Hiroshima: In 1945, the American military detonated an atomic bomb over this Japanese city, killing thousands of people instantly. Today, visitors can pay their respects at Hiroshima's Peace Memorial Park. The cenotaph, pictured, was aligned to frame the Peace Flame and the A-Bomb Dome.

Symbols of peace: Paper cranes symbolizing peace adorn a memorial inside the Hiroshima Peace Memorial Park.

Genbaku Dome: A man relaxes alongside the river on a bench overlooking the half-exploded Genbaku Dome. To this day, it's a stark reminder to all who live and visit of the devastating impact of war.

Children's Peace Monument: A woman takes a photograph of the Children's Peace Monument in Hiroshima's Peace Memorial Park.

Hiroshima pride: A new exhibition in Hiroshima Gate Park highlights how quickly businesses joined recovery efforts. For instance, the bomb wrecked power distribution facilities within a two kilometer radius of its hypocenter. Employees from the Chugoku Electric Power Company immediately worked to restore power for residents.

Mazda's tricycle trucks: in December 1945, automotive manufacturer Mazda resumed production of its tricycle trucks and made it a priority to get them to Hiroshima to help people transport essential items needed for daily life.

Aiding the recovery: The three-wheeled trucks became a familiar sight around Hiroshima city in the post-war months.

Back on track: The Hiroshima Electric Railway lost 185 employees in the atomic bombing and 108 of its 123 streetcars were burned or damaged. However, the railway company managed to resume operations on some of its lines just three days after the bombing.

Hiroshima survivor: Okihiro Terao holds up a stained-glass crane that he made to symbolize peace. He said he sent one decorated in the colors of the Ukrainian flag to the Ukrainian Embassy in Tokyo.

Remembering the past: Terao points to a photograph showing Hiroshima before the atomic bombing and the house where he spent the first four years of his life. He said he grew up seeing the roof of what is now the Genbaku Dome every day from his childhood home.

Painful reminders: The force of the atomic blast threw Terao -- then aged four -- off his feet and shattered windows. Glass shards peppered Terao, leaving scars all over his body that are visible to this day.

Hiroshima tourists: Visitors Sofia Trommlerova and Dušan Brejka from Slovakia say the Genbaku Dome makes them reflect on the tragedy and hope of war.
