Japan scraps most arms export restrictions, approves lethal weapons sales abroad

Japan's government approved removing most restrictions on overseas arms sales on April 21, 2026, clearing the way for exports of warships, tanks, and missiles. Prime Minister Sanae Takaichi's administration framed the policy shift as necessary to strengthen Japan's defense posture and deter regional threats. The move marks a significant departure from Japan's decades-long self-imposed arms export limits, rooted in its post-World War II pacifist constitution. The decision carries direct implications for U.S. Indo-Pacific strategy, as Japan is a core American security ally whose military capabilities directly affect regional force balance against China and North Korea.
