Immediately following the end of the Second World War, the company returned to manufacturing vehicles. Fuso bus production resumed, while a small three-wheeled cargo vehicle called the Mizushima and a scooter called the Silver Pigeon were also developed. However, the zaibatsu (Japan's family-controlled industrial conglomerates) were ordered to be dismantled by the Allied powers in 1950, and Mitsubishi Heavy Industries was split into three regional companies, each with an involvement in motor vehicle development: West Japan Heavy-Industries, Central Japan Heavy-Industries, and East Japan Heavy-Industries.
