Nagasaki Atomic Bomb Museum

On August 9, 1945, at 11:02 a.m., an atomic bomb exploded over Nagasaki, instantly destroying much of the city and killing tens of thousands of people. The Nagasaki Atomic Bomb Museum serves as a solemn memorial to that event, preserving the memories of survivors, educating visitors about the devastating impact of nuclear weapons and advocating for lasting world peace. Through powerful exhibits and firsthand testimonies, the museum invites visitors to confront one of history’s darkest moments while reflecting on what it means for the future. It’s a deeply moving experience and is essential to understanding Nagasaki’s identity and postwar recovery.

Long before the atomic bombing, Nagasaki was a thriving port city known for its international exchange, cultural diversity, and vibrant daily life. During Japan’s period of national isolation (sakoku), it remained one of the few gateways to the outside world. This unique status allowed Nagasaki to absorb Japanese, Chinese, Dutch, and Portuguese influences, which shaped its architecture, cuisine, and cultural spirit.

The museum vividly portrays the prewar city: quiet neighborhoods, bustling markets and children walking to school. It captures a moment frozen in time, just before everything changed and stands in stark contrast to the devastation that followed the detonation of the “Fat Man” atomic bomb.

Exhibits guide visitors through the moment of impact and its aftermath with powerful, emotionally charged displays. Charred buildings, melted glass, scorched clothing and a clock stopped at 11:02 a.m. the exact time of the explosion—bring the horror into sharp focus. Survivor testimonies, archival photographs and a reconstructed wall from the destroyed Urakami Cathedral illustrate the profound human cost of war.

Yet Nagasaki’s story is not only one of loss. It is also a story of resilience. The city rebuilt itself physically and spiritually and emerged as a global advocate for peace and nuclear disarmament.

The museum’s mission goes beyond documenting destruction. It is deeply committed to education and advocacy. In the “World Free of Nuclear Weapons” section, visitors can explore global disarmament efforts and discover how Nagasaki has become a powerful symbol of peace. Videos, interactive exhibits, and multilingual guides make the history accessible to people of all ages and backgrounds, helping them understand the complexities of nuclear conflict and the urgency of prevention.

Before you leave, visit the adjacent Nagasaki National Peace Memorial Hall for the Atomic Bomb Victims and nearby Hypocenter Park, where a black monolith marks the bomb’s epicenter. Just north of there is Nagasaki Peace Park, another space dedicated to remembrance. Together, these memorials offer a place for mourning, reflection and renewed hope.
