In this Nov. 8, 2009 file photo, Okinawans shout slogans during a rally, protesting against the relocation of Futenama Marine Corps Air Station in Ginowan on the southern island of Okinawa, Japan. The deepening debate over the future of the major U.S. Marine base on Okinawa has opened a broad rift in Washington's most important alliance in Asia ahead of President Barack Obama's visit to Japan Friday, Nov. 13, and Saturday, Nov, 14. The banner reads: 'Withdraw the new base construction in Henoko. Oppose relocation within the prefecture (state).' (AP Photo/Kyodo News, File)
