Mr Abe came to power last December vowing to drag Japan out of 20 years of stagnation.
He launched a risky and aggressive stimulus plan designed to push down the value of the Japanese yen and boost exports.
To keep Japan growing Mr Abe must implement painful and unpopular structural reforms, raise taxes and open Japan's economy to more competition.
Sunday's election victory will give him the power to do so. As the BBC's Rupert Wingfield-Hayes reports, the question is whether he has the will.
