The Paradox of Antimilitarism: Civil-Military Relations in Post World War II Japan Takako Hikotani Submitted in partial fulfillment of the Requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2014 Copyright 2014 Takako Hikotani All Rights Reserved ABSTRACT The Paradox of Antimilitarism: Civil-Military Relations in Post World War II Japan Takako Hikotani The changing security environment in Asia has led to a renewed interest in the Japanese Self Defense Forces (SDF). However, the SDF itself remains a black box: assessed either in terms of its problematic legal standing or physical military capacity, but with limited understanding of the people within; who they are, what they do, and how they think. This dissertation opens up the black box and brings the SDF officers into the analysis of civil-military relations in post-war Japan. I present a theoretical framework inspired by principal-agent theory, in which I hypothesize that the type of control (ex-ante or ex-post) and preference divergence between the civilians and the military produces four different outcomes in civil-military relations: containment, auto pilot, conflictual, and cooperative (possibly excessive). I examine how civil-military relations in Japan evolved over time and across three realms of defense policy making, budget, personnel, and use of force; utilizing the findings from an opinion survey conducted among SDF officers and civilian elite addressing the “civil-military gap,” oral history records of former SDF leaders and civilian defense officials, and interviews with active duty SDF officers and civilian officials. My research shows that civil-military relations in Japan was generally calm, not because the ex-ante constraints were strong and suppressed the opposing views of the SDF, but because the policy preferences of SDF officers and civilian bureaucracy converged in support of the alliance relationship with the United States. Such preference convergence made it possible for the politicians to continue “auto-pilot control” of the SDF, which was convenient for politicians who preferred to avoid dealing with military matters in face of the anti-militaristic public. However, this led to two paradoxical outcomes: (1) the SDF came to enjoy their relative autonomy within the ex-ante constraints, and (2) the ex-ante constraints turned out to be self-binding for politicians, possibly hampering their ability to control the SDF ex-post. Institutional changes through the electoral and administrative reforms in the 1990s along with the perceived changes in the security environment surrounding Japan enhanced both the incentive and capacity of politicians to release the ex-ante constraints and to control the SDF in their own hands. Re-interpretation of the constitution to allow for collective self defense is a step in the same direction. Looking towards the future, the shift from ex-ante to ex-post control may result in tension between the civilians and SDF officers, in cases where their preferences diverge.

Just over a decade ago, a widely read book on Japanese security policy stated that “short of domestic revolution, it is virtually impossible for an autonomous military establishment to reemerge. (Katzenstein,1998)” The SDF was described to be “fenced in” by constitutional and legal constraints, an intrusive civilian bureaucracy and most importantly, by the anti-militaristic public. Now, the SDF seems to have jumped out of the fence and captured people’s attention, with its images shown on many recent books on the “rise” of Japan as a “military power.” Still, the SDF itself remains a black box: assessed either in terms of its problematic legal standing or physical military capacity, but very little discussion over who they are, what they do, and how they think. This dissertation aims to rectify such omission by bringing the Self Defense Force officers into the analysis of civil-military relations of post war Japan. I challenge the commonly held assumption that the SDF officers are always aggressive yet insignificant actors in the defense policy making process, and that the Japanese case is a unique case that requires a deep cultural explanation, mostly incomparable to other countries. Instead, I will first present a theoretical framework inspired by principal-agent theory that explains why “containing” the SDF was a politically cost-effective way for politicians to control the SDF in the short run, but has paradoxically led to the creation of a relatively autonomous SDF within its limits, and weakened the ability of politicians to control the SDF in the long run. 1 I will then turn to the military (SDF) side of the civil-military relationship. I will conduct an opinion survey among the elite SDF officers to examine the extent of civil-military convergence or divergence (gap) at three levels: (1) who they are: socio-demographic profile, political beliefs, confidence in the military and attitudes towards domestic and foreign policy issues, (2) policies they prefer: preference divergence or convergence over national security policy, in realms of threat assessment, defense resources, force maintenance and force employment, and (3) what they believe the role of the military (SDF) should be in the defense policy making process. My aim is to examine whether the apparent calm in civil-military relations in post-war Japan was due to successful “containment” of the SDF officers despite their differences in preferred policy, or because the preferred policies of the civilian elite and
