Shinzo Abe called snap elections last month, hoping to have a stronger mandate to go ahead with his economic agenda, also known as Abenomics.
He has pledged to revive the economy with a mix of loose monetary policy, government spending and reforms, while moving ahead with plans to rein in Japan's massive public debt.
Abe strongly believes that Abenomics will be successful, insisting it is the only way out.
But will Japanese voters back him in Sunday's poll? Is Abenomics able to help their economy? And why did Abe called snap elections in the first place?
