Summit and Tomod's Shared Loyalty Program "ST Points" Launches with Integrated Member IDs- Enhancing service in food and health through data-driven marketing leveraging retail data -

Sumitomo Corporation (Head Office: Chiyoda-ku, Tokyo; Representative Director, President and Chief Executive Officer: Shingo Ueno) and LXIO, Inc. (Head Office: Chiyoda-ku, Tokyo; President: Naohisa Tateishi; hereinafter "LXIO"), a company newly established by Sumitomo Corporation to analyze and utilize retail data, will integrate the member IDs of Summit supermarkets and Tomod's drugstores. Through this integration, the companies will both enhance service levels in food and health through the launch of this new data-driven marketing business leveraging retail data.

As of October 1, 2025, the "ST Integrated Rewards Program" has been introduced, merging the loyalty programs of Summit and Tomod's under the Sumitomo Corporation Group. With this change, customers will be able to earn "ST Points" at both stores. In addition, both "ST Points" and chargeable "ST Electronic money" will be available to use for payment at both Summit and Tomod's. Moving forward, expansion to additional retail partners beyond Summit and Tomod's is also being considered, with the aim of making it easier and more convenient for customers to earn and redeem points for a wide range of everyday purchases.
By unifying the loyalty programs, purchase data previously managed separately by Summit and Tomod's will now be connected. This will provide a deeper understanding of each customer and allow for tailored services, such as product and service recommendations aligned with purchasing behavior and lifestyles.

The Sumitomo Corporation Group operates 124 Summit stores and 265 Tomod’s stores, generating more than 200 million customer interactions annually. In addition to purchase data rooted in the daily lives of five million members in the Tokyo metropolitan area – drawn from high-frequency shopping at supermarkets and drugstores in the food and health categories – the Group will also leverage qualitative insights gained through customer relationships. Together, these will form the foundation of a new business for manufacturers and retailers.

To maximize the value of integrated purchase data, the Group has developed a new business intelligence (BI) tool, "L’miere," to serve as a retail data analytics platform and enable advanced utilization of ID-POS data. Based on anonymized purchase data, the tool will support business planning by retailers and marketing strategy development by manufacturers. In the future, additional offerings will include cross-retailer purchase trend analysis and advanced analytics powered by generative AI. Using ID-POS data as a foundation, services – including customer research that capitalizes on Summit and Tomods' customer base and individual customer relationships, as well as retail media initiatives utilizing smartphone apps and pharmacy waiting room spaces will be deployed. These services will provide multifaceted marketing support for retail companies and manufacturers.

Looking ahead, Sumitomo Corporation and LXIO aim not only to deepen collaboration within the Sumitomo Corporation Group, including Summit and Tomod's, but also to form partnerships with external retailers, manufacturers and companies in industries beyond food and daily necessities. Through these efforts, the companies seek to create new business models.
By harnessing purchase data, Sumitomo Corporation will deliver services closely attuned to each individual customer while generating new value across the retail sector.
