The move of some 7,000 U.S. marines from Okinawa island to the U.S. territory of Guam is part of a broader plan to streamline the 50,000 U.S. forces based in Japan and give Japan's military greater responsibility for security in the Asia-Pacific.
The U.S. has estimated the total cost of relocation at $10 billion, a Defense Agency spokesman said on condition of anonymity, citing agency policy.
Washington has reportedly told Tokyo that the relocation, which would reduce some of Okinawa's burden in hosting American forces, would take decades unless Japan chips in a significant amount. The United States wants Japan to pay 75 percent of the cost, more than twice as much as the $3 billion Tokyo has offered to pay -- mostly in the form of loans for U.S. companies to cover the cost of the move -- according to media reports.
American troops have been stationed in Japan since the end of World War II in 1945.AP
