Japan has neither nuclear weapons nor strategic bombers. Why is it labelled militarist?
At a defence summit in Singapore, Japan's Defence Minister Shinjiro Koizumi pushed back firmly against China's accusations of 'neo-militarism,' inverting the charge by pointing to Beijing's nuclear arsenal and lack of military transparency. The exchange captures a deeper struggle: a nation redefining itself after eight decades of constitutional pacifism, watched closely by neighbours who carry the memory of a very different Japan. As Tokyo accelerates its rearmament and contemplates revising Article 9, the question is not merely one of defence budgets, but of how nations carry — and are carried by — their histories.
- China's accusation that Japan is a 'grey rhino of remilitarisation gathering speed' deliberately invoked the spectre of imperial conquest, landing as a calculated provocation before an audience of nations Japan once occupied.
- Koizumi's rebuttal was sharp and unapologetic — he turned the militarism charge back on Beijing, citing China's nuclear arsenal and opaque defence spending as the true regional threat.
- Japan's rearmament is not rhetorical: twelve consecutive years of record defence budgets, new missile systems, drone programmes, and loosened weapons export rules signal a structural shift in Tokyo's strategic posture.
- At home, the transformation is fracturing Japanese society, with some of the country's largest anti-war protests in decades erupting over plans to revise the pacifist Article 9 and the fear of abandoning a post-war identity built on restraint.
- Both nations are navigating unhealed historical wounds — wartime atrocities, inadequate apologies, and long memories — making every military exchange also a confrontation with the past.
At a defence summit in Singapore, Japan's Defence Minister Shinjiro Koizumi delivered Tokyo's sharpest public rebuttal yet to Beijing's accusations of militarism — doing so before an audience that included officials from nations Japan had invaded during World War Two. Days earlier, China's defence ministry had warned that a 'remilitarised Japan' was 'gathering speed,' invoking the language of imperial history to call on the world to contain what it termed Japan's 'neo-militarism.' Koizumi rejected the charge outright, calling it nothing further from the truth.
His counter-argument was a deliberate inversion: Japan, he noted, has no nuclear weapons and no strategic bombers. China, by contrast, maintains a large arsenal of both. He framed Japan's defence expansion as a transparent and proportionate response to regional challenges, and pledged continued dialogue with neighbours — even as he declined to address a Chinese representative's pointed question about wartime apologies, pivoting instead to criticism of Beijing's own military opacity.
The rearmament Koizumi was defending is real and accelerating. For twelve consecutive years, Japan has set new defence spending records, with the latest budget exceeding $57 billion and pushing toward the 2% GDP threshold. Under Prime Minister Sanae Takaichi, who took office in late 2025, the buildup has expanded to include new missile systems, unmanned drones, and liberalised weapons exports. Takaichi has also signalled plans to revise Article 9 — the pacifist clause that has defined Japan's post-war identity for nearly eighty years.
That prospect has divided Japanese society deeply. Some citizens see stronger defences as a necessary hedge against Chinese pressure; others fear the country is drifting toward confrontation and abandoning a hard-won commitment to peace. Anti-war protests, some of the largest in decades, have swept across the country in recent months. The historical dimension adds further weight: Japan's wartime conduct in China left wounds that have never fully healed, and Beijing has long found Tokyo's apologies inadequate.
Whether Japan's strategic pivot leads to greater stability or deeper regional tension remains an open question. What is already clear is that the rhetorical temperature between Tokyo and Beijing is rising — and the unresolved histories beneath it are rising with it.
At a defence summit in Singapore on Sunday, Japan's defence minister Shinjiro Koizumi delivered what may be Tokyo's sharpest public rebuttal yet to Beijing's accusations of militarism. Standing before a room of Asian officials—many from nations Japan had invaded during World War Two—Koizumi rejected the charge outright, turning the argument back on China with pointed language about nuclear arsenals and military opacity.
The exchange marks an escalation in a dispute that has been building for months. Just days before the Singapore gathering, China's defence ministry spokesman Jiang Bin had warned that "the grey rhino of a remilitarised Japan is gathering speed" and called on the world to contain what he termed Japan's "neo-militarism." The accusation stung because it invoked the spectre of imperial Japan, a historical wound that remains raw across East Asia. Koizumi's response was direct: the label was "nothing further from the truth."
Japan has indeed been rearming at a steady pace. For twelve consecutive years, the country has set new defence spending records. The most recent budget, approved in December, exceeds 9 trillion yen—roughly $57 billion—pushing Japan closer to its stated goal of spending 2 percent of GDP on military capacity. Under Prime Minister Sanae Takaichi, who took office in October 2025, this buildup has accelerated. The government is investing in new surface-to-ship missiles, unmanned drones for land and underwater deployment, and has recently loosened restrictions on selling lethal weapons to other countries. Takaichi has also signalled her intention to revise Article 9 of Japan's constitution, the pacifist clause that has defined the nation's post-war identity.
Koizumi's argument in Singapore rested on a simple inversion. Japan, he said, possesses neither nuclear weapons nor strategic bombers. China, by contrast, maintains what he called a "huge arsenal" of both. So why, he asked, was Japan being branded as the militarist threat? He framed Japan's defence upgrades as a natural response to regional challenges and promised the international community that Tokyo would proceed "with a high degree of transparency" and maintain constant dialogue with neighbours.
When a Chinese military representative pressed him on whether Japan would apologise for wartime atrocities—a question that has festered in bilateral relations for decades—Koizumi sidestepped it. Instead, he pivoted to criticism of China's military expansion and what he described as insufficient transparency in Beijing's defence spending and capabilities. "China's external approach and military activities are matters of serious concern for Japan and the international community," he said, before adding that Japan's door remained open for communication.
The tension between the two countries runs deeper than current military posturing. Japan's invasion of China during the 1930s and 1940s left scars that have never fully healed. China has long viewed Japanese apologies as inadequate, and the question of historical accountability remains a flashpoint. Koizumi's father, Junichiro, issued several apologies when he served as prime minister, but Beijing has repeatedly found them insufficient.
Back home, Takaichi's defence agenda has fractured Japanese society. Some citizens support stronger military capacity as a hedge against Chinese pressure and other regional threats. Others worry that the buildup risks escalating confrontation and represents a dangerous departure from post-war pacifism—a principle that has anchored Japan's national identity for nearly eighty years. In recent months, anti-war protests have erupted across the country, some growing into Japan's largest demonstrations in decades. The debate over Article 9 revision has been particularly fierce, with critics arguing that abandoning the pacifist clause would represent a fundamental break with the past.
Koizumi's remarks in Singapore suggest that Tokyo intends to press ahead regardless. The government is revising key security documents by year's end and has already begun reshaping Japan's defence industrial base. Whether this path leads to greater regional stability or to deeper confrontation remains unclear. What is certain is that the rhetorical temperature between Tokyo and Beijing continues to rise, and the historical grievances that fuel it show no sign of cooling.

The Hearth Conversation Another angle on the story
Why does China keep calling Japan militarist when Japan doesn't have nuclear weapons?
Because the accusation isn't really about weapons inventories. It's about trajectory and intent. China sees Japan moving away from seventy years of pacifism, loosening arms sales rules, talking about constitutional revision. From Beijing's view, that's the militarism—the direction of travel, not the current arsenal.
But Koizumi has a point, doesn't he? China does have a much larger military.
He does, and that's precisely why the argument is so charged. Both sides are right about the facts. China's arsenal is vastly larger. Japan's spending is accelerating. Neither country is lying; they're just emphasizing different truths to make different cases.
What about the apology question? Why did Koizumi dodge it?
Because there's no answer that satisfies both sides. China wants acknowledgment of wartime atrocities; Japan has apologised multiple times but China says it's never enough. Koizumi sidestepped because engaging would only deepen the wound. Easier to change the subject to China's current behaviour.
Is the domestic opposition in Japan serious?
Very. These aren't fringe protests. Some have been the largest anti-war demonstrations Japan has seen in decades. A lot of Japanese people are genuinely frightened that their country is abandoning the one thing that made it different after the war—the commitment to pacifism. That fear is real and it's widespread.
So where does this end?
That's the question nobody can answer yet. Japan seems committed to the defence buildup and constitutional revision. China will keep objecting. The protests will continue. The historical wounds won't heal. Everyone's locked into their position, and the rhetoric keeps getting sharper.
