Japan fired its first overseas missile in eight decades from Philippine soil on Thursday, launching a Type 88 surface-to-ship projectile at a decommissioned vessel in the South China Sea as part of the climactic phase of the largest joint military exercises the Philippines has ever conducted with the United States. The strike, which took place off the coast of Ilocos Norte in the northern Philippines, marked a watershed moment in Japan’s postwar military history and sent a sharp message to Beijing as China-watchers warned the region is entering a new phase of escalating tension.
The Japanese Type 88 missile struck its target in under six minutes, Defence Minister Shinjiro Koizumi said, describing the launch as a demonstration of the “unprecedented scale and complexity” of this year’s Balikatan exercises. Japan’s deployment of the missile system — the first time Tokyo has sent such hardware overseas since World War II — drew swift condemnation from Beijing, which accused Japan of stoking “neo-militarism” in the region and warned that the exercises risked destabilising the already volatile South China Sea.
The backdrop to Thursday’s live-fire demonstration is one of deepening friction between the Philippines and China over disputed maritime territory. Since the beginning of Balikatan 2026, which runs through May 8, Chinese coast guard and naval vessels have carried out a series of what Manila describes as “aggressive interference” operations near Philippine-held reefs and islands in the Spratly Chain. The most recent confrontation occurred on May 19 when the Philippine Coast Guard confronted a Chinese coast guard vessel near Zambales province, just weeks after a documented collision between Philippine and Chinese ships near Scarborough Shoal.
Thursday’s launch was not the only milestone in the exercises. A United States Army Typhon system fired a Tomahawk cruise missile that struck a target approximately 630 kilometres away — the first operational firing of the Typhon launcher since it was deployed on Philippine soil more than two years ago. Together, the Japanese and American strikes represented the most overt demonstration of the growing firepower integration between the three allies, and analysts said the message to Beijing was unambiguous.
“The message of the exercise is clear,” said Chris Gardiner, chief executive of the Canberra-based Institute for Regional Security. “‘Not today’ — now is not the time to use force against the Philippines or to change the status quo around Taiwan.” The First Island Chain, of which Japan, the Philippines and Taiwan form the backbone, is considered the critical geographic line for containing Chinese maritime expansion into the Pacific.
Balikatan 2026 has drawn an unprecedented coalition of forces, with approximately 17,000 troops from the United States, Japan, Australia, New Zealand, Canada, France and the United Kingdom taking part. Japan alone deployed around 1,400 personnel — its largest contingent since the exercises began — including the helicopter destroyer JS Ise, landing ship JS Shimokita, destroyer JS Ikazuchi, C-130H transport aircraft and the Type 88 missile battery. The exercises also featured Japan’s Amphibious Rapid Deployment Brigade operating on Philippine soil for the first time since the Second World War, a fact not lost on Beijing.
China’s Foreign Ministry said it had summoned Japan’s ambassador to lodge a formal protest, calling the missile launch a “deliberate provocation” that violated Japan’s own pacifist constitution. China’s Defence Ministry placed its People’s Liberation Army on heightened alert and ordered increased naval and aerial patrols throughout the South China Sea, including near the Second Thomas Shoal where a Philippine navy ship remains stationed under a longstanding resupply mission that has repeatedly triggered confrontations with Chinese vessels.
The exercises also tested new generations of mobile strike capabilities that Philippine military officials said could prove decisive in any future maritime conflict. Among the systems deployed were the Navy Marine Expeditionary Ship Interdiction System, the Marine Air Defense Integrated System and the High Mobility Artillery Rocket System, all designed to give Philippine forces greater reach and precision against adversary assets in contested waters. US Indo-Pacific Command said the drills had “stress-tested” interoperability between American, Japanese and Filipino forces in realistic conditions.
Defence Secretary Gilberto Teodoro Jr said the exercises were “purely defensive in nature” and designed to uphold international law and freedom of navigation in the South China Sea. “We are not seeking conflict, but we will not stand by while our sovereignty is challenged,” Teodoro said at a press conference in Manila. “The Balikatan exercises demonstrate unequivocally that the Philippines is not alone.”
Japan’s Koizumi is expected to travel to the Philippines on May 6 to observe the final phase of the exercises, including the sinking exercise off Laoag City near the South China Sea and Taiwan. Officials in Tokyo said the visit would further cement the reciprocal access agreement signed between the two countries last year, which for the first time allows Japanese troops to be stationed on Philippine soil. Vietnam and Indonesia, both of which have competing claims in the South China Sea, have watched the exercises closely, and analysts said therilitary show of force could reshape strategic calculations across Southeast Asia.
