South Manchuria Railway
In 1937, under the direction of the Kwangtung Army, Japanese industrialist Yoshisuke Aikawa organized a holding company called the Manchurian Industrial Development Company ("Mangyō"), a Manchukuo "zaibatsu" with major shareholdings in the South Manchuria Railway, co-owned by Nissan and Manchukuo. The new "zaibatsu" invested heavily in Shōwa Steel, and took a controlling interest.
