The Japan lobby are a group of advocacy organizations influencing American policy towards Japan. The lobby has persisted since the Allied Occupation of Japan following the Pacific War. The Post-occupation lobby has been organized and headed since the occupation by Ministry of International Trade and Industry and the Foreign Ministry.[1] The purpose and political influence of the lobby has shifted over time from journalists and American interest groups advocating for land reform and corporate restructuring in the occupation period[2] to multinational groups employing over 1,000 lobbyists.[3]
