Former Hiroshima Mayor Tadatoshi Akiba has received a German medal given to people who have made significant contributions to world peace.
Akiba was handed the Otto Hahn Peace Medal by the mayor of Berlin at a ceremony in the German capital on Tuesday. He is the first Japanese to receive the award.
Akiba was the mayor of Hiroshima from 1999 to 2011.
The city was the site of the world's first atomic bombing in 1945.
Akiba campaigned for the abolition of nuclear weapons by 2020 as the president of Mayors for Peace, an organization of more than 5,500 cities.
Akiba said in his speech that atomic bomb survivors are continuing their efforts to realize a world free of nuclear weapons while suffering from the after-effects of the bombing.
After the ceremony, Akiba called on the leaders of nuclear powers and countries that plan to possess such weapons to visit Hiroshima and think about a new era.
The peace medal was created in 1988 by the United Nations Association of Germany. It's named after the German nuclear chemist and Nobel laureate Otto Hahn, who also worked as a peace activist.
