Japan ’s Defence Ministry has said it plans to deploy surface-to-air missiles on Yonaguni Island, a remote western outpost close to Taiwan, by March 2031, marking the first time a firm timeline has been announced for the proposal under discussion since 2022.
Defence Minister Shinjiro Koizumi said preparations were still underway, but the government was working toward the 2031 target. The unit will field medium-range missiles with a range of about 50 km, 360-degree coverage, and the ability to track up to 100 targets, aimed at intercepting aircraft and incoming missiles.
Yonaguni Island is strategically located and sits at the southwestern edge of Japan’s territory, close enough to Taiwan to see its coastline on a clear day. This marks the first time officials have committed to a specific deployment deadline, although Japan first announced plans in 2022 to enhance Yonaguni’s defences.
Yonaguni currently hosts around 160 personnel tasked with coastal surveillance, and local residents have raised concerns about being drawn into a regional conflict, prompting the government to plan briefings for the island’s population. The island’s militarisation and deployment of missiles is likely to further complicate Japan ’s already strained ties with China, as Tokyo increasingly shifts its strategic focus from Russia to China amid heightened Chinese military activity near Taiwan.
Beijing, which claims Taiwan as its territory, has warned against any external involvement.
“Japan must fully repent for its war crimes, immediately stop its wrong and provocative statements and moves that interfere in China’s internal affairs, and stop playing with fire on the Taiwan question,” China’s Foreign Ministry said in response, as reported in Al Jazeera.
China subsequently discouraged travel to Japan. Chinese visitors contribute roughly $11bn annually to Japan’s economy.
Tensions have also been fuelled further by remarks from Prime Minister Sanae Takaichi about the possible deployment of Japan’s Self-Defence Forces in a Taiwan contingency, comments she has refused to withdraw despite Chinese protests and retaliatory measures.
