Mitsubishi Heavy Industries

Mitsubishi Heavy Industries is a major Japanese multinational engineering, electrical equipment, and electronics corporation headquartered in Tokyo. It is a core company of the Mitsubishi Group and one of the world's leading industrial manufacturers, with a history tracing back to the Meiji period. The company's diverse operations span the aerospace, energy, defense, and infrastructure sectors, playing a significant role in Japan's technological and industrial development.

History

The company's origins date to 1884 when Yataro Iwasaki, founder of the Mitsubishi zaibatsu, took over the Nagasaki Shipyard from the Japanese government, which later became Mitsubishi Shipbuilding Co., Ltd.. It expanded rapidly, constructing Japan's first modern steamship, the Hitachi Maru, and later diversified into aircraft manufacturing, producing the famed Mitsubishi A6M Zero fighter for the Imperial Japanese Navy during World War II. After the war, the company was broken up under the Allied occupation but re-merged in 1964 to form the present entity. Key historical milestones include its role in developing the Mitsubishi Regional Jet, the H-IIA rocket for the Japan Aerospace Exploration Agency, and pioneering technologies in thermal power and air conditioning.

Its portfolio is organized around integrated business domains. The Energy Systems segment designs and builds gas turbines, geothermal power plants, nuclear reactors, and wind turbines, including technology for advanced pressurized water reactors. The Plant & Infrastructure Systems unit handles chemical plants, desalination facilities, steelmaking equipment, and air conditioning systems, notably under the Mitsubishi Electric brand for elevators. The Logistics, Thermal & Drive Systems division manufactures forklift trucks, refrigeration units, and turbochargers. The Aircraft, Defense & Space segment produces commercial aircraft components for Airbus and The Boeing Company, missile systems like the Type 12 Surface-to-Ship Missile, and satellite components.
