Japan Just Armed the Philippines — Beijing Is Furious About It

Added: 2026-05-23

[00:00:04]A new warship has just entered the water and it is not just any warship. This is the JS Natori, Japan's newest stealth frigate commissioned yesterday at the Mitsubishi Heavy Industries shipyard in Nagasaki, Japan. 132 m of grey steel, a radar evading hull, anti-submarine weapons and a crew of 90 sailors ready to deploy. But here's the question nobody is asking loudly enough.

[00:00:29]Why does this ship matter to the Philippines and why is Beijing already watching? And this is not just about Japan building more warships. This is about a region that is quietly, but very deliberately preparing for something.

[00:00:42]Stay with us. Let us start with the ship itself. The JS Natori, [music] hull number FFM 9, is the ninth vessel in Japan's Mogami class frigate program.

[00:00:52]She was built entirely by Mitsubishi Heavy Industries at their Nagasaki shipyard and formally handed over to Japan's Maritime Self-Defense Force in a ceremony on the 21st of May. The Mogami class is what naval analysts call a multi-mission stealth combatant. She is designed from the waterline up to be hard to detect on radar. The whole lines are smooth, the superstructure is angled, she carries almost no external clutter that would give away her position on an enemy screen. At 3,900 tons standard displacement, she is not the biggest ship in the water, but she is one of the smartest. She carries an OPY-2A radar, one of the most advanced surface search and tracking systems in service anywhere in the Indo-Pacific today. She has a full anti-submarine warfare suite including variable depth sonar. She carries unmanned underwater vehicles and unmanned surface vehicles directly on board and she is armed with a BAE Systems 5-in naval gun and a full missile weapons package. [music] Her top speed is over 30 knots for mission surveillance, patrol, and combat readiness in Japan's southwestern island chain and the East China Sea. Now, the JS Natori is the ninth of 12 planned Mogami-class frigates. Eight are already deployed, three more are coming before the year is out, but Japan is not stopping at 12. Tokyo has already ordered a new upgraded class, 12 more ships with enhanced weapons and electronics to be built between now and 20 28. And here is where it gets interesting. That upgraded design has been ordered not just by Japan, but by the Royal Australian Navy as well. Japan is now an arms exporter. That is a major shift for a country that for decades after World War II had strict constitutional restrictions on weapons [music] transfers. Those days are over.

[00:02:45]Japan has doubled its defense budget and has launched an official security assistance program, sending equipment and funding to partners across Southeast Asia. [music] And its frigates are now sailing, training, and operating in waters far beyond Japanese shores. Now, let us connect this directly to the Philippines because this is the story within the story. Do say 3 months ago in February of this year, the combined armed forces of Japan, the Philippines, and the United States conducted a multilateral maritime cooperative activity inside the Philippines exclusive economic zone. Deep in the South China Sea, Japanese warships, Filipino frigates, American destroyers, operating together, drilling together, and sending a message together. That is not a coincidence, that is a pattern.

[00:03:31]Japan has been steadily donating patrol vessels and Coast Guard equipment to Manila for years. In January, Tokyo pledged a $6 million security assistance package specifically to build naval facilities for Philippine patrol boats.

[00:03:45]The two countries have also signed a reciprocal access agreement, which allows each country's military forces to enter the other's territory for joint combat training. Japan and the Philippines training on each other's soil. That has never happened before in the modern era. Japan's Chief of Naval Staff visited Manila as recent lie as April, just weeks before the JS [music] Notorious commissioning. And during this year's Balikatan exercises, the major annual war games between the Philippines and the United States, Japan did not just observe, Japan participated with ground troops alongside warships for the first time. One analyst put it plainly, Japan now participates with ground troops in addition to warships, indicating a rising possibility of joint United States, Japan, and Philippines responses to South China Sea conflicts.

[00:04:35]Let that sentence sit for a moment.

[00:04:37]Joint responses, not just exercises, responses. Beijing is watching all of this, and it is not staying quiet. When Japan announced its security assistance package to the Philippines, Chinese state media accused >> [music] >> Tokyo of using Manila to justify remilitarization. Beijing even invoked Japan's wartime history, referring to what it called Tokyo's wartime blood debt to Manila. That is a significant escalation of language. China has also ramped up its own activities, Wally, on the water. In January, days after United States and Philippine forces exercised at Scarborough Shoal, the PLA Southern Theater Command conducted air and naval patrols around the disputed area. And unusually, they publicly announced the details. Flight paths, aircraft types, naval frigates deployed, that is not normal procedure. That is a deliberate message. The picture emerging is one of two competing visions for the South China Sea. One where China asserts dominance through presence and sustained pressure. And one where Japan, the Philippines, the United States, and increasingly Australia form a layered network of alliances, exercises, and hardware transfers designed to push back. The JS Natori is one piece of that second vision. So, where does this leave us? Japan has commissioned its ninth stealth frigate. Three more are coming before the year is out. A new class of 12 upgraded ships is already on order, and the Maritime Self-Defense Force is deepening operational ties with the Philippines at a pace that would have seemed unthinkable a decade ago. The JS Natori is named after a river in northern Japan, but her mission and the mission of every ship in her class is pointed firmly south and west towards the East China Sea, towards the Philippine Sea, towards the waters where the next major flash point in Indo-Pacific security is most likely to occur. This is not about one frigate.

[00:06:31]This is about Japan deciding clearly, deliberately, and with real money that it will no longer sit on the sidelines of regional security. And for the Philippines, which has been facing Chinese pressure at sea almost every week, a partner like Japan with warships, funding, and political will is exactly what Manila has been asking for.

[00:06:51]What makes this class of ship particularly significant is something that does not always make the headlines, and that is how few people it takes to run her. The Mogami class operates with a crew of roughly 90 sailors. To put that I in perspective, Japan's older destroyer-type vessels require more than 230. That is not a small difference.

[00:07:11]That is a fundamental rethinking of how a modern navy goes to sea. These ships are heavily automated. They are built for a Japan that has a shrinking population, a tight defense budget, and a growing list of maritime responsibilities. The frigates are designed to be operated by remarkably small crews, helping the JMSDF do far more with far less. And that philosophy, more capability, less manpower, lower cost per hull, is exactly why allies like Australia are looking at this design and saying, "We want this too."

[00:07:43]What is also worth understanding is that Japan has not just been building ships, it has been building an entirely new command structure to go with them. At the end of March 2026, the JMSDF implemented a major organizational reform establishing a new patrol and defense group and assigning its most modern surface combatants including the Mogami class FRS I gates to this formation. This is not administrative paperwork. This is Japan creating a dedicated force built around these exact ships whose primary peacetime mission is surveillance and monitoring of foreign naval vessels in waters surrounding Japan. In recent years, the rapid expansion of the People's Liberation Army Navy has led to a marked increase in the frequency and scale of Chinese naval activities near Japan compelling the JMSDF to deploy not only destroyers, but also missile boats, replenishment ships, and even minesweepers to meet the growing demand for maritime domain awareness. The JS destroyer does not just join a fleet, she joins a new unit with a new mission built specifically for this moment in history.
