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. After a decade of restructuring it now concentrates on digital systems and services, green energy and mobility, selling grid equipment through Hitachi Energy, trains and signalling through Hitachi Rail, and storage and data platforms through Hitachi Vantara. 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.
