IHI Corporation (株式会社IHI, Kabushiki-gaisha IHI), formerly known as Ishikawajima-Harima Heavy Industries Co., Ltd. (石川島播磨重工業株式会社, Ishikawajima Harima Jūkōgyō Kabushiki-gaisha), is a Japanese engineering corporation headquartered in Tokyo, Japan that produces and offers ships, space launch vehicles, aircraft engines, marine diesel engines, gas turbines, gas engines, railway systems, turbochargers for automobiles, plant engineering, industrial machinery, power station boilers and other facilities, suspension bridges and other structures.
IHI is listed on the Tokyo Stock Exchange Section 1.
IHI develops, manufactures, and maintains aero engines, either by joint projects of which partners include GE Aviation, Pratt & Whitney, and Rolls-Royce Holdings, or the company itself.
Shipbuilding was the founding activity of Ishikawajima in 1853 and is still part of IHI Corporation businesses, although diluted through several mergers with other Japanese shipbuilding companies.
In 1960, Ishikawajima Heavy Industries Co., Ltd. and Harima Shipbuilding & Engineering Co., Ltd. merged to establish Ishikawajima-Harima Heavy Industries Co., Ltd. (IHI). In 1995 Marine United was established jointly with Sumitomo Heavy Industries, Ltd. In 2013 IHI Marine United Inc. was merged with Universal Shipbuilding Corporation owned by the steel company JFE Holdings, Inc., to establish a new, larger company, Japan Marine United Corporation ('JMU') of which IHI remained a shareholder.
In March 2020 Japan Marine United (with 49% of shares) agreed to merge with Imabari Shipbuilding (with 51% of shares) into a joint venture named Nihon Shipyard ('NSY'), covering all ship types except Liquefied natural gas ('LNG') tankers. This agreement became effective in January 2021. In parallel with the creation of Nihon Shipyard, Imabari Shipbuilding bought 30% of JMU's shares, while IHI Corp. and JFE Holdings each kept 35% of JMU's capital. The merger between these two Japanese companies makes Nihon Shipyard one of the largest marine engineering and shipbuilding company in the world, of which IHI Corp. remains a shareholder.
