Japan serves as an excellent case of the anomaly of the economic giant-political pygmy whose ability to influence international events is severely limited despite a manifest desire to play a larger role. Japan's attempts to achieve political standing commensurate with its economic clout internationally have enjoyed only minimal success.
Historical factors, especially its defeat in World War II and the Occupation of Japan by the United States, continue to influence Japan's postwar foreign policy. So too does the so-called “peace clause” of the U.S.-imposed Constitution and the pacifist public consensus that has grown around it.
Since the war Japan's defense alliance with the United States has had an enormous impact on foreign policy, both inhibiting and aiding Japan's relations with other states. Japanese dependence on American defense guarantees sometimes conflicts with Japan's attempts to strike a more independent foreign policy.
