Company information
"A company that is both old and new"! The predecessor of Mitsubishi Nagasaki Machinery was established as Mitsubishi Shipbuilding Co., Ltd. Nagasaki Steel Works during the Taisho era, and it traces back to Mitsubishi Steel Co., Ltd. Nagasaki Steel Works, which became independent in 1942. In 1975, it was established by inheriting the industrial machinery and steel structure manufacturing division of the company. The technology of Mitsubishi Nagasaki Machinery is based on the skills developed as a cast and forged steel manufacturer since the Mitsubishi Steel era. While supported by tradition and new technologies, it continues its unique research and development and technical refinement, skillfully blending engineering (design technology) and manufacturing (production technology) in a well-balanced manner, actively engaging in product development and business expansion.
