A quotation from a Japanese seller is not yet an export. Between “we agree the price” and “the container is on the water” sits a specific sequence of declarations and certificates, most of it paperwork the buyer never sees but should still understand — because a document produced in the wrong order, or by the wrong party, is what holds a shipment at the port.

What actually turns a purchase into an export
An export happens when the goods are declared to Japan Customs, the declaration is processed through NACCS, and customs grants permission to load — everything before that is a domestic sale.
Japan Customs operates the Nippon Automated Cargo and Port Consolidated System (NACCS), the electronic system through which export and import declarations are lodged and processed. In practice, the exporter or its customs broker files the export declaration electronically, referencing the commercial invoice and packing list, and customs issues export permission once the declaration is accepted. Because the declaration must be filed in Japanese and NACCS is not accessible from outside Japan, most buyers work through a Japan-based exporter of record or a customs broker rather than filing anything themselves.
| Stage | What happens | Who does it |
|---|---|---|
| Sale agreed | Price, quantity, Incoterms rule fixed | Buyer and Japanese seller |
| Commercial invoice and packing list prepared | Values, quantities, weights fixed for customs | Japanese seller or its forwarder |
| Export declaration filed in NACCS | Goods declared to Japan Customs | Exporter or customs broker |
| Export permission granted | Customs releases the goods for loading | Japan Customs |
| Goods loaded and shipped | Physical export | Forwarder / carrier |
The commercial invoice and packing list: what customs and the destination both need
The commercial invoice and packing list are the base documents every later step reads from, so an error here propagates into the customs declaration, the certificate of origin and the buyer’s own import file.
The invoice needs a description that matches the tariff classification used on the declaration, not a marketing description; a unit price and total value in the agreed currency; and the Incoterms rule and named place. The packing list needs weights, dimensions and package counts that match what is actually loaded — a mismatch here is one of the more common reasons a destination customs office queries a shipment on arrival. Because both documents are produced on the Japanese side, agree the format and the level of detail with the seller before the first shipment, not after a query comes back.
Certificate of origin: non-preferential or preferential, and who issues it
A non-preferential certificate of origin is issued in Japan by a chamber of commerce and industry on request; a preferential certificate under an economic partnership agreement is either issued by a designated body or, for a growing number of agreements, self-certified by the exporter, importer or producer — the route depends on which agreement is claimed.
For an ordinary shipment with no trade-agreement claim, a Japanese chamber of commerce and industry issues the non-preferential certificate of origin on the exporter’s application; several chambers now issue it online as a PDF carrying a QR code that a destination authority can use to verify it.
For a shipment claiming a preferential rate under an economic partnership agreement, Japan Customs describes two systems: a third-party certification system, where a designated issuing authority — the Japan Chamber of Commerce and Industry is one — issues the certificate, and a self-certification system, where the exporter, importer or producer prepares an origin declaration itself. Which system applies depends on the specific agreement: some EPAs use only third-party certification, some allow an approved-exporter self-declaration, and others (including the Japan–Australia EPA, the CPTPP, the Japan–EU EPA and the Japan–UK agreement) allow first-party self-certification by the importer, exporter or producer. Confirm the certification system under the specific agreement before promising a buyer a particular document — the wrong assumption here is a common reason a preferential claim is later refused at the destination.
| Certificate type | Who issues it | Typical use |
|---|---|---|
| Non-preferential certificate of origin | Chamber of commerce and industry, on request | No trade-agreement claim; general proof of Japanese origin |
| Preferential certificate under an EPA (third-party system) | Designated issuing authority (e.g. the Japan Chamber of Commerce and Industry) | Agreements using third-party certification |
| Preferential origin declaration (self-certification) | Exporter, importer or producer, or an approved exporter | Agreements allowing self-certification, per that agreement’s own rules |

Consumption tax: why the export invoice usually shows no Japanese tax
A sale that is genuinely exported from Japan is treated as a tax-free transaction under Japan’s consumption tax rules, because the tax only applies to consumption inside Japan.
Japan’s National Tax Agency treats export transactions as outside the scope of consumption tax, on the reasoning that consumption tax is a tax on domestic consumption and exported goods are not consumed in Japan. A Japanese seller applies this exemption to a genuine export sale, which is one reason the export documentation — the declaration, the bill of lading, proof that the goods actually left Japan — matters beyond customs: it is also the evidence the seller keeps to support treating the sale as tax-exempt. A buyer does not file anything here, but should expect the invoice to carry no Japanese consumption tax line once the export is documented, and should not be surprised if the seller asks for shipping proof to keep on file.

Incoterms from Japan: what changes depending on the rule
The Incoterms rule fixes where risk and cost pass from the Japanese seller to the buyer, and it should be agreed before the invoice is drawn up, not read off the invoice afterwards.
The same purchase in Japan can be quoted FOB a Japanese port, CIF to the buyer’s port, EXW from the seller’s premises, or on other rules, and each shifts who arranges and pays for the domestic transport in Japan, the export declaration, and the main carriage. A few points specific to buying from Japan:
- EXW leaves the export declaration and domestic transport to the buyer’s forwarder — workable if you already have a competent Japan-side agent, otherwise a source of delay, since the declaration must be filed in Japanese.
- FOB / FCA are the most common starting point for a first shipment from Japan, because the seller (who can file in Japanese) handles the export side and the buyer’s forwarder takes over from the Japanese port or a named place.
- Whichever rule is used, confirm in writing which side arranges the export declaration — Incoterms rules fix cost and risk, not who physically talks to Japan Customs, and that detail is worth spelling out in the purchase order.
| Rule (examples) | Export declaration in Japan | Main carriage | Where risk passes |
|---|---|---|---|
| EXW | Buyer’s forwarder | Buyer arranges | Seller’s premises |
| FOB | Seller | Buyer arranges from the port | On board at the named port |
| FCA | Seller | Buyer arranges from the named place | At the named place |
| CIF | Seller | Seller arranges and pays | On board at the port of shipment |
Putting the sequence together
Fix the Incoterms rule and the certification route before the invoice is issued, and the rest of the file follows in order.
- Agree the Incoterms rule and who files the export declaration.
- Agree the invoice and packing list format with the seller, matched to what your own customs office expects.
- Decide whether any preferential origin claim applies, and if so, which certification system that specific agreement uses.
- Confirm the export is genuinely tax-exempt and keep the shipping evidence.
- File the export declaration in NACCS (the seller, its forwarder, or a customs broker) and receive export permission.
- Ship, and reconcile the documents on arrival against what was declared.

Frequently asked questions
1. Do I need a certificate of origin for every shipment from Japan?
No. A certificate of origin is only needed if your destination customs office requires proof of origin, or if you are claiming a preferential rate under a trade agreement. Ask which one applies before requesting a certificate.
2. Who files the export declaration in Japan?
Usually the Japanese seller, its freight forwarder, or a licensed customs broker, because the declaration must be filed in Japanese through NACCS, a system not accessible from outside Japan.
3. Why does my Japanese invoice show no consumption tax?
Because Japan treats a genuine export as outside the scope of consumption tax. The seller needs shipping evidence on file to support that treatment.
4. Can the exporter self-certify origin instead of using a chamber of commerce?
For agreements that allow first-party self-certification — including the Japan–Australia EPA, the CPTPP, the Japan–EU EPA and the Japan–UK agreement — yes. Other agreements still require a certificate from a designated issuing authority. Confirm which system the specific agreement uses.
5. Does the Incoterms rule decide who files the export declaration?
Not directly — Incoterms rules fix cost and risk, not paperwork responsibility. Confirm separately, in the purchase order, who handles the export declaration in Japan.
