Japan has lifted a long-standing ban on exporting lethal weapons, marking a significant turning point in its postwar defense policy and signaling a broader shift away from decades of pacifism.

The change allows Japanese companies to sell arms to 17 countries amid heightened security concerns in the region.

The decision was approved by the cabinet of Prime Minister Sanae Takaichi and allows Japan to sell a wide range of military equipment overseas, including fighter jets, missiles, and warships. The move reflects growing concerns in Tokyo about an increasingly complex and volatile regional security environment.

“In an increasingly severe security environment, no single country can now protect its own peace and security alone,” Takaichi said in a statement announcing the change.

She also stressed that Japan’s core identity would remain intact, adding there was “absolutely no change in our commitment to upholding the path and fundamental principles we have followed as a peace-loving nation for over 80 years since the war”.

Under the revised framework, Japan will be able to export all categories of defense equipment. However, sales will be limited to countries that agree to use the equipment in line with the United Nations Charter.

At least 17 countries with existing defense agreements with Japan are expected to be eligible, including key partners such as the United States and the United Kingdom. The list could expand if additional bilateral agreements are signed.

Previously, Japan’s arms export rules, first introduced in 1967 and strengthened in 1976, restricted overseas sales to non-lethal equipment such as surveillance systems and mine-clearing tools.

The updated policy removes those limitations, although a general ban on exports to countries actively involved in conflict will remain in place. Authorities say exceptions could still be made in “special circumstances” if Japan’s national security interests are at stake.

Chief Cabinet Secretary Minoru Kihara said the changes are “intended to safeguard Japan’s security and further contribute to the peace and stability of the region”.

Growing Defense Ties and Regional Demand

The policy shift comes as Japan expands defense cooperation with partners across the Indo-Pacific. Countries such as Australia, New Zealand, the Philippines, and Indonesia have shown interest in purchasing Japanese-made military equipment.

Tokyo recently signed a $7 billion agreement with Australia under which Mitsubishi Heavy Industries will build the first three of 11 warships for the Australian Navy.

At the same time, Japan’s Self-Defense Forces are taking on a more active role in regional security. They have joined joint military exercises with the United States and the Philippines as combat participants for the first time, rather than as observers.

These developments come amid rising tensions in the region, particularly around Taiwan and disputed waters in the South China Sea.

China and South Korea React

China has voiced strong opposition to Japan’s policy change, warning of potential destabilization. “The international community, including China, will remain highly vigilant on this, and firmly resist Japan’s reckless new-style militarization,” Chinese Foreign Ministry spokesman Guo Jiakun said.

Beijing has also criticized joint military exercises involving Japan, the United States, and the Philippines, arguing that they deepen divisions and increase tensions near sensitive areas, including Taiwan.

China considers Taiwan a breakaway province and has not ruled out the use of force to bring it under its control.

South Korea expressed a more cautious response, stating that Japan’s defense policy “should ideally be carried out in a manner that upholds the spirit of the Peace Constitution while contributing to peace and stability in the region”.

Historical tensions continue to shape reactions in Seoul, given Japan’s colonial rule over Korea from 1910 until the end of World War II.

Historical Context

Japan’s pacifist stance is rooted in its 1947 constitution, adopted after its defeat in World War II, including the atomic bombings of Hiroshima and Nagasaki. The constitution renounces war and limits the country’s military capabilities.

For decades, this framework shaped Japan’s identity as a peace-focused nation. However, gradual changes over the past decade have expanded its defense role.

In 2014, then-Prime Minister Shinzo Abe eased restrictions to allow joint development of military equipment with allies. In 2023, former Prime Minister Fumio Kishida took further steps by permitting exports of finished lethal weapons under certain conditions.

Takaichi’s latest move builds on these reforms and is widely seen as the most comprehensive shift yet. Supporters argue that Japan must adapt to new geopolitical realities, particularly given its proximity to major powers such as China, Russia, and North Korea.

Critics, however, warn that the country risks moving too far away from its pacifist principles and could become entangled in future conflicts.

Japan’s decision to lift its ban on lethal weapons exports represents a major turning point in its defense and foreign policy.

While the government insists that safeguards remain in place and that its commitment to peace is unchanged, the move reflects a clear effort to reposition Japan as a more active security actor.

As regional tensions continue to rise, the long-term impact of this shift will depend on how Japan balances its evolving military posture with its historical commitment to pacifism.
