As previously mentioned in another article (“Announcement from Japan Customs | Mandatory to use ACP in Many Cases – Attorney for Customs Procedure”),
since October 2023, overseas sellers (especially those selling via e-commerce platforms such as Amazon, Rakuten, and Shopify) are required to act as the Importer of Record (IOR) themselves by appointing an Attorney for Customs Procedures (ACP).
Under this revised system, using another Japanese company as a nominal importer is no longer permitted.
Nevertheless, we continue to observe cases in which certain entities provide IOR name-lending services that are not legally recognized under Japanese law.
Such practices have become widespread, prompting us to issue this notice as a compliance warning.
Sellers operating in Japan are expected to understand Japan’s legal framework correctly.
Problematic Practices – Violation of Customs Laws
Some entities fabricate documents, such as invoices, to make it appear as though a sale occurs between the overseas seller and the Japanese IOR, when in fact the declared import price is set extremely low—often close to manufacturing cost.
Even if a formal sale exists, when the IOR temporarily “purchases” the goods at import and immediately resells them back, such an IOR cannot be regarded as a genuine importer under Japanese law.
In many cases, products are not shipped directly to Amazon’s fulfillment centers but are first sent to domestic warehouses for relabeling or repackaging before re-shipment.
Import documents often omit any mention of the e-commerce warehouse, and the products themselves bear no e-commerce identifiers.
This arrangement is designed to avoid customs scrutiny regarding valuation methods (e.g., customs valuation based on domestic retail price), and thus constitutes a non-compliant import practice.
Legal Risks and Liabilities
When imports are declared with undervalued invoices or in violation of import regulations, even if customs clearance is initially granted, post-clearance audits by Japan Customs may result in substantial additional duties and penalties.
Legally, the IOR bears responsibility for such liabilities. However, if the overseas seller is the true economic beneficiary, disputes between the overseas seller and the nominal IOR are almost inevitable.
When the overseas seller avoids all import-related taxes and leaves all handling to the IOR, the IOR effectively assumes the legal and financial risk.
While some IOR service providers may claim this is a legitimate business model, in reality such practices undermine Japan’s legal integrity and fair market environment, prioritizing short-term profit over compliance and responsible trade.
Impact on Fair Market Competition
Products imported through improper schemes often appear at unrealistically low prices on platforms like Amazon.
This places legitimate sellers—who properly pay import duties and consumption tax—at a competitive disadvantage, eroding fair and transparent market conditions.
It was precisely this issue that led to Japan’s customs system reform in October 2023, which clarified the concept of the “substantive importer” and reinforced the ACP framework.
While overseas sellers who unknowingly rely on unlawful schemes also bear some responsibility, the primary accountability lies with IOR providers who knowingly engage in these practices.
Low-compliance businesses often violate not only customs valuation rules but also intellectual property, consumer safety, and tax laws, indicating broader systemic non-compliance.
Message from ACP JAPAN
At ACP JAPAN, we assist overseas sellers establish fully compliant import structures in Japan through the ACP (Attorney for Customs Procedures) system.
To build a sustainable and trustworthy business in the Japanese market, we strongly encourage overseas sellers to act as the true importer—not through nominal name-lending schemes, but under a legitimate and transparent framework in accordance with Japanese law.
Concerns Over Cost Impact of Customs Valuation/Import Declarations
When overseas sellers import goods for e-commerce into Japan, whether through ACP or as the another IOR company, there is no “import transaction” with a Japanese buyer, leading to the exceptional determination method for declared import values, typically based on the domestic selling price.
There are concerns about high valuation leading to excessive duties and taxes. However, this is a determination method based on the Customs Tariff Law, which must be adhered to. The cost impact of the valuation is not as significant as often feared.
The taxes on import are mainly customs duties and consumption tax. Japan’s import tariffs are relatively low on a global scale, and many industrial products are duty-free. As for consumption tax, which is a uniform 10%, it is an indirect tax borne by the final consumer, not a cost for the overseas seller. Taxable businesses regularly file consumption tax returns to the tax office, adjusting the tax paid on imports against the tax collected from sales, neutralizing the cost impact. However, this necessitates that the overseas business itself becomes the importer, achievable only through using ACP.
With the start of the consumption tax invoice system in October 2023, many overseas businesses might have registered as qualified invoice-issuing entity. For B2C businesses, registration as a qualified invoice-issuing entity is not always necessary, but many companies seem to register without fully understanding the system. I recommend that overseas businesses seek advice from qualified professionals to navigate these changes correctly.

Please Be Careful
In cases where foreign corporations (non-residents) without an office in Japan import goods, failure to properly prepare an Importer of Record (IOR) through an Attorney for Customs Procedures (ACP) or similar means can result in goods being held at customs, leading to significant delays and costs. To avoid such risks, please make thorough preparations.
If an ACP is needed, it is crucial to utilize the services of an experienced ACP well-versed in customs-related laws and regulations. The import and export operations of non-residents/foreign corporations using an ACP are treated as unique cases. Many customs brokers are not familiar with these procedures, leading to incidents where goods are detained for extended periods due to unsuccessful explanations to customs. (Customs will not permit the import if the explanations provided by the importer or customs broker are unsatisfactory, resulting in the goods being detained until customs is convinced.)
We highly recommend utilizing our services as professional experts in customs, knowledgeable about customs-related laws and regulations. With a proven track record of resolving numerous issues through direct consultations with customs officers and customs brokers, our clients supported as an ACP now exceed 200 companies. We are committed to delivering industry-leading results with our expertise.
