Japan, the United States, and the Philippines have convened coast guard drills off Japan’s southwest coast to simulate real-world maritime emergencies—including vessel collisions—amid growing concerns over China’s maritime assertiveness. These high-profile exercises mark a significant escalation in trilateral cooperation as regional tensions rise over contested waters.
This joint operation underscores the three nations’ commitment to maritime security and freedom of navigation in the Indo-Pacific, signaling a robust response to Beijing’s recent naval activity across the first and second island chains.
Key Takeaways
Three-way coast guard exercises simulate vessel collision, fire control, and man‑overboard response
Dozens of personnel from Japan, US, and Philippines participated in drills near Kagoshima
The exercise reflects growing coordination against regional threats, notably Chinese maritime maneuvers
This marks the second major coast guard exercise after initial drills in the Philippines in 2023
Japan’s coast guard leadership emphasized contributing to a “free and open” Asia‑Pacific security order
Origins and Scale of the Joint Drills
Preceded by a similar trilateral drill in the Philippines last year, the latest exercises bring together coast guard units and maritime personnel to train for high-risk scenarios—especially collisions at sea, vessel fires, and rescue operations. Held off Kagoshima, the week-long drills tested interoperability and decision-making under duress.
Participants reported realistic simulations designed to mirror possible incidents in busy or disputed waters, ensuring readiness for fast response when lifelines are at stake.
Strategic Context: China’s Naval Ambitions
These drills unfold against a backdrop of increased Chinese naval activity near Japan and the Philippines. China has been deploying its carriers Shandong and Liaoning simultaneously in the western Pacific and conducting air-sea patrols in the South China Sea—raising alarm across the region.
Tokyo officials emphasized that persistent Chinese military presence near disputed islets—such as the Diaoyu/Senkaku islands and maritime areas claimed by both Beijing and Manila—elevates the risk of accidents and escalations. These drills, though not publicly focused on China, are clearly aimed at bolstering regional defense capabilities.
Why Coast Guard Cooperation Matters
Maritime safety in focus: The drills replicate realistic threats—collision avoidance, fire suppression, OSRO (overboard rescue operations).
Interoperability boost: Joint drills enhance coordination among coast guard services, enabling joint responses across jurisdictions.
Deterrence signal: Operating together visibly strengthens deterrence and signals resolve to potential aggressors.
Civilian-to-military pipeline: Coast guard forces serve as a bridge between civilian maritime duties and national defense, reinforcing layered security.
The Philippines’ Role in Regional Security
The Philippines has solidified defense ties with both Japan and the US. Japan’s 2024 Reciprocal Access Agreement with Manila allows mutual support in crisis scenarios. Manila also participates in Balikatan military exercises with the US and recently signed a visiting‑forces pact with New Zealand—all in response to assertive Chinese behavior near Sandy Cay and Scarborough Shoal.
Regional Reactions and Implications
Public statements emphasized that the drills were not pointed at any specific country. Yet expert commentary noted such language often alludes to China’s sweeping maritime moves. Analysts agree these drills enhance situational awareness and strengthen front-line capabilities to support smaller nations in a crisis.
What Comes Next
Anticipate further trilateral exercises extending to military-level coordination across sea, air, and cyber domains. The coast guard drills are likely a prelude to more expansive operations under Balikatan and Philippine–Japan frameworks. Combined naval exercises and patrol missions will likely be employed to reinforce a rules-based maritime order.
Conclusion
The Japan–US–Philippines coast guard drills are more than routine maritime exercises—they symbolize a strategic pivot toward deeper security cooperation in response to China’s expanding maritime influence. By simulating real emergencies and boosting interoperability, the trilateral partnership strengthens regional deterrence and affirms a shared vision of a free and open Indo‑Pacific.
