Marubeni merged with Takashimaya-Iida, a trading company that owned the Takashimaya department store chain, in 1955, changing its name to Marubeni-Iida from 1955 to 1972. The merger was orchestrated by Fuji Bank in order to create a stronger trading company partner for the bank's corporate customers. Marubeni and Fuji Bank developed a network of corporate clients which was formalized as the Fuyo Group "keiretsu" in the 1960s, paralleling the development of the DKB Group and Sanwa Group. The Fuyo Group included Hitachi, Nissan, Canon, Showa Denko, Kubota and Nippon Steel.
