This paper discusses how Japanese FamilyMart transferred its expertise and know-how to the Taiwanese market through these three stages with a focus on five-point critical success factors. This study’s research method uses survey analysis conducted via interviews with company executives and historical information collected from newspapers, magazines, and other secondary data. A combination of prior research and author own preliminary studies on the Japanese founded company suggests that a five-point summary explains FamilyMart’s critical success factors in the evolution of Japanese convenience stores: (1) The number of franchise stores exceeds corporate stores. (2) Sales for the ready-to-eat food category, such as the rice ball, are greater in Japan than in other countries. (3) The joint product distribution system with the manufacturer is crucial to operations. (4) The efficiency of chain management is enhanced by information systems.
