Rakuten Ichiba Seller Registration Guide for Taiwan Brands

Rakuten Ichiba is Japan's largest domestic e-commerce marketplace with approximately 57,000 merchant stores and over 130 million registered members as of 2024. Unlike Amazon Japan's product-centric model, Rakuten Ichiba operates on a store-centric model -- each seller operates an independently branded store with full creative control over design, product presentation, and customer communication. This model creates stronger brand identity opportunities for Taiwan brands that invest in distinctive Japanese-language store design.

Rakuten processes approximately JPY 6.5 trillion (USD 43 billion) in annual merchandise sales, with health and beauty, food, fashion, and home goods as top categories. Taiwan brands have had particular success in health supplements, beauty (especially skincare with Made in Taiwan positioning), specialty food, and kitchenware. The Super Points loyalty system drives high repeat purchase rates -- Rakuten members earn points redeemable across the entire Rakuten ecosystem.

Average Rakuten Ichiba merchant fees are higher than Amazon Japan. Commission rates range from 2.0% to 4.5% of GMV depending on category, plus a system usage fee of JPY 19,500 to 100,000 per month depending on store plan, plus an annual registration fee of JPY 60,000. Total platform costs for an active Rakuten store typically range from 15 to 25% of gross revenue -- similar to Amazon Japan when all fees including PPC are factored.

Taiwan brands evaluating Rakuten vs Amazon Japan should understand their different strengths. Amazon Japan provides faster access to consumers via Prime shipping and lower operational setup burden. Rakuten provides stronger brand storytelling through full store design customisation and higher average order values driven by the points system. Many Taiwan brands run both marketplaces simultaneously with different positioning strategies.

Foreign companies from Taiwan can open a Rakuten Ichiba store directly without establishing a Japanese corporate entity, but must have a designated Japanese-speaking contact person and be able to ship orders to Japanese customers with correct customs documentation. The application process begins at RMS (Rakuten Merchant Server) and requires completion of the Merchant Registration Form in Japanese.

Required documentation for foreign company registration: company registration certificate (Taiwan business registration translated into Japanese by a certified translator), bank account information for JPY settlement payments, contact person details with Japanese language capability, and product category confirmation. Rakuten conducts a due diligence review and may request compliance documentation for regulated categories.

For product categories subject to Japanese regulations -- pharmaceuticals, quasi-drugs, dietary supplements with FFC notifications, and certain food products -- Rakuten requires proof of compliance before allowing listing. Taiwan brands in health and wellness categories should prepare Japanese-language compliance documentation (JHFA certification, FFC notification confirmation, ingredient test reports) before submitting the merchant application.

Rakuten Ichiba pays merchants in JPY via bank transfer on a monthly cycle, approximately 2 months after the sale date. Foreign sellers must hold a JPY bank account or use an international money transfer service. Some Taiwan brands use services like Payoneer or Wise for lower-cost JPY-to-TWD conversion.

Rakuten Ichiba stores are built using RMS (Rakuten Merchant Server). Each store has a dedicated storefront URL, fully customisable HTML/CSS store design pages, individual product listing pages, and integrated customer messaging tools. All store content must be in natural, grammatically correct Japanese. Engage a professional Japanese copywriter (cost JPY 50,000 to 200,000 for initial store setup) rather than relying on machine translation.

Rakuten product titles should be approximately 60 to 100 characters in Japanese, incorporating the primary product keyword, the brand name, key specifications (quantity, flavour, volume), and any certification marks. Rakuten's search algorithm considers product title keywords but also store performance metrics: sales volume, review count and rating, click-through rate, and promotional participation.

Product photography on Rakuten requires the main product image on a white background at least 780px x 780px. Rakuten allows multiple secondary images with lifestyle scenes, ingredient close-ups, and infographic images. Japanese health and beauty consumers expect detailed ingredient explanation images, usage instruction images, and size comparison images. Invest in Japanese-language infographic design for supporting images.

Rakuten's store review system is critical. Products with fewer than 10 reviews effectively do not appear in search results for competitive categories. The primary mechanism for generating early reviews is Rakuten's Gachi Review program, Super Sale participation, and direct customer communication via Rakuten's post-purchase email system. Target at least 20 reviews on flagship products before investing heavily in paid advertising.

Rakuten Super Points are the platform's loyalty currency. Merchants can contribute additional points during campaigns to increase product attractiveness. Contributing 5x points during a Rakuten Super Sale event costs approximately 5% of GMV but dramatically increases click-through rate and conversion during the event period.

Rakuten Super Sale occurs 4 times per year (March, June, September, December) and is the largest sales event on the platform. Some merchants report 5 to 15 times their normal daily GMV during peak Super Sale hours. Merchant participation requires meeting inventory stock requirements, committing discounts on designated products, and contributing to Rakuten's event advertising.

Rakuten RPP (Rakuten Promotion Platform) is the platform's paid advertising system, operating on a cost-per-click model with minimum bids of JPY 10 per click. RPP ads appear in Rakuten Ichiba search results and across the Rakuten ecosystem. Average CPCs in health and beauty categories range from JPY 30 to 120 (approximately USD 0.20 to 0.80). New store launches should allocate a minimum RPP budget of JPY 100,000 to 300,000 per month during the first 3 to 6 months.

Taiwan brands with interesting brand stories -- manufacturing heritage or unique cultural food products -- have succeeded in gaining coverage on Rakuten's editorial team's product feature columns, which drive significant traffic at zero paid media cost. Contact Rakuten's editorial team through your RMS Merchant Support contact to propose a brand story feature after your store has been operating for at least 3 months with positive review history.
