Japan will deploy upgraded long-range antiship missiles to its southernmost main island this month, a move analysts say underscores Tokyo’s growing effort to strengthen defenses against threats from China and North Korea.
The Type-12 surface-to-ship missile will deploy March 31 to Camp Kengun on Kyushu, according to a news release Monday from Japan’s Ministry of Defense.
Security analysts say the deployment reflects Japan’s push to expand its military capabilities while remaining within the bounds of its pacifist constitution.
The move is a “symbolically important step” as Tokyo increases its defense capabilities alongside Washington and Manila, said Mark Davidson, a former director of the U.S. Global Counterterrorism Communications Center and a professor of international politics at Temple University’s Japan Campus.
Recent developments across the region show allied militaries strengthening their ability to counter Chinese naval forces along the First Island Chain, which stretch from the Kuril Islands to Borneo and include Japan, Taiwan and the northern Philippines.
The Philippine marine corps introduced its BrahMos missile system in November. U.S. Marines deployed the Navy-Marine Expeditionary Ship Interdiction System, known as NMESIS, to Japan’s Ishigaki Island near Taiwan in September and to the Philippines in April.
The U.S. Army also fired its Typhon missile system during last year’s Talisman Sabre drills in Australia.
Together, these steps represent a “synchronized series of capability upgrades among the three militaries that will allow joint defense of the First Island Chain and denial of sea access to the Chinese Navy,” Davidson wrote in an email Tuesday.
The upgraded Type-12 missile has a range of roughly 620 miles, compared with about 62 miles for its predecessor, the Type-88. From Kyushu, the upgraded weapon could reach parts of China’s coastline and North Korea.
Beijing disputes Tokyo’s control of the Senkaku Islands in the East China Sea, while Pyongyang continues to expand its ballistic missile and nuclear weapons programs.
Former U.S. Navy officer Luke Collin, a principal at the Asia Group advisory firm in Washington, D.C., described the missile deployment as a stabilizing development.
“Japan has interpreted its constitution as permitting the maintenance of Self-Defense Forces for national defense, and this capability is part and parcel of that,” he wrote in an email Wednesday.
The Type-12’s standoff capability could deter attempts to alter the status quo around Taiwan, said Junjiro Shida, a senior associate professor of international politics at Meio University in Nago city.
Beijing has said it will reunify self-governing Taiwan with mainland China, by force if necessary.
“The Japanese government has strengthened its stance of first contributing to its own stability and the stability of the region through its own efforts,” Shida said in an email Tuesday.
The move will “ultimately lead to the strengthening of the Japan-U.S. alliance,” he added.
Officials say additional missile moves are planned. Another Type-12 unit is expected to deploy to Japan’s Camp Fuji, about 3 miles north of the Marine Corps’ Combined Arms Training Center Camp Fuji, for training by March 2028, according to documents released in August by Japan’s South Kanto Defense Bureau.
High-velocity gliding missiles designed for island defense are also expected to be stationed at the camp beginning March 31, a bureau spokesman said by phone Wednesday.
Some Japanese government officials may speak to the press only on condition of anonymity.
