Ecommerce in Japan: The Complete Guide for Foreign Brands (2026)

Japan’s B2C ecommerce market reached ¥26.1 trillion in 2024 (METI) — one of the largest in the world — and yet only 9.8% of Japanese retail happens online. That combination, huge and under-penetrated, is why ecommerce is the most common entry route for foreign brands into Japan. It is also a market with its own marketplace hierarchy, payment habits, service standards and import rules that trip up sellers who arrive with a US or European playbook.

This is our pillar guide to ecommerce in Japan: the market’s shape, the platforms and how to choose between them, payments, logistics, the rules for selling from abroad, and a phased plan. Detailed comparisons and platform deep-dives are linked throughout.

The Market in Numbers

Two takeaways for a foreign entrant. First, the market is mature enough that consumers have firm habits (marketplaces, points, payment methods) you must fit into rather than change. Second, the low EC ratio means online share keeps rising every year — the tailwind is structural.

The Platform Landscape

The big three marketplaces

• Amazon Japan (amazon.co.jp) — the largest ecommerce site by most estimates; search-driven, FBA logistics, English-language Seller Central. Lowest-friction entry for foreign brands. Professional plan ¥4,900/month plus mostly 5–15.4% referral fees.
• Rakuten Ichiba — the largest domestic marketplace: branded storefronts, the Rakuten Points loyalty ecosystem, event-driven buying. Higher fixed cost (¥60,000 registration, ¥25,000–¥65,000/month plans plus fees), stronger repeat purchase. Since September 2025, sellers in 13 countries can join without a Japanese entity.
• Yahoo! Shopping (LY Corporation) — the third pillar: over a million stores by Japanese industry counts, tightly integrated with PayPay and the Yahoo!/SoftBank ecosystem; lower fees, usually added after the first two.

Full breakdowns: Amazon Japan vs Rakuten.

Owned stores

Shopify is the default platform for foreign D2C brands building their own Japanese storefront: full brand control, margin and customer data, at the cost of generating your own traffic. Foreign merchants pair it with a local payment gateway (KOMOJU is common) for konbini, PayPay and bank transfer. When to add an owned store — and how it compares with a Rakuten storefront — is covered in Shopify vs Rakuten.

Cross-border and other channels

Cross-border ecommerce (shipping from abroad, often via marketplaces or specialist platforms) is a legitimate validation stage, hampered by delivery times, customs friction and returns. Mercari and other C2C apps are large but not brand channels. Category-specific marketplaces (ZOZOTOWN for fashion, @cosme for beauty) matter within their verticals.

Payments: Why Cards Aren’t Enough

Japanese checkout expectations differ from Western norms, and payment availability measurably changes conversion:

• Credit cards remain the leading online payment method.
• Konbini payment — paying for an online order at a convenience store — accounts for close to a fifth of online spending by some estimates and is especially common among younger and card-averse shoppers.
• PayPay passed 70 million registered users in July 2025 — more than one in two people in Japan — and dominates QR/wallet payments; it is integrated into Yahoo! Shopping and increasingly expected at checkout.
• Cash on delivery persists as a trust mechanism for first purchases from unfamiliar brands.
• Points ecosystems (Rakuten Points, PayPay, d POINT, V Points) shape platform choice — consumers concentrate purchases where they earn most.

Practical rule: on a marketplace, the platform handles this; on an owned store, add konbini and PayPay early. Details in Selling to Japan.

Logistics and Service Standards

• Delivery precision. Next-day or two-day delivery with selectable time windows is normal; late or vague delivery reads as unreliability. FBA and Rakuten Super Logistics exist precisely to meet this bar.
• Packaging. Damaged or careless packaging generates returns and negative reviews at rates that surprise foreign sellers.
• Japanese-language support. Prompt, polite support in native-level Japanese is the minimum. English-only support is the fastest route to bad marketplace reviews.
• Reviews compound. Japanese buyers read reviews heavily and write them critically; early operational excellence is marketing.

Selling From Abroad: The Rules That Matter

• Entity: not required to sell on Amazon Japan; not required for Rakuten if you’re in one of the 13 program countries (US, UK, Canada, Australia, Germany, China, Denmark, Belgium, Finland, New Zealand, Norway, Sweden, Switzerland); Shopify is available anywhere.
• Import: since October 2023, Japan Customs requires non-resident importers to appoint an Attorney for Customs Procedures (ACP). Amazon will not act as your Importer of Record — arrange an ACP/IOR service, distributor or your own entity before the first inbound shipment.
• Consumption tax: 10% standard rate; registration thresholds and the qualified-invoice system affect pricing and B2B relationships — get advice early.
• Category rules: food, cosmetics, electronics and supplements carry pre-market obligations (labeling, notifications, the PSE mark for electrical goods). Budget months for regulated categories.
• Consumer-law disclosures: ecommerce sites must display seller information under the Specified Commercial Transactions Act; marketplaces enforce this at onboarding.

One more from-abroad reality: your proceeds and your Japan-side costs flow through multiple currencies. The full payout mechanics are in our guide to getting paid as a foreign seller; for the multi-currency layer itself, we recommend Wise:

A Phased Plan for Foreign Brands

Phase 1 — Validate (months 1–3). Localize your best SKUs’ listings properly (native Japanese, not machine translation); launch on Amazon Japan with FBA after arranging an ACP; set up Japanese-language support; measure conversion and review sentiment. Cost is mostly variable.

Phase 2 — Expand (months 4–9). Add Rakuten Ichiba once demand is proven and Japanese-language operations are staffed; lean into points and sale events; start Japan-specific marketing (search, LINE) to build brand demand beyond marketplace search.

Phase 3 — Own (months 10+). Launch a localized Shopify store with local payments for margin, data and retention; add Yahoo! Shopping for incremental reach; evaluate a Japanese entity when banking, distribution or B2B credibility require it (see Doing Business in Japan).

Common Mistakes

1. Launching with translated, not localized, listings — then concluding Japan doesn’t convert.
2. Underestimating import mechanics — goods stuck at customs because no ACP was appointed.
3. Cards-only checkout on an owned store — leaving konbini/PayPay buyers on the table.
4. Treating Rakuten as a test channel — its fixed costs punish uncertainty; validate on Amazon first.
5. Western-minimal store design — Japanese shoppers expect information density, especially on Rakuten.

Tools

For the owned-store leg of the plan, Shopify is our default recommendation for foreign brands:
