Nagasaki is the capital and the largest city of Nagasaki Prefecture on the island of Kyushu in Japan. It became a centre of Portuguese and other European influence in the 16th through 19th centuries, and the Churches and Christian Sites in Nagasaki have been proposed for inscription on the UNESCO World Heritage List. Part of Nagasaki was home to a major Imperial Japanese Navy base during the First Sino-Japanese War and Russo-Japanese War. Its name means "long cape". During World War II, the American atomic bombings of Hiroshima and Nagasaki made Nagasaki the second and, to date, last city in the world to experience a nuclear attack. As of 1 January 2009, the city has an estimated population of 446,007 and a population density of 1,100 persons per km². The total area is 406.35 km².
