The Japanese keiretsu have been described in similar terms, yet compared to business groups in other countries the postwar keiretsu warrant the “group” label least. The prewar progenitor of the keiretsu, the zaibatsu, however, could fairly be described as groups, and, in their relatively sharp boundaries, hierarchical structure, family control, and close ties to the state were structurally similar to business groups elsewhere in the world. With the break-up by the U. S. Occupation of the largest member firms, the purging of their executives, and the outlawing of the holding company structure that held them together, the zaibatsu were transformed into quite different business entities, what we and other literature call “network forms” of organization (Podolny and Page, 1998; Miyajima, 1994).
