This report discusses the effects of the possible entry of Japan to the Trans-Pacific Partnership (TPP) negotiations. The TPP issue presents both risks and opportunities for the United States and Japan. On the one hand, it could reinvigorate an economic relationship that has remained steady but stagnant, by forcing the two countries to address long-standing, difficult issues, and allowing them to raise their relationship to a higher level. On the other hand, failure to do so could indicate that the underlying problems are too fundamental to overcome and could set back the relationship.

This report briefly discusses the March 11, 2001 earthquake off the east coast of Honshu, Japan's largest island. The earthquake caused an automatic shutdown of eleven of Japan's fifty-five operating nuclear power plants, though the plants closest to the earthquake's epicenter, Fukushima and Onagawa, were damaged by the earthquake and resulting tsunami. This report also discusses efforts by the United States and other countries to provide assistance to Japan to deal with the nuclear crisis.
