Japan on Sunday commemorated the 78th anniversary of the atomic bombing of Hiroshima in the final phase of World War II.
Considering the growing nuclear threat worldwide, the mayor of Hiroshima Kazumi Matsui called for the abolition of nuclear weapons and described the nuclear deterrence policy of G7 as "folly."
"They must immediately take concrete steps to move us from the dangerous present to our ideal world," he said as a peace bell rang on Sunday at 8:15 a.m. — exactly when on August 6, 1945, US bomber Enola Gay set off the world's first atomic bomb dropped on a population center.

"Leaders around the world must confront the reality that nuclear threats now being voiced by certain policymakers reveal the folly of nuclear deterrence theory," Hiroshima Mayor Kazumi Matsui said at the ceremony which was also attended by Kishida.
At the memorial ceremony about 50,000 people, including aging victims who survived the bombing, gathered and observed a moment of silence.

The anniversary of the Hiroshima bombing was commemorated amid the growing threat of nuclear weapons propelled by Russia's invasion of Ukraine.
The issue poses a tricky balancing act for Kishida. Japan is traditionally an advocate of nuclear disarmament, in no small part because of the legacy of the attacks on Hiroshima and then Nagasaki three days later.
However, it also supports the partly nuclear-armed G7's group stance that members with atomic weapons shall retain them for as long as they're a necessary deterrent against other nuclear powers.
"World leaders have visited this city, seen its monuments, spoken with its brave survivors, and emerged emboldened to take up the cause of nuclear disarmament," he said in remarks read by a UN representative. "More should do so, because the drums of nuclear war are beating once again."
The American atomic bomb which was dropped on Hiroshima was nicknamed "Little Boy." It is thought to have killed as many as 140,000 people by the end of 1945. Three days later, the US dropped a second bomb on Nagasaki. It is believed to have killed up to 70,000 over the next four months.
A few days after the bombings, on August 15, Japan made an official announcement that it was surrendering. Soon after, on September 2, Japan formally capitulated, bringing an end to World War II in Asia.
Whether using the bombs brought about a speedier, and possibly even more bloodless, end to the war or whether it was an ultimately unnecessary show of force remains a fierce debate among historians almost eight decades on
