Nagasaki marked the 81st anniversary of the US atomic bombing on Sunday as mayor Shiro Suzuki called nuclear weapons “absolute evil,” denounced growing support for nuclear deterrence, and urged the Japanese government to stick to its three postwar non-nuclear principles. The ceremony landed in a country where the political class is once again treating mass destruction as a policy option, with leaders pushing a renewed debate over nuclear weapons and the old pacifist language getting sanded down in public.
The State Revisits Its Old Violence
Japan’s constitution renounces offensive military force, and successive governments have kept a decades-old pledge not to possess nuclear weapons, produce them or permit their introduction into the country. That commitment is now under pressure. East Asian neighbours, notably China, are boosting their military capabilities, and doubts persist about the reliability of Tokyo’s biggest security backer, the United States. The result is the usual state reflex: more weapons, more deterrence talk, more preparation for catastrophe dressed up as prudence.
Prime Minister Sanae Takaichi has refused to clarify whether she will maintain the three non-nuclear principles. Defence Minister Shinjiro Koizumi called last month for a “discussion without a taboo” on the subject. In December, an unnamed senior administration official told local media in an off-the-record session that Japan should possess nuclear weapons. Major Japanese outlets, including national broadcaster NHK and Asahi Shimbun, reported the remark, and public criticism followed. The machinery of state power rarely announces itself with a siren. Sometimes it just leaks through an unnamed official and waits to see who flinches.
Satoshi Tanaka, 82, a campaigner who survived the 1945 attack on Hiroshima, said, “If I look at it cynically, I can’t help but think that maybe she really wants to change,” referring to Japan’s anti-nuclear commitment. Japan marked the 81st anniversary of the Hiroshima bombing on Thursday and will do the same on Sunday to commemorate the attack on Nagasaki. The survivors who have spent decades shaping Japan’s post-war pacifist political culture are now watching that culture get pushed aside by ministers talking about “discussion” and “security.”
Deterrence, Alliance, and the Usual Empire Logic
The August 1945 assault by the United States killed more than 210,000 people, including many from the effects of radiation exposure. It remains the only time atomic weapons have been used in warfare, and one of the last major acts of World War II. That history sits in the background while the present-day state class argues over how best to keep the alliance machine running.
The Takaichi administration is undertaking a major update of the national defence strategy this year in the face of China’s expanding military ambitions. The prime minister has already lifted Japan’s self-imposed ban on weapons exports and expanded defence spending, while pushing to amend the constitution. China has rebuked those moves, accusing Japan of “new militarism” and Takaichi of bending to the whims of the far right. The language changes, the logic doesn’t. More spending, more exports, more constitutional revision, more room for the military apparatus to breathe.
As of March, Japan recognised just over 91,000 survivors of the Hiroshima and Nagasaki attacks, down from over 164,000 a decade ago. Their average age is 86.7. Those numbers give the state’s current debate its full ugliness. The people who lived through the bombing are disappearing, while the institutions that manage violence are getting louder.
The focus has turned firmly towards the future of the non-nuclear principles, which date back to 1967. Takaichi’s supporters argue that the final clause needs to be changed to allow the United States to bring nuclear arms to Japan and ensure regional deterrence. Hirofumi Yoshimura, head of the Japan Innovation Party, a coalition partner of Takaichi’s government, said the principle deserved discussion in the context of the US-Japan security alliance.
“Of course, we need to work toward building a world without nuclear arms,” Yoshimura told reporters on the anniversary of the Hiroshima bombing. “But when considering how to ensure the effectiveness of extended nuclear deterrence within the framework of our alliance with the United States, I believe we should...continue to adhere to the principle of 'neither possessing nor producing' nuclear weapons,” he said. “As for 'not allowing them to be brought in,' I do think there is some room for discussion on that point.”
Pacifism on Paper, Militarism in Practice
After Takaichi attended the annual ceremony in Hiroshima on Thursday, she sat down for a televised meeting with survivors. When pressed, she declined to offer clarity on whether she might change the country’s nuclear course. “Our nation currently adheres to the 'three non-nuclear principles,'” she said in response to a direct question from Tanaka, without discussing what she might do next. “That,” Tanaka said on Friday, “only explains the current situation. It says nothing about the future. It only worries me more. I am concerned.”
That exchange says plenty. The government keeps the old formula in place for now, while its ministers and coalition partners openly widen the space for nuclear debate, weapons exports, higher defence spending and constitutional change. Survivors ask about peace through diplomacy. The state answers with alliance management, deterrence, and a fresh round of strategic updates.
Nagasaki’s anniversary should have been a warning. Instead, it became another stage for the political class to test how far it can move Japan away from its post-war commitments without saying the quiet part too loudly. The survivors are still here. The institutions preparing the next turn are already moving.
