The Honest Starting Point
Hiroshima is worth bringing children to. The question is not whether, but how much of the museum to show them, and that decision deserves more thought than a guidebook line.
The Peace Memorial Park itself is fine at any age. It is a large, open, green riverside space with monuments in it. Children run there. The A-Bomb Dome — the one building left standing as it was — is a ruin across the water and reads as a ruin.
The museum is a different matter. The main building's exhibits are deliberately unflinching: personal effects, photographs of injuries, and accounts of individual deaths including children's. It is designed to be difficult, and it succeeds. Many parents find that a child under about ten is either upset by it or does not engage with it at all, and neither outcome serves anybody.
A common approach that works: the East Building first, which covers the historical and political context with far less graphic material, and then a parental decision about the main building based on how the child is doing.
There is no correct age. Children differ enormously, and you know yours. What is worth avoiding is walking in unprepared and discovering the problem in the middle of a crowded exhibition hall.
A guide helps here more than most places, because they can pace the visit and answer questions honestly at a level the child can take. Our Peace Memorial Park group walk covers the outdoor ground in two hours.
