Japan and Its Military

Introduction

Since 1947, Japan's constitution has forbidden the formation of a traditional military force. The country has maintained only a Self Defense Force (SDF), the mission of which has been to protect the Japanese mainland. Even within these limitations, the SDF has performed a paramilitary, logistical role, supporting U.S. troops based in Japan in exchange for promises of protection. Some experts now see this dynamic shifting. Arguments for "remilitarization"—or military "normalization," as many proponents term it—have gained currency over the last two decades. Since 9/11, SDF forces have been deployed overseas for the first time (to Afghanistan and Iraq). Their roles have been almost exclusively support-based, but their deployment is seen as symbolic of a change in attitudes as well as a challenge to the constitution. Japan is already one of the world's largest spenders on national defense, and the SDF is a robust force, though expenditures are narrowly targeted and essentially protective—they include no long-range bombers or missiles, no aircraft carries or nuclear submarines. Japan has come under increasing pressure to redirect this focus and expand its military operations, both from the United States and also domestically, in response to feared threats from China and North Korea.
