United Nations' treaty to prevent the spread of nuclear weapons

On the 81st anniversary of the atomic bombing of Hiroshima, Mayor Kazumi Matsui deplored nuclear weapons, criticizing major powers for waging wars and urging them to reject deterrence as a policy. Prime Minister Sanae Takaichi pledged a 'realistic approach' toward achieving a world without nuclear weapons within the United Nations framework. The commemoration occurred amid speculation regarding Japan’s potential review of its postwar three non-nuclear principles.
