Could Philippines-Japan air force exercise herald Tokyo’s closer involvement in Southeast Asia?
- An analyst says such a prospect would have been ‘unthinkable’ two decades ago following Japan’s legacy of conquest and occupation in the region
- But Manila and Tokyo say the exercise is a sign of deepening defence ties – as they face pressure from an increasingly assertive Beijing

The four-day exercise that ended on Thursday saw teams from the Philippine Air Force and the Japan Air Self-Defense Force (JASDF) train for humanitarian and disaster relief operations at Clark Air Base north of Manila. Philippine Air Force spokesperson Lieutenant Colonel Maynard Mariano told This Week in Asia the activity was originally meant to feature in-flight training, with a 10-man JASDF team and a Philippine crew each flying a C-130 Hercules transport plane.
But this plan was scrapped after the July 4 crash of a C-130, the Philippines’ worst military air disaster since World War II, saw the local authorities ground all such aircraft. The activity was then turned into a series of tabletop exercises, which involved ground training as well as discussions and planning for a simulated emergency scenario.
According to the Japanese embassy in Manila, the activity was the first-ever joint exercise between the two air forces and a “further sign of deepening defence ties between the two countries”.
“Japan reiterates the importance of maintaining a free and open Indo-Pacific which is inclusive and based on the rule of law, democratic values, territorial integrity, transparency, and peaceful resolution of disputes,” the embassy said in a press release.
