Official replicas of the medal and the diploma of the 2017 Nobel Peace Prize have been put on display at the Hiroshima Peace Memorial Museum in the atomic-bombed city.
The International Campaign to Abolish Nuclear Weapons, or ICAN, won last year's prize. Before the display's opening on Sunday, ICAN official Tim Wright said it is an honor to have the replicas shown in Hiroshima.
He said he believes efforts made by atomic bomb survivors, known as hibakusha, were instrumental in ICAN being awarded the Peace Prize.
Visitors to the exhibit included families with children. They saw the likeness of the medal bearing the profile of Alfred Nobel, the founder of the prize.
The international NGO was commended for its contribution to the adoption of the Treaty on the Prohibition of Nuclear Weapons at the United Nations in July last year.
The treaty will go into effect after being ratified by 50 signatories. Twelve countries have so far done so. Japan is the only country to have suffered atomic-bombings, but has not joined it.
A visitor from Kobe who went to the memorial museum with his child said he wants to see progress in efforts to abolish nuclear weapons.
The exhibit runs through August 6th, and will move to Nagasaki City on the 8th.
