Delegates of Nihon Hidankyo, the winner of this year's Nobel Peace Prize, have entered their hope of a world without nuclear weapons into a guest book in Oslo, Norway.

Tanaka Terumi, Mimaki Toshiyuki and Tanaka Shigemitsu, are the three co-chairs of the Japanese organization made up of survivors of the 1945 atomic bombings of Hiroshima and Nagasaki.

On Monday, they visited the Norwegian Nobel Institute ahead of the award ceremony scheduled for next day.

Tanaka Terumi added his signature to the guest book, along with his hope that people will create a world without nuclear weapons and without war. Mimaki Toshiyuki and Tanaka Shigemitsu also signed the page.

In a news conference held before the signings, Tanaka Terumi said it is regrettable and sad that we live in an era in which nuclear weapons and their use are spoken of lightly.

He said they hope to make utmost efforts to tell younger generations that nuclear weapons should never be allowed to coexist with people.
