A co-chair of Nihon Hidankyo has visited Hiroshima's Peace Memorial Park to report the group's win of this year's Nobel Peace Prize to victims of the 1945 atomic bombing of the city.

The group represents survivors of the atomic bombings of Hiroshima and Nagasaki. It was awarded the Nobel Peace Prize last week in Norway.

On Wednesday, the group's co-chair Mimaki Toshiyuki, board member Tanaka Satoshi, and local high school student Kai Natsuki, who attended the award ceremony as a peace ambassador, visited the Cenotaph for the Victims of the Atomic Bomb at the memorial park in Hiroshima.

After laying flowers at the cenotaph, they reported the Nobel Peace Prize win and prayed for the victims.

Mimaki later told reporters that next year marks 80 years since the atomic bombs were dropped, and he hopes winning the award prompts people around the world to think about peace.

Kai's late great-grandparents were exposed to atomic bomb radiation. She said she wants to tell them their thoughts have been passed on to later generations.
