Hitachi is a Japanese conglomerate founded in 1910 by Namihei Odaira as an electrical repair shop inside a copper mine, which grew into one of the country's largest industrial groups.

Its Lumada portfolio ties operational technology to software, and the 2021 acquisition of GlobalLogic gave the group a large digital engineering arm serving customers outside Japan.
