Caroline Kennedy, the daughter of slain President John F. Kennedy, has been sworn in as U.S. ambassador to Japan.
Secretary of State John Kerry hosted a swearing-in ceremony Tuesday afternoon at the State Department and is to make remarks later at a reception at the Japanese ambassador's residence in Washington.
Caroline Kennedy, who was endorsed by the Senate last month, was nominated for the ambassador's job by President Barack Obama after playing a role in his re-election campaign.
Japan is the United States' fourth-largest trading partner and home to the Navy's 7th Fleet and 50,000 American troops. Kennedy's father battled Japanese forces as a Navy officer in World War II.
Caroline Kennedy was five days shy of her sixth birthday when her father was assassinated on Nov. 22, 1963.
