The move aimed at strengthening Japan’s defence industrial base marks another step away from pacifist restraints that have shaped its postwar security policy.
Wars in Ukraine and the Middle East are also straining US weapons production, expanding opportunities for Japan. At the same time, US allies in Europe and Asia are looking to diversify suppliers as Washington’s long-held security commitments look less certain under President Donald Trump.
“No single country can now protect its own peace and security alone, and partner countries that support each other in terms of defence equipment are necessary,” Japanese Prime Minister Sanae Takaichi said in a post on X.
Japanese officials and diplomats have told Reuters that countries ranging from Poland to the Philippines are exploring procurement opportunities as they modernise their forces. One of the first deals could be the export of used warships to Manila, two of the sources said.
Philippine Defense Secretary Gilberto Teodoro welcomed Japan’s export rule change, saying in a statement that it will give his country access to defence “articles of the highest quality” that would “strengthen domestic resilience” and “contribute to regional stability through deterrence.”
The revision approved by Takaichi’s government removes five export categories that had limited most military exports to rescue, transport, warning, surveillance and minesweeping equipment. Ministers and officials will instead assess the merits of each proposed sale.
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. But in a presentation outlining the changes, the government said exceptions could be made when deemed necessary for national security.
Japan also building its own military
Tokyo hopes such defence exports will shore up its industrial base by boosting production volumes, lowering per-unit costs and adding manufacturing capacity it could draw on in a military crisis.
Contractors such as Mitsubishi Heavy Industries can build advanced systems including submarines, fighter aircraft and missiles, but for decades have depended on small orders from a single customer, Japan’s Self-Defense Forces.
Japan is pressing ahead with unprecedented efforts to bolster its military – buying missiles, stealth jets and drones it says are needed to deter any threat posed by neighbouring China to its territory, including around islands along the edge of the East China Sea near Taiwan.
Beijing has said its intentions in East Asia and elsewhere are peaceful.
Tokyo is also developing a next-generation fighter jet with Britain and Italy for deployment in the mid-2030s, part of a strategy to share development costs and gain access to new technology.
Japan has steadily increased defence spending in recent years to 2% of GDP, and Takaichi’s government is expected to announce further rises this year when it releases a new security strategy.
