Rankings before the merger by store count:
Circle K-Sunkus 6,251
FamilyMart (Circle K-Sunkus) 18,123
However 1,000 of the Circle K-Sunkus stores will be closed or will be moved, due to business conditions or proximity to FamilyMart stores.
The final goal of the reorganization is to have all the stores branded as FamilyMart by February of 2019.
My thoughts: It will be sad to see Circle K-Sunkus go. As the 4th place player, they have always worked to provide very different selections and new ideas to compete with the big guys. Three dominant chains provides a degree of competition, but you can already see the selection at 7-Eleven becoming very predictable if not boring.
