Japan plans to deploy surface-to-air missiles to its remote western island near Taiwan by March 2031, its defence minister said, as regional tensions simmer.
It is the first time that Japan specified a timeline for the missile deployment to Yonaguni island since it was announced in 2022.
China claims self-ruled Taiwan as its own and has not ruled out the use of force to “reunify” with it. Yonaguni is visible from Taiwan’s shores on a clear day, located just 110km (68 miles) away.
Tensions between Tokyo and Beijing have run high since November when Japanese Prime Minister Sanae Takaichi appeared to suggest that Japan would activate its self-defence force in the event of an attack on Taiwan.
The worry has long been that any attack on Taiwan, which counts the US as an ally, could result in a direct military conflict between Washington and Beijing, then widen to include other US allies in the region such as Japan.
Takaichi’s remarks to parliament plunged ties with China to their lowest level in years and Beijing has been piling on the pressure in a wide range of ways – sending warships, throttling rare earth exports, curbing Chinese tourism, cancelling concerts and even reclaiming its pandas.
Japanese defence minister Shinjiro Koizumi announced the timeline for the missiles on Tuesday, a day after China imposed export curbs on 20 Japanese companies and entities, citing national security concerns.
Koizumi said the Yonaguni unit will be equipped with medium-range surface-to-air missiles able to intercept incoming aircraft and missiles.
With a range of about 50km and 360-degree capability, the Japanese-made missile system can track up to 100 targets simultaneously and engage up to 12 at once.
China has yet to react to Koizumi’s announcement. But when Koizumi visited Yonaguni in November, Beijing said Japan was moving to “create regional tension and provoke military confrontation”.
Within days, China flew drones near the island to express its anger, prompting Japan to scramble aircraft jets in response.
The latest developments come after Takaichi secured a landslide victory in parliamentary elections earlier this month. That victory gave Takaichi political space to double down on boosting Japan’s defence capabilities.
