The Japanese Communist Party adopted a new platform on the final day of its convention Saturday, dropping its calls for a "socialist revolution" and effectively putting to rest the party's opposition to the Emperor system.

All but one of the 1,006 delegates to the convention, which is held every three years, voted for the new platform, the first major change to the party's program since 1961.

According to party officials, it is the first time since the 1961 convention that anyone had clearly voted against proposals put forward by the leadership.
