separate notification is filed there, so a broker filing a declaration at an unregistered office on the strength of the first appointment is filing without a recorded agent behind it.
Does adding a second port require a new engagement agreement, or just a new form?
The additional-port step is a separate 税関事務管理人届出書 filing with the new Customs office; whether it also requires amending the existing commercial agreement depends on whether the original agreement's scope already contemplated the port mix. This is a structural distinction the ACP setup guide and /acp service page both cover: the notification is the legal-authority instrument, and the agreement is the separate commercial contract, so an added port can require touching either one or both depending on how the original scope was written.
How long does filing at an additional Customs office usually take once the first appointment is already on record?
Aplash's own operating estimate for a first appointment, from a complete document pack to the notification recorded, runs one to two weeks, covering the document pack, pre-consultation with the office, filing, and recording; this is a firm delivery estimate, not a published statutory turnaround, since Customs sets no fixed processing period for the form. An additional-port filing follows the same sequence at the new office, so the same range is a reasonable planning estimate, though it is not a guaranteed date.
Conclusion
A Japan ACP appointment is scoped to the Customs office where it is filed and recorded, not to the non-resident importer generally. Each additional port of entry is a separate 税関事務管理人届出書 filing at that office, following the same document-pack, pre-consultation, and recording sequence as the first appointment. Planning the intended port mix before the first filing, rather than discovering a second office is needed mid-shipment, keeps the appointment structure aligned with actual import flow.
