Japan's decision to fully lift lethal weapon export restrictions signals a fundamental shift in its national security strategy. By leveraging defense exports to build deeper ties with Southeast Asian nations, Tokyo is attempting to mitigate its vulnerability to energy supply disruptions. This 'big picture' strategy transforms Japan from a passive consumer of security into an active architect of maritime stability in the Indo-Pacific.
