Today, I'll introduce Nagasaki.
Nagasaki is famous for "dezima". In Edo age, the government at that time(=Edo bakuhu) closed the door to foreigners. In other words, they closed own country to outsider. Japan had no trade relations with foreign countries. People at that time had no way to get information or articles of outsider. But "dezima" was the only place where government permit to carry on commerce. "dezima" is historically very important place. Now, that is a popular tourist destination.
By the way, favorite food in Nagasaki is sponge cake; now traditional to Japan, and containing many local ingredients, but originally imitated from that of Castella in the 16th century.
