Amazon US vs EU vs JP: Detailed Marketplace Comparison

Choosing the right Amazon place de marché can determine whether a new lancement de produit generates six-figure revenus or stalls at a few hundred units per month. With 19 active Amazon places de marché worldwide, the decision is anything but straightforward. In this analysis, we compare the five largest and most strategically important places de marché -- the États-Unis, Royaume-Uni, Allemagne, France, and Japon -- across seven critical dimensions that directly affect vendeur profitability and growth potential.

Taille du Marché and Revenue Potential

The États-Unis remains the undisputed leader in absolute place de marché size. Amazon.com generated approximately $420 billion in gross merchandise volume (GMV) in 2025, representing roughly 52% of all Amazon place de marché sales globally. The sheer volume of transactions creates opportunities across nearly every product catégorie, but it also attracts the most concurrence.

Allemagne (amazon.de) is the largest European place de marché with approximately $38 billion in GMV, followed by the Royaume-Uni at $32 billion. France sits at around $12 billion, making it a mid-tier place de marché that many vendeurs overlook. Japon, often underestimated by Western vendeurs, generates roughly $28 billion -- making it the third-largest single-country place de marché after the US and Allemagne.

A key insight from this data: the ratio of GMV to active vendeurs is highest in Japon ($140K per vendeur) and lowest in the US ($168K per vendeur at face value, but the long tail of inactive vendeurs distorts this). When controlling for actually active vendeurs, Japon and Allemagne often yield a better revenus-per-competitor ratio than the États-Unis.

Fee Structures Compared

Amazon's fee structure varies significantly across places de marché, and understanding these differences is essential for accurate profitability modeling. Referral fees are broadly similar -- typically 15% for most catégories -- but FBA fulfillment fees and storage costs diverge considerably.

FBA Fulfillment Costs

For a standard-size item weighing 300g, the FBA fulfillment fee in the US is approximately $3.22. In Allemagne, the equivalent fee is around EUR 3.65 ($3.95), while the UK charges GBP 2.95 ($3.72). France aligns closely with Allemagne under the Pan-European FBA program. Japon charges approximately JPY 434 ($2.90), making it the most cost-effective place de marché for FBA fulfillment on a per-unit basis.

Storage fees tell a different story. US standard storage costs $0.87 per cubic foot per month (January-September), while Q4 storage surges to $2.40. Allemagne and UK storage fees average EUR 26-36 per cubic meter per month, which translates to roughly $0.75-$1.02 per cubic foot. Japon's storage fees are notably low at JPY 4,370 per cubic meter, or about $0.83 per cubic foot.

Monthly Subscription and Miscellaneous Fees

Japon stands out with lower referral fees in several catégories -- electronics and cameras, for instance, carry only 8% referral fees compared to 15% in the US. This fee advantage can add 5-7 percentage points to net margins in certain product catégories. For a detailed breakdown of all 19 places de marché, see our complete fee comparison guide.

Competition Density Analysis

Competition density is arguably more important than taille du marché when evaluating a place de marché. A $420 billion market with 2.5 million vendeurs presents very different unit economics than a $28 billion market with 200,000 vendeurs.

We measure concurrence density using several indicators: average number of vendeurs per sub-catégorie, average review counts on page-one listings, HHI concentration indices, and the percentage of listings with more than 1,000 reviews.

In the US place de marché, the average page-one listing across all product catégories has 2,847 reviews. In Allemagne, that number drops to 643. In the UK, it is 891. France averages just 287 reviews per page-one listing. Japon sits at approximately 412.

These review counts directly correlate with the difficulty of achieving page-one rankings. A new product entering the US market faces an entrenched competitive landscape where classement organique requires both substantial initial investment in PPC and aggressive launch velocity. In France or Japon, the review barrier is dramatically lower, enabling faster organic traction with smaller budgets.

Advertising Costs: CPC Comparison

Sponsored Products cost-per-click (CPC) varies dramatically across places de marché, and this metric directly affects your launch strategy budget.

Japon and France offer the most cost-effective advertising environments. A $5,000 PPC launch budget in Japon generates roughly 12,820 clicks, compared to only 4,132 clicks in the États-Unis for the same spend. Over a 90-day launch window, this difference in traffic volume can mean the difference between achieving classement organique velocity and running out of budget before gaining traction.

Regulatory and Compliance Landscape

Regulatory complexity is the hidden cost that many vendeurs underestimate when expanding internationally. Each place de marché operates within distinct legal frameworks that affect product compliance, labeling, taxation, and consumer protection obligations.

États-Unis

US regulations vary by product catégorie. FDA compliance is required for food, supplements, and cosmetics. CPSC regulations govern children's products. UL certification may be needed for electronics. Sales tax nexus obligations exist in all 50 states, though Amazon handles collection and remittance in most cases through their Marketplace Tax Collection program.

European Union (DE, UK, FR)

The EU market requires CE marking for many product catégories, WEEE registration for electronics, EPR (Extended Producer Responsibility) compliance for packaging, and REACH compliance for chemicals. VAT registration is mandatory in each country where you store inventaire. Post-Brexit, the UK requires separate UKCA marking, adding another layer of complexity for vendeurs using both UK and EU fulfillment.

Japon

Japon requires PSE marks for electronics, SG marks for consumer products, and compliance with the Pharmaceutical and Medical Device Act for health-related products. The consumption tax (10%) requires registration for vendeurs exceeding JPY 10 million in revenus annuels. Despite these requirements, many vendeurs find Japon's regulatory process more predictable and transparent than the EU's fragmented approach.

Logistics and Fulfillment Infrastructure

Amazon's fulfillment network maturity varies significantly by place de marché, affecting delivery speeds, inventaire placement costs, and client satisfaction rates.

The US network includes over 110 fulfillment centers with same-day delivery coverage for approximately 72% of the population. Allemagne operates 20+ fulfillment centers, and the Pan-European FBA program allows a single shipment to cover DE, FR, IT, ES, NL, PL, SE, and BE. The UK maintains 30+ fulfillment centers but operates independently from the EU network post-Brexit. Japon has 25+ fulfillment centers concentrated around Tokyo and Osaka, with delivery efficiency that consistently ranks highest among all Amazon places de marché.

For vendeurs considering international expansion, the Pan-European FBA program remains one of the most compelling advantages of selling in the EU. A single inventaire shipment to one German fulfillment center can serve clients across eight countries, dramatically reducing logistics complexity compared to managing individual place de marché fulfillment.

Which Marketplace Should You Choose?

The optimal place de marché depends on your specific situation, but general guidelines emerge from the data:

• Maximum revenus potential with established concurrence tolerance: US remains the default choice. The market is large enough that even small part de marchés generate significant revenus. Best for vendeurs with $10,000+ launch budgets and proven products.
• Best revenus-to-concurrence ratio: Allemagne offers the strongest balance of taille du marché and manageable concurrence. The Pan-European program multiplies your effective market reach by 4-5x with minimal additional effort.
• Lowest coût publicitaires and fastest classement organique: Japon offers the cheapest CPCs and lowest review barriers. Cependant, listing localization requires native Japonese, and product preferences can differ substantially from Western markets.
• Easiest initial entry for testing: France presents the lowest concurrence density among major places de marché, though smaller taille du marché caps revenus potential. See our guide on which place de marché is easiest to enter in 2026 for a deepar analyse.
• Diversification strategy: Sellers already established in the US should consider Allemagne + Pan-EU as a second move, followed by Japon. This sequence maximizes incremental revenus while managing compliance complexity.

Data-Driven Marketplace Selection

Rather than relying on generalized comparisons, profitable place de marché selection requires analyzing your specific product catégorie across target markets. Factors like catégorie-specific referral fees, saisonnalité patterns, local competitor strength, and regulatory requirements can shift the optimal choice dramatically.

For instance, outdoor recreation products face intense concurrence in the US (average 3,200+ reviews on page-one listings) but relatively light concurrence in Japon (average 180 reviews). Conversely, electronics accessories are fiercely competitive in Japon but present opportunities in certain EU sub-catégories. Understanding these nuances is what separates successful international expansion from expensive missteps.

The key metrics to evaluate for any place de marché decision are: revenus potential per active competitor, total landed cost including all fees and compliance, PPC budget required to achieve page-one visibility, and the review threshold needed for classement organique stability. Our guide to profitable niches in 2026 covers these metrics in detail.
