The Treaty of Mutual Cooperation and Security between Japan and the United States of America (the Japan-US Security Treaty) as well as the alliance relations based thereon have been cornerstones of post-war Japanese foreign policy. Japan and the US share the fundamental values and philosophies of freedom and democracy and are members of the liberal international order. They also possess both the will and the capacity to contribute to a more prosperous and secure world. JIIA conducts various research projects on US domestic politics and foreign policies as well as on Japan-US relations that provide useful inputs for policy makers, practitioners and researchers.
