A co-chair of Nihon Hidankyo has expressed his resolve to continue to call for the abolition of nuclear weapons in 2025, the 80th year after the atomic-bombings of Hiroshima and Nagasaki.

The group represents survivors of the 1945 bombings. It was awarded the Nobel Peace Prize last year.

Hidankyo Co-Chairperson Mimaki Toshiyuki visited the Peace Memorial Park in Hiroshima on Tuesday with group members from the prefecture to lay flowers at the cenotaph for the victims.

He said although survivors are getting old, they won't give up their efforts to call for the abolition of nuclear weapons. He said the mistake of using the weapons must not be repeated.

He later told reporters he believes remarks made by fellow Co-Chairperson Tanaka Terumi at the Nobel Peace Prize award ceremony last month reached across the world.

He said the world is becoming unstable, with the United States set to have a new president and some countries engaged in war. But he feels as if his predecessors are encouraging Hidankyo to continue its efforts.

Mimaki and other Hidankyo members are scheduled to meet Prime Minister Ishiba Shigeru on Wednesday.

He said they will urge the Japanese government to take part in a meeting of States Parties to the UN Treaty on the Prohibition of Nuclear Weapons in March, at least as an observer.
