Japan opens radar station manned by 160 troops close to disputed East China Sea islands
Japan on Monday switched on a radar station in the East China Sea, giving it a permanent intelligence gathering post close to Taiwan and a group of disputed islands claimed by both Tokyo and Beijing.
The new Self Defence Force base on Yonaguni is at the western extreme of a string of Japanese islands in the East China Sea, 150km south of the disputed islands known as the Senkaku islands in Japan and the Diaoyu in China.
A unit of about 160 SDF members on Yonaguni Island is manning the radar station, monitoring both ships and aircraft.
“This radar station is going to irritate China,” said Nozomu Yoshitomi, a professor at Nihon University and a former major general in the Self Defence Force.

The deployment fits into a wider military build up along the island chain, which stretches 1,400km from the Japanese mainland.
