South Korean law mandates that men who are arrested for prostitution solicitation must attend “john schools” in an attempt to lower repeat offenders.
In 2009, the number of men forced to attend the classes peaked at nearly 35,000.
In 2011, the number of men declined to 7,400. Criminal justice officials in South Korea believe that the decline in attendees is not because there are fewer men visiting prostitutes, but due to the difficulty in detecting prostitution.
A government report estimated that there were 147,000 prostitutes working in South Korea.
