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. It remains part of IHI's business activities, although it has been diluted through several mergers with other Japanese shipbuilding companies.
In 1960, Ishikawajima Heavy Industries merged with Harima Shipbuilding & Engineering Company to establish the Ishikawajima-Harima Heavy Industries (IHI). In 1995, Marine United was established jointly with Sumitomo Heavy Industries. In 2013, IHI Marine United was merged with Universal Shipbuilding Corporation owned by the steel company JFE Holdings in order to newly establish a larger firm, 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 and JFE Holdings each kept 35% of JMU's capital. The merger between these two Japanese companies resulted in Nihon Shipyard becoming one of the largest marine-engineering and shipbuilding companies in the world, of which IHI remains a shareholder.
