Carlyle, which said KFC Holdings Japan has not realized its full potential, plans to speedily open more outlets and add new menu items to enhance its corporate value. The investment fund is expected to turn the company into a wholly owned subsidiary. KFC's Japanese operation has been cited as a successful example of a restaurant chain run by a Japanese trading house, which typically invests in companies across industries. Mitsubishi established KFC Holdings Japan in 1970 as an equally owned company with KFC Corp. of the United States. The trading house has not only supplied chicken and other ingredients but also dispatched management personnel to the franchise.
