A year after Nihon Hidankyo was awarded the Nobel Peace Prize, the Japanese group’s 93-year-old co-chair continues working hard to move public opinion toward the abolition of nuclear weapons.

“We’ve seen no progress toward the abolition of nuclear weapons” since the group, formally called as the Japan Confederation of A- and H-Bomb Sufferers Organizations, won the prize, Terumi Tanaka said in a recent interview.

“We have to change people’s will,” said Tanaka, who has been traveling around Japan giving lectures about eliminating nuclear weapons despite his advanced age.
