Nagasaki is a port city on Japan's Kyushu island with a uniquely layered history — centuries of trade with China, Portugal, and the Netherlands left behind temples, cathedrals, and Western-style mansions, while August 9, 1945 marked it as the second city struck by an atomic bomb. Today Nagasaki blends solemn peace memorials with lively Chinatown streets, hillside tram rides, and some of Japan's most distinctive cuisine.
