Atomic Bomb Museum & Peace Memorial Hall

The museum’s permanent exhibition is structured as a descent. You enter at street level, spiral down past a clock stopped at 11:02, and emerge into the recreated rubble of the Urakami valley — a partial church wall, melted glass bottles, a child’s lunchbox carbonized into a single black brick. The medical and survivor-testimony sections are unsparing. A separate floor covers the broader history of nuclear weapons and the international disarmament movement.

The Nagasaki National Peace Memorial Hall for the Atomic Bomb Victims, designed by Akira Kuryu and opened in 2003, sits next door and is included in any serious visit. It is mostly underground — a long ramp descends to a vast subterranean Hall of Remembrance lined with twelve glass pillars containing the registers of confirmed victims, lit from above through a shallow water basin you can see from outside. There is no signage, no audio, no interpretation; it is purely a space for silence.

Take the museum first, then the Memorial Hall, then the Peace Park outside. Doing it in that order is what the architecture is designed for.

The bomb detonated at 11:02am on August 9, 1945 — a plutonium implosion device called “Fat Man.” The blast, heat rays reaching several thousand degrees, and radiation reduced roughly a third of Nagasaki City to rubble, killing or injuring approximately 150,000 people. The exhibition is structured to make that number visceral rather than statistical: personal effects, photographs, melted roof tiles, a wristwatch stopped at the moment of detonation.

Admission is 200 yen — an almost insultingly small sum for one of the most important museums in Japan. Closest tram stop is Hamaguchi-machi on tram line 1, a five-minute walk uphill. The museum sits on the slope above Hypocenter Park; do the park first, then climb up. The final exhibition section — covering nuclear testing, stockpiling, and failed disarmament efforts — ends with a wall of signatures and letters to world leaders from Nagasaki mayors, a tradition that continues every year. It is an unusual and quietly devastating document of civic persistence.
