What You’ll Learn

Japan has high AOV and stable repeat purchase, but Rakuten plays by rules that are nothing like Amazon JP’s.

After this module you’ll be able to:

• State the core differences between Rakuten and Amazon JP in traffic logic and store weighting
• Write listings with AI that match Japanese business writing conventions (keigo, structure, information density)
• Work Rakuten’s store-specific mechanics (Super SALE, points, store design)
• Complete the cross-border onboarding process

1. Rakuten vs Amazon JP Core Differences

2. Rakuten-Specific Operational Differences

2.1 Store-Page Customization

Rakuten’s biggest difference is that the store page can be fully customized (HTML/CSS), like a mini independent site:

• Brand-story page
• Product-category navigation
• Event-topic page
• Custom banner and visual design

AI application: use AI to generate Japanese store copy, event-page content, banner copy.

2.2 The Rakuten Points Ecosystem

Rakuten Points is one of Japan’s largest points ecosystems:

• Users earn points shopping on Rakuten, paying with a Rakuten Card, and booking hotels on Rakuten Travel
• Points can be used across the entire Rakuten ecosystem
• Sellers can set an extra points multiplier to attract users (like a discount but in points form)
• During Super Point Back events the points multiplier stacks, and traffic surges

2.3 R-Mail Email Marketing

Related reading: D1 Shopify — Shopify’s Klaviyo email-marketing methodology can be referenced in D1; the email-automation and personalization strategies are reusable for R-Mail.

Amazon prohibits sellers from directly contacting buyers, but Rakuten encourages it:

• R-Mail: sellers can email users who have purchased
• Email content: new-product notifications, promotions, points events, usage tutorials
• AI application: AI generates Japanese marketing emails, personalized recommendations, send-time optimization

R-Mail AI generation prompt:

You are a Rakuten email-marketing expert, proficient in Japanese business emails.

Store info:
- Store name: [name]
- Category: [X]
- The purpose of this email: [new-product notification/promotion/repurchase reminder/thanks]

Please generate an R-Mail email:
1. Email subject (≤50 characters, attract opens)
2. Email body (Japanese, desu/masu form)
- Opening: thanks + greeting
- Middle: core info (new product/promotion/recommendation)
- Ending: CTA + points reminder
3. Recommended send time (Japanese users' habits)
4. Personalization-variable suggestions (username, last-purchased product, etc.)

Note:
- Japanese consumers value politeness and detail
- The email shouldn't be too long (Japanese users prefer conciseness)
- Must include an unsubscribe link (required by Japanese law)
- Points-related info has the highest open rate

<copy_discipline>
- Never write a feature, material, certification, or result the product doesn't have. Any attribute I didn't state above must not appear in the copy
- For anything sent to a customer (replies, emails, templates), don't make commitments I haven't authorized: refund amounts, compensation, timelines, or exceptions to platform policy must be confirmed by me before they go in
- Flag any claim touching efficacy, safety, environmental, or patent language separately for manual review
</copy_discipline>

2.4 Event Mechanism

Real case: Rakuten × YouTube Shopping Japan launch On February 20, 2026, Google and Rakuten announced the launch of the YouTube Shopping service in Japan. While watching a YouTube video, users can press a button to show the product name and price on the screen, then jump to the Rakuten e-commerce platform for details (Japan Today). This is Japan’s first e-commerce platform to partner with YouTube Shopping, and creators can earn commissions by promoting Rakuten products.

2.5 YouTube Shopping × Rakuten (2026 New Feature)

Related reading: E2 YouTube AI Operations — the YouTube operations methodology is referenced in E2; the creator-collaboration and video-content strategies are directly reusable.

Please generate a complete Rakuten Japanese Listing:

1. Product name (Japanese, 80-120 characters)

- The Rakuten title can include 【】 and | separators
- Include search hot words

2. Catchphrase (キャッチコピー, 20-30 characters)

- Flag any claim touching efficacy, safety, environmental, or patent language separately so I can verify it by hand

4. Cross-Border Onboarding in Practice

4.1 Onboarding Paths

4.2 Onboarding Fees

5. Common Traps

5.1 Running Rakuten with an Amazon mindset

Rakuten is store-centric, not product-centric. Traffic goes to the store, not the individual item. Operating each SKU as a standalone listing forfeits the platform’s main traffic mechanism.

5.2 Machine-translating Japanese

Get the keigo level or the business register wrong and Japanese shoppers will simply read you as an untrustworthy merchant. This is where Japan differs most from other markets — “unnatural” copy is a hard failure here, not a minor blemish.

5.3 Skipping the points (ポイント) campaigns

Sitting out the points-multiplier campaigns during major sales means voluntarily exiting the sale traffic. Price the points cost in up front rather than deciding when the campaign arrives.

5.4 Under-investing in store design

The Rakuten store page carries most of the brand-trust weight. Ship with a default template and your conversion will sit visibly below comparable sellers.

When this doesn’t work

• Your Japanese is merely correct. This market is sensitive to honorific level, sentence rhythm and the handling of loanwords, and traces of machine translation cost you trust directly. It shows most in support replies — a wrong politeness level reads worse than no reply. A native speaker has to pass over the final text.
• You transplant Amazon’s shop and operating model. Shops here are merchant-operated: page structure, promotional mechanics and the points system follow a different logic from Amazon’s. Carrying an Amazon listing mindset across usually does not take, and the shop needs rebuilding on the platform’s own model.
• You apply standard cross-border aftersales. Japanese buyers generally expect more of packaging integrity, dispatch speed, documentation and response, and falling short shows up in reviews and is hard to recover. Confirm your fulfilment chain can reach that level consistently before entering, rather than listing first and finding out.
• Your volume does not support local operations. Local support, local returns and maintaining Japanese content are ongoing costs. At low volume, testing through Amazon JP first is usually safer than opening a second Japanese channel at the same time.
