Japan marked the 81st anniversary of the U.S. atomic bombing of Nagasaki on Sunday, August 9, 2026, amid intensifying debates over the country’s long-standing security posture and non-nuclear commitments.
Prime Minister Sanae Takaichi opened debate on the country’s postwar non-nuclear principles amid increasing doubts over the reliability of the US security umbrella as China flexes its military muscles in the region.
Attendees at Nagasaki Peace Park observed a moment of silence at 11:02 a.m., marking the exact moment when the U.S. dropped the “Fat Man” plutonium bomb, killing an estimated 74,000 people.
The U.S. launched the Nagasaki attack on August 9, 1945, three days after the bombing of Hiroshima, which killed an estimated 140,000 people.
Six days later, Japan surrendered on August 15, 1945, ending World War II and nearly half a century of Japanese aggression across Asia.
Following the catastrophic event, Nagasaki’s Mayor Shiro Suzuki also delivered a sharp rebuke of nuclear deterrence theory, declaring nuclear weapons an “absolute evil” rather than a “necessary evil”.
Suzuki singled out the Japanese government, demanding it uphold Japan’s war-renouncing constitution, attend the Treaty on the Prohibition of Nuclear Weapons review conference later this year and stick to the three non-nuclear principles.
He directly urged the central government to stick strictly to its pacifist constitution.
Takaichi supports the first two principles of not possessing and developing nuclear weapons.
The Japanese prime minister reiterated her policy of taking “a realistic and pragmatic approach” toward achieving a world without nuclear weapons.
As she did in Hiroshima, Takaichi remained ambiguous about the three non-nuclear principles and only reiterated that Japan currently maintains the policy.
As reported by Japan Times, the anniversary comes as Japan’s government pursues defense policy revisions to boost offensive military capabilities.
The strategic ambiguity has fueled political debate across Japan regarding whether Tokyo should reevaluate nuclear deterrence arrangements or allow regional sharing amid escalating security threats in East Asia.
Prime Minister Sanae Takaichi was urged on Sunday to officially recognize more hibakusha survivors of the Aug. 9, 1945, U.S. atomic bombing of Nagasaki.
Some people who were exposed to radiation from the bomb have not been officially recognized as hibakusha because they were outside locations designated as being in the blast zone by the government.
Head of the Nagasaki Atomic Bomb Survivors Council, Shigemitsu Tanaka informed Takaichi, “Time is limited for us, so we seriously ask you to make a Cabinet decision on support measures for both” recognized and unrecognized survivors.”
In response, the Japanese Prime minister said only that the government “has been providing unrecognized hibakusha with medical expense subsidies on par with aid to recognized hibakusha and will continue steadily implementing such support.”
