Importing into Japan means lodging an import declaration with Japan Customs, usually through the NACCS cargo system, and receiving an import permit once the goods have been examined (where required) and the duty and consumption tax have been paid. The importer is responsible for the declaration, but a licensed customs broker normally files it as the importer's proxy. The two things that surprise first-time importers are that the 10% consumption tax is charged on the customs value plus the duty, and that the rules for food, plants, animals and electrical goods sit with other agencies, not Customs. This guide follows the order of a typical shipment. For the general process that applies in any country, start with our customs clearance guide. Rates and procedures below were checked against Japan Customs' English pages in October 2026 and can change.
How does import clearance in Japan work?
Japan Customs' English FAQ describes the sequence in plain terms: the importer lodges a declaration, Customs examines the declaration and, where needed, the goods, duty and consumption tax are paid, and Customs issues the import permit. Goods generally cannot leave the bonded area (called a Hozei area) until that permit exists. The declaration is usually made after the cargo has been brought into a bonded area, though Customs allows earlier declaration for specific cases.
Most of this runs through NACCS (Nippon Automated Cargo and Port Consolidated System), the online system operated by NACCS Inc. According to NACCS, it covers imports from vessel or aircraft arrival through unloading, import declaration and permission, and delivery inside Japan, and its users include importers, brokers, shipping lines and NVOCCs. Japan Customs states that more than 90 percent of import procedures are computerised.
Who files the declaration?
Customs' payment FAQ says that for general cargo the name, quantity, tax base and duty must be declared by the importer, and that a licensed customs broker can handle the declaration on the importer's behalf. In practice, most importers use a broker or a forwarder with in-house brokerage. If you are unsure whether to file yourself, see Do You Need a Customs Broker?
The import permit is not a licence you apply for in advance
A common misunderstanding is that an "import permit" is something an importer must obtain before ordering goods, as with an import licence in some countries. For ordinary commercial goods in Japan, the import permit is the customs release document issued at the end of clearance, after declaration, any examination and payment. Separate permits, approvals or notifications can be required beforehand for specific goods (covered below), and Customs asks for evidence of those with the declaration.
What documents does Japan Customs ask for?
Customs' FAQ on documents lists the standard set as the invoice, the bill of lading, sea waybill or air waybill, the insurance certificate, the freight account, the packing list, contracts and price lists. Conditional documents include permits or approvals under other laws (the FAQ gives the Plant Protection Law as an example), certificates of origin where a preferential rate is claimed, and a statement where a duty reduction or exemption applies. Customs may ask for more.
How is customs value worked out (CIF basis)?
Japan follows the WTO Valuation Agreement. The primary method is the transaction value: the price actually paid or payable, adjusted for certain items. Under Article 4 of the Customs Tariff Law, as summarised by Japan Customs, the adjustments include transport and insurance costs up to the port of importation, buyer-paid commissions (other than buying commissions), packing and container costs, assists supplied free or at reduced cost, royalties and licence fees that are a condition of sale, and resale proceeds that accrue to the seller. Costs after importation, such as installation and transport inside Japan, are excluded when they are clearly identified.
The practical effect is a CIF-style value: goods plus freight and insurance to the Japanese port. That is why the Incoterm in your sales contract matters. Under FOB, the freight and insurance you pay separately must still be added for customs. If the transaction value cannot be used, Customs falls back through identical goods, similar goods, deductive and computed methods, and a final fallback method. For the general mechanics, see Customs Valuation Explained.
How are duty and the 10% consumption tax calculated?
Two charges sit on most imports: customs duty at the rate in the Customs Tariff Schedule for the goods' classification, and consumption tax. Japan Customs lists the standard consumption tax as 10% in total, made up of 7.8% national consumption tax and 2.2% local consumption tax, where the local portion equals 22/78 of the national amount. A reduced rate of 8% (6.24% national plus 1.76% local) exists for certain goods, such as food and drink. Some goods also carry excise-type taxes (for example liquor or tobacco), which Customs collects separately.
Japan Customs' declaration form guidance and worked examples apply consumption tax to the customs value plus the duty, so you are taxed on duty. Each calculation step involves rounding rules, so a real declaration will differ by small amounts from the illustration below.
| Step | Illustration (JPY) |
|---|---|
| Customs value (goods plus freight and insurance to the port) | 1,000,000 |
| Customs duty at an assumed 5% | 50,000 |
| Consumption tax base (value plus duty) | 1,050,000 |
| National consumption tax at 7.8% | 81,900 |
| Local consumption tax (22/78 of the national amount) | 23,100 |
| Total payable at clearance | 155,000 |
The 5% duty rate is an assumption for the example, not a rate for any product. Duty can range from zero upward depending on the classification and any preferential treatment. A GST or VAT-style tax charged at the border is not a duty in the strict sense, but you should still budget for it as cash due at clearance. Whether a registered business can later recover the consumption tax depends on Japan's domestic consumption tax rules, so confirm that with a tax adviser.
How is payment made?
Under self-assessment, duty and consumption tax are paid at a bank or post office against a payment statement submitted with the declaration, or by the NACCS real-time account-transfer method. Duty payment can also be deferred with collateral under a separate scheme (Customs FAQ 1302). Small mailed parcels follow a different, official-assessment route through Japan Post.
How do I classify goods and get an advance ruling?
Duty depends on classification under the Customs Tariff Schedule, which Japan Customs publishes in versions by effective date and which builds on the Harmonized System. If you have not classified your product, read HS Codes Explained first.
Japan offers an advance classification ruling. According to Japan Customs, you can ask in writing (Customs form C-1000) for the tariff code and duty rate before importing. The written response paper is valid for three years and is respected at examination when attached to the declaration. It becomes void if the goods differ from the description, it has expired, the law has changed, or it contained an error. Oral and, in principle, email answers are for reference only. A request to review a written ruling must be made within two months.
How do I claim preferential duty under EPA, RCEP or CPTPP?
Preferential rates under Japan's economic partnership agreements are not automatic. The importer must show the goods originate, and the method depends on the agreement. Japan Customs' guidance describes three broad routes across its agreements: a certificate issued by the exporting country's authority, an origin declaration on a commercial document by an approved exporter, or a self-certification by the importer, exporter or producer. For CPTPP, Japan Customs says self-certification is the only route. For RCEP, its guide lists importer self-certification as available for all parties, with a declaration of origin and an attachment, and some additional options for Australia and New Zealand. Because the details differ by agreement and by goods, check the specific agreement page before you rely on a claim.
The importer stays responsible for origin and must keep supporting documents available if Customs asks. For the underlying logic, see Rules of Origin.
What is pre-arrival examination?
Japan lets declarations be lodged before cargo arrives so that Customs can do its document examination early and release faster. The exact filing window has changed over the years and published figures vary, so confirm it with your broker or the regional Customs office. One recent change is worth knowing: a Customs notice indicates that, for pre-arrival manifest declarations, notice of whether an inspection will happen is now given only after the formal import declaration, with exceptions for AEO importers and AEO customs brokers. Customs said it was tightening this after misuse of early notices. This detail comes from a summary of the notice rather than its full text, so ask your broker how it affects your timeline.
Which other agencies can control the import?
Customs enforces other laws at the border, and for regulated goods the other agency's requirement comes first. Japan Customs' own page says certificates under other laws must be submitted where an import is restricted. The main ones for commercial cargo, confirmed from each agency's English pages, are:
| Goods | Agency and requirement |
|---|---|
| Food, additives, apparatus, containers, packaging, toys for infants | Ministry of Health, Labour and Welfare: import notification under Article 27 of the Food Sanitation Act for goods imported for sale or business use, with document review and possible inspection |
| Plants and plant products | MAFF Plant Protection Station: import inspection, normally with the exporting government's phytosanitary certificate; some plants are prohibited |
| Animals, meat, bone, hides and other animal products | MAFF Animal Quarantine Service: notification and inspection, with bans or suspensions for outbreak regions |
| Electrical appliances and materials | METI: under the Electrical Appliances and Materials Safety Act, the importer notifies its business (within 30 days of starting) and must meet PSE labelling obligations before sale |
The PSE rules are a sales and labelling obligation on the importer, so do not assume Customs will stop a non-compliant shipment at the border. This table is a starting point, not a full list: chemicals, medical devices, cosmetics, wildlife and weapons all have their own regimes.
What is Japan's AEO and Authorized Importer system?
Japan runs an AEO programme under the WCO SAFE Framework, with categories for importers, exporters, warehouse operators, customs brokers and logistics operators. Under the Authorized Importers' Program, according to Customs' FAQ, an approved importer can have goods released on a declaration of 19 items instead of 55 for an ordinary declaration, without stating the tax base and amount at release, with examinations reduced to reflect its compliance record. It then files a duty payment declaration monthly, due by the end of the following month. Missing that deadline without good reason can lead to revocation. Approval criteria are not on the FAQ page, so ask Customs. Japan also has mutual recognition arrangements with several economies; check the current list. For the wider picture, read AEO and CTPAT Explained.
Small shipments and online orders
Japan Customs has a simplified procedure for qualifying small sea cargo from online orders, available only to sea cargo customs brokers, where the total customs value is 10,000 yen or less and the shipment meets conditions including no other-law certification. Customs also pays attention to the 200,000 yen line for mail: above it the importer must self-declare. Thresholds of this kind are reviewed by governments from time to time, so check the current figure before planning a low-value flow.
What to do next
- Classify the product and, if duty matters to your margin, request a written advance classification ruling (form C-1000) before the first shipment.
- Check whether the goods fall under the food, plant, animal or electrical rules, and complete that notification or inspection step before arrival.
- Work out the customs value on a CIF basis, add duty, then apply 7.8% plus the 22/78 local portion to budget the cash due at clearance.
- Confirm which origin document your agreement accepts, and agree with your broker how and when the NACCS declaration will be filed.
