An urban park in Hiroshima built for people to pray for world peace near the epicenter of the a-bomb strike on August 6, 1945. The park contains the World Heritage Site “A-Bomb Dome (Genbaku Dome),” the Cenotaph for the A-bomb Victims, the Peace Memorial Museum, and other facilities that preserve and convey the tragic legacy. If you walk around the park, you will see thousands of orizuru (folded origami cranes) everywhere. Orizuru became a symbol of peace after the death of a girl who was exposed to radiation at the age of two and kept folding cranes in hopes of recovery. Even today, the park receives more than 10 million orizuru (weighing about 10 tons) annually from all over Japan and the world, four of which in 2016 were folded by the then U.S. President Obama – an epoch-making event to be remembered by history.
