Japan’s defence minister, the plain-spoken Itunori Onodera, has issued a stark warning: the nation must arm itself with ‘critical’ urgency. His words, delivered in Tokyo, saw the UK and Japan deepen their security pact, a move that feels less like a diplomatic handshake and more like a survival instinct. The language is telling. ‘Critical’ is the word of the moment, a word that hints at a world where the stakes are no longer theoretical.
Onodera’s plea is a far cry from post-war Japan’s pacifist constitution, a document that has shaped the nation’s identity for decades. Yet here we are, watching a country that once rejected the very notion of militarism now urgently discussing missile systems and joint patrols. The UK pact, signed by Prime Minister Rishi Sunak and his Japanese counterpart Fumio Kishida, allows for reciprocal troop deployments. For the first time since the Second World War, Japanese and British soldiers will train together on each other’s soil.
On the streets of Tokyo, the reaction is mixed. At a café in Shinjuku, I spoke with Yuki Tanaka, a 34-year-old office worker. ‘I understand the need for security,’ he said, stirring his coffee. ‘But this feels like a new direction. My grandparents would be horrified.’ His sentiment echoes a broader anxiety: the human cost of shifting from a defensive to an offensive posture. The Japanese public, long accustomed to the ‘peace constitution’, is being asked to accept a new reality.
Meanwhile, in London, the pact is being sold as a logical extension of ‘Global Britain’. But walk through the Ministry of Defence’s corridors, and you sense a different urgency. The war in Ukraine has recalibrated every calculation. If a major European power can be invaded, why not an island nation? The pact is a hedge, a bet that alliances are the only reliable currency in a volatile world.
Yet there is a cultural shift beneath the geopolitics. Japan’s pacifism was never just a legal stance; it was a core element of national identity, a rebuke to its own militaristic past. Now, as the country arms up, it grapples with a profound psychological change. The ‘human element’ is palpable: families discussing conscription possibilities, schoolchildren learning emergency drills. The security pact may be about missiles and troops, but its real impact is in the daily lives of citizens.
Class dynamics also play a role. The decision to arm is driven by elites, but the burden will fall on the young and the working class, those who will serve in the new forces or face the economic consequences of increased defence spending. The wealthy can buy security; the rest must rely on the state. This is the unspoken tension of every defence bill: who pays, and who fights?
Onodera’s warning is a mirror. It reflects a world where the old certainties have evaporated, where even the most peaceful nations must fortify. The UK-Japan pact is a symptom, not a solution. And as the human cost mounts, we must ask: what does it mean to live in a world where ‘critical’ is the new normal? The answer, I suspect, lies not in military manuals but in the quiet conversations of ordinary people, trying to make sense of a future that feels increasingly fragile.
