For more than 70 years, Hiroshima resident Tokuo Shimizu kept the gruesome memories of the hellish scenes he saw at ground zero the day after the atomic bombing to himself.
But at the age of 86, Shimizu has decided to share his A-bomb memories with younger generations to pass on the message that human beings should never wage war again.
Shimizu was a second-year student at the Hiroshima Municipal Shipbuilding Engineering School (now Hiroshima Municipal Commercial High School) when the atomic bomb exploded over the city on Aug. 6, 1945.
