The mission of the U.S. Department of Energy's Japan Office (DOE-TO) is to support implementation of DOE and NNSA nonproliferation and energy programs in Japan, as well as provide support for initiatives in Asia and the Pacific Rim countries. The strategic relationship has been critical for national security in the Asia-Pacific region in view of a number of tensions between neighboring states with nuclear weapons capability or aspirations for this capability.
The U.S. and Japan have a long-standing and successful bilateral relationship. DOE-TO is responsible for providing on-site support to the full range of DOE/NNSA and U.S. Government interests with a focus on nonproliferation, energy security, nuclear energy and fuel cycle research and development, energy efficiency and the advancement of science and technology involving DOE and a number of governmental, quasi-governmental and non-governmental organizations. DOE-TO also provides monitoring and support activities for several ongoing nuclear activities/projects in other Asian Countries. The Office maintains continuous contact with the Japanese Ministry of Foreign Affairs, Education, Culture, Sports, Science and Technology, Economy, Trace and Industry and other organizations related to nuclear energy, submarine dismantlement, vehicle manufacturers and others. DOE-TO pays a valuable role in furthering collaboration and coordinating USG policy positions with international agencies where the U.S. and Japan are key contributors, such as the IAEA, the IEA and the OECD/Nuclear Energy Agency (NEA). DOE-TO is the central point for all DOE/NNSA activities in the region and an essential part of the overall DOE/NNSA international mission.
