The Liberal Democratic Party (LDP) of Shinzo Abe has won the general election in Japan, according to exit polls.
The party, which enjoyed almost 50 years of unbroken rule until 2009, is projected to have an overall majority in the new parliament.
Mr Abe has already served a Japan's Prime Minister between 2006 and 2007.
He has campaigned on a pledge to end 20 years of economic stagnation in Japan, and has promised a more assertive foreign policy towards China.
The governing Democratic Party (DPJ) of Yoshihiko Noda has lost support over its move to double sales tax, something he said was necessary to tackle Japan's massive debt.
The party has struggled since coming to power in 2009. Two prime ministers came and went before Mr Noda as the party struggled to deliver amid the economic downturn and 11 March 2011 earthquake and tsunami.
Mr Abe has promised more public spending, to make Japanese people again proud of themselves and to allow nuclear energy a role to play in resource-poor Japan's future despite last year's nuclear disaster at Fukushima.
Mr Abe has also called for a tough stance on the territorial row with China over East China Sea islands that both countries claim.
