Japan Joins Allies in Major Maritime Drill as Tensions Rise in the Region

Japan’s Self‑Defense Forces took part in a high‑profile joint maritime exercise on Wednesday alongside forces from the United States, Australia and the Philippines, marking a significant moment in the region’s expanding security cooperation. During the drill, Japan conducted a live demonstration using its coastal‑defense capabilities, striking a decommissioned Philippine Navy vessel in waters facing the disputed South China Sea.

The exercise unfolded as Manila and Tokyo opened formal discussions on a potential transfer of defense equipment talks made possible after Japan lifted long‑standing restrictions on military exports. Japan’s Defense Minister Shinjiro Koizumi said the discussions include the possible early transfer of naval vessels and training aircraft to the Philippines.

Philippine Defense Secretary Gilberto Teodoro and Koizumi observed the live‑fire portion of the drill on the ground, while President Ferdinand Marcos Jr. monitored the exercise via live feed from military headquarters in Manila. The president’s office said the event demonstrated the growing ability of the Philippine Armed Forces to operate seamlessly with international partners in support of regional security and freedom of navigation.

According to the Philippine military, two volleys were launched during the drill, striking the target vessel within minutes. The exercise took place roughly 75 kilometers off the coast of Paoay in northern Philippines, an area that faces the South China Sea. Officials said Japan’s coastal‑defense system is designed to help deter maritime threats and protect vulnerable shorelines.

Teodoro praised the successful demonstration, saying it marked an important milestone in the country’s expanding defense partnerships. The drill formed part of the annual “Balikatan” exercises a long‑running series of war games between Manila and Washington that this year includes active participation from Japan, Canada, Australia, France and New Zealand for the first time.

Earlier this month, Filipino and American troops also deployed a coastal‑defense system in Batanes, near Taiwan, amid ongoing tensions surrounding the self‑governed island.

More than 17,000 personnel are taking part in this year’s Balikatan exercises, including around 1,400 from Japan and 10,000 from the United States. Beijing has repeatedly criticized Manila’s growing military cooperation with its allies, arguing that such activities heighten regional tensions.
