U.S. Ambassador to Japan John Roos will represent the United States on Friday at the annual ceremony in Nagasaki commemorating the anniversary of city's atomic bombing in 1945, the U.S. embassy in Tokyo said Wednesday.
Roos, whose term will end shortly, attended the Nagasaki ceremony for the first time last year. In 2010 he became the first U.S. ambassador to attend Hiroshima's memorial ceremony, doing so again last year and on Tuesday.
Announcing Roos's attendance, the embassy said in a statement the United States "looks forward to continuing to work with Japan to advance President (Barack) Obama's goal of realizing a world without nuclear weapons."
