This report looks at the pros and cons of the alliance with Japan, in which the United States maintains exclusive use of 89 military bases in Japan and, in exchange, guarantees Japan's security. The alliance has endured over 50 years, through periods of intense partnership and stretches of political drift; this report reevaluates the relationship based on international developments.

This report discusses issues regarding U.S.-Japan economic relations, since the economic condition of each nation can affect the world economy and a U.S.-Japan bilateral economic relationship could influence economic conditions in other countries. U.S. and Japanese leaders have several options on how to manage their relationship, including stronger reliance on the World Trade Organization; special bilateral negotiating frameworks and agreements; or a free trade agreement.

The huge earthquake and tsunami that struck Japan's Fukushima Daiichi nuclear power station on March 11, 2011, knocked out backup power systems that were needed to cool the reactors at the plant, causing three of them to undergo fuel melting, hydrogen explosions, and radioactive releases. Radioactive contamination from the Fukushima plant forced the evacuation of communities up to 25 miles away and affected up to 100,000 residents, although it did not cause any immediate deaths. Studies of the Fukushima disaster have identified design changes, response actions, and other safety improvements that could have reduced or eliminated the amount of radioactivity released from the plant. As a result, Fukushima has prompted a reexamination of nuclear plant safety requirements around the world, including in the United States.

The March 11, 2011, earthquake and tsunami in Japan caused widespread devastation that affected many of the country's agricultural and fishery areas. The nuclear crisis that followed at the Fukushima Daiichi Nuclear Plant, and the subsequent detection of radioactive contamination of food produced near the disabled facility, further raised fears about the safety of Japan's food production systems and its future food exports. Most reports acknowledge that Japan's current production and supply shortages, along with rising food safety concerns and possible longer-term radiation threats to its food production, could limit Japan's food exports while possibly increasing its need for food imports in the future. It is still not clear what effect, if any, Japan's current food supply and demand situation will have on world farm commodity markets and food prices.
