TOKYO - Japan's military is to station four unarmed missiles on an island that sits on the gateway to the Pacific, officials said on Thursday, for a major drill that has made China nervous.
The exercise, aimed at bolstering defence of Japan's southern islands, has already seen a launching system and a loader for Type-88 surface-to-ship missiles installed on Miyako island.
"This is the first time" that missile systems have been taken to Miyako, said a spokesman for the Joint Staff of the Self Defence Forces, adding that the missiles could not be fired in their present state.
"The drill is designed for the defence of islands," he said.
While the Japanese military makes no secret of the fact these missiles are not operable, observers say their deployment serves to remind anyone watching of Japan's capabilities.
The missiles were expected to arrive later Thursday and it was not clear how long they would stay for.
The Self Defense Forces began their 18 days of war games on November 1, with 34,000 military personnel, six vessels and 360 aircraft.
The exercise comes amid growing nervousness in Japan and other parts of Asia over China's surging military might, which has seen it expand its naval reach into the Pacific Ocean as it squabbles with Tokyo over the ownership of islands in the East China Sea.
It also has separate disputes with numerous countries over competing claims to territories in the South China Sea, which China claims as virtually all its own.
Chinese naval assets stationed in the north of the country are somewhat hemmed in by the chain of Japanese islands that separate the East China Sea and the Pacific. The strait between Miyako and the main island of Okinawa offers one of the few direct access points.
