Members of the Japan Ground Self-Defense Force conduct a brief aboard the amphibious assault ship USS America (LHA 6) during a recent visit as LHA 6 conducts routine operations in the Philippine Sea, Japan, Feb. 3, 2025. The visit was part of a broader effort by the U.S. Marine Corps, U.S. Navy, JGSDF and Japan Maritime Self Defense Force to enhance their military cooperation and interoperability. The U.S.-Japan alliance plays a key role in the defense against potential aggressors. To support these efforts, the Amphibious Ready Group and Marine Expeditionary Unit and the ARDR regiments continue to invest in interactions aimed at areas of mission complementarity to reliably and more capably respond in tandem to a crisis. These exchanges will further strengthen the Marines’ and ARDR’s ability to work together more seamlessly and maintain a robust deterrence presence in the region. The ARG/MEU, which consists of more than 5,000 Marines and Sailors, is currently underway conducting routine operations in the U.S. 7th Fleet's area of operations. 7th Fleet is the U.S. Navy's largest forward-deployed numbered fleet and routinely interacts and operates with allies and partners to preserve a free and open Indo-Pacific region.
