A U.S. government spokeswoman denied Tuesday that Washington will consider revising a bilateral agreement on the operations of U.S. military facilities in Japan as sought by Okinawa.

"The U.S. has not agreed to and will not consider" opening the Status of Forces Agreement to renegotiation, State Department spokeswoman Marie Harf told reporters, referring to a call by Okinawa Gov. Hirokazu Nakaima for such a revision.

The governor of the southern Japanese prefecture, which hosts the bulk of U.S. military facilities in Japan, repeated his call earlier in the day in Tokyo as he faces a difficult decision on whether to authorize landfill work necessary to relocate a key local U.S. base.
