The Trade Desk Activates 28M 7-Eleven Members’ Purchase Data for Ad Targeting in Japan

For digital marketers, data quality and signal freshness are the difference between a campaign that converts and one that wastes impressions. The Trade Desk’s new integration with SEVEN-ELEVEN JAPAN delivers access to deterministic, SKU-level purchase behavior at a scale rarely seen outside China and the US. With the Japenese ad market longing for actionable offline data, this launch equips brands to build audiences off actual convenience store trips—rounding out omnichannel strategies with a crucial missing link.

The Trade Desk (TTD) has announced the integration of purchase data from SEVEN-ELEVEN JAPAN (SEJ) into its programmatic advertising platform, a move that promises to reshape retail media in Japan. Effective immediately, all advertisers in Japan can activate audience segments built from the transaction histories of approximately 28 million 7-Eleven App members. This integration marks one of the first times that SEJ’s granular ID-POS data—covering up to one year of consumer purchase behavior—has been made available through a demand-side platform (DSP) for cross-channel digital activation, including OTT, CTV, audio, and display. The partnership underscores the growing importance of retail media networks (RMNs) globally, as platforms and retailers seek to monetize first-party data in a privacy-safe, consent-based manner.

The Trade Desk’s new integration with SEVEN-ELEVEN JAPAN delivers access to deterministic, SKU-level purchase behavior at a scale rarely seen outside China and the US.

Japan’s digital advertising market has long grappled with fragmented data ecosystems and operational complexity, limiting advertisers’ ability to execute precise, data-driven campaigns at scale. SEJ operates the nation’s largest convenience store chain with roughly 22,000 locations and 20 million daily visitors—a treasure trove of high-frequency, high-volume purchase signals. By connecting this data directly to The Trade Desk’s platform via API, the initiative addresses a persistent pain point: advertisers can now plan, activate, and optimize campaigns using refreshed retail data without the cumbersome manual processes that previously hindered data integration. The always-on audience segments, curated by advertiser needs, span demographics and high-demand purchase categories, enabling more relevant omnichannel targeting.

The competitive implications are significant. For The Trade Desk, this integration fortifies its position in the fast-growing retail media sector, where giants like Amazon, Walmart, and Rakuten have built walled-garden ecosystems. By opening up access to a key offline retailer’s data for programmatic activation on the open internet, TTD differentiates itself as a neutral, interoperable platform. Advertisers gain the ability to reach consumers based on actual purchase behavior rather than probabilistic proxies, potentially improving return on ad spend (ROAS) for CPG, beverage, and fast-moving consumer goods brands that rely heavily on convenience store distribution. For SEJ, this unlocks a new revenue stream from its data assets without compromising consumer privacy—assuming robust consent mechanisms are in place.
