Hitachi was founded in 1910 by electrical engineer Namihei Odaira in Ibaraki Prefecture. The company's first product was Japan's first 4-kilowatt induction motor, initially developed for use in copper mining. The company began as an in-house venture of Fusanosuke Kuhara's mining company in Hitachi, Ibaraki. Odaira moved headquarters to Tokyo in 1918.
In October 2019, the talks between Honda and Hitachi to consolidate their four automotive parts businesses, Showa, Nissin and Keihin of the former and the latter's Hitachi Automotive Systems, have reportedly begun, resulting in the creation of a "mega supplier" named Hitachi Astemo incorporated in January 2021.
