Age of consent across Asia
Statutory age of consent for each of the 11 countries this site covers, with recent changes flagged. Important: in every country here, commercial sex with anyone under 18 is prosecuted as a separate and significantly heavier offence (trafficking, child-sex-exploitation statutes) regardless of the underlying age-of-consent threshold for non-commercial sex.
Critical point for adult travellers
The criminal age of consent (column below) governs non-commercial sex. Adult-industry / commercial-sex activity with anyone under 18 is a separate and much heavier offence in every country covered here— including in countries where the underlying age of consent is 15 or 16. Apparent-age mistakes are not a defence under most regional statutes; document verification is the customer's risk. Penalties range from 10 years (Thailand) to life imprisonment (Singapore extraterritorial, Cambodia 2008 Law).
| Country | Age | Notes |
|---|---|---|
| Thailand | 15 | Penal Code §277 (general) sets 15; §279 raises practical exposure to 18 for any 'indecent act' with a person under 18 even with consent. Anti-Trafficking Act 2008 and Criminal Code §317-§327 cover prostitution-of-minor offences with sentences to life imprisonment. |
| Philippines Recent change | 16 | Raised from 12 to 16 by Republic Act 11648 in March 2022 — one of the most significant recent changes in the region. Anti-Trafficking statutes (RA 9208/10364) treat any commercial sex with a person under 18 as trafficking regardless of consent. Raised from 12 → 16 in March 2022 under RA 11648. |
| Vietnam | 16 | Penal Code 2015 (as amended) Article 145 sets 16. Sexual intercourse with a person 13-16 is criminalised separately from rape; under 13 is automatic rape regardless of consent. |
| Indonesia | 18 | Effectively 18 under the post-2014 Child Protection Law (UU 35/2014) for any sexual activity; pre-2014 the threshold was 15. KUHP 2023 (in force January 2026) Article 411 additionally criminalises extramarital sex regardless of age. |
| Japan Recent change | 16 | Raised from 13 (which had been in place since 1907) to 16 by the June 2023 Penal Code amendment that came into effect on 13 July 2023 — the largest change to Japanese sexual-offences law in over a century. Prefectural ordinances on compensated dating apply strict-liability prosecution against customers regardless of belief about age. Raised from 13 → 16 on 13 July 2023. |
| Cambodia | 15 | Penal Code 2009 Article 239. The 2008 Anti-Trafficking law treats any commercial sex with a person under 18 as trafficking regardless of the underlying age-of-consent threshold; foreign tourists face the most aggressive enforcement on this point in the region after the Philippines. |
| South Korea Recent change | 20 | Raised from 13 to 16 by 2020 Penal Code amendment. The 'Adult-and-Junior' (성인보호와 미성년자성보호) framework however operates 20 as the practical age for adult-industry venue entry (mirroring Korea's drinking age). The 2004 Act on Arranging Sexual Traffic prosecutes any commercial sex with anyone under 19 as a child-sex offence. Raised from 13 → 16 in 2020 for the criminal age of consent. |
| Taiwan | 16 | Criminal Code Article 227. The Children and Youth Sexual Exploitation Prevention Act covers commercial sex with anyone under 18 with separate elevated penalties. |
| Singapore | 16 | Penal Code §376A. The Children and Young Persons Act and the 2007 extraterritorial provision criminalise commercial sex with anyone under 18 globally, prosecuted against Singaporean nationals abroad as well as at home. |
| Malaysia | 16 | Penal Code §375A. Syariah Criminal Offences Acts add a separate framework for Muslim defendants (Khalwat / Zina) that operates on different definitions. The Sexual Offences Against Children Act 2017 covers any sexual activity with a person under 18. |
| Hong Kong | 16 | Crimes Ordinance Cap. 200 §124. The 2018 amendments to the Prevention of Child Pornography Ordinance and the 2021 voyeurism amendments (§159AAA) significantly tightened the surrounding framework. Commercial sex with a person under 18 is prosecuted under §139 (procurement) as well as §124. |
The three-tier framework you actually need to think in
Reading the table above as a single number per country is misleading. For adult-travel risk, three thresholds matter, in this order:
- Criminal age of consent (the table). Governs non-commercial sex with locals. Mostly 16 across the region, with Korea at 20 in practice for adult-industry venues, Thailand and Cambodia at 15.
- Adult-industry venue age. Typically 18 (Japan, Singapore, Thailand entertainment-licensing) or 20 (Korea). A venue that employs a worker under this threshold is itself in violation of licensing law regardless of consent.
- Commercial-sex / trafficking threshold. Always 18. Sex-for-money with anyone under 18, anywhere in the region, is prosecuted under trafficking or child-exploitation statutes with significantly heavier penalties than the underlying offence. Apparent-age mistakes are not a defence in most jurisdictions. This is the threshold that matters most for tourist risk.
Recent changes worth knowing
- Japan raised from 13 to 16 on 13 July 2023 — its first sexual-offences-law overhaul since 1907.
- Philippines raised from 12 to 16 in March 2022 under RA 11648 — the lowest in the region until that change.
- Korea raised from 13 to 16 in 2020 for the criminal threshold (the practical adult-industry threshold remains 20).
- Indonesia effectively at 18 since UU 35/2014; KUHP 2026 added extramarital-sex criminalisation regardless of age.
