Japanese students use VR to recreate the bombing of Hiroshima

Japanese high school students have produced a virtual reality experience that recreates the images and sounds of the Hiroshima nuclear bomb attack

Japanese high school students have produced a virtual reality experience that recreates the images and sounds of the Hiroshima nuclear bomb attack.

The five-minute clip captures the moments immediately before, during and after the United States dropped an atomic bomb on the city 73 years ago, killing 140,000 people.

By transporting users back in time to the moment a city became a wasteland, students and their teachers hope to ensure that something similar never happens again.

"Even without language, once you see the images, you understand," said Mei Okada, one of the students working on the project at a technical school in Fukuyama, a city about 60 miles east of Hiroshima.

"That is without a doubt one of the merits of this virtual reality experience."

The bombing of Hiroshima on August 6, 1945 marked the first time that a nuclear weapon was used against civilians.

Three days later, a second American atomic bomb killed 70,000 people in Nagasaki.

Japan surrendered six days after that, ending the Second World War.

With the use of virtual reality headsets, users can take a ride on the Motoyasu River before the explosion and see the businesses and buildings that once stood.

They can enter the post office and the courtyard of Shima Hospital, where skeletal remains of a building now known as the Atomic Bomb Dome on the banks of the river are found, a testament to what happened.

The students, who belong to the computer skills research club at Fukuyama Technical High School, were born more than half a century after the bombing.

Yuhi Nakagawa, 18, said he initially did not have much interest in what happened when the bombs were dropped; in any case, it was a subject that he had avoided.

WHAT HAPPENED IN THE BOMBAR OF HIROSHIMA AND NAGASAKI?

The first atomic bomb was dropped on the Japanese city of Hiroshima on August 6, 1945 by an American bomber B-29 nicknamed the Enola Gay.

The 9,000-pound bomb of uranium-235 exploded at 1,900 feet (580 meters) above the ground, killing between 60,000 and 80,000 people instantly, some disappearing instantly from the heat of the big explosion.

Others died when the fire ravaged the city and it is believed that some 135,000 people died from radiation sickness.

The explosion crushed more than six square miles (10 square kilometers) of the city, with fires that burned for three days, leaving thousands of survivors burned and homeless.

With large buildings such as hospitals destroyed and more than 90 percent of the city's doctors and nurses killed in the explosion, there was little help available for the injured.

Ten years later, the longer-term effects of the pumps were noted, including an increase in leukemia, a blood cancer not included in the study.

It was said that cancer disproportionately affected children, and that the cases appeared two years after the bomb and reached a maximum between four and six years later, reported The IBT.

The Radiation Effects Research Foundation estimates that 46 percent of deaths from leukemia at the pump sites between 1950 and 2000 were due to radiation from the bombs, with a total of 1,900 cancer deaths related to the atomic bomb.

"When I was creating the buildings before the atomic bomb fell and then I saw many pictures of buildings that had gone away, I really felt how terrifying the atomic bombs can be," he said.

"So in creating this scenario, I felt it was really important to share this with others."

To recreate Hiroshima, the students studied old photographs and postcards and interviewed survivors of the bombing to hear their experiences and get their comments on the images of virtual reality.

"Those who knew the city very well tell us that it's very good, they say it's very nostalgic," said Katsushi Hasegawa, a computer science professor who oversees the club.

"Sometimes they start to remember their memories of that time, and I'm really glad we created this."
