Abstract: Abstract of the thesis entitled Internal Discrepancies over the Economic Deconcentration Policy during the period of Allied Occupation of Japan, 1945-1952 Submitted by Chan Wing Yan for the degree of Master of Philosophy at the University of Hong Kong in February 2007 Immediately after the Japanese unconditional surrender in the Second World War, Japan was jointly occupied by the Allied Powers led by the United States. Unprecedented changes were found in every aspect of the Japanese society. In the past few decades, consistent attention has been attracted to the experience and significance of the occupation reform program. Most research has focused on the endeavors dedicated to the democratization and its relevance to the course reversal brought by the outbreak of the Cold War. There is not too much known about how the directives were laid out at policy- making level and enforced by the Supreme Commander for the Allied Powers (SCAP) administrative organs. Since personal beliefs and personality of each staff varied, conflicts and controversies were indispensable in the course of policy design and implementation. Hence instead of justifying the policy oscillation was directly associated with the Cold War at the policy design level, it would be intriguing to know if there was any other factor that might have influenced the policy implementation at the execution level. This paper will explore how SCAP personnel formulated the zaibatsu dissolution policy in theory and brought it in force by different internal divisions throughout the occupation years. It will also evaluate the degree of autonomy and interdependence among the staff divisions which were subject to impose the directives from top down and attempted to make a tradeoff between the predetermined official line and reoriented policy in response to the pressure posed by the American Government, Japanese Government as well as the opposition groups since the reverse course. It aims at looking at the internal policy inconsistencies associated with the ever-changing international circumstances together with the reorientation of the economic democratization program in response to the firestorm of criticisms launched by those stakeholders of the zaibatsu liquidation program. Emphasis will be made on examining the policy controversy and personal hostility among the staff divisions and Washington appointed advisory board, and on handling the evolution of attitude of the occupation authority toward the economic deconcentration practice. Highlights will be on the Deconcentration Law and the prohibition of the zaibatsu trademark and trade name dispute in the midst of the occupation policy reorientation instructed by Washington and how the Economic and Scientific Section of SCAP resolved the personnel conflicts and then shaped the coherent policy practice among the Anti-trust and Cartel Division, Deconcentration Review Board and Finance Division.
