Part II - “Zaibatsu” and “Keiretsu” - Understanding Japanese Enterprise Groups

By Andrew H. Thorson

This Article is Part II of a series that explains the origins of the Japanese corporate complexes that have characterized Japan’s modern economy. Part I explained the origins of pre-WWII zaibatsu. This part discusses the dissolution of the zaibatsu and origins of the current company groups known as the keiretsu.

Zaibatsu Dissolution: As explained in the previous article, by 1945 the zaibatsu had grown to control a significant portion of Japanese trade and industry. During the Allied occupation, the zaibatsu were liquidated in order to “democratize” Japan’s economy. In addition, for the purpose of controlling concentrations of economic power, special provisions were included in Japan’s Antimonopoly Act for the specific purpose of forbidding holding companies and limiting the acquisition by financial enterprises of stock of other companies. In hindsight these provisions might appear to have been ineffective barriers to the creation of excessive economic control and equally ineffective as measures to ensure competition in Japan’s economy. These arguments were made when Japan enacted the Act for partial Amendment of the Antimonopoly Act in 1997 by which act Japan finally eliminated the 50-year old ban on holding companies.

The zaibatsu were dismantled by (i) destruction of pyramid control structures via liquidations, (ii) public dispositions of zaibatsu-owned shareholdings, (iii) reorganization of large existing monopolies, and (iv) strengthening of the legal prohibitions on monopolies and unfair competition. The Imperial Order of 1946 Concerning the Restriction, etc., of Securities Holdings by Companies also forbids certain interlocking relationships among former zaibatsu members via personnel, shareholding, loans, and contractual ties. In all, 1200 companies and 56 individual members of zaibatsu families had their assets frozen and transferred to what was known as the Holding Company Liquidation Commission.

Political Overtones of Dissolution: While the Allied presence influenced the dissolution of the zaibatsu, there are also suggestions that bureaucrats in Japan desired to liquidate the zaibatsu for political reasons of domestic politics, including perhaps for the purpose of strengthening the Ministry of Finance’s (MOF) control over Japan’s economy. From the late 1930’s, powerful Japanese stockholders were also under public attack for emphasizing private profit interests over what were perceived to be public interests and the interests of labor. On the domestic level, zaibatsu became targets of social resentment, and managers of leading zaibatsu were sometimes even subject to terrorist attacks. The theory that zaibatsu dissolution implicated a power coup between the MOF and the zaibatsu rather than a real desire to eliminate concentrations of economic power is arguably consistent with the circumstances which followed dissolution, namely, the emergence of new and powerful corporate groupings in Japan.

New Corporate Groups – Emergence of Keiretsu: Within years of dismantling the zaibatsu, changes on both the domestic and international fronts are thought to have led to a relaxation of regulations upon the concentration of economic power in Japan. On the latter front, following the establishment of communist China, U.S. foreign policy toward Japan could be seen shifting to one supporting a shoring up of Japan’s economic power. Secondly, industrial growth and increased production capacity in Japan supported the U.S. need for supplies during the Korean War. Domestically, legislation in 1949 and subsequently in 1953 relaxed restrictions under the Antimonopoly Act. By 1953, financial companies were permitted to own up to 10% of the outstanding shares of non-financial companies and the prohibition upon holding the stock of competing companies was eliminated.

Government policies in support of economic and industrial growth also tended to promote a new pooling of resources and grouping of enterprises during this period. When the Korean War ended and some large industrial companies faced over capacity problems, governmental policies supported greater cooperative efforts among enterprises. For example, in 1953 the Ministry of International Trade and Industry’s (MITI, now known as METI) Industrial Rationalization Counsel called for the grouping of trading and manufacturing companies to concentrate scarce capital in the domestic economy. Antimonopoly restrictions were also relaxed during this period. In this environment the currently existing corporate groups began to crystallize.

By the 1960’s six “quasi-zaibatsu” had emerged, including the following groups: Mitsui; Mitsubishi; Sumitomo; Fuyo; Sanwa; and Dai-Ichi Kangyo. Of these six, Mitsui, Mitsubishi and Sumitomo have been called the most direct successors of the pre-war zaibatsu. In contrast to actual zaibatsu, however, large financial institutions, under the influence of MOF, have been said to play a central role in corporate governance. The current groups are arguably so substantively different from original zaibatsu that it could be misleading to refer to them as “quasi”-zaibatsu.

As will be explained in Part III of this series, the current company groups that we often loosely lump together and refer to as keiretsu¸ include horizontal and vertical company relationships, and sometimes business ties that are held together not by capital but by mere transactional relationships among enterprises. The central role of main banks in corporate governance greatly distinguishes these groups from the zaibatsu.
