From the Atomic Bomb Dome, cross over into Peace Memorial Park , which is dotted with memorials, including the cenotaph (原爆死没者慰霊碑), which contains the names of all the known victims of the bomb. The cenotaph frames the Flame of Peace (平和の灯), which will only be extinguished once the last nuclear weapon on earth has been destroyed, and the Atomic Bomb Dome across the river.

Just north of the road through the park is the Children's Peace Monument (原爆の子の像), inspired by Sadako Sasaki. When Sadako developed leukaemia at 11 years of age in 1955, she decided to fold 1000 paper cranes. In Japan, the crane is the symbol of longevity and happiness, and she was convinced that if she achieved that target she would recover. She died before reaching her goal, but her classmates folded the rest. The story inspired a nationwide spate of paper-crane folding that continues to this day.

Nearby is the Korean Atomic Bomb Memorial (韓国人原爆犠牲者慰霊碑). Many Koreans were shipped over to work as slave labourers during WWII, and Koreans accounted for more than one in 10 of those killed by the atomic bomb.
