Nagasaki Shinchi Chinatown

Nagasaki Shinchi Chinatown (Japanese: 長崎新地中華街, Simplified Chinese: 长崎新地中华街) is an area located in Nagasaki, Nagasaki, Japan. Today this area is a shopping strip covering many blocks. 
Most of the Chinese members of Nagasaki Chinatown are of Fuzhounese descent. Nagasaki and Fuzhou established ties as sister cities in 1980 to recognize the historical connections between the two cities and Fuzhounese immigrant community.
History.
The town was home for many Chinese sailors and traders who trade goods with the Japanese from the 15th to 19th centuries. The Chinese traders came to Nagasaki because it was the only "open port" to visit Japan at this time. 
The Tokugawa government allowed only Nagasaki to stay open to the rest of the world, but closed off the rest of Japan to prevent Western influences and the spread of Christianity. 
Strict rules were placed on these Chinese traders, forcing them to stay in this Chinatown, and preventing them from going outside the town at night. Any one found outside of the town at certain times were arrested by the local guard.
