MHI’s monozukuri began with the lease of Nagasaki Shipyard & Machinery Works from the Ministry of Industry. Even as the Company built Japan’s first steel steamship and battleships, it applied the technologies and knowledge cultivated in those endeavors to begin production of automobiles and aircraft, expanding its range of business as a comprehensive manufacturer of transport equipment. As global tensions rose, the Company entered into an age where its technologies? more advanced than in most countries at that time?would be diverted to military use.
After the war, in accordance with national policy, MHI shifted its emphasis from military hardware to the development and manufacture of scooters, air conditioners, and many other types of consumer products. In 1950, in line with the GHQ’s policy of dissolving large industrial groups (zaibatsu), MHI was divided into three independent companies. As a result, the scale of products grew more diverse, and the three companies fell into competition. However, this technology race would provide the foundation for the leading company in heavy industry.
In 1964, the same year Tokyo hosted the Summer Olympics, the three principal heavy industry companies reunited, creating the current form of Mitsubishi Heavy Industries. Its products expanded to encompass the fields of land, sea, and air, and included oil-drilling rigs, power plants, tankers, and bridges. In addition, the successful lift-off of the H-I launch vehicle occurred around this time, and the Company’s participation in full-fledged space development began.
MHI has always sought high efficiency, and as the trend toward global environmental conservation gains momentum and the concept of ecology becomes commonplace, the Company’s gas turbine, eco-ship, and other technologies and product fields are expanding on a global scale. As a comprehensive infrastructure company, MHI works to develop the technologies and products that will support a sustainable society.
