Abstract: As the successor of Shinzo Abe, Japan's longestserving prime minister, Prime Minister Yoshihide Suga said in his congressional policy address that the JapanUS alliance is the cornerstone of Japan's diplomacy and security. It is also the foundation of freedom, peace and prosperity in the IndoPacific region and the international community. Japan will work with Presidentelect Joe Biden to further strengthen solidarity between Japan and the United States. JapanUS relations will continue to cooperate in bilateral, international, regional, and human rights political relations. There are important differences in the governing ideas and styles between Prime Minister Yoshihide Suga and President Biden, but this will not lead to major differences and conflicts in the relations and policies between Japan and the United States. It is easy to form a new complementarity of relations and policies between the two countries－ from the Abe administration to induce the Trump administration in the international pattern and policies in the past, to the Biden administration to lead allies such as Japan, using various international institutions and systems around the world to safeguard the values and national interests of the United States, while the Japanese government of Yoshihide Suga followed the United States closely to realize its own national interests.

Key words: Japan-U.S.relations, bilateral relations, Biden Administration, Suga Cabinet, Indo-Pacific Strategy
