Isetan Shinjuku held its grand opening on March 6th. On March 8th, various events were held in the store, including a hospitality event. Many celebrities visited the store, often carrying large numbers of shoppers. Meanwhile, members of a famous idol group attended the "Prom Party" event at Jenny Fax Farm, held in the "TOKYO Kaihoku" area of the second-floor Center Park, which also attracted attention at the grand opening. They were seen browsing the products, caps pulled down over their eyes, reminiscent of the bustling young crowds on the second floor, once known as Cinderella City. The women's clothing section on the second floor, which was fully open, saw sales increase 300% year-on-year on the first day of the grand opening, 200% on the second and third days, and 120% above budget. Sales of Isetan Girl and Urban Closet were particularly strong, with significant foot traffic.
