‘True horror’: Japan’s Hiroshima atomic bomb survivor campaigns for a nuclear-free world

“What I feel the most about these days is human stupidity,” says 93-year-old Bun Hashizume, from her home in the Japanese temple city of Kamakura.

“I was a victim of the first atomic bomb in human history and I have advocated throughout my life for the abolition of nuclear weapons, but the world leaders still do not understand their true horror.

“Even my poems cannot describe it.”

A US atomic bomb named “Little Boy” was dropped from a B-29 aircraft and exploded at low altitude over the city of Hiroshima. With a blast force equal to 16 kilotons of TNT, it destroyed most buildings and caused mass death and injury.

Then aged 14, Hashizume was a war-mobilised school student working in the four-storey reinforced-concrete Savings Bureau building about 1.5km from the hypocentre of the blast.

Looking back, she recalls a third-floor window being filled “with a sudden flash of light that was so bright I thought the sun had fallen at my feet. A thousand rainbows all at once seemed to explode before my eyes”. And how, after being briefly unconscious and bleeding heavily from a head wound, she staggered downstairs among other workers looking “like a parade of ghosts with wildly dishevelled hair and sooty bodies”.

Once outside the building, it was a regular employee, Tomoyanagi, who “half-carried” her to a nearby Red Cross Hospital, where more shocking scenes and high drama followed.

Hashizume is today the author of The Day the Sun Fell – Memoirs of a Survivor of the Atomic Bomb – translated by Susan Bouterey – which closely details her and her family’s horrific experiences and also explains her present-day opposition to “dangerous” nuclear power plants, which she emphasises during this Australian writer’s long-distance interview with her,
