East Asia China

Officially, prostitution is illegal in mainland China, but in practice is widespread. Section 5: Discrimination, Societal Abuse, and Trafficking in Persons.

Shortly after taking power in 1949, the Chinese Communist Party embarked upon a series of campaigns that purportedly eradicated prostitution from mainland China by the early 1960s. Since the loosening of government controls over society in the early 1980s, prostitution in mainland China not only has become more visible, but can now be found throughout both urban and rural areas. In spite of government efforts, prostitution has now developed to the extent that it comprises an industry, one that involves a great number of people and produces a considerable economic output. Prostitution has also become associated with a number of problems, including organized crime, government corruption and sexually transmitted diseases. For example, a Communist Party official who was a top provincial campaigner against corruption was removed from his post after he was caught in a hotel room with a prostitute."Chinese anti-corruption official sacked for Russian tryst ".

Hong Kong

Prostitution in Hong Kong is itself legal, but organised prostitution is illegal, as there are laws against keeping a vice establishment, causing or procuring another to be a prostitute, living on the prostitution of others, or public solicitation.United States Department of State, "2008 Human Rights Report: China (includes Tibet, Hong Kong, and Macau)", Bureau of Democracy, Human Rights, and Labor, 2008 Country Reports on Human Rights Practices, 25 February 2009

The most visible public venues for sex workers in Hong Kong, especially for tourists, are massage parlours and the so-called "Japanese style night clubs". However, most of the commercial sex worker industry consists of women working in small, usually one-room apartments, usually referred to as "one-woman brothels", the equivalent of the "walk-up brothel" in the United Kingdom. They advertise for clients through the Internet and local classifieds. Most popular mainstream newspapers will carry such classifieds with brothel guides as an insert within racing form guides. Yellow neon advertising boxes were used to advertise sexual services to such an extent that "yellow" (黃) became synonymous with prostitution.

Macau

Prostitution is legal in Macau unlike in mainland China, because the city is a special administrative region of the country. However, operating a brothel and procuring are both illegal in Macau, with the latter punishable by a maximum jail sentence of 8 years. The city has a large sex trade despite there being no official red-light district. The trade is said to be controlled by Chinese organized crime groups, which has occasionally led to violent clashes. Street prostitution takes place in Macau and prostitutes also work in low-rent buildings, massage parlours and illegal brothels, and the casinos, nightclubs, saunas and some of the larger hotels. Most hotels, however, have suspected prostitutes removed from the premises. Many of the city's sidewalks and underpasses are littered with prostitutes' calling cards.

Japan

Prostitution is illegal in Japan; however, as the definition of prostitution is "intercourse with an unspecified person in exchange for payment", the sale of other sexual services is legal and widespread.

Prostitution has existed throughout the country's history. While the Anti-Prostitution Law of 1956 states that "No person may either do prostitution or become the customer of it," loopholes, liberal interpretations and loose enforcement of the law have allowed the sex industry to prosper and earn an estimated 2.3 trillion yen ($24 billion) a year.

In Japan, the is not synonymous with prostitution. Since Japanese law defines prostitution as "intercourse with an unspecified person in exchange for payment," most fūzoku offer only non-coital services, such as conversation, dancing, or bathing, to remain legal."Law bends over backward to allow 'fuzoku'", Japan Times, 27 May 2008. Nevertheless, polls by MiW and the National Women's Education Center of Japan have found that between 20% and 40% of Japanese men have paid for sex.

There are 20 brothel-villages in the country. The largest is Daulatdia which has about 1,300 sex workers, it is one of the largest brothels in the world.

Unwed mothers, orphans, and others outside the normal family support system are the most vulnerable to human trafficking. Government corruption greatly facilitates the process of trafficking.
