Japan eases postwar defense policy, opens door to lethal weapons exports

By The South Asia Times

TOKYO - Japan has taken a historic step by easing its long-standing postwar restrictions on defense exports, allowing the transfer of lethal weapons for the first time since World War II, in a move that signals a major shift in its security policy.

Prime Minister Sanae Takaichi announced that the government has amended the “Three Principles on Transfer of Defense Equipment and Technology,” expanding export rules beyond the previously limited five categories of nonlethal equipment such as rescue, transport and surveillance systems.

Under the revised framework, transfers of a broad range of defense equipment—including lethal systems—will now be “in principle possible,” although subject to strict case-by-case review and international export control standards. Recipient countries will be required to adhere to the UN Charter and ensure proper management of the equipment.

Takaichi said the policy shift reflects a “severe and complex security environment,” arguing that no country can ensure its security alone and that closer defense cooperation with partners is essential. She added that enabling such transfers would strengthen allied capabilities and help deter conflicts, while also enhancing interoperability through shared systems and parts.

Despite the change, the prime minister stressed that Japan remains committed to its identity as a “peace-loving nation” and would apply rigorous safeguards to all exports.

The move has drawn sharp criticism from opposition figures, including Kazuo Shii, who condemned the decision as an “unreasonable reversal” of Japan’s pacifist principles. He warned it could turn the country into a “merchant state of death” and called for the policy to be withdrawn.

The decision marks a significant turning point in Japan’s defense posture, reflecting its evolving role in regional and global security amid rising geopolitical tensions.
