TOKYO — Nagasaki's mayor criticized Japan's government on Friday for failing to back an international nuclear disarmament effort as the country marked the 68th anniversary of the atomic bombing of his city.
Mayor Tomihisa Taue said Japan's inaction "betrayed expectations of the global community."
Japan refused in April to sign an unconditional pledge by nearly 80 countries to never use nuclear weapons.
The document, prepared by a U.N. committee, is largely symbolic because none of the signatories possesses nuclear weapons. Countries with nuclear arsenals that have not signed it include the United States, Russia, India and Pakistan.
Japan does not have nuclear weapons and has pledged not to produce any, although some hawkish members of the ruling party say the country should consider a nuclear option.
Taue said that as the world's only victim of atomic bombings, Japan's refusal to join the initiative contradicts its non-nuclear pledge.
"I call on the government of Japan to return to the origin of our pledge as an atomic-bombed country," he said at the peace park near the epicenter of the 1945 blast.
Tokyo apparently refused to sign the document because of its security arrangement with the United States, which could allow the U.S. an option to deploy nuclear weapons from Japan to counter the threat of North Korea.
