One corner of the 10th floor with have a nearly 150-square-meter cafe. The retail giant said in a statement that it was trying to reverse the trend of young customers “turning away from brick-and-mortar stores in favor of ecommerce.” Because Lotte’s store is near Konkuk University, 35 percent of its sales come from customers in their 20s and 30s - a much higher figure than at other branches. The company said it first realized the potential of VR attractions when it operated a small VR arcade in el CUBE’s Hongdae branch, western Seoul, from September 2017 to last March. The arcade was only 148 square meters, but there were queues of people waiting for as long as one hour to get in on weekends, the company said. It was particularly a success among customers in their teens and 20s. “A VR theme park is a new kind of attraction for a local department store,” said Yoo Hyeong-ju, who heads Lotte Department Store’s development team. “We’re expecting the arcade to extend the amount of time people will spend in the store, particularly customers in their 20s and 30s, as well as families.”
