"Open," said Terumi Tanaka, Shigemitsu Tanaka, and Toshiyuki Mimaki, representatives of Nihon Hidankyo, in unison, as they opened the exhibition in the presence of 250 guests. Among those present were diplomats, journalists, and supporters closely following the event. The opening took place the day after they had received the Nobel Peace Prize medal at Oslo City Hall.

"With this exhibition we want to show the devestating humanitarian consequences of the atomic bomb but at the same time show hope - and that a world free of nuclear weapons is possible. The determination and hard work of Nihon Hidnakyo through 70 years is the red thread. We encourage our visitors to listen to the hibakusha, talk about the nuclear threat and act so that nuclear weapons will never be used again," said director Kjersti Fløgstad during the opening.

This year’s Peace Prize photographer, the renowned Magnum photographer Antoine d’Agata, was also present at the opening. D’Agata, who visited Hiroshima and Tokyo in December to document the elderly Hibakusha – survivors of the atomic bombings in 1945 – has captured powerful and emotional images that are now displayed in the exhibition. The photographs provide a unique and intense visual impression of the personal stories of those who survived and vividly show the consequences of the destruction of war.

"It was a beautiful encounter," said d’Agata, sharing his thoughts on photographing the Hibakusha.

A Message to Humanity opens to the public today at 11 AM and will be on display until November 2025.
