Nagasaki Travel Guide: Sights, Food & When to Go

Nagasaki (長崎県) is a prefecture in the Kyushu region of Japan. Its capital is Nagasaki; it has a population of about 1.3 million and an area of 4,131 km². Nagasaki was one of the few Japanese ports open to foreign trade during the Edo period.

Nagasaki occupies a peninsula and archipelago on Kyushu's west coast and holds a uniquely international history as the only Japanese port open to European and Chinese trade during the country's centuries of self-imposed isolation, centered on the small artificial island of Dejima. The city was devastated by the second atomic bomb attack on August 9, 1945, and the Peace Park and Atomic Bomb Museum preserve that history alongside a city that rebuilt into one of Japan's most distinctive, hilly, harbor-front cityscapes. Glover Garden preserves the former homes of 19th-century foreign merchants, and Nagasaki's own version of Chinatown reflects centuries of mixed heritage, visible too in local dishes like champon and castella cake introduced by Portuguese traders. Hundreds of scattered islands, including the abandoned mining island of Hashima, add to the prefecture's unusually varied geography.
