The Japan-U.S. Alliance and East Asian Security

Abstract

Recently, the national security environment surrounding Japan has become more severe than before. North Korea and China are the cause of such diffi cult conditions. North Korea is developing nuclear weapons and long-range missiles, and Peoples Republic of China intends to expand its infl uence in international society. Therefore, Japan is trying to respond these threats, and the United States of America, allied sate of Japan, has given up its ‘engagement’ policy towards China. Under the Trump administration, the U.S. has adopted a strong posture towards China. The U.S. presence in East Asia has contributed to keeping this region relatively stable. So, Japan has to maintain cooperation with the U.S. to sustain freedom, prosperity and peace in this region.
