I Saw It: The Atomic Bombing of Hiroshima: A Survivor's True Story, titled Ore wa Mita (おれは見た) in Japanese, is a one-shot manga by Keiji Nakazawa that first appeared in 1972 as a 48-page feature in the magazine Monthly Shōnen Jump.

In 1945, elementary student Keiji Nakazawa's mother wakes him up during an air raid and they rush into a wet shelter.

His father also did traditional Japanese paintings and his brother Yasuto welded the hulls of ships at the Kure Shipyard.

The schoolyard wall had blocked most of the flames from the blast, though his cheek was impaled by a nail in a wooden board.

Keiji returned to his home to learn that his mother, who had recently given birth to a baby girl, was waiting for him by the tracks on Yamaguchi Street.

The baby girl his mother gave birth to on the day of the bombing died and was cremated on the beach.

Wanting to improve his drawing skills, Keiji began working as a sign painter for a former war veteran.

When they cremated her body, the radiation remaining in her from the bomb caused her bones to disintegrate, leaving only white dust instead of the usual ashes.
