Following the dissolution of the "zaibatsu" after the surrender of Japan at the end of World War II, Mitsubishi divided into three companies in January 1950: Mitsubishi Nagasaki became "West Japan Heavy Industries, Ltd", the Kobe Shipyard became "Central Japan Heavy-Industries, Ltd.", and the Yokohama branch became East Japan Heavy-Industries, Ltd. On 28 April 1952 the Occupation of Japan ended, which meant that the ban on using zaibatsu names was lifted. Accordingly, all three companies changed names again on 7 May 1952: West Japan Heavy Industries (the Nagasaki Shipyard) was renamed "Mitsubishi Shipbuilding & Engineering Co., Ltd.", Central Japan Heavy Industries, Ltd. was renamed Shin-Mitsubishi Jukogyo K.K. (also trading as "Mitsubishi Heavy Industries, Reorganized, Ltd."; "shin" meaning "New"), while East Japan Heavy-Industries became Mitsubishi Nippon Heavy Industries.
