What Is Amazon Japan (Amazon.co.jp)?
Amazon Japan, operating at amazon.co.jp, is the largest online marketplace in Japan by gross merchandise value, accounting for an estimated 20–25% of all Japanese e-commerce sales. Since its launch in November 2000, Amazon Japan has grown into a platform trusted by more than 100 million registered users for daily purchases — from electronics and fashion to groceries, beauty, and specialty imports.
For international brands, Amazon Japan is frequently the first step into the Japanese market: no Japanese legal entity is required to open a seller account, the fulfillment infrastructure (FBA Japan) eliminates the need to build local logistics from scratch, and the platform's discovery engine is already familiar to the shoppers you need to reach.
This guide covers everything an overseas brand needs to know to sell on Amazon Japan successfully — from account setup and product listing optimization, through FBA operations, advertising, and regulatory compliance.
Why Amazon Japan Is Worth Your Attention
Japan is the world's fourth-largest e-commerce market
Japan's online retail market exceeds $160 billion USD in annual gross merchandise value, making it one of the most valuable e-commerce destinations outside of China and the United States. Growth continues at approximately 8–10% per year, driven by an aging population increasingly comfortable with online shopping and a logistics infrastructure — same-day and next-day delivery nationwide — that makes e-commerce frictionless.
Japanese consumers also have exceptionally high purchasing power. Average order values on Amazon Japan are significantly higher than comparable categories in many Western markets, and Japanese shoppers willingly pay premiums for products they perceive as authentic, high-quality, or internationally recognized.
Low foreign competition, high opportunity
Despite Japan's market size, most international brands have not built a serious presence on Amazon Japan. The language barrier, compliance requirements, and unfamiliarity with Japanese consumer behavior have created a gap that well-prepared overseas brands can fill. For niche categories — specialty food, premium outdoor gear, independent beauty, professional tools — competition from other international brands on Amazon Japan is often minimal.
Step 1: Opening a Seller Account on Amazon Japan
Professional vs. Individual accounts
Amazon Japan offers two account types. The Individual plan charges a per-item fee with no monthly subscription but lacks advertising tools, Buy Box eligibility, and bulk listing features. The Professional plan costs ¥4,900 per month (~$32 USD) and provides full access to all seller tools, including Sponsored Products advertising, A+ Content (via Brand Registry), and bulk inventory uploads. Every international brand should start with a Professional account.
Documents and requirements for international sellers
- Business registration or incorporation document from your home country
- Business bank account — Amazon pays via international wire transfer; Payoneer or World First are commonly used to receive payments in your preferred currency
- Credit or debit card for account billing
- Government-issued ID (passport or driver's license)
- Phone number for SMS or call verification
No Japanese address, Japanese bank account, or Japanese entity is required to start. However, once annual Japan sales exceed ¥10 million, you will need to register for Japanese consumption tax under the Invoice System (インボイス制度) and obtain a qualified invoice issuer number. Most growing brands hit this threshold within their first two years.
Step 2: Creating High-Converting Product Listings
Japanese-language listings are mandatory
Amazon.co.jp requires all listings to be in Japanese. Listings with English titles or descriptions are routinely suppressed or removed. More importantly, Japanese consumers are highly attuned to translation quality — machine-translated content is immediately recognizable and erodes conversion rates and review scores.
Invest in professional Japanese e-commerce copywriting for every key listing element:
- Product title — up to 500 characters; include primary keyword, brand name, and key specifications
- Bullet points — 5 points, each up to 150 characters; emphasize benefits in a style natural to Japanese copywriting
- Product description / A+ Content — Japanese consumers read full descriptions before purchasing
- Backend search terms — Japanese only; include hiragana, katakana, and kanji variations of the same concept, as Japanese search queries vary significantly in script form
Amazon Brand Registry Japan
Enrolling in Amazon Brand Registry is one of the highest-ROI actions for any international brand on Amazon Japan. It requires a registered trademark in Japan (filed with the Japan Patent Office — JPO), which takes 12–18 months to grant. Plan and file early.
Brand Registry unlocks A+ Content, Amazon Brand Stores, Sponsored Brands and Sponsored Display advertising formats, counterfeit protection and listing ownership enforcement, and Brand Analytics — search term reports, market basket analysis, and demographic data.
Product images
Amazon Japan's technical image requirements mirror global standards (white background for main image, minimum 1,000 pixels). Supplementary infographic-style images perform exceptionally well with Japanese shoppers, who appreciate organized, detail-rich visuals. Dimension charts using metric units and Japanese size equivalents are especially important for apparel, footwear, and accessories. Lifestyle images featuring Japanese environments or models typically outperform Western-market photography in Japan-specific A/B tests.
Step 3: Fulfillment by Amazon (FBA) Japan
Why FBA is essential for most categories
FBA Japan stores your inventory in Amazon's Japanese fulfillment centers (primarily in Chiba, Osaka, and Nagoya) and handles all picking, packing, shipping, returns, and Japanese-language customer service on your behalf. For most consumer goods categories, Prime eligibility — only available through FBA or the rarely-granted Seller Fulfilled Prime — is effectively mandatory. Japanese shoppers expect same-day or next-day delivery as the baseline, not a premium service.
Shipping inventory to Japan FBA
- Importer of record: You (or your appointed agent) are responsible for customs clearance, import duties, and consumption tax at entry
- Product compliance: Products must meet Japanese technical standards before importing or listing (see Step 5)
- Freight options: Sea freight costs ~$0.50–$2.00/kg but takes 4–6 weeks; air freight arrives in 3–7 days at 4–6× the sea freight cost per kg
- Inventory planning: Maintain 6–10 weeks of cover at FBA Japan to allow for sea freight replenishment cycles
Working with a Japan-based customs broker (通関業者) simplifies import documentation significantly and is strongly recommended for first-time shippers to Japan.
Step 4: Amazon Japan Advertising
Sponsored Products
Sponsored Products is the foundational advertising format — keyword-triggered cost-per-click (CPC) ads that appear in search results and on product detail pages. For a new listing, Sponsored Products is typically the primary driver of early sales velocity, which builds organic search rank. Amazon Japan CPCs range from ¥30 to ¥150 for most consumer goods categories, rising to ¥200–¥500+ in competitive segments like beauty, supplements, and electronics.
Sponsored Brands
Available to Brand Registry sellers, Sponsored Brands appear as banner units at the top of search results. They link to a Brand Store or curated product page and are effective for increasing brand-level awareness, particularly for category-new shoppers.
Promotions and deals
Japanese Amazon shoppers are highly responsive to visible price promotions. Lightning Deals, Coupons (クーポン), and Prime Day exclusives all drive significant incremental volume. A well-executed Prime Day promotion on Amazon Japan can generate 5–10× a typical day's sales. Plan inventory and advertising budgets around Amazon Japan's promotional calendar: Prime Day (July), Black Friday (November), and the year-end sale (December).

Step 5: Product Compliance in Japan
Japan enforces strict product safety and labeling regulations that international sellers must satisfy before importing or listing products:
- Electronics (PSE mark — 電気用品安全法): Electrical appliances require PSE certification. Class A products need third-party inspection; Class B requires self-certification with testing records.
- Food and beverages (食品衛生法): Import notification to local health authorities required. All labels must be in Japanese and meet content requirements (ingredients, allergens, net weight, importer name and address).
- Cosmetics (薬機法): Standard cosmetics require Japanese-language labeling and an importer notification. Quasi-drug cosmetics (medicated claims) require PMDA approval.
- Textiles: Household Goods Quality Labeling Act requires Japanese care labels and fiber composition disclosure for all clothing and textiles.
- Toys (ST安全基準): Children's toys must comply with ST safety standards.
Most international brands appoint a Japan-based importer of record (輸入代行業者) who holds the required import licenses and handles compliance documentation on their behalf.
Five Mistakes International Brands Make on Amazon Japan
- Launching with machine-translated listings. The quality difference is visible to every Japanese shopper and destroys conversion rates regardless of how good the product is.
- Skipping Brand Registry. Without a Japanese trademark, competitors can list under your brand name. The 12–18 month trademark process makes filing early non-optional.
- Underestimating review velocity requirements. Products with fewer than 50 reviews are treated with skepticism. Build reviews systematically via Amazon's Request a Review tool and Vine enrollment for new products.
- Pricing based on home-market economics. The all-in cost to serve a Japanese customer — international freight, import duty, FBA fees, and Amazon's referral fee — often requires a 2–3× markup on production cost to achieve acceptable margins.
- Ignoring seasonal promotions. Brands that don't prepare inventory and advertising for Prime Day and year-end sales miss their largest annual revenue windows.
