YONAGUNI, Japan (Reuters) - Japan began its first military expansion at the western end of its island chain in more than 40 years on Saturday, breaking ground on a radar station on a tropical island off Taiwan.

The move risks angering China, locked in a dispute with Japan over nearby islands which they both claim.

Japanese Defense Minister Itsunori Onodera, who attended a ceremony on Yonaguni island to mark the start of construction, suggested the military presence could be enlarged to other islands in the seas southwest of Japan's main islands.

"This is the first deployment since the U.S. returned Okinawa (1972) and calls for us to be more on guard are growing," Onodera told reporters. "I want to build an operation able to properly defend islands that are part of Japan's territory."

Japan's defence minister said Sunday there have been an "abnormal" number of flights by Russian military aircraft close to Japanese islands in recent days.

The country's air defence force scrambled fighter jets for seven days in a row through Saturday after spotting Russian military planes flying along the Japanese archipelago, according to the defence ministry.

On Friday six Russian TU-95 bombers were seen flying two by two, with one pair moving around the Okinawan islands and then going north along Japan's Pacific coast.

The two other pairs flew over the Sea of Japan (East Sea). None of the flights intruded into Japanese airspace.
