Chinatown is an urban region inhabited by Chinese people in a non-Chinese society. The oldest Chinatown in the world is called Nankinmachi in Nagasaki, Japan, and is nearly 300 years old. Chinatowns first appeared in the major cities of North America in the 19th Century. Around the same time Chinese sailors who settled in the port cities of Europe started to establish Chinatowns there. Some Chinatowns are relatively new. The Chinatown in Las Vegas was formed in the 1990's.
In the past, Chinatowns were seen as sleazy area where white people would go to spend time in opium dens and escape the pressures of non-Chinese society. By the 1960's they lost this image and today have become fashionable and popular cultural, shopping and business centres. During the 1990's, many Chinatowns experienced renewal and became popular tourist attractions.
Although still referred to as "Chinatown", most Chinatowns today are inhabited by a wide variety of people of Asian descent, such as Vietnamese, Japanese, Koreans and Thais.
