Tokyo: Japan has conducted a military drill apparently aimed at bolstering defence of islands at the center of a territorial dispute with China.
The Defense Ministry says it was the first time the annual drill, held today near Tokyo, was aimed at island defence.
Defense Minister Itsunori Onodera said Japan must improve its military tactics in light of the dispute with China.
He said Chinese aircraft and sea vessels have infringed upon Japanese territory in waters and airspace around the disputed East China Sea islands, called Senkaku in Japan.
China also claims the islands, calling them Diaoyu. The Japanese government`s purchase of the islands in September triggered violent anti-Japan protests across China.
Japanese Prime Minister Shinzo Abe has said his government will increase defence spending to strengthen defence of the islands.
