Japan's postwar business system dates back to the dissolution of the zaibatsu during the Allied occupation. Central holding companies were dissolved and families and other owners were compensated with non-negotiable government bonds. Individual operating firms were then freed to act independently. At the same time, the government instituted antimonopoly legislation and formed the Fair Trade Commission. Together with agricultural land reform and the start of the labor movement, these measures helped introduce a degree of competition into markets that had not previously existed.
