This CRS report discusses recent developments in Japan- U.S. relations, the North Korean Nuclear Test and Missile Launches, the Global Financial Crisis and Economic Downturn, and Political Paralysis in Tokyo, in addition to the following topics: major diplomatic and security issues, regional and historical issues, military issues, economic issues, and Japanese politics. "The post-World War II U.S.-Japan alliance has long been an anchor of the U.S. security role in East Asia. The alliance, with its access to bases in Japan, where about 53,000 U.S. troops are stationed, facilitates the forward deployment of U.S. military forces in the Asia-Pacific, thereby undergirding U.S. national security strategy. For Japan, the alliance and the U.S. nuclear umbrella provide maneuvering room in dealing with its neighbors, particularly China and North Korea."
