Japan's then main opposition Liberal Democratic Party's (LDP) leader and former Prime Minister Shinzo Abe speaks to voters atop a campaign van at Akihabara electronics store district in Tokyo, in this file picture taken December 15, 2012, on the last election campaign day ahead of the general election. Abe's first politically risky step of declaring the country's intent to join talks on a U.S.-led Pacific Rim free trade pact appears to be paying off as his record high ratings edge even higher.
