Japan Defense Chief Visits Philippines, Eyes Expanded Military Cooperation

Manila— Japan’s Defense Minister Shinjiro Koizumi visited the Philippines on Tuesday to attend joint military exercises and hold talks with Philippine leaders, as the two US allies seek to deepen defense ties amid rising regional tensions.

Koizumi met Ferdinand Marcos Jr. in Manila, alongside Defense Secretary Gilberto Teodoro Jr., with discussions expected to include potential transfers of used Japanese naval vessels to the Philippines, officials said.The visit comes as both countries expand security cooperation under a 2024 Reciprocal Access Agreement that allows their forces to conduct large-scale joint exercises.

The pact has enabled Japan to deploy around 1,400 personnel to regularly participate in the annual Balikatan drills alongside US and Philippine forces.Koizumi is scheduled to join representatives from 16 countries observing a key exercise in Paoay, where allied forces will conduct a live-fire drill simulating an attack on a decommissioned warship off the coast. Japanese forces are expected to fire Type 88 missiles as part of the operation.

The drills, involving US, Japanese, Canadian and Philippine forces, are aimed at strengthening interoperability and deterring growing maritime assertiveness by China in the region, particularly in the contested South China Sea.Officials said Japan’s recent policy shift lifting restrictions on lethal weapons exports could allow the transfer of up to six Abukuma-class destroyers to the Philippines, though details remain under discussion.

Before arriving in Manila, Koizumi visited Jakarta, where he signed a defense cooperation agreement with Indonesian authorities, reflecting Tokyo’s broader effort to build a network of security partnerships in Asia.China has criticized Japan’s evolving defense posture, warning against what it described as moves toward militarization, while US and regional allies have welcomed Tokyo’s expanded role in regional security.
