Japan to Deploy Missiles on Island Near Taiwan by 2031

Tokyo: Japan has announced plans to deploy surface-to-air missiles on Yonaguni, its westernmost territory, located about 110 km from Taiwan, by March 2031 as part of a broader effort to strengthen its air defences.

Deployment Timeline

Defense Minister Yasukazu Hamada said the deployment will be carried out during fiscal 2030, with completion expected by March 2031, though the exact timing could be adjusted depending on progress with necessary facility construction.

Missile Details and Strategic Purpose

The missiles — medium-range surface-to-air systems designed to intercept aircraft and ballistic threats — will be positioned on Yonaguni to bolster Japan’s defensive posture in the East China Sea amid growing concerns over China’s military activity in the region.

Background on Defence Plans

Japan first outlined plans in 2022 to enhance defences on its remote southwestern islands, which are closer to Taiwan and strategic sea lanes, reflecting a shift in focus as regional security dynamics evolve. Authorities also plan to expand electronic warfare and surveillance units on the island ahead of the missile deployment.

Regional Tensions

The announcement comes amid heightened tensions between Tokyo and Beijing, which views Taiwan as part of its territory and has reacted strongly to Japan’s defence build-up and recent remarks by Japanese leaders about Taiwan’s security.

Local Engagement

Japan’s government and local officials are expected to brief Yonaguni residents in the coming weeks to explain the deployment plan and address local concerns about the island’s increasing militarisation.
