Established in 1973, Seven-Eleven Japan set up its first store in Koto-ku, Tokyo, in may 1974.

Supply chain Performance Drivers for Seven-Eleven Japan:
Facilities: Focus: High Efficiency with adequate responsiveness.
To ensure efficiency, Seven-Eleven Japan based its fundamental network expansion policy on a market-dominance strategy. Entry into any new market was built around a cluster of 50 to 60 stores supported by a distribution center. Such clustering gave Seven-Eleven Japan a high-density market presence and allowed it to operate an efficient distribution system. This also increased its proximity with customers resulting in increased responsiveness.
Also, processed food and fast-food items were big sellers for the stores. In 2004, processed and fast foods contributed about 60 percent of the total sales at each stores.

The key to store delivery is what Seven-Eleven calls the Combined Delivery System. At the distribution center, delivery of like products from different suppliers (for example milk and sandwiches) is directed into a single temperature controlled truck. There are four categories of temperature controlled trucks: frozen foods , chilled foods, room...
