More than 500 people have gathered at a symposium in Hiroshima to discuss ways to eliminate nuclear weapons and efforts to achieve peace.
The event was held on Saturday at the International Conference Center in Hiroshima's Peace Memorial Park.
Among the speakers was film director Nobuhiko Obayashi, whose latest work has the theme of war and the atomic bombing of Hiroshima in 1945.
The 81-year-old Obayashi survived World War Two near Hiroshima. He said he wants to pass on his experiences of war to future generations. He added he wants to achieve peace by conveying his story through his films.
Another speaker was actress Chizuru Azuma, who has had a chance to take a boat trip with Japanese NGO Peace Boat. The group has been organizing a global voyage with atomic bomb survivors to raise public awareness of the catastrophic consequences of the use of nuclear weapons.
Azuma said it is important to know what happened in the past, think what you can, and act accordingly.
Specialists in a number of fields also took part in a panel discussion. Among them was Haruka Katarao from the Japan International Cooperation Agency. JICA was involved in the adoption of the UN Treaty on the Prohibition of Nuclear Weapons two years ago.
Katarao stressed the need to increase the number of supporters of the treaty to ensure its universal operation.
