Nagasaki Memorial Day

Nagasaki Memorial Day is observed every year on August 9 to remember the atomic bombing of Nagasaki in 1945. Just three days after Hiroshima was bombed, the city of Nagasaki faced a similar tragedy. At 11:02 AM, an atomic bomb exploded over the city, killing tens of thousands of people instantly and causing lasting damage for generations. This bombing played a major role in ending World War II, as Japan surrendered shortly after.

The day stands as a reminder of the horrors of nuclear weapons and the suffering of innocent civilians. Over the years, Nagasaki Memorial Day has become a symbol of Japan's commitment to peace and nuclear disarmament. Survivors, known as hibakusha, have shared their painful memories to educate younger generations. The city has rebuilt itself while keeping the memory of that day alive through museums, monuments, and annual ceremonies that reflect on the past and look toward a peaceful future.
