ABSTRACT
The development of big business in the process of rapid economic growth of Japan in the late fifties and the early sixties was truly spectacular. In manufacturing industries, in particular, big business accomplished very rapid capital accumulation by adopting technological innovations based on imported technology and succeeded in strengthening its international competitive power. Japanese industry is broadly divided into two main groups: a key industrial sector controlled by a few large oligopolies with advanced technology and a secondary processing sector crowded by a mass of small and tiny enterprises with underdeveloped technology. The series of postwar reforms like the zaibatsu dissolution, the deconcentration of economic power, and the purge of business executives responsible for the war and the subsequent economic growth brought about the collapse of the owners' control of Big Businesses. Managers of big business therefore have the authority to determine how to employ managerial resources that have been accumulated in the business.
