Takashi Okutani, General Manager, WEB Business Division, Ryohin Keikaku CO., LTD. (Muji), said: "With the introduction of Muji Passport, we are now able to collect customers’ purchase trends and activity data including offline store data. In today's omni-channel age, we were looking for a tool which would centrally manage data from both Internet and physical stores and become a part of our marketing automation strategy that aims to serve our customers better.
“We decided to use the personalised recommendation tool proposed by Infosys with its excellent algorithm and accuracy. This implementation has enabled us to provide automatic recommendation of products via Muji Passport to customers who don’t have access to the online store, based on their purchase history in physical stores and across the omni-channel environment.

“We deeply appreciate Infosys, who has developed and implemented such an innovative system for the retail industry. Together with Infosys, we will continue to evolve this innovation to a more advanced stage. As a leading company in omni-channel age, we shall continue to provide the best information to the customers and deepen our mutual understanding."

They are using advanced analytics to better understand what their customers need and deliver it quickly. By integrating its e-commerce roadmap with InteractEdge, Muji can capture greater market share and make shopping a pleasure for its customers."
