Japan Lifts Postwar Ban on Lethal Weapons Exports

2026-04-21

The BareStory

The Japanese government, led by Prime Minister Sanae Takaichi, has formally ended its post-World War II ban on lethal weapons exports. The policy revision permits the international sale of military equipment, including missiles and warships, representing a significant shift in the country's long-held pacifist defense posture.

Prime Minister Takaichi stated that the current security environment necessitates mutual defense support among partner nations. Japanese officials noted the policy aims to counter regional security threats and stimulate Japan's domestic defense industry. According to the Cabinet's new guidelines, military sales will require National Security Council approval, mandate post-transfer monitoring, and remain prohibited to nations actively at war.

The regulatory change paves the way for new international defense contracts, highlighted by a recent agreement for Mitsubishi Heavy Industries to construct three warships for the Australian navy. Additionally, according to Japanese Defense Minister Shinjiro Koizumi, countries including New Zealand, the Philippines, and Indonesia have expressed interest in acquiring Japanese defense equipment.

The policy shift has faced domestic opposition from critics who argue it could exacerbate global tensions and violates Article 9 of Japan’s constitution, under which the country originally renounced war. Demonstrators recently gathered outside the National Diet Building in Tokyo to protest the export changes and voice support for the nation's constitutional pacifist provisions.
