1. 2026 EC Market Overview: Positioning of Rakuten and Amazon
As of 2026, the Japanese EC market is transitioning from the maturity phase to the phase of "automatic purchase by AI agents" and "hyper-personalization." Rakuten is aiming for a further deepening of the "Rakuten Ecosystem" (economic block) and maintains a high LTV (Customer Lifetime Value) by maximizing synergy with FinTech and mobile businesses. In particular, promoting cross-usage among mobile users through "Saikyo Plan" forms a solid retention loop.
In contrast, Amazon has pushed the efficiency of its self-contained logistics network (FBA) to the limit and increased last-mile delivery density to expand same-day delivery areas to a nationwide scale. Additionally, through advanced attribution analysis leveraging the "Amazon Marketing Cloud (AMC)," it has dramatically improved the advertising ROI for manufacturing companies. This has become a decisive advantage in the cookieless era.
2. Thorough Comparison of GMV Growth Rate and Market Share
The metric EC managers should pay the most attention to is the growth speed of each mall. Based on forecast data for 2026, while the Gross Merchandise Volumes of both are balancing out, differences can be seen in the quality of growth. Rakuten is characterized by explosive sales driven by events such as the "Shopping Marathon" and "Super SALE," while Amazon's strength lies in its steady, subscription-like growth due to "Subscribe & Save."

A major change in 2026 is that Amazon has reached a level where it is competing by a narrow margin for the top spot in domestic GMV share. This is contributed to by the spread of "Amazon Subscribe and Save" for daily necessities and the rapid growth of "Amazon Business" aimed at corporations. On the other hand, Rakuten is expanding its unique economic block by strengthening cooperation with local governments, using its overwhelming position as a platform for "Furusato Nozei" (Hometown Tax Donation) as a weapon.
3. Platform-specific Operational Strategies Required in 2026
When thinking about the "Rakuten vs Amazon Comparison 2026," it is also necessary to update specific methods for store operation. On Rakuten, creating unique "fans" for a store is considered even more important. CVR improvement measures through UGC (User Generated Content) utilizing R-SNS and Rakuten ROOM have become essential, and providing "emotional value" rather than mere price competition is required.
On the other hand, for Amazon, one must adapt to the complete transition from the "A9/A10 algorithm" to "Semantic Search" integrating LLM (Large Language Models). It is not keyword stuffing, but rather the accuracy of the answer to the user's search intent that dictates rankings. In addition, an approach through the full funnel using Amazon DSP has become established as the winning pattern in 2026.
