IHI Corporation

IHI Corporation is a Japanese heavy industry maker. Its website describes four main business areas. They are resource, energy and environment, social infrastructure, industrial systems and general-purpose machinery, and aero engine, space and defense. Aviation is one part of this wider group.

In aviation, the company is working on sustainable aviation fuel. It is developing a way to make materials for this fuel from hydrogen and carbon dioxide using renewable energy. The company says this can help cut carbon dioxide from the aviation industry. It also has a project on electrification of aircraft and engine systems. The aim is to lower aircraft emissions through total energy management.

Other parts of the group work on bridges, industrial machinery and plants. A news story on the site covers a suspension bridge in Braila, Romania. Another covers a compressor chosen for a liquid hydrogen terminal in Kawasaki. The group says it started with shipbuilding technology and used it in industrial machinery, plant manufacturing and construction.

The site lists the group's regional websites for the Americas and Asia Pacific. It also lists overseas offices, main overseas subsidiaries and joint ventures. News on the site covers investor relations and sustainability, with a note on a planned earnings briefing on 4 November 2026.

The contact page separates product inquiries from investor relations and research and development. It also has a procurement route for suppliers and a human rights grievance desk. Visitors can find document downloads for products on the site.
