Defense Agency chief Yoshinori Ono said Friday that Japan and the United States might not hold realignment talks next week if the two sides fail to agree on where to move the U.S. Marine Corps' Futenma Air Station in Okinawa.

Tokyo and Washington are still trying to reach an agreement and compile an interim report for the "two-plus-two" meeting of foreign and defense chiefs from the two countries scheduled for Oct. 29 in Washington, Ono said.

He said Tokyo would not insist on having the meeting if the two sides can't reach an agreement by Oct. 29.
