Nagasaki Chinatown is regarded as the oldest established Chinatown in Japan dating back to the 17th century. During a time of the Seclusion Policy in Japan, Chinese traders were forbidden to leave their designated residing area, thus giving birth to this area also known as Shinchi Chinatown. The town was filled with Chinese residents from the 15th to 19th century in Japan. Today this town offers a special Chinese atmosphere from buildings to cuisines for travelers to experience. Nagasaki Chinatown is among the three largest Chinatowns in Japan, along with Kobe Chinatown as well as Yokohama Chinatown. In Nagasaki, the chukagai champon is a local favorite dish which consists of noodles, vegetables and pork mixed in a rich chicken or pork broth. The large amount of vegetables in this dish separates it from other noodle cuisines in Japan, making it a specialty dish enjoyed all over Japan.
