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.
In September 2020, Hitachi pulled the plug on plans to create nuclear power plants in Gloucestershire and Wales due to issues with funding due to the impact of COVID-19.
