The second day of the two-day early voting period began at 6 am local time (2100GMT Thursday).
More than 10 million out of 44.3 million eligible voters have cast their ballots so far, with turnout at 24.55% as of 11 am (0200GMT), according to the National Election Commission.
South Korea saw record early voting Thursday to elect a successor to former President Yoon Suk Yeol, who was ousted over his failed martial law bid in December, as 19.58% of voters cast ballots.
That marked the highest first-day turnout since nationwide early voting was introduced in 2014.
The election commission established 3,568 polling stations across the country for early voting.
The two-day early voting period will end at 6 pm local time Friday (0900GMT).
Currently, six hopefuls are vying for the country's top office, but the actual contest is between two candidates: Lee Jae-myung of the Democratic Party (DP) and People Power Party (PPP) candidate Kim Moon-soo.
The latest poll released Wednesday showed DP candidate Lee leading with 49.2%, followed by Kim of the ruling PPP with 36.8%.
Lee Jun-seok of the New Reform Party was third with 10.3%.
The presidential election is scheduled for June 3.
