Japan Lifts Arms Export Restrictions, Allowing Weapons Sales to Allies

Japan has eased its arms export rules, allowing sales of lethal weapons to allies like the United States and United Kingdom. Prime Minister Sanae Takaichi says the move is needed for security, but China has criticised it as militarisation.

Japan has taken a major step in reshaping its long-standing defence policy by relaxing decades-old restrictions on arms exports, a move that signals a continued shift away from its traditional post-war pacifist stance.
Under the new decision announced by the government, Japan will lift the strict limits that previously restricted arms exports to only five non-lethal categories: rescue equipment, transport systems, warning devices, surveillance tools, and minesweeping technology. With these restrictions eased, Japan is now permitted to export lethal weapons to up to 17 countries with which it has defence agreements, including major allies such as the United States and the United Kingdom.
However, officials clarified that the long-standing restriction on selling weapons to countries involved in active conflicts will remain in place. Despite this, exceptions may be considered under what authorities describe as “special circumstances,” giving the government some flexibility in future decisions.
Prime Minister Sanae Takaichi described the policy shift as a necessary response to the increasingly complex global security environment. She argued that no single nation can guarantee its own peace and security alone in today’s geopolitical climate. At the same time, she emphasized that Japan remains committed to its identity as a peace-loving nation, maintaining that its core principles have not changed since the end of World War II more than 80 years ago.
Takaichi also stressed that Japan will adopt a more cautious and strategic approach when evaluating arms transfers, ensuring that each case is carefully assessed before approval. Her comments reflect an attempt to balance growing security concerns with domestic sensitivities around Japan’s pacifist traditions.
Chief Cabinet Secretary Minoru Kihara reinforced this position, stating that the updated export rules are designed to strengthen Japan’s national security while also contributing to peace and stability in the broader region. He framed the decision as part of a broader effort to modernize Japan’s defence capabilities in response to shifting global threats.
The announcement has drawn strong reactions internationally, particularly from China, which expressed serious concern over what it described as Japan’s increasing militarisation. Chinese officials warned that they would remain highly vigilant and firmly opposed to developments they see as destabilising for the region.
The policy shift coincided with Japan’s participation in large-scale military exercises involving the United States and the Philippines. Notably, Japan took part in these drills as an active combatant for the first time rather than as an observer. The exercises were held in strategic maritime areas close to contested waters, including zones near Taiwan, which remains a major point of geopolitical tension. China considers Taiwan part of its territory and has not ruled out the use of force to achieve reunification, making such exercises highly sensitive.
Regional responses have also reflected historical tensions. South Korea called on Japan to ensure that any changes to its defence posture remain consistent with its post-war pacifist constitution and contribute positively to regional peace and stability. Relations between the two countries remain influenced by unresolved historical grievances dating back to Japan’s colonial rule of Korea from 1910 to 1945.
Japan’s current defence transformation has been gradual but steady over the years. In 2014, then Prime Minister Shinzo Abe relaxed restrictions to allow joint weapons development with allies, opening the door for greater defence collaboration and technological exchange. In 2023, further changes allowed Japan to export finished lethal weapons abroad for the first time since World War II, marking a significant departure from its previous policies. The latest reforms build on these earlier changes and expand Japan’s role in the global defence industry.
Domestically, the debate remains deeply divided. Supporters of the policy argue that Japan must adapt to a rapidly changing security environment marked by growing tensions involving China, North Korea, and Russia. They believe stronger defence capabilities and international partnerships are essential for national security.
Critics, however, warn that the shift could erode Japan’s long-standing pacifist identity enshrined in its post-war constitution. They fear that expanding arms exports and military cooperation could gradually draw Japan into global conflicts and mark a fundamental change in its post-war political philosophy.
