Every year on the evening of 6 August, after the morning’s memorial ceremony, Hiroshima marks the anniversary of the atomic bombing with toro nagashi, the floating of paper lanterns. Thousands of lanterns, each carrying a handwritten message of peace or remembrance for the dead, are set on the Motoyasu River and drift slowly past the illuminated A-Bomb Dome as darkness falls. It draws people from all over the world and locals whose families were lost that day, and the atmosphere is quiet and profoundly moving rather than festive. Visitors can buy and write their own lantern to float.

Tips
Book accommodation months ahead, as 6 August fills the city completely. Arrive well before dusk to buy and write a lantern if you want to float one, and treat the evening as the act of mourning it is — keep quiet, be careful and respectful with photographs, and remember many people around you are remembering family members who died that day.
