再軍備する日本 Japan Rearmed: The Politics of Military Power
Japan’s strategy of possessing limited military power and relying on its alliance with the United States has served it well, and yet in today’s Asia, Tokyo’s approach to military power is being tested. Northeast Asia has become a far more contested region as Chinese military power increases and as North Korea seeks to become a nuclear state. Japan’s Self-Defense Force (SDF) now regularly runs up against the expanding armed forces of its neighbors. China’s growing military has led to serious clashes with Japan. Chinese maritime and air patrols operate with increasing frequency and regularity in proximity to Japan, and Beijing has challenged Japanese sovereignty over the Senkaku Islands (Diaoyu in China), sending its coast guard and naval vessels to the East China Sea to assert its claims. The failure of diplomacy to resolve these tensions has at times all but broken communication between Tokyo and Beijing, and rising contact between Japanese and Chinese militaries has intensified concern that a miscalculation or unintended incident could easily bring the two Asian nations into conflict. The lack of agreement between Japan and China on their maritime boundary also exacerbates this risk. Tokyo has consulted with Washington on how to de-escalate tensions during these moments of crisis with Beijing. Japanese officials worry about “gray zone” contingencies—clashes below the actual use of armed forces but which could easily escalate to a military conflict.
