Japanese Prime Minister and ruling Liberal Demcratic Party President Shinzo Abe smiles during a press conference at the LDP headqharters on July 10, 2016 in Tokyo, Japan. Exit polls conducted on July 10 in a crucial Upper House election show the four parties that favor constitutional revision approaching the two-thirds threshold needed in that chamber to initiate an amendment. As voters went to the polls, the focus was on whether the four would win enough seats to reach the two-thirds majority in the 242-seat chamber needed for approval before an amendment could be put to a national referendum.
