Mitsuhishi Group

The Mitsuhishi Group (光菱系列), also known as the Mitsuhishi Keiretsu, is a group of autonomous Yamataian multinational companies in a variety of industries.

Founded by Hamaura Ayano in 1870, the Mitsuhishi Group historically descended from the Mitsuhishi zaibatsu, a unified company which existed from 1870 to 1935. Following the 1935 Escaric economic crisis, the zaibatsus were forcibly disbanded by the military government and many industries were nationalised. Following the war and the eventual liberalisation of the Yamataian economy in the 1950s, the former constituents of the company continue to share the Mitsuhishi brand and trademark.

Although the group companies participate in limited business cooperation, most famously through monthly "Wednesday Conference" executive meetings, they are formally independent and are not under common control. The four main companies in the group are Mikogi Bank (the largest bank in Yamatai), Mitsuhishi Corporation (a general trading company), Mitsuhishi Electric and Mitsuhishi Heavy Industries (both being diversified manufacturing companies).
