Launched in 2010, the Japan Matters for America/America Matters for Japan project is a comprehensive and multi-activity effort to demonstrate and track Japan's importance to the United States, and the United States’ importance to Japan.

This project maps the trade, investment, employment, business, diplomacy, security, education, tourism, and people-to-people connections between the United States and Japan at the national, state, and local levels. Part of the Asia Matters for America initiative, this publication, the one-page summaries for states and congressional districts, and the website are resources for understanding the robust and dynamic US-Japan relationship.

East-West Center

The East-West Center promotes better relations and understanding among the people and nations of the United States, Asia, and the Pacific through cooperative study, research, and dialogue. Established by the US Congress in 1960, the Center serves as a resource for information and analysis on critical issues of common concern, bringing people together to exchange views, build expertise, and develop policy options. The East-West Center in Washington provides US and Indo-Pacific government stakeholders and program partners with innovative training, analytical, dialogue, exchange, and public diplomacy initiatives to meet policy priorities.
