Justice and Peace Issues
BACKGROUNDOn August 6, 1945, at 8:15 a.m. local time, an American B-29 bomber, the Enola Gay dropped “Little Boy” the world’s first uranium-based atomic bomb over the Japanese city of Hiroshima. The explosion immediately killed an estimated 80,000 people; tens of thousands more would later die of radiation exposure. On August 9, a second B-29 dropped another A-bomb on Nagasaki, killing an estimated 40,000 people.Japan’s Emperor Hirohito announced his country’s unconditional surrender in World War II in a radio address on August 15, citing the devastating power of “a new and most cruel bomb.” By the end of 1945, the death toll had risen to somewhere between 90,000 and 166,000, as survivors — known as hibakusha — succumbed to burns, radiation sickness, and injuries. But the legacy of those two bombs — the trauma, the radiation illness, the generational grief — has never fully ended for those who lived through it or for the families.
WHY HIROSHIMA?Hiroshima was chosen as a target partly because it was a major military and industrial hub, and partly because it had not yet been heavily bombed, which would allow American military planners to clearly assess the bomb’s destructive power. The city’s flat terrain and its position along the Ota River delta made it an ideal test case for the new weapon. Within seconds of the detonation, roughly 69 percent of the city’s buildings were destroyed, and a firestorm swept through the ruins. The human suffering was almost incomprehensible — children walking to school, workers arriving at factories, families eating breakfast — all caught in a moment that changed the course of history forever.
PAPER CRANES – SYMBOLISMThe symbol most closely associated with Hiroshima’s peace message is the paper crane — orizuru in Japanese. This tradition stems from the story of Sadako Sasaki, a young girl who was two years old when the bomb fell and who developed leukemia at age twelve as a result of radiation exposure. Inspired by the Japanese legend that folding 1,000 paper cranes (senbazuru) would grant a wish, Sadako began folding cranes during her illness, wishing for peace and recovery. She died in 1955 before completing her goal, but her classmates finished the cranes and buried them with her. Today, millions of paper cranes are sent to Hiroshima each year from around the world, and Sadako’s statue in the Peace Memorial Park is draped in colorful garlands of folded cranes year-round.
HIROSHIMA TODAYCulturally, Hiroshima has become synonymous with resilience and rebirth. The city that was reduced to ash in 1945 is today a thriving metropolis of over 1.1 million people, home to world-class universities, a vibrant arts scene, and the globally recognized Hiroshima Peace Memorial Museum. The very existence of modern Hiroshima is itself a testament to the human capacity to rebuild, to heal, and to hope.
THE GENBAKU DOME (Atomic Bomb Dome), now a UNESCO World Heritage Site was the only structure left standing in the area where the first atomic bomb exploded on August 6, 1945. It is permanently kept in a state of preserved ruin as a reminder of the destructive effects of nuclear warfare. Not only is it a stark and powerful symbol of the most destructive force ever created by humankind; it also expresses the hope for world peace and the ultimate elimination of all nuclear weapons.
MODERN RELEVANCE: WHY 2026 IS A PIVOTAL YEARHiroshima Day 2026 arrives at a moment of heightened global urgency around nuclear weapons. Geopolitical tensions between nuclear-armed states have increased in recent years, with arms control agreements fraying and new weapons systems being developed.The 81st anniversary in 2026 is also significant because it falls at a time when the last generation of hibakusha is passing from the scene. Within the next decade, there will likely be no living survivors of the atomic bombings left to give firsthand testimony. This makes the work of preserving and transmitting their stories — through museums, digital archives, educational programs, and recorded testimonies — more critical than ever.
AN INVITATIONThis August 6 marks 81 years since the United States dropped atomic bombs on Hiroshima and Nagasaki, killing hundreds of thousands of people and leaving a legacy of suffering that endures to this day. Yet the threat of nuclear weapons has not diminished: more than 12,000 nuclear warheads remain in the world’s arsenals. They pose a significant risk to global safety and peace.In response, the Franciscan Peace Center and the Franciscan Sisters of Perpetual Adoration invite you to join their annual Hiroshima Nagasaki Prayer Service, a virtual gathering open to all at 7 p.m. ET on August 6th. This year’s theme, “From Remembrance to Abolition,” calls us to honor the lives lost while renewing our commitment to a nuclear-free world. This prayer will unite people of faith in a period of prayerful reflection and commitment to peace as we strive to create a world free from the threat of nuclear weapons. As we remember the suffering of Hiroshima and Nagasaki, we pray that world leaders will commit to ending the manufacturing of these weapons of mass destruction and to alleviating the damage already caused by the arms race.If you are unable to attend the live event, you are invited to register, and you will receive a recording afterwards.
