Chinatown

The Nagasaki Chinatown is not very big, but that works in its advantage you can find a lot of things around (mostly Pubs, restaurants ...) of China that can not be found anywhere else in the area. It is also a prelude to the Temple of Confucius, and I recommend walking from Chinatown, because on the way you can see one of the most lovely parts of the city. Not the most spectacular Chinatown, but I think it is an essential place to visit if you're in Nagasaki.
