Japan's defence ministry on Friday said it scrambled jet fighters to monitor Chinese air force bombers and drones flying near the country's southwestern Okinawa island and Taiwan.
Two Chinese H-6 bombers were spotted flying through the strait between southwest Japan's Okinawa and Miyako islands connecting the East China Sea and the Pacific on Friday morning, the ministry said.
Okinawa is home to one of the major American military bases in Asia-Pacific and the centre of Japan and the United States' defence buildup to deter China from attacking Taiwan or nearby Japanese islands.
In a separate statement, the ministry said it also spotted a Chinese military drone and another "likely Chinese" drone flying between Japan's westernmost Yonaguni island and Taiwan during the day.
Japan dispatched its Air Self-Defense Force jet fighter to follow the drones, which eventually turned toward mainland China, it said.
