Delegation members of Nihon Hidankyo, a Japanese organization of survivors of the 1945 atomic bombings in Hiroshima and Nagasaki, have left for Norway to attend the award ceremony for this year's Nobel Peace Prize.

About 30 delegates, including atomic-bombing survivors, or hibakusha, headed to Tokyo's Haneda Airport on Sunday morning. The organization's three co-chairs, Tanaka Terumi, Tanaka Shigemitsu, and Mimaki Toshiyuki, were among them.

Tanaka Terumi, who experienced atomic bombing in Nagasaki when he was 13 years old, is to deliver a speech at the ceremony in Oslo on Tuesday.

He plans to convey to the world the consequences of the atomic bombing and the inhumane nature of nuclear weapons based on his own experiences, which included losing five relatives.

Tanaka said support from around the world will be needed to continue the campaign that has been carried out by hibakusha.

He expressed his hope to make his organization more widely known around the world.

The delegates are scheduled to stay in Norway until Thursday.

The atomic-bomb survivors plan to speak to reporters from various countries and visit local schools to talk about their experiences, in a bid to appeal to the world for abolition of nuclear weapons amid growing nuclear threats.
