The Organization for Economic Cooperation and Development says South Korea allows long paternity leaves for fathers but few take the option.
 
According to the OECD Family Database 2015, South Korea had the longest paid vacation for fathers among member countries at 52-point-six weeks.
 
Japan had the second-longest at 52 weeks, followed by France at 28 weeks. The average was nine weeks.
 
But among some 76-thousand people who took parental leave in South Korea last year, only about three-thousand-400 were fathers. That's just four-point-five percent of the total.
 
In Iceland, almost 30 percent of fathers took parental leave. In Norway, 21 percent of dads took parental leave.
