NextFin News - Philippine President Ferdinand Marcos Jr. is concluding a high-profile four-day state visit to Tokyo, where Japanese Prime Minister Sanae Takaichi is offering lethal arms sales to Manila. This marks the first major test of Japan's historic decision in April 2026 to scrap its decades-old ban on lethal weapons exports, signaling a dramatic shift in regional security dynamics.
According to Business Standard, the two nations are negotiating the sale of multiple Abukuma-class destroyers and Japanese navy TC-90 training aircraft. Philippine Defence Minister Gilberto Teodoro Jr. has also expressed strong interest in acquiring Type-88 surface-to-ship missiles. These negotiations represent a concrete manifestation of Tokyo’s new defense posture, which seeks to transform Japan from a passive security provider into an active exporter of military hardware.
The geopolitical drivers behind this alignment are clear. Both Tokyo and Manila face escalating maritime disputes in the East and South China Seas. By equipping the Philippines with advanced naval and missile capabilities, Japan hopes to strengthen a critical maritime partner. This strategy aligns with the broader security architecture encouraged by the United States under U.S. President Trump, who has advocated for regional allies to take greater responsibility for their own defense.
Beyond hardware, the bilateral relationship is deepening on an institutional level. Marcos and Takaichi are expected to initiate formal talks to establish a military intelligence-sharing agreement. This pact would build upon the five coastal surveillance radars Japan previously provided to the Philippines under its official security assistance program. It would also complement the Reciprocal Access Agreement signed in 2024, which already permits the deployment of up to 1,400 Japanese military personnel for joint exercises on Philippine soil.
However, this rapid military convergence is not without significant friction. In Japan, the decision by the Takaichi administration to dismantle postwar pacifist export controls in April remains highly controversial. Critics within Japan’s parliament argue that exporting lethal weapons to active geopolitical flashpoints risks entangling the nation in foreign conflicts, potentially violating the pacifist principles enshrined in Article 9 of the constitution. For Japan's domestic defense industry, which has historically operated under strict domestic procurement limits, the transition to commercial arms exporting presents steep operational and reputational hurdles.
On the Philippine side, long-term political reliability remains a major concern for Japanese strategists. Marcos’s term is set to end in 2028, and Philippine foreign policy has historically been prone to dramatic shifts. Tokyo’s eagerness to institutionalize these defense pacts now—including a recent agreement allowing the tax-free provision of ammunition, fuel, and food during joint training—is a deliberate attempt to lock in the alliance. Japanese officials are acutely aware of how quickly bilateral ties cooled under former Philippine President Rodrigo Duterte, who pursued a much more accommodating stance toward Beijing.
Financial constraints also loom over Manila’s ambitious defense modernization. While the Philippine government is eager to acquire high-end Japanese military assets, the country's defense budget remains constrained. Purchasing multiple destroyers and advanced missile systems will require creative financing or substantial Japanese subsidies, raising questions about the fiscal sustainability of these acquisitions without long-term financial aid from Tokyo.
The state visit also touched on broader economic vulnerabilities. Marcos and Takaichi discussed energy cooperation, specifically focusing on a Japan-led multinational funding framework launched in April. This initiative is designed to help Southeast Asian nations stabilize their strategic oil reserves, a pressing concern as the ongoing conflict involving Iran continues to disrupt shipping through the Strait of Hormuz.
The integration of the two militaries is already moving past the planning stages. Under the terms of their bilateral agreements, Japanese forces are now regular participants in joint exercises, and the tax-free logistics pact signed earlier this year ensures that the physical infrastructure for joint operations is already being laid down, regardless of who occupies the presidential palace in Manila after 2028.
