Philippine President Ferdinand Marcos Jr arrives in Japan on Wednesday for a visit that is expected to pave the way for closer security ties with Tokyo, as Manila increasingly sides with the United States in its regional tussle with China.
Marcos and Prime Minister Fumio Kishida are expected to deepen cooperation in humanitarian assistance and disaster relief, a possible precursor to establishing a broader legal framework that would allow Japanese forces to deploy to the Philippines more easily.
"As the United States deepens its relationship with the Philippines, it's important for regional security that Japan join in," a Japanese defence ministry source with knowledge of internal discussions on national security told Reuters. He asked not to be identified because he is not authorised to talk to the media.
Marcos' first visit to Japan since taking office in July comes after he signed an agreement last week granting the United States greater access to its military bases. It also follows a trip to Beijing last month where he told his Chinese counterpart, Xi Jinping, that the Philippines would pursue an independent foreign policy.
"My bilateral visit to Japan is essential," Marcos said in a speech as he departed Manila. "It is part of a larger foreign policy agenda to forge closer political ties, stronger defence and security cooperation, as well as lasting economic partnerships with major countries in the region amid a challenging global environment."
Marcos said he will build collaboration on priority areas like agriculture, renewable energy, digital transformation, infrastructure, and defence and security.
That sentiment is shared in Tokyo, which has been deepening security ties with nations that view China with concern.
A year ago, Japan and Australia signed a visiting forces agreement, allowing them to deploy forces on each other's soil, with Tokyo concluding a similar accord with Britain last month. Those deals provide a framework for how Marcos and Kishida could also forge deeper military ties to counter a common adversary, say experts.
"The Philippines is a critical security partner for Japan," said Narushige Michishita, a professor at the National Graduate Institute for Policy Studies (GRIPS) in Tokyo. "Any conflict in the Taiwan Strait would make the Philippine Sea strategically important," he added.
Taiwan, which lies between Japan and the Philippines, has become a focal point of intensifying Chinese military activity that Tokyo and Washington worry could escalate into war as Beijing tries to capture what it views as a rogue province.
A Japanese military presence in the Philippines could also help Marcos counter Chinese influence in the South China Sea, much of which Beijing claims, including territory that Manila considers its own.
Beijing has said its intentions in the region are peaceful.
Marcos has vowed not lose an inch of territory in the strategic waterway, through which $3 trillion in ship-borne trade passes annually.
By gaining access to bases in the Philippines, Japan would extend the range of its defence forces, including surveillance aircraft that could patrol the South China Sea, according to Ken Jinbo, a professor at Keio University in Japan, who also served as a government security advisor.
"One thing people are watching out for during President Marcos' visit, is whether Japan will agree to provide infrastructure assistance now that the United States has access to the nine bases there," he said.
