Japan has neither of such weapons. And yet, Japan is labelled 'new militarism'.
At the Shangri-La Dialogue in Singapore, Japan's defence minister Shinjiro Koizumi pushed back against Beijing's accusations of resurgent militarism, arguing that a nation without nuclear weapons or strategic bombers cannot credibly be cast as the aggressor. The exchange reflects a deeper civilizational reckoning: Japan, long defined by post-war restraint, is quietly rewriting its own identity under Prime Minister Takaichi, while China — itself engaged in rapid, opaque military expansion — finds the transparency of Japan's ambitions more unsettling than the ambitions themselves. What unfolds between these two powers may determine whether Asia's security order bends toward managed competition or breaks toward something far less predictable.
- Japan's defence minister publicly dismantled Beijing's 'new militarism' charge at Asia's premier security forum, calling it a false accusation from a nation that possesses hundreds of undisclosed nuclear warheads.
- China's fury has been building since Prime Minister Takaichi openly declared Japan might intervene militarily if Beijing attempts to seize Taiwan by force — a statement of intent that rattled Beijing more than any weapons system.
- Beijing sent a reduced delegation to the Shangri-La Dialogue and excluded its own defence minister for the second straight year, leaving a conspicuous silence where direct diplomacy might have cooled tensions.
- Japan is pressing forward with modernization across AI, unmanned systems, cyber, and space defence — framing transparency itself as the moral distinction between Tokyo's buildup and Beijing's.
- Neither side is prepared to accept the other's narrative, and the region watches to see whether a more assertive Japan stabilizes the balance of power or accelerates the confrontation both capitals claim to fear.
Standing before the Shangri-La Dialogue in Singapore on Sunday, Japan's defence minister Shinjiro Koizumi turned Beijing's accusations of militarism back on their source. Japan, he noted, possesses no nuclear weapons, no strategic bombers, no weapons of mass destruction — and yet it is Tokyo being labeled the aggressor. The charge, he implied, was difficult to sustain against a China that has spent years expanding its own arsenal behind a veil of opacity.
The confrontation has been months in the making. Under Prime Minister Sanae Takaichi, Japan has moved decisively away from the post-war pacifist tradition that defined it for nearly eighty years. Encouraged by Washington and driven by genuine anxiety about Chinese intentions, Tokyo has begun openly discussing the possibility of military intervention should Beijing attempt to take Taiwan by force. It was Takaichi's November remarks on that subject that most inflamed Beijing — not because Japan had the capability, but because it had the candor.
Koizumi's argument at the forum was essentially one of contrast: China holds hundreds of nuclear warheads and expands its forces without adequate transparency, while Japan modernizes openly, communicating its progress in artificial intelligence, unmanned systems, cyber warfare, and space defence. 'Japan's past as a peace-loving nation has been valued by the region and by the international community,' he said. 'This fact will not be shaken by false claims, because it is a fact.' The words carried the weight of a country that knows its history and is asking to be judged on what it has become.
The forum's composition told its own story. Japan and the United States sent full delegations; China sent a reduced team and, for the second consecutive year, left its defence minister at home. Koizumi noted the absence with diplomatic regret, a courtesy that quietly measured how far the relationship had deteriorated.
What neither side has resolved is whether the other can be trusted. Japan frames its buildup as a rational response to a shifting threat environment. China sees a former militarist power discarding its restraints. Both readings hold partial truth, and the region now waits to learn whether Asia can absorb a more assertive Japan without producing the very instability each country insists it wishes to prevent.
Shinjiro Koizumi stood before Asia's most important defence gathering on Sunday and turned Beijing's accusations back on themselves. Japan's defence minister, speaking at the Shangri-La Dialogue in Singapore, rejected what he called the false claim that Tokyo was pursuing a dangerous new militarism. The charge, he suggested, was absurd on its face: Japan possesses no nuclear weapons, no strategic bombers, no arsenal of weapons of mass destruction. Yet somehow, he said, it was Japan being labeled the aggressor.
The tension between Tokyo and Beijing has been building for months, sharpened by Prime Minister Sanae Takaichi's willingness to break with Japan's post-war pacifist tradition. Under her leadership, Japan has moved decisively toward a more assertive defence posture, encouraged by the United States and driven by genuine security concerns about China's intentions in the region. This shift represents one of the most significant changes in Japanese security policy in decades—a country that spent nearly eighty years defining itself through restraint is now openly discussing military intervention in Taiwan's affairs if Beijing attempts to seize the island by force.
China has responded with fury. Beijing has repeatedly accused Tokyo of reckless militarism that threatens regional stability. The diplomatic friction intensified after Takaichi's November comments about potential Japanese military action over Taiwan, the self-governed island that China claims as its own territory. What rankled Beijing most was not the military capability Japan possessed, but the willingness to state openly what it might do with it.
Koizumi's response at the Shangri-La Dialogue cut to the heart of the dispute. He pointed out that China possesses hundreds of nuclear warheads and has been rapidly expanding its military capabilities in recent years—all while operating with what Tokyo sees as insufficient transparency about its intentions. Japan, by contrast, was building up its defence systems openly, with clear communication about its modernization efforts in artificial intelligence, unmanned systems, cyber warfare, and space defence. The difference, he argued, was not one of ambition but of honesty.
"Japan's past as a peace-loving nation has been valued by the region and by the international community," Koizumi said. "This fact will not be shaken by false claims, because it is a fact." It was a statement that acknowledged Japan's historical burden—the weight of its militaristic past—while asserting that the country had earned the right to be trusted in its current intentions.
The forum itself reflected the widening gap between the two powers. The Shangri-La Dialogue brings together security officials and defence experts from roughly 45 countries, making it the premier venue for discussing Asian security challenges. Japan and its American ally sent full delegations. China, by contrast, sent a reduced team that notably excluded its defence minister, Dong Jun, for the second consecutive year. Koizumi expressed disappointment at the missed opportunity for direct conversation, a diplomatic courtesy that underscored how strained the relationship had become.
What remains unresolved is whether either side can convince the other of its true intentions. Japan argues it is simply adapting to a changing security environment, modernizing its forces to meet genuine threats. China sees a former militaristic power shedding its pacifist constraints and preparing for confrontation. Both narratives contain elements of truth, and neither side appears ready to accept the other's framing. The question now is whether the region can accommodate a more militarily assertive Japan without triggering the very instability that both countries claim to want to avoid.

The Hearth Conversation Another angle on the story
Why does Japan's defence minister feel the need to make this argument at all? If Japan's intentions are truly peaceful, shouldn't that be self-evident?
Because intentions are never self-evident in international relations. Japan is fundamentally changing what it's willing to do militarily, and that change looks different depending on where you're standing. From Tokyo's perspective, it's a necessary adaptation. From Beijing's perspective, it looks like a country finally revealing its true ambitions.
But Koizumi's point about nuclear weapons seems almost too simple. Surely China's concern isn't just about raw firepower?
No, it's not. The nuclear comparison is rhetorical cover. What really worries Beijing is that Japan is now openly discussing military intervention over Taiwan. That's the real shift. Japan used to be constrained by its pacifist constitution and public opinion. Now it's breaking those constraints with American backing. That's destabilizing from China's perspective, regardless of how many warheads either side has.
Why did China send such a weak delegation to this forum?
That's the question, isn't it. Officially, it's probably just scheduling or diplomatic pique. But it also sends a message: we're not interested in dialogue right now. By keeping their defence minister away for a second year, they're signaling that they don't see much point in direct conversation with Japan or the West about these issues.
So where does this end? Can Japan really rebuild its military while maintaining its reputation as a peace-loving nation?
That's the central tension. Japan is betting that transparency and restraint in how it builds up will preserve its credibility. But China is betting that any military buildup by Japan is inherently threatening. Those two bets are on a collision course, and there's no obvious way to resolve it except through time and demonstrated behaviour.
