Emerging as the big winner in the Lower House election, Prime Minister Shinzo Abe declared Monday he has a renewed mandate to continue his policies and pursue his agenda — despite the lowest voter turnout on record.

On Sunday, Abe's conservative Liberal Democratic Party and its junior ruling coalition partner, Komeito, won 325 of the 475 seats and secured more than two-thirds of the powerful chamber for a supermajority.

In a news conference Monday afternoon, Abe vowed to pursue "Abenomics" — his economic policy based on the three "arrows" of aggressive monetary easing, more fiscal spending and structural reforms — that he says will raise Japan's long-term growth potential.
