(AP Photo/J. Scott Applewhite) (Newser) – Japan is getting another big-name ambassador from the US. Caroline Kennedy's name had been floated for the post; now she's got the job, the Washington Post reports. She follows in a line of famous ambassadors to the island nation, including former VP Walter Mondale and former Senate majority leader Mike Mansfield. Kennedy was a key supporter of President Obama during his first campaign, the Post notes. Her husband, Edwin Schlossberg, reportedly won't be making the full-time move to Tokyo.
