Atomic Bomb Hypocenter Park

Atomic Bomb Hypocenter Park marks the precise point roughly 500 meters above which the plutonium bomb detonated on August 9, 1945, identified by a simple black stone monolith at the center of a sunken circular plaza. The surrounding grounds display a preserved cross-section of the original ground layer showing scorched soil, and a section of the original Urakami Cathedral's stone wall, relocated here as a memorial to the destruction that leveled the surrounding neighborhood in seconds. A memorial mound nearby holds unidentified remains recovered after the bombing, and low walls around the plaza list statistics on the blast's temperature, casualties, and radius of destruction. The park is small and can be walked through fully in twenty to thirty minutes, most of it spent reading the memorial plaques and standing at the hypocenter monolith itself. It connects directly by footpath to both Peace Park and the Atomic Bomb Museum, and the three sites are almost always visited together as a single memorial route through Urakami. The park is at its most solemn and crowded on the August 9 anniversary, when a moment of silence is observed citywide at 11:02 AM, the exact time of the blast; on other days it remains a quiet, contemplative space with few visitors at any given time.
