Why it matters
President Ferdinand Marcos Jr. arrived in Japan this week for a state visit that Manila has framed around security, energy and investment as tensions with China continue to shape Philippine diplomacy. The trip, running from May 26 to May 29, is Marcos’ first state visit to Japan and comes in the 70th year since the two countries normalized diplomatic relations. Japanese officials said Marcos and First Lady Louise Araneta-Marcos will meet Emperor Naruhito and Empress Masako and attend a state banquet. Marcos is also due to hold summit talks with Prime Minister Sanae Takaichi. ### Why is Marcos using this trip to press security ties with Japan? Marcos said on May 26 that the visit was “essential amid an increasingly challenging and evolving global environment” and part of a broader effort to forge closer political ties, stronger defense cooperation and more durable economic partnerships in the region. In his departure statement, he called Japan the Philippines’ “first and oldest Strategic Partner” and “a most reliable partner” in prosperity and uncertainty. (mofa.go.jp) Department of Foreign Affairs spokesperson Analyn Ratonel said earlier this week that Manila’s agenda in Tokyo included maritime security, defense cooperation, energy security and investments. Philippine media reports said Marcos has also sought clarity on Japan’s evolving defense posture and how that could affect regional security cooperation. (pco.gov.ph) ### What does China have to do with the visit? Marcos said before the trip that he intended to discuss “grey zone” tactics with Takaichi, referring to coercive actions below the threshold of open conflict. Philippine officials and analysts have tied that language to repeated confrontations in the West Philippine Sea, the term Manila uses for parts of the South China Sea within its exclusive economic zone. (gmanetwork.com) The South China Morning Post reported that analysts see Japan as a key counterweight for Manila as it deals with maritime pressure from China. Rappler reported that Japan has been one of the Philippines’ most consistent partners in condemning Chinese actions in disputed waters while backing Philippine maritime capacity-building. (abs-cbn.com) ### What has Japan already done for the Philippines at sea? Japan and the Philippines said in an April 29, 2025 summit that they would move ahead with implementation of their Reciprocal Access Agreement and begin negotiations on an Acquisition and Cross-Servicing Agreement. The two sides also said they would deepen cooperation on maritime safety through base development, capacity-building support and joint training with the United States. (scmp.com) Rappler reported that Japan has supplied patrol vessels, radar and surveillance-related support to the Philippine Coast Guard and maritime agencies in recent years. That assistance has made Japan one of Manila’s most important security partners outside its treaty alliance with Washington. ### Why are energy and trade on the agenda too? Marcos said Japan had been reliable “such as today’s ongoing oil crisis,” linking the visit’s economic side to energy security as well as defense. (japan.kantei.go.jp) Philippine officials said the Tokyo program includes talks with business leaders and efforts to attract investment alongside government-to-government meetings. (rappler.com) The Manila Times and other Philippine outlets reported that energy resilience, trade and investment were expected to feature prominently in Marcos’ talks with Japanese counterparts. That reflects Manila’s effort to widen the visit beyond maritime disputes and secure support in sectors tied to growth and fuel supply. ### How does this fit into the Philippines’ wider strategy? (pco.gov.ph) Japan’s foreign ministry said Marcos has visited Japan multiple times since taking office, and both governments have steadily upgraded defense and economic coordination. The April 2025 Japan-Philippines summit also explicitly described both countries as U.S. allies sharing values such as the rule of law and committed to a “Free and Open Indo-Pacific.” (manilatimes.net) The current visit adds a ceremonial layer to that trend. Rappler said it is the first state visit by a Philippine president to Japan in more than a decade, while Japanese officials have cast it as an opportunity to deepen bilateral cooperation further. Marcos’ next major public events are his summit with Takaichi and any agreements announced before he leaves Japan on May 29. (rappler.com) (mofa.go.jp)
