III Marine Expeditionary Force Marines and Sailors will participate in exercise Keen Sword 25, a joint-bilateral biennial exercise, alongside the Japan Self-Defense Force from October 23 through November 1, 2024, throughout Japan.
Keen Sword 25 is a field training exercise designed to enhance U.S.-Japan readiness and interoperability while strengthening the bilateral relationship and showcasing U.S. resolve to support the security interests of allies and partners in the region.
The exercise demonstrates and advances U.S.-Japan interoperability, validates force posture, and reinforces solidarity of the U.S.-Japan alliance by exercising the most modern equipment and procedures under realistic conditions. Approximately 900 Marines and Sailors from across III MEF will participate.
“III MEF is committed to conducting realistic exercises with our allies and partners, and we will continue to deploy and train alongside partner forces in exercises like Keen Sword,” said U.S. Marine Corps Lt. Gen. Roger B. Turner, the III MEF commanding general. “The U.S.-Japan Alliance has served as the cornerstone of peace, security, and prosperity in the Indo-Pacific and across the world for over seven decades and has never been stronger.
III MEF contributions to this iteration of Keen Sword will include a bilateral amphibious assault with the JSDF Amphibious Raid Deployment Brigade, humanitarian aid and disaster relief training, a forward arming and refueling point, live-fire training, and additional bilateral events and subject matter expert exchanges.
Live-fire exercises, like Keen Sword, are one of the most valuable ways for our forces to train in their craft and validate the ability to defend U.S. allies and partners as a vital part of our mission. Conducting training in different locations across the region allows the U.S. military to continue to learn and improve their proficiency to support a Free and Open Indo-Pacific.
All participating units, to include participants from the Australian Defence Force and Canadian Armed Forces, will train in a comprehensive scenario designed to exercise the critical capabilities required to support the defense of Japan and to respond to a crisis or contingency in the Indo-Pacific region.
The KS25 scenario has no connection to existing regional events, nor is it directed at any single nation. Originating in 1986, this training between the United States and Japan has been a routine, recurring event to bolster the U.S.-Japan Alliance.
The U.S.-Japan alliance remains a cornerstone of regional peace and security in the Indo-Pacific region. Keen Sword provides realistic, relevant training that increases the U.S. and Japan’s abilities to plan, communicate, and conduct complex multi-domain operations.
