Nagasaki History & Heritage Guide 2026

Explore the rich history, historical sites, and museums of Nagasaki.

Nagasaki has 6+ historical sites covered in this guide, led by Atomic Bomb Museum, Dejima Museum (within Dejima) and 26 Martyrs Museum. Each entry below includes the practical details — what it costs, when to go, and how to plan around it.

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.
