Amazon US vs EU vs JP: Detailed Marketplace Comparison

Choosing the right Amazon mercato can determine whether a new lancio del prodotto generates six-figure ricavi or stalls at a few hundred units per month. With 19 active Amazon mercatos worldwide, the decision is anything but straightforward. In this analysis, we compare the five largest and most strategically important mercatos -- the Stati Uniti, Regno Unito, Germania, France, and Giappone -- across seven critical dimensions that directly affect venditore profitability and growth potential.

Dimensione del Mercato and Revenue Potential

The Stati Uniti remains the undisputed leader in absolute mercato size. Amazon.com generated approximately $420 billion in gross merchandise volume (GMV) in 2025, representing roughly 52% of all Amazon mercato sales globally. The sheer volume of transactions creates opportunities across nearly every product category, but it also attracts the most concorrenza.

Germania (amazon.de) is the largest European mercato with approximately $38 billion in GMV, followed by the Regno Unito at $32 billion. France sits at around $12 billion, making it a mid-tier mercato that many venditori overlook. Giappone, often underestimated by Western venditori, generates roughly $28 billion -- making it the third-largest single-country mercato after the US and Germania.

A key insight from this data: the ratio of GMV to active venditori is highest in Giappone ($140K per venditore) and lowest in the US ($168K per venditore at face value, but the long tail of inactive venditori distorts this). When controlling for actually active venditori, Giappone and Germania often yield a better ricavi-per-competitor ratio than the Stati Uniti.

Fee Structures Compared

Amazon's fee structure varies significantly across mercatos, and understanding these differences is essential for accurate profitability modeling. Referral fees are broadly similar -- typically 15% for most categories -- 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 Germania, the equivalent fee is around EUR 3.65 ($3.95), while the UK charges GBP 2.95 ($3.72). France aligns closely with Germania under the Pan-European FBA program. Giappone charges approximately JPY 434 ($2.90), making it the most cost-effective mercato 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. Germania and UK storage fees average EUR 26-36 per cubic meter per month, which translates to roughly $0.75-$1.02 per cubic foot. Giappone'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

Giappone stands out with lower referral fees in several categories -- 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 categories. For a detailed breakdown of all 19 mercatos, see our complete fee comparison guide.

Competition Density Analysis

Competition density is arguably more important than market size when evaluating a mercato. A $420 billion market with 2.5 million venditori presents very different unit economics than a $28 billion market with 200,000 venditori.

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

In the US mercato, the average page-one listing across all product categories has 2,847 reviews. In Germania, that number drops to 643. In the UK, it is 891. France averages just 287 reviews per page-one listing. Giappone 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 organic ranking requires both substantial initial investment in PPC and aggressive launch velocity. In France or Giappone, 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 mercatos, and this metric directly affects your launch strategy budget.

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

Regulatory and Compliance Landscape

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

Stati Uniti

US regulations vary by product category. 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 categories, 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 inventario. Post-Brexit, the UK requires separate UKCA marking, adding another layer of complexity for venditori using both UK and EU fulfillment.

Giappone

Giappone 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 venditori exceeding JPY 10 million in annual ricavi. Despite these requirements, many venditori find Giappone'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 mercato, affecting delivery speeds, inventario placement costs, and cliente satisfaction rates.

The US network includes over 110 fulfillment centers with same-day delivery coverage for approximately 72% of the population. Germania 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. Giappone has 25+ fulfillment centers concentrated around Tokyo and Osaka, with delivery efficiency that consistently ranks highest among all Amazon mercatos.

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

Which Marketplace Should You Choose?

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

• Maximum ricavi potential with established concorrenza tolerance: US remains the default choice. The market is large enough that even small market shares generate significant ricavi. Best for venditori with $10,000+ launch budgets and proven products.
• Best ricavi-to-concorrenza ratio: Germania offers the strongest balance of market size and manageable concorrenza. The Pan-European program multiplies your effective market reach by 4-5x with minimal additional effort.
• Lowest advertising costs and fastest organic ranking: Giappone offers the cheapest CPCs and lowest review barriers. Tuttavia, listing localization requires native Giapponeese, and product preferences can differ substantially from Western markets.
• Easiest initial entry for testing: France presents the lowest concorrenza density among major mercatos, though smaller market size caps ricavi potential. See our guide on which mercato is easiest to enter in 2026 for a deeper analisi.
• Diversification strategy: Sellers already established in the US should consider Germania + Pan-EU as a second move, followed by Giappone. This sequence maximizes incremental ricavi while managing compliance complexity.

Data-Driven Marketplace Selection

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

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

The key metrics to evaluate for any mercato decision are: ricavi 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 organic ranking stability. Our guide to profitable niches in 2026 covers these metrics in detail.
