The number of victims of the 1945 atomic bombing of the Japanese city of Hiroshima has climbed up a notch to 557,478 — 15,000 more than the previously recorded figure, according to a new report.

The total number of the explosion-affected people or “hibakusha” from the Second World War atomic bombing by the US is more than 15,000 people recorded in the previous file, according to research by the city government.

This is based on a fresh review of 120,000 documents which was undertaken by computer for the first time.

Of the latest figure, 384,743 hibakusha were confirmed to have been in the city or nearby towns and villages when the atomic bomb was dropped in 1945, up by around 12,000 from the previous survey.

The remainder includes people who later entered areas near ground zero and those who lacked sufficient information about their whereabouts.

The study will most likely be the last one because it is unlikely that any new documents will be discovered, an official suggested.PTI
