IWAKUNI, Yamaguchi Pref. -- A majority of Iwakuni residents voted "no" in a closely watched plebiscite Sunday, rejecting the central government's plan to move 57 U.S. warplanes and 1,600 additional marines to the area, according to partial vote counts and exit polls.

According to Iwakuni City Hall, 21,000 residents had voted "no" and 3,000 "yes" as of 10:30 p.m. Sunday, with 48.31 percent of the votes counted.

The Iwakuni plebiscite was the first held since Japan and the United States agreed to restructure U.S. bases last October. Although the result is nonbinding, the vote was closely watched by leaders in both countries.
