7-Eleven Japan operates a highly efficient supply chain network to keep their convenience stores well-stocked. They use a combined distribution system where products from multiple suppliers are delivered to stores on shared trucks. This rapid replenishment policy ensures stores have a wide range of products available. 7-Eleven also uses an omni-channel strategy and IT systems like "item-by-item management" to closely match supply and demand. Their network design focuses on high population density areas for efficient distribution.
