Japan’s easing of arms export rules, the country’s largest policy change in this area since World War II, has sparked interest among Allies across Europe and the Indo-Pacific. Tokyo’s revised implementation guidelines for its three principles on defense equipment transfer opens weapons sales to 17 countries, according to the Japanese news website nippon.com. The move came just days after Japan welcomed more than 30 NATO envoys for a visit after Tokyo announced a $6.5 billion deal to supply warships to Australia.
Shortly after the April 2026 announcement, France, the Philippines and Poland expressed interest in making deals with Japan as part of their own weapons modernization efforts. The revision removes five categories that had limited most defense equipment exports to rescue, transport, warning, surveillance and mine-sweeping equipment. Ministers and officials will instead assess the merits of each proposed sale, according to Reuters. Japan will keep in place three export principles that commit it to strict screening, controls on transfers to third countries and a ban on sales to countries involved in conflict. However, in a presentation outlining the changes, the government said it could make exceptions for national security.
The move aims to strengthen Japan’s defense industrial base and is another step away from the pacifist restraints that have shaped its postwar security policy. Tokyo also has increased efforts to deepen ties with other nations in the Indo-Pacific to counter the Chinese Communist Party’s attempts to grow regional influence.
“No single country can now protect its own peace and security alone, and partner countries that support each other in terms of defense equipment are necessary,” Japanese Prime Minister Sanae Takaichi said in a social media post on X, according to Reuters.
Polish Prime Minister Donald Tusk said Warsaw and Tokyo have elevated their relationship to the “highest level” in a comprehensive strategic partnership, according to a Polish government news release. Collaboration will span multiple areas, including the economic, agricultural and space sectors, according to the news release.
Philippine Defense Secretary Gilberto Teodoro welcomed Japan’s rule change, saying in a statement that it would provide access to defense “articles of the highest quality” that would “strengthen domestic resilience” and “contribute to regional stability through deterrence,” according to Reuters. The Philippines, together with Japan’s southwestern island chain, forms part of what defense planners call the first island chain, a string of islands that hems in China’s access from its coastal waters to the Western Pacific.
United States officials also welcomed the move. The change will enhance the defense capabilities of U.S. and Japanese Allies and “pave the way for a more secure and stable Indo-Pacific,” George Glass, the U.S. ambassador to Japan, wrote on X.
The new rules will allow for more defense industrial cooperation with Japan and will be “really valuable to us, to Europe and the entire Alliance,” Anita Nergaard, Norway’s ambassador to NATO, told The New York Times newspaper. “We are exactly at the point where we need to turn those commitments and funding into capabilities.”
