Is Prostitution Legal in South Korea?

South Korea's main law is the Act on the Punishment of Arrangement of Commercial Sex Acts, in force since 2004. It defines 'sexual traffic' as intercourse or similar acts for money or other benefits. It covers both the seller and the person 'becoming a partner thereof', meaning the customer (Article 2). Either can face up to a year in prison, a fine of up to 3 million won, or a short detention or petty fine (Article 21). Arranging it carries up to three years, or seven when it's run as a business (Article 19).

On 31 March 2016 the Constitutional Court upheld Article 21 by six votes to three, so there's no legal opening even between consenting adults. Enforcement is steady. A June–July 2026 crackdown led to 1,666 arrests, mostly over deals arranged through messaging apps. Massage parlours were the biggest offline category.

Korean nightlife runs on licence types set by the Enforcement Decree of the Food Sanitation Act. An 'entertainment bar' (yuheung jujeom, the licence room salons use) may employ hostesses and let guests sing or dance. A 'karaoke bar' (danran jujeom) lets guests sing, but without hostesses. Both are legal businesses. Paying for sex inside one is not, and police raid venues that sell it. In 2026 they busted a 65-room 'full salon' in Gangnam (Korea JoongAng Daily).

An ordinary noraebang (singing room) is stricter than most visitors expect. Under Article 22 of the Music Industry Promotion Act it may not sell alcohol or supply attendants of any gender.

Massage is the biggest grey area. The Medical Service Act gives the masseur licence only to visually impaired people. That leaves most of Korea's estimated 80,000 massage businesses outside the system, and their operators risk up to three years in prison or a 30 million won fine (Asia Business Daily, 2024).

Korean law applies to visitors exactly as it does to locals, so a foreign customer faces the same penalty under Article 21. For a foreigner, immigration is the bigger issue. Under the Immigration Act, the authorities can deport a foreign national deemed 'highly likely to engage in any conduct disturbing economic or social order or good morals', or one released after a prison sentence (Articles 11 and 46). Anyone deported can then be refused entry for five years (Article 11).

The age of consent in Korea is 16. Since a 2020 change to the Criminal Act, an adult aged 19 or over who has sex with someone aged 13 to 15 is punished under the rape provisions, consent or not (Article 305). With a child under 13, that applies to anyone.

For anything paid, the line is 19. The Act on the Protection of Children and Youth against Sex Offenses treats everyone under 19 as a minor. Buying sex from a minor carries one to ten years in prison or a fine of 20 to 50 million won, and more if the child is under 16 (Articles 2 and 13). The Youth Protection Act also keeps under-19s out of adult venues, which is why bars and clubs check ID.

Korea holds Tier 1, the top grade, in the US State Department's 2026 Trafficking in Persons report. Even so, the report describes foreign women on E-6-2 entertainment visas, many from the Philippines and Thailand, being forced into commercial sex in bars. That includes 'foreigners only' bars near ports and US military bases. Signs worth noticing: someone who doesn't hold their own passport, can't leave, or seems afraid of a manager. Call the police on 112, or the government's trafficking counselling line on 1600-8248 (Ministry of Gender Equality and Family). The 1366 women's emergency line runs 24 hours a day and covers prostitution-related abuse.
