History is the heat of your own time

Is the motherland merely an afterimage—the phantom remnant of an illusion and a reality that once possessed tactile weight? Why is it that human beings can live on, clutching nothing but these afterimages? These questions have occupied my mind of late. I feel that the question of the motherland is one that everyone will soon be forced to confront, and that it inevitably reopens the deeper inquiry: who am I? In yesterday’s essay, I reflected on my own motherland, Japan, tracing the historical arc before and after the Second World War—especially the postwar economic reconstruction—and examining through the lens of Japanese cinema the forces that forged this potent residual image.

Yet as I noted yesterday, no matter the medium—whether books, still photographs, or film—one can catch the wind and scent of an era only up to a point; one can never touch the live heat at its core. That heat can only ever be experienced by standing in that place, in that time. This is the inescapable boundary of history. The only history any human being can truly know is rooted in their own singular life: in which era they were born, where they grew up, and where they stand today.

While I cannot put into words the heat of the youth of the late 1930s or late 1960s, I can articulate the heat of the era I have lived through myself. In my case, my life coincided with the "Lost Decades," the period when that fierce heat that once enveloped Japan drained away, replaced by a slow, inexorable chill. Deluded into believing that economic growth was the sole future, the previous generation turned a blind eye to the fundamental questions of sovereignty and national independence, pushing problems down the road on the assumption that material prosperity forgave everything. Here is the true nature of the debt accumulated within the afterimage of the motherland.

Yet as the citizens of advanced nations came to understand over the course of the twentieth century, human beings cannot attain genuine peace through economic prosperity alone. While an economic foundation is indispensable for basic survival, the scale of twentieth-century prosperity became excessive, contributing nothing to the spiritual cultivation of the individual. As I turn over the problem of the motherland, postwar Japan seems to offer the clearest possible cautionary tale. In Europe, individualist traditions preserved space to question the meaning of human existence alongside critiques of material excess; Japan, by contrast, discarded those questions from the outset, erecting a social architecture driven by profit maximization to an extent seen almost nowhere else.

This divergence is closely tied to the fact that postwar Japan's patron was the United States rather than Europe. Japan’s economic prosperity rested upon a fatal deception: it was not actively achieved through the independent spirit of a sovereign state. The primary reason Japan realized such dramatic growth in the latter half of the twentieth century was that Washington, locked in conflict with the Soviet Union, designated Japan as its final fortress in Asia, a bulwark against communism. As a consequence, Japan outsourced its national defense entirely to the US military, brandishing "peace" and demilitarization as a convenient facade while pouring every national resource into economic expansion. Worse, that very expansion was built upon the tragedy of the Korean War on its neighbor's soil.

The fundamental issue, however, lay in the intoxicating illusion of perpetual economic growth. While it is obvious that every rise is inevitably followed by decline, Japan was blinded by the fantasy, letting its appetites run wild until it became incapable of stepping back to think with composure. Once national economic strength had been attained, the logical path for postwar Japan would have been to rebuild its own defense capabilities and work toward the complete withdrawal of US forces over several decades, thereby achieving authentic sovereignty and independence. Instead, a Japan blinded by greed and a US military apparatus addicted to the privileges of occupation entered into tight collusion, refusing to relinquish their vested interests and quietly strangling Japan's autonomy.

Despite attaining an economy rivaling the victors of the Second World War, Japan evaded the responsibilities of independence expected of an advanced nation, deploying "peace" as a weapon to resist all change. Consequently, countless issues that should have been resolved sixty years ago still reign supreme today, entirely untouched. Here lies the true cause of Japan’s decay: the crisis did not begin yesterday; it was set in motion six decades ago.

I was born in 1991, in the wake of that older generation’s defeat and the resignation that followed. In American terms, this corresponds to the peak of the Millennials; in Japan, it coincided with the demographic slide into population decline and the bursting of the economic bubble—the onset of loss. What took place around that threshold? Readers who visited Japan in that era would likely be bewildered by the stark contrast between the Japan of then and the Japan of today. That bewilderment is shared by Japanese and foreigners alike. In that gulf lurks the shadow of the motherland's afterimage.

Postponing these problems meant allowing the appetite for economic growth to consume the citizenry entirely. A relentless logic of profit was drilled into a population of one hundred million, while spiritual cultivation was cast aside. It is true that the Allied occupation deliberately dismantled traditional Japanese spirituality, fearing its wartime expressions, but that did not mean all possibility of spiritual growth was extinguished. This deep rift—between unbridled profit-seeking and the collapse of spiritual cultivation—remains the central dilemma inherited by twenty-first-century Japan. The real question is whether Japan has the capacity, or even the will, to resolve it on its own.

Looking back shortly before my birth, the Plaza Accord of 1985 and Japan’s descent into the bubble economy were triggered by rising "Japan Bashing" in the United States, which forced Washington to act. This resentment grew from the spectacle of a country that outsourced one hundred percent of its defense to the American military while focusing entirely on economic expansion, until its corporate power threatened the American economy itself. At that time, many in the West still remembered the war; emotionally, it was intolerable that a defeated adversary should surpass the United States in economic might.

Japan was thus steered toward an inflated bubble economy, plunging into an era of frenzy. Because this economic mirage was rooted in raw materialism, the entire nation threw itself into celebrating profit day and night. Stripped of spiritual grounding, the Japanese devolved into a people who could evaluate existence only in monetary terms. Because that success had been so overwhelming, their addiction to the illusion of endless growth ended up destroying the future of the generations that followed. Two events symbolized that turning point: the collapse of the Soviet Union and the dawn of the personal computer era marked by Windows 95. The former presaged globalization; the latter launched the digital revolution. Yet toward both tides of the new era, Japan turned away, retreating into resistance.

Anyone familiar with Japan back then might find this baffling. Was Japan not once celebrated for its mastery of digital technology, famous for launching ambitious products and services? Why is today’s Japan the exact reverse—technologically illiterate, unable to produce goods that catch the world’s eye, with a digital fluency unworthy of an advanced nation? That perception is accurate. I find the shift astonishing myself: where did that boundless curiosity go, that talent for rapidly absorbing new ideas and remixing them into groundbreaking hardware and software? The answer lies in the mid-1980s.

On August 12, 1985, just before the signing of the Plaza Accord on September 22, a forgotten event sealed the fate of Japan’s digital future. Around 1983, Ken Sakamura, then a research assistant at the University of Tokyo, proposed TRON (The Real-time Operating system Nucleus) as an embedded real-time operating system. Anticipating what we now call the Internet of Things, TRON was an ambitious project to develop a domestic operating system capable of competing globally. Most people today have never heard of TRON, yet its architecture had the potential to outstrip the Windows ecosystem that later captured the personal computer market.

Three powerful domestic adversaries lined up to kill it. First came SoftBank, which relied on spreadsheet software for its core profits and feared TRON’s capabilities; second was NEC, anxious that its PC-98 sales network running Microsoft software would be undercut; and third was the Ministry of International Trade and Industry (now METI), where bureaucrats aligned with American interests panicked when the Ministry of Education proposed introducing TRON-based computers into elementary schools nationwide, lobbying Washington to intervene.

Prompted by these domestic lobbyists, the United States took the extraordinary step in 1989 of placing TRON on the Super 301 retaliatory trade list, threatening severe sanctions against what it deemed unfair trade practices. TRON’s global ambitions were gutted. Historians of computing often wonder why TRON failed to become a world standard; the reality is that Japan strangled its own operating system from within.

Yet alongside the bureaucratic sabotage of TRON, an entirely different event occurred on that same date: August 12, 1985. Japan Airlines Flight 123, carrying 524 passengers and crew, crashed into Mount Osutaka, killing 520 people. The official investigation was notoriously sloppy, giving rise to countless theories hovering between fact and conspiracy. Notably, seventeen engineers connected to the TRON project were on board (all perished), and the project leader, Sakamura, later confirmed he would have been on that flight had his schedule not changed.

Toko Aoyama, a former JAL flight attendant who refused to accept the official explanation of her colleagues' deaths, spent decades investigating the disaster, publishing new findings in 2017. Her research documented multiple eyewitness reports of two Self-Defense Force Phantom jets pursuing the airliner just before it went down. Although it has long been known that the discovery of the crash site was mysteriously delayed until the following morning, the military has never accounted for its actions during those crucial hours. Aoyama reported that the wreckage reeked of gasoline and tar, and that the victims' bodies were charred to a degree impossible in a standard aviation accident. Military flamethrowers use gelled fuel containing gasoline and tar, pointing to the disturbing possibility that someone incinerated the site to destroy evidence before dawn, killing many who had survived the impact. Photographs taken through the plane's windows shortly before the crash revealed an orange object flying toward the fuselage—at the time, Japanese Self-Defense Force test missiles were painted bright orange.

Theories persist: one suggests the plane was brought down to protect American tech hegemony; another points to an accidental missile strike by military aircraft. Prime Minister Yasuhiro Nakasone adamantly refused to disclose the truth, repeatedly declaring he would "take the secret to the grave"—a vow he kept until his death in 2019. The full truth remains unknown, though it may one day emerge from declassified American archives.

In the shadow of that suspicious crash and the public distrust bred by official silence, the Plaza Accord was signed a month later. Swept up in the frenzy of speculative wealth, the incident was buried. People turned their attention from uncovering truth to chasing money—a classic regime of bread and circuses. It revealed that for the Japanese, private enrichment mattered far more than confronting state corruption. Having attained national affluence, the populace once again abandoned spiritual cultivation, snuffing out the last turning point with their own hands. Following the military defeat of 1945, Japan suffered a second defeat in the economic sphere—a capitulation that squandered the future by gorging on the memories of past glory. Thus began the thirty lost years.

Around 1991, the year of my birth, the first cracks appeared in the bubble economy, though its total unraveling took another seven years. Until the late 1990s, an intense heat still lingered among the Japanese. Growing up, I vividly remember the adults around my father; they seemed to radiate immense vitality. However distorted by materialism, Japan still had momentum. That wind, that scent, that brightness in the adults around me formed my primal experience. Because I carry that memory, I feel compelled to confront the question of how my motherland could have fallen into such ruin in a mere three decades.

In that strange blend of 1990s decadence and encroaching loss, the Japanese lost their bearings, and with them, the future of the nation. The natural Japanese talent for rapid learning and technological adaptation vanished, replaced by an entrenched aversion to novelty: any sign of innovation was smothered in the cradle. A prime symbol of Japan’s surrender in telecommunications was Al Gore’s Information Superhighway, which took NTT’s earlier VI&P concept and turned it into the Clinton administration’s National Information Infrastructure (NII) in 1993, laying the cornerstone of American digital supremacy. Washington bet heavily on the digital future; Japan, having conceived the idea, failed to act. This was Japan’s third defeat at American hands: military in 1945, economic in the 1980s, and technological in the 1990s.

Reflecting on the years around my birth, the outlines of what history and the motherland mean begin to emerge. In yesterday's essay, I described the wind, scent, and scorching heat felt across the movie screen—qualities that mirror my own childhood impressions. Yet in everyday life, I have walked through a chilled landscape resembling a field of ruins left behind when that heat died. To know the heat, yet to live in a world without heat: this strange condition may be the true nature of the loss I feel toward my country. When I ask whether the aspirations of earlier youth—their hunger for the future, their conviction that the world could be remade—reach across time to touch us today, I feel only rupture. Their fire was extinguished, leaving us standing paralyzed among the cold ashes. Readers elsewhere will recognize this grief: thirty years is more than enough to cruelly transform a motherland, whether in Japan, the United States, or Britain.

This rupture is even more absolute for the generation younger than mine. Here is the harshest truth facing contemporary Japan: the texture of the country fundamentally changed in the mid-1990s. For me, the motherland still refers to the Japan that existed up to that watershed, where faint echoes of heat and struggle survived. Whenever people discuss "Japan," they unconsciously summon an image anchored before that divide. But those in their twenties or younger know nothing of that country. They were born into a world without heat.

By the time they arrived, Japan had already settled into stagnation, wrapped in an atmosphere of suffocating deadlock. They have never known the dynamism of an earlier Japan that proactively shaped its future, hungrily absorbed the best from abroad, and turned out ambitious creations. To them, Japan has always been a sterile, frictionless space, governed not by yearning for what might be, but by the anxious preservation of what is. Status-quo preservation—clinging to the afterimage of Japan—became national policy, and the populace domesticated itself into that system. For better or worse, my parents’ generation stood at the threshold of that domestication, resisting it long enough through the mid-1990s to appear luminous to my childhood eyes.

For today’s youth, the heat with which people once took to the streets and wagered their lives to change the world is merely an entry in a history textbook, lacking all tactile reality. I cannot even share my sense of loss with them, because for them, absence is the default; they never knew the state before the fall. To them, the afterimage is Japan, but it has no texture. It is an untouchable homeland—which is to say, they have no motherland at all. This realization struck me forcefully: why do young people across advanced nations hate and attack their own countries so fiercely? Older generations find it incomprehensible, but this is where their cry begins.

Raised in a sanitized society stripped of wind and scent, they live severed from the primal energy of the soil and the fierce individual impulse to rebel against it. An unbridgeable chasm yawns between what I call the motherland—the object of my own ambivalence—and the abstract symbol they know as Japan. That cognitive rupture deepens my loneliness and reinforces my conviction that the motherland is dead. The shared landscape of origin no longer exists. This is the domestic intergenerational struggle currently shaking advanced nations.

The United States is unique among developed nations in that generational succession continues; as Millennials and Gen Z become the voting majority by 2028, the presidential elections of 2028 and 2032 will bring profound political realignments. But Japan and Europe are trapped in aging societies that cannot renew their values through generational turnover. Unable to channel generational friction into political reform, Japan and Europe must stumble forward within these constraints. The young have no outlet, powerless against demographic numbers that enshrine status-quo preservation.

In a super-aged society where the elderly form the decisive majority, public opinion is easily steered by media management anchored at Yokota Air Base. The values and voices of the young are completely disregarded. To those outside Japan, this complete disenfranchisement may seem incredible, but it is literal truth: the youth are ignored because Millennials and Gen Z remain a demographic minority.

The framework of the state and society we call Japan came to an end in the mid-1990s. The older Japan that held historical continuity, pregnant with heat and struggle, died back then. Today’s Japan is either its hollow shell or a different country entirely, run on different principles. That the younger generation lives inside that shell without ever knowing the old fire is the clearest proof that this death is irreversible.

We face the cold necessity of admitting that the motherland is now only an afterimage. To move toward the future, one ritual alone is required: the acceptance of death. We must acknowledge that the motherland is gone. We must toll the funeral knell for the country we once loved, took pride in, and clung to even while despising it.

"Kill the motherland."

The words sound harsh, even ominous. Yet this is no call to destruction. It is faith in the immutable truth that regeneration follows only upon death. We must face the fact that our beloved motherland no longer holds the shape of a home, and attend its passing in our hearts. We must cease clinging to the afterimage of an old illusion and bring it to a close. Only in the deep quiet on the other side of that despair will the first green shoots of renewal appear.

The heat and scent of the cinema I have traced across these two essays are not relics for idle nostalgia. They are the embers from which we can kindle a new fire with our own hands, upon the grave of the motherland we have buried and mourned. To believe that regeneration always follows death: for all who suffer the grief of seeing their homeland cease to be a home, that pain is the true starting point from which a new horizon begins.
