Abstract The omnichannel varies across countries due to different retail environments and retailers’ growth strategies. The Japanese big retailers’ omnichannel can be characterized by having multiple retail formats, such as department stores, general merchandise stores, convenience stores, specialty stores, Internet stores, and so on. They have grown by multiplying retail formats to appeal to different customer segments, and they have unique challenges in managing an omnichannel with many retail formats. These are (1) extremely wide variety of merchandise, (2) enormous quantity of data from transaction, inventory, logistics, and customers, (3) different organization structures and management, and (4) unique organizational capabilities in each retail format. From these challenges, we could propose further research issues as follows: (1) theoretical consideration of boundary-spanning functions among retail formats, (2) international comparative analysis reflecting the different conditions in each country, and (3) clarifying the characteristics of the omnichannel shopper in the Japanese omnichannel environment.
