Nihon Hidankyo, a Japanese organization of hibakusha, or atomic bomb survivors, says it will send 31 people to the award ceremony when it receives this year's Nobel Peace Prize.

The group, also known as the Japan Confederation of A- and H-Bomb Sufferers Organizations, has worked for the abolition of nuclear weapons from the perspective of hibakusha.

The ceremony will be held in Norway's capital Oslo on December 10.

Nihon Hidankyo announced on Friday that the 31 people will include the group's three co-chairpersons, as well as other hibakusha and children of such people.

The group said one A-bomb survivor living in Brazil and another living in South Korea will also attend, along with a child of a survivor.

The attendees will also include UN Under-Secretary-General Nakamitsu Izumi and Kawasaki Akira, an International Steering Group member of the International Campaign to Abolish Nuclear Weapons, or ICAN, which won the prize in 2017.

The Japanese group said the three co-chairpersons will be on stage at the ceremony and that one of them, Tanaka Terumi, will deliver a speech. The 92-year-old experienced the 1945 bombing in Nagasaki.

Participants will leave Japan on December 8 and stay in Norway until December 12 to attend related events and speak about their experiences to local students.
