Restricted-party screening tells an Importer of Record whether it is safe to do business with a counterparty. It does not tell anyone whether the goods themselves are legal to bring into Japan. Those are two separate questions, and a shipment can clear the first and still fail the second. This post is a general educational overview of the goods-side question: the broad categories of items Japan Customs (税関) treats as prohibited or restricted, why an Importer of Record (IOR) or Attorney for Customs Procedures (ACP, 税関事務管理人) provider reviews goods independently of counterparty screening, and what happens in practice when a restricted or prohibited item reaches the border anyway. It is not a determination for any specific product and it does not cover export control classification, which is a distinct regulatory question addressed elsewhere.
Two Different Compliance Checks, Not One
An IOR or ACP provider's compliance review has at least two independent layers, and conflating them is a common source of confusion.
Counterparty screening asks who is on the other side of the transaction: is the buyer, seller, consignee, or end-user a sanctioned party, a denied entity, or otherwise a name that should stop the deal before it starts. That process is covered in the companion post on denied-party screening for Japan IOR engagements and is not restated here.
Goods-side compliance review asks a different question entirely: is this specific item, regardless of who is buying or selling it, something Japan Customs will refuse to release, or something that requires a permit, certificate, or license from a specific ministry before release is possible. A shipment can involve two entirely clean, unlisted counterparties and still be stopped at the border because the item itself falls into a restricted or prohibited category. An IOR or ACP provider that only screens counterparties and skips the goods-side review is not doing a complete compliance job, and a shipment can be paused or declined on goods-side grounds alone, independent of any counterparty finding.
Prohibited Goods: Absolute Bars
Certain categories are prohibited from import into Japan outright. No permit, certificate, or license converts a prohibited item into an importable one; the only paths are non-import or, in narrow legally defined cases, destruction or forfeiture through customs procedure. Categories generally treated this way include:
(a) Narcotics, psychotropic substances, and controlled drugs covered under Japan's narcotics and stimulant control framework, including precursor chemicals in certain forms;
(b) Counterfeit goods and other items infringing intellectual property rights (trademark, patent, copyright, design), which Customs treats as prohibited imports under intellectual-property enforcement provisions rather than a licensing regime;
(c) Obscene materials as defined under Japan's public morals and obscenity provisions, assessed on a case-by-case basis by Customs;
(d) Counterfeit currency, forged securities, and forged official documents;
(e) Certain categories of goods that infringe on public safety or morals in ways specifically enumerated in Japan's customs legislation.
These are absolute bars, not permit gates. If an item falls into one of these categories, no downstream paperwork fixes the problem; the correct action is to not attempt the import.
Restricted Goods: Permit-Gated, Not Barred
A separate, larger category is not prohibited outright but is restricted pending clearance from a specific ministry or agency outside Customs itself. Customs will not release these goods on a standard import declaration; release depends on a permit, certificate, license, or notification issued by the competent authority for that category. Examples of the general shape of this category, at an educational level only:
(a) Firearms, ammunition, and specified parts, which require permits under Japan's firearms and swords control framework and are handled through police and public safety authorities rather than Customs alone;
(b) Certain plants, animals, and products derived from them, including species and derivatives covered under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES, ワシントン条約), which require export/import permits issued by the exporting and importing countries' CITES management authorities, and separately, plants and animals subject to quarantine inspection under Japan's plant and animal quarantine regimes;
(c) Certain chemicals, which may require notification or approval depending on the specific substance and its classification under Japan's chemical substance control and industrial safety frameworks; the specific determination for any given chemical is a separate, product-specific exercise and is not addressed here;
(d) Certain foods, pharmaceuticals, cosmetics, and medical devices, which require clearance from the health ministry's regulatory framework before customs release, distinct from the customs declaration itself;
(e) Certain used goods, secondhand articles, and specified consumer products subject to separate safety-certification schemes before import.
The defining feature of a restricted item is that it can be imported, but only after the correct ministry has issued the correct document, and only if that document is in place before or at the time of customs declaration. Attempting the shipment first and seeking the permit afterward does not work; Customs generally will not release restricted goods on the promise that paperwork is forthcoming.
Why This Sits Outside FEFTA/Export-Control Classification
Some of these same product categories, particularly dual-use items, chemicals, and certain electronics, also intersect with a completely separate regulatory question: whether the item's export from Japan (or in-country transfer to a non-resident) requires a determination under the Foreign Exchange and Foreign Trade Act (外為法, FEFTA). That is a distinct legal framework governing outbound flows, technology transfer, and end-use screening, not an import-side restriction. The FEFTA classification exercise is covered in a separate post on FEFTA-related import clearance considerations and is intentionally not duplicated here. A goods-side restriction on import into Japan and a FEFTA determination on export from Japan are two different regulatory questions that happen to sometimes touch the same product; do not treat clearing one as clearing the other.
Why an IOR or ACP Provider Reviews Goods Before Committing
An IOR takes legal title to goods and is named as the importer on the customs declaration (輸入申告); an ACP provider acts as procedural agent for a non-resident importer under Article 95 of the Customs Act (関税法第95条). In both structures, the party named in the customs process has a direct stake in whether the goods are even legally importable, independent of whether the counterparty passed screening. That is why a competent IOR or ACP engagement includes a goods-level compliance review as a distinct step, checked before a shipment is booked, not discovered at the port.
This review typically asks, at minimum: does this item fall into an absolutely prohibited category; does it fall into a restricted category requiring a specific ministry's permit, and if so, is that permit already secured; and does the shipment intersect with a separate regulatory regime (dangerous goods classification, for instance, covered in a companion post on dangerous goods import into Japan) that changes handling requirements even where the item is not prohibited or restricted in the narrower sense addressed here. Where a shipment touches export-control-adjacent territory, FEFTA, dual-use, or defense-adjacent categories, that determination requires a separate, more specific analysis and escalation path; it is not resolved by the general goods-restriction review described in this post.
The Practical Consequence of Getting This Wrong
Attempting to import a prohibited or restricted item without the required permit does not typically result in a warning and a chance to correct course. In general terms, and without citing specific penalty figures or procedural outcomes, which vary by category and circumstance and are outside the scope of a general educational post, the practical exposure looks like this:
(a) Clearance refusal. Customs declines to release the goods, and the shipment does not proceed as planned.
(b) Seizure or forfeiture. For prohibited items in particular, Customs can seize the goods, and they may not be returned to the shipper or importer.
(c) Exposure for whoever is named as importer. Whether that is the client acting as its own importer, a non-resident principal under an ACP appointment, or Aplash acting as IOR under a buy-and-sell structure, the named importer is the party Customs holds accountable for the declaration. A false or non-compliant declaration creates direct exposure for that named party, which is precisely why the goods-side review happens before the IOR or ACP relationship commits to a shipment, not after.
None of this is a substitute for a specific determination on a specific product. If a shipment involves a category discussed here, plants and animals, chemicals, firearms-adjacent items, or medical and food products, the correct next step is a product-specific classification exercise against the current rules for that category, not reliance on a general overview.
Conclusion
Counterparty screening and goods-side restriction review answer different questions, and a shipment can pass one while failing the other. Prohibited goods have no permit path; restricted goods have a permit path that must be completed before the shipment moves, not after. An IOR or ACP provider's goods-level review exists to catch these categories at the planning stage, because the party named on the customs declaration carries the exposure if it does not. Where a shipment also touches export-control or dual-use questions, that is a separate determination handled through its own process, not folded into a general goods-restriction check.
