Toys R Us plans to withdraw from store operations in Japan by selling its business to Pan Pacific International Holdings, the operator of the Don Quijote discount chain, a person familiar with the matter said Tuesday. Toys R Us Japan has about 150 stores and employs roughly 6,000 people, including part-time workers. The Kawasaki-based subsidiary is owned by Toys R Us Asia and has reported losses in recent years, official gazettes show. Its business has been affected by Japan's declining birth rate, a shrinking child population and the growing use of online shopping. The first Toys R Us store in Japan opened in 1991. The original U.S. operator, which launched the brand in 1948, filed for bankruptcy protection in 2017, while the Japanese business continued operating. Pan Pacific International Holdings declined to comment.
