Rakuten & Amazon Product Image Rules｜How to Meet White-Background Requirements Efficiently
Both Rakuten Ichiba and Amazon have clear rules for the first image on a product page (the main image). Images that don't comply can hurt your visibility in search results or trigger correction requests — and in a category like apparel, where listings multiply quickly, it's easy to be in violation without realizing it.
This article summarizes the key main-image rules on each marketplace, then looks at how to stay compliant at scale without turning every new product into a photo shoot.
Rakuten's image registration guidelines
Rakuten Ichiba sets guidelines for the first product image shown in search results. The three key points:
- Background: a white background, or a photographic background where the product is clearly the subject
- Text ratio: text elements must occupy 20% or less of the image
- Frames and decoration: no borders or decorative backgrounds
Images with large sale banners or flashy frames are best kept out of the first slot. The guidelines are updated from time to time, so check Rakuten's official pages (RMS guidelines) for the latest version.
Amazon's main image requirements
Amazon is stricter. The main requirements:
- Background: pure white (RGB 255,255,255)
- Product fill: the product must occupy at least 85% of the frame
- Prohibited: text, logos, watermarks, and composites of multiple images
- Size: at least 1,000px on the longest side to enable zoom; 1,600px or more recommended
Fashion categories add their own rules. Adult clothing generally must be shown on a model, while mannequins are not allowed; kids' and baby clothing is shot flat. That means preparing a "white background × on-model" image for every product. Details vary by category and change over time, so verify the current requirements in Seller Central before listing.
What happens if you don't comply
Non-compliant main images can be suppressed from search results or flagged for replacement. Because search visibility directly drives sales, preparing compliant images from the start is far less work than fixing them later.
Main image by the rules, secondary images for persuasion
Since the main image leaves little creative freedom, the second image onward is where you differentiate: worn looks, outfit examples, fabric close-ups, and shots that convey fit and size. Think of it as a division of roles — main image for compliance, secondary images for conversion.
Producing "white background × on-model" in-house with AI
The real challenge is sustaining this for every SKU. Booking a model and a white-background studio for each new product is too heavy for small and mid-sized shops.
With AI image generation like Sugata Studio, you can generate on-model images from a single product photo, with white-background output that fits Rakuten's and Amazon's main image rules. Consistent multi-angle generation (front, 45-degree, side, back) lets you prepare the main image and secondary images in one pass.
Summary
Rakuten's baseline is "white background, text under 20%, no decoration"; Amazon's is "pure white background, 85%+ product fill, adult apparel on a model." Compliance isn't a one-time task — it recurs with every new product. Building a workflow where compliant images can be produced in-house, in minutes, changes both your listing speed and your cost structure.
