Nihon Hidankyo, which won this year's Nobel Peace Prize, says it will call on the Japanese government to join the Treaty on the Prohibition of Nuclear Weapons.

The three co-chairpersons of the Japanese group of atomic bomb survivors met with Norwegian Prime Minister Jonas Gahr Stoere on Wednesday, the day after the award ceremony in Norway. The three are Tanaka Terumi, Tanaka Shigemitsu and Mimaki Toshiyuki.

Stoere said he was moved by the message in Tanaka Terumi's speech at the ceremony. He said Tanaka vividly recounted the horrors of destruction caused by an atomic bomb.

After the meeting, the Norwegian prime minister held a joint news conference with Tanaka.

Stoere said one achievement of humanity is that no nuclear weapons have been used since 1945. He also said pressure should be put on nuclear powers to work on disarmament again.

Tanaka said the prime minister has a strong desire to abolish nuclear weapons, and he is very happy that the Norwegian government wants to stick to that.

Tanaka also said the Japanese government is not fully listening to Hidankyo's voice. He noted that in light of the Japan-US alliance, Tokyo continues to take the stance of not signing or ratifying the Treaty on the Prohibition of Nuclear Weapons.

Tanaka said Japan, which calls itself a nuclear war victim, needs to take the initiative. He went on to say that after returning to Japan, they want to ask the government to join the pact and exercise leadership until nuclear weapons are eliminated, as soon as possible.
