Mitsui

Mitsui Group (三井グループ, Mitsui Gurūpu) is a Japanese corporate group and keiretsu that traces its roots to the zaibatsu groups that were dissolved after World War II. Unlike the zaibatsu of the pre-war period, there is no controlling company with regulatory power. Instead, the companies in the group hold shares in each other, but they are limited to exchanging information and coordinating plans through regular meetings.

The major companies of the group include Mitsui & Co. (general trading company), Sumitomo Mitsui Banking Corporation, Nippon Paper Industries, Pokka Sapporo Holdings, Toray Industries, Mitsui Chemicals, Isetan Mitsukoshi Holdings, Sumitomo Mitsui Trust Holdings, Mitsui Engineering & Shipbuilding, Mitsui O.S.K. Lines and Mitsui Fudosan.
