Kyodo News, citing government sources, reported that Japan and the Philippines are informally discussing the possibility of exporting the Type-03 Chu-SAM medium-range air defense missile system to Manila. These discussions are taking place alongside a plan by Prime Minister Sanae Takaichi's government to lift restrictions on defense exports; a formal decision is expected in the first half of 2026. According to the sources, the Philippines has expressed interest in the Type-03 Chu-SAM.
Policy Overview
The review of easing defense export restrictions is expected to be conducted by Japan's National Security Council, chaired by Prime Minister Takaichi, without amending existing laws. Currently, regulations only allow the export of five non-combat items: rescue, transport, warning, reconnaissance, and mine-clearing equipment.
The ruling coalition, comprising the Liberal Democratic Party and the Japan Innovation Party, included lifting export restrictions in its political agreement. Allowing the sale of air defense systems would represent a fundamental shift in Japan's post-war military policy. According to Kyodo News, the government's stance on arms sales under Prime Minister Takaichi has become more assertive, aiming to accelerate participation in international defense partnerships.
Japan eased its arms export ban in 2014, allowing the sale of military equipment under strict conditions. In 2023, it supplied domestically produced Patriot missiles to the United States, setting a precedent for exporting complete missile systems.
