Rakuten Ichiba product data API

ShopAPIS extracts structured product data from Rakuten Ichiba — Japan’s largest B2C marketplace — and returns it as clean JSON. For any Rakuten listing you get item title, price, Rakuten Points / reward rate, JAN barcode, shop (店舗) identity, category taxonomy, rating, review count and the image gallery, normalized into one schema and enriched beyond what the official API alone returns.

Rakuten Ichiba runs roughly ¥6.1 trillion in annual GMV with ~44M members in the Rakuten ecosystem and an estimated ~495M monthly visits (plan2 research). Together with Amazon JP and Yahoo! Shopping it forms Japan’s top three, which hold ~55–60% of consumer GMV.

Official API and where ShopAPIS adds value

Rakuten provides an official Rakuten Web Service (Ichiba Item Search API). It is the cleanest, lowest-cost path for catalog and price fields and ShopAPIS uses it where it fits — but it is rate-limited, returns a constrained field set and does not give consistent multi-shop or cross-marketplace normalization. ShopAPIS layers parsed shop-level detail, review data and points logic on top, and returns Rakuten in the same schema as Amazon JP and Korea’s marketplaces so you can compare like-for-like (Rakuten Web Service ).

Data fields returned

• Identity — item code, title, JAN/EAN barcode, brand, category path
• Price — current price, list price, tax-included flag, currency (JPY)
• Rewards — Rakuten Points rate, points earned, SPU campaign flags
• Shop — shop name, shop code, shop rating
• Availability — in-stock flag, stock status
• Reviews — review count, average rating, review text
• Media — image gallery
• Logistics — shipping fee, free-shipping flag, delivery estimate
