REFILE - ADDITIONAL CAPTION INFORMATION Protesters wearing traditional hats bearing slogans participate in a mass rally against a U.S. base in Ginowan on Japan's southwestern island of Okinawa, about 1,600 km (1,000 miles) south of Tokyo, November 8, 2009. A dispute over a replacement facility for Futenma air base on Okinawa, a key part of a realignment of U.S. troops in Japan, has strained the alliance between the U.S. and Japan, ahead of U.S. President Barack Obama's trip to Tokyo next week. Okinawa currently hosts about half the 47,000 U.S. military personnel in Japan. The slogans on the hats read: 'Change a base into a park' (R) and 'Remove all bases'.
