Mitsubishi Heavy Industries, Ltd (三菱重工業株式会社 Mitsubishi Jūkōgyō Kabushiki-kaisha?), or MHI, is a Japanese company. It is one of the core companies of Mitsubishi Group.


In 1870 Yataro Iwasaki, the founder of Mitsubishi took a lease of Government-owned Nagasaki Shipyard. He named it Nagasaki Shipyard & Machinery Works, and started the shipbuilding business on a full scale. This shipbuilding business evolved into Mitsubishi Shipbuilding Co., Ltd., which became Mitsubishi Heavy Industries, Ltd. in 1934. It was the largest private firm in Japan, manufacturing ships, heavy machinery, airplanes, and railroad cars.

Following the end of World War II, and the dissolution of the zaibatsu MHI was divided into three entities: West Japan Heavy-Industries, Ltd., Central Japan Heavy-Industries, Ltd. and East Japan Heavy-Industries, Ltd. It was re-consolidated in 1964 and reborn as Mitsubishi Heavy Industries, Ltd.

In 1970, MHI's automobile department became independent and Mitsubishi Motors began manufacturing and marketing automobiles.

As the leading company of the Japan's aerospace industry, Mitsubishi Heavy Industries (MHI) has been engaged in the development and production of a wide variety of aerospace products and thus contributed to the advancement of Japan, a technology-oriented nation, through its cutting-edge technologies.[citation needed]

In the defense sector, MHI has consistently produced jet fighters for Japan Air Self-Defense Force and anti-submarine helicopters for Japan Maritime Self-Defense Force, as well as various other products, such as aero-engines, missiles and torpedoes. By license production and assembling, it produced 139 Mitsubishi F-15 from 1981 and produced Sikorsky S-70 family Mitsubishi H-60 helicopter 200 more from 1989. The company also plays an important role in the Ballistic Missile Defense System program. In addition, MHI is preparing itself to respond to the needs of the joint operation capabilities.

In the civil aircraft sector, MHI takes charge of the development and manufacture of major airframe components, including fuselage panels for Boeing 777 and composite-material wing boxes for the 787. In the space systems sector, MHI is the producer of the H-IIA and H-IIB launch vehicles, Japan's main rockets, and provides launch services to JAXA for them. The company is also involved in the International Space Station program.

On April 1, 2008, MHI established subsidiary Mitsubishi Aircraft Corporation to develop and produce the MRJ or Mitsubishi Regional Jet, a 70 to 90 passenger regional airliner. MHI is the plurality shareholder of the new company, with Toyota Motor Corporation owning 10%.[3]

The nuclear business of MHI operates facilities Kobe, Yokohama, Kanagawa,Takasago, Hyogo. It also operates a nuclear fuel manufacturing plant in Tōkai, Ibaraki which processes 440 Metric tons of Uranium per year.

MHI has also developed the Mitsubishi APWR, which, as of July 2007, has been selected for use in two sites in Japan and the United States. MHI has also signed a memorandum of understanding with Areva for the establishment of a joint venture for their next reactor design.[4]

MHI has also been selected as the core company to develop a new generation of Fast Breeder Reactors (FBR) by the Japanese government.[5] After that announcement was made, MHI established a new company, Mitsubishi FBR Systems, Inc. (MFBR) specifically for the development and realization for FBR technology, starting what is likely to be the most aggressive corporate venture into FBR and Generation IV reactor technology.[6]

Mitsubishi Heavy Industries - Nagasaki Shipyard & Machinery Works (三菱重工長崎造船所 Mitsubishi Juko Nagasaki Zosenjo?) is the primary shipbuilding division Mitsubishi Heavy Industries. It produces primarily specialized commercial vessels, including LNG carriers, oil tankers, and passenger cruise ships. In addition, it is also a producer of a wide variety of machinery for power plants, energy production and aerospace use.


In 1857, at the request of the Tokugawa Shogunate, a group of Dutch engineers began work on the Nagasaki Yotetsusho, a modern, western-style foundry and shipyard near the Dutch settlement of Dejima, at Nagasaki.[7] Renamed Nagasaki Seitetsusho in 1860, it was completed in 1861. Following the Meiji restoration of 1868, the shipyard was placed under control of the new Meiji government, and the first dry dock was completed in 1879.

In 1884 Yataro Iwasaki, the founder of Mitsubishi, leased the Nagasaki Seitetsusho from the government and re-named it the Nagasaki Shipyard & Machinery Works, and started the shipbuilding business on a full scale. He purchased the shipyards outright in 1887. The works was renamed Mitsubishi Shipyard of Mitsubishi Goshi Kaisha in 1893 and additional dry docks were completed by 1896 and 1905.[7] In 1891, Mitsubishi Heavy Industries - Yokohama Machinery Works started as Yokohama Dock Company, Ltd, it was established Ship repairs by a purpose, and service by 1897.[8]

The Nagasaki company was renamed Mitsubishi Shipbuilding & Engineering Company, Ltd. in 1917 and again renamed as Mitsubishi Heavy Industries in 1934. It became the largest private firm in Japan, manufacturing ships, heavy machinery, airplanes, and railroad cars. The Mitsubishi Heavy Industries merged the Yokohama Dock Company in 1935.[8] From its inception, the Mitsubishi Nagasaki shipyards were heavily involved in contracts for the Imperial Japanese Navy. The battleship Musashi was completed at Nagasaki in 1942.

The Kobe Shipyard of Mitsubishi Goshi Kaisha was established in 1905. The Kobe Shipyard merged Mitsubishi Heavy Industries in 1934, and the Kobe Shipyard constructed the ocean liner Argentina Maru (later the aircraft carrier Kaiyo), the submarine I-19 and the I-25.[9]

Following the dissolution of the zaibatsu after the surrender of Japan at the end of World War II, Mitsubishi divided 3 companies. The Mitsubishi Nagasaki came under the allocated of West Japan Heavy Industries, Ltd., and the Nagasaki Shipyard was renamed Mitsubishi Shipbuilding & Engineering Co., Ltd. in 1952.[7] The Mitsubishi Kobe Shipyard allocated to the Central Japan Heavy Industries,Ltd. in 1950.[9]

However, in 1964, the three independent companies of Mitsubishi Heavy Industries, decentralized in 1950, were merged again into one company under the name of Mitsubishi Heavy Industries, Ltd., and the Nagasaki works was renamed the Nagasaki Shipyard & Engine Works. The Kobe works becomes Mitsubishi Heavy Industries - Kobe Shipyard & Machinery Works in 1964. A container ship, a car carrier, a submarine were constructed in the Kobe.[10]

The Mitsubishi Heavy Industries - Shimonoseki Shipyard & Machinery Works was established in 1914. There produces the machines which are necessary for promotion of efficiency and maintenance and constructs the merchant ship.[11]
