Is Prostitution Legal in Japan?

Japan's Anti-Prostitution Act (Act No. 118 of 1956) says no one may sell sex or be the customer (Article 3), but it attaches no penalty to that rule. It also defines prostitution narrowly: intercourse with an unspecified partner in exchange for payment (Article 2). The penalties land on everything around it. Soliciting in public can bring up to six months in prison or a ¥20,000 fine (Article 5), arranging prostitution up to two years (Article 6), and running a place where people are made to sell sex up to ten years (Article 12).

That balance may shift. After Prime Minister Sanae Takaichi asked for a review in November 2025, a Justice Ministry expert panel reported in September 2026 that clients who solicit, in public or online, should be penalised. It did not recommend widening the definition beyond intercourse (AFP via France 24). Human Rights Watch said on 24 October 2026 that a reform bill is expected (Human Rights Watch).

Most of Japan's nightlife is plain legal business. Hostess and host clubs need a permit from the prefectural public safety commission (Entertainment Business Act, Article 3). Adult shops, the fuzoku trade, are a separate category: soaplands, strip theatres and similar businesses must notify that commission before opening (Articles 2 and 27). Because the Anti-Prostitution Act only covers intercourse, much of this trade sits outside it, in what the US State Department calls a legal but largely unregulated market (2025 Trafficking in Persons report).

The rules tightened in 2025. Since 28 June 2025, host and hostess clubs may not exploit a customer's romantic feelings to push orders or use intimidation to make them pay, adult shops may no longer pay recruiters a referral fee, and the maximum fine for operating without a licence rose to ¥10 million for individuals and ¥300 million for companies (Kanagawa Prefectural Police). Street touting for hostess clubs and adult shops is banned outright (Articles 22 and 28).

Visitors are under the same rules as residents: paying an adult for sex carries no penalty today, though that may change for clients who solicit (AFP via France 24). Immigration law is stricter. Foreigners who have worked in prostitution or a business directly tied to it can be refused entry or deported, unless they were trafficking victims (Immigration Control Act, Articles 5 and 24). A foreigner sentenced to more than a year in prison, without suspension, can also be deported (Article 24).

Japan raised its age of consent from 13 to 16 in 2023 (AP via PBS). Sex with someone under 16 now counts as non-consensual intercourse, with a minimum of five years in prison; the only exception covers 13- to 15-year-olds whose partner is less than five years older (Penal Code, Article 177). Paying anyone under 18 is a separate crime, with up to five years in prison or a ¥3 million fine (Child Prostitution and Pornography Act, Article 4). Licensed clubs and adult shops may not admit customers under 18 or serve alcohol to anyone under 20 (Entertainment Business Act, Articles 22 and 28).

If someone seems to be held against their will, forced to work or underage, call the police on 110 in an emergency. For tips, the National Police Agency's Anonymous Report Dial on 0120-924-839 takes reports of human trafficking, and the police consultation line is #9110. The Immigration Services Agency lists both, along with a foreign-language information centre on 0570-013904.
