How to sell on Amazon Japan from preparation to launch.

Why US brands sell on Amazon Japan.

Amazon's Japan expansion guide calls Japan one of the largest economies in the world, with many shoppers buying online. It also says many Japanese customers are used to high-quality advertising and convenient delivery. A brand that already sells on Amazon.com can add a Japan account, cross-list products with Build International Listings, and use FBA and Amazon Ads in Japan.

We recommend Amazon Japan as a first channel when the product sells on its specifications, the brand already runs Amazon operations, and the team can support Japanese listings, stock, and customer questions. It is a weaker first channel when the product needs heavy education, category approvals are still open, or no one can own the Japan account day to day. The same guide says the Amazon Japan team cannot support US-based sellers during expansion, though account-management support may be available after launch. Decide early who will help with setup.

When Amazon is one channel in a wider launch, we plan it as part of Japan market entry for US brands, next to import work, other sales channels, and paid media.

1. Choose the first product and account route.

Start with a small product shortlist. For each item, write down the Japanese customer problem, comparable offers, intended price, packed size and weight, and the questions a buyer would need answered before ordering. Use that work to decide which product deserves a first launch.

Amazon's US-to-Japan guide explains the account route: existing US Professional sellers can create a Japan selling account; new sellers planning to sell in both countries can start with a North America and Brazil unified account, then add Japan through Sell Globally. Confirm the route for your business before registering.

Prepare: a one-page product brief and a named account owner. If you are still choosing a channel, start with our guide to selling products in Japan.

2. Gather the account information before registration.

Amazon Japan's registration guide lists an email address, phone number, government-issued photo ID, a recent transaction statement, a chargeable credit card, and bank details for receiving proceeds among the account requirements.

• Business details: have the registered name, business location, registration number, and address ready.
• Account representative: prepare the person's identity details and clarify their relationship to the business.
• Payments: confirm the bank account holder and supported payout route; do not assume that a US payment setup transfers automatically.
• Verification: follow the document and identity-check prompts for your business type and country. Keep the submitted details consistent with the supporting records.

The identity-verification guidance includes different information for corporations and sole proprietors. Some examples concern Japanese entities; confirm the documents requested for your US entity in the registration flow. This preparation list does not guarantee account approval or a completion date.

3. Confirm product and import readiness.

Check the chosen product against Amazon Japan's category, safety, and listing requirements before committing stock. Amazon directs sellers to review Japan-specific compliance and tax requirements; a product sold in the US still needs a Japan review.

Ask the appropriate qualified specialists to confirm the product classification, applicable labels and approvals, importer arrangements, and tax treatment. Record who supplies the product evidence, who prepares the customs paperwork, and who can authorize shipment.

Japan Customs lists import-clearance documents including the invoice, transport document, packing list, and freight and insurance information; additional permits or origin documents may apply. Give your customs broker the product specifications and proposed shipment details so they can confirm the set needed for your goods.

4. Build a Japanese listing from verified product facts.

Amazon Japan's listing instructions distinguish adding an offer to an existing product page from creating a new one. Check for the exact product first. Prepare the product identifier or applicable exemption, brand and manufacturer information, category, title, images, description, price, stock, and shipping details. Complete any approval requested for the product.

• Source facts: collect dimensions, materials or ingredients, pack quantity, compatible uses, and approved claims in one brief.
• Japanese copy: have a qualified language reviewer check the title, feature bullets, description, image text, and customer instructions against that brief.
• Images: show the actual product and included items; check the current category and image rules before uploading.
• Final review: compare the rendered detail page with the product and packaging. Check units, variants, price, and delivery information before making the offer available.

Reuse verified US product facts, but review how they are presented in Japanese. Avoid adding claims merely because a competing listing uses them. Our guide on how to prepare an Amazon listing in Japanese works through a fictional product brief and a fact-to-field table.

5. Assign fulfillment, import, and support responsibilities.

Amazon describes two routes for Japan: send inventory to its fulfillment centers for FBA, or fulfill customer orders yourself. Amazon Japan's FBA service covers storage, picking, packing, shipping, and customer service and returns for FBA orders. Check the current product eligibility and preparation requirements before choosing it.

Treat customs clearance as a separate workstream. Japan Customs explains that the importer generally makes the declaration, with a customs broker able to act as proxy. Confirm the actual importer arrangement with your specialist; an FBA destination does not answer that question.

• Brand team: name the person responsible for stock decisions, product accuracy, pricing, and escalation.
• Import and logistics partners: agree the documents, clearance responsibilities, inbound delivery, and exception handling in writing.
• Customer operations: assign Japanese-language questions, returns outside the chosen service, product issues, and replenishment alerts.

For merchant fulfillment, confirm the delivery promise and returns process with the carrier or warehouse before publishing them. Keep a contact and backup contact for each task.

6. Estimate costs for the actual product and route.

Amazon Japan's pricing page and calculator cover selling-plan fees, category referral fees, fulfillment, and storage. Rates depend on the product and service; a single universal launch budget would hide those differences.

Keep one-time setup costs separate from per-order costs and ongoing overhead. Date each quote and record its assumptions. Compare the expected proceeds per order with the product, channel, delivery, and acquisition costs before deciding how much stock to commit.

7. Plan Amazon Ads once the offer is ready.

Amazon Japan's advertising page lists four types of sponsored ads that sellers set up themselves: Sponsored Products, Sponsored Brands, display ads, and streaming TV ads. Sponsored Products ads promote single listings in search results and on product detail pages, and Amazon suggests them for a first campaign. Sponsored Brands ads show a brand logo, a headline, an image, and up to three products. Most sponsored ads charge only when a shopper clicks.

Sponsored Brands, display, and streaming TV ads are open to Professional sellers enrolled in Amazon Brand Registry. Amazon Japan's seller guide says Brand Registry needs a registered or pending trademark, and that the Individual selling plan cannot use ads or promotions. The same guide names deals and coupons as other ways to promote a product.

Before starting an advertising test, inspect the customer-facing offer: correct product and variant, readable Japanese copy, available stock, delivery information, and a working support route. Set a spending limit and decide who can pause the campaign when an issue appears.

For the first review, put orders, ad spending, fees, stock, returns, and recurring customer questions together. Use the findings to choose the next correction. Sales volume alone is not enough to judge whether the launch economics work.

Common mistakes US sellers make on Amazon Japan.

Each mistake below skips a step earlier in this guide.

• Translating the US listing word for word. Start from verified product facts, then have a qualified reviewer check the Japanese title, bullets, images, units, and variants.
• Assuming FBA settles the import. FBA stores, packs, and ships orders. The importer, customs broker, and shipping documents still need named owners before stock leaves the US.
• Assuming the US payout setup carries over. Confirm the bank account holder and payout route for the Japan account during registration.
• Starting ads before the offer is ready. Check stock, delivery details, Japanese copy, and the support route first, then set a spending limit.
• Leaving Japanese customer questions unassigned. Name the person who answers questions and handles returns outside FBA before the listing goes live.

Our agency team for Japan launches runs these checks with the brand and brings in qualified specialists for regulated work.

A checklist for the launch meeting.

For each line, record the owner, evidence, and any open question. Use an unresolved item to decide what needs attention before launch.

• The first product and its intended customer are defined.
• The Japan seller account is verified and remaining account requests are resolved.
• Product, category, label, and import questions have been checked with the appropriate specialists.
• The Japanese listing matches the product facts, images, variants, and pack contents.
• The importer, broker, inbound delivery, fulfillment, and support responsibilities are agreed.
• Current fees and supplier quotes are recorded with assumptions and dates.
• The live offer, stock, price, delivery details, and customer support route have been reviewed.
• The launch budget, first review date, and person authorized to pause spending are agreed.
