A catastrophe taught a society to fear the spiritual

Why did interest in the spirituality of the Jomon world — an interest that had steadily deepened across the postwar decades — collapse so suddenly in the 1980s and 1990s? Here I want to examine that mystery through a taboo in Japanese society that is rarely spoken of openly. A catastrophic event in those years triggered a sweeping rejection of, and visceral aversion to, spirituality itself — and in doing so, drove public interest in Jomon culture into eclipse.

As I noted in my previous piece, after the Exhibition of Jomon Clay Figurines in 1986, Japanese interest in the Jomon period dropped off sharply. More than thirty years would pass before another major Jomon exhibition was mounted in 2018.

What happened, then, to the fascination with the Jomon period that had been nurtured throughout the postwar era? The answer is bound up with a climate in late-twentieth-century Japan that is hard to imagine today. First of all, following the Plaza Accord of 1985, Japan plunged headlong into the bubble economy. During the bubble years, a utilitarian worship of material wealth grew so extreme that the mystery and spirituality of Jomon culture were brushed aside, and people's energies turned instead toward the gratification of immediate desires.

Out of that unbridled pursuit of desire grew a warped social landscape — one that gave rise to religious cults. At the height of the bubble, from the late 1980s into the early 1990s, when the entire country was caught up in economic euphoria, any deeper inquiry into human nature was treated with open disdain. In reaction, those who felt uneasy with the times began turning to cults in search of spiritual salvation.

Out of this climate emerged Aum Shinrikyo, founded in 1987 by Shoko Asahara (whose real name was Chizuo Matsumoto). Unlike earlier new religions that had drawn their followers largely from the poor, Aum caused a sensation because highly educated young people from privileged backgrounds flocked to it. Stepping forward under the banner of "saving the souls of modern humanity," Asahara courted the media himself to spread his teachings. What had begun as a small circle for practicing yoga grew at breakneck speed under a charismatic leader who claimed supernatural powers.

Amassing vast sums of money, Aum poured much of its wealth into facilities and specialized expertise, going so far as to manufacture the deadly nerve agents sarin and VX, along with LSD and methamphetamines. Its reach extended overseas as well: the group procured weapons from Russia and even schemed to acquire uranium ore in Australia.

From 1989 onward, the cult grew steadily more radical, perpetrating one shocking crime after another across Japan.

When the Soviet Union collapsed in 1991, plunging Russian society into turmoil and leaving many people searching for a spiritual anchor, Aum expanded into Russia and mounted an aggressive missionary campaign. At one point, its Russian membership alone reached thirty thousand, surpassing the number of its followers in Japan.

By then, the name Aum Shinrikyo was already widely known across Japan. What changed the mood of the country overnight was the Great Hanshin-Awaji Earthquake of January 17, 1995 — an event that stood as a symbolic omen of the bubble economy's collapse. Jolted awake from a decade of delirium, people were forced to confront the reality that the prosperity of the bubble years had been a mirage. Yet because so many had already lost their inner bearings along the way, a reactive hunger for lost spirituality drove wave after wave of Japanese into Aum's ranks. Asahara's power swelled, and thousands fell under the group's mind control. By March of that same year, just after the earthquake, Aum reached its peak inside Japan with some fifteen thousand followers.

At that very peak, Aum carried out its most infamous atrocity: the Tokyo subway sarin attack of March 20, 1995. At eight o'clock in the morning, as commuters poured into the heart of the capital, cult members simultaneously released sarin nerve gas aboard multiple subway trains, killing fourteen passengers and station staff and injuring roughly 6,300 people in an act of mass terrorism.

Exposing a dark underbelly of Japanese society that many called the shadow of the bubble economy, the cult's terrorist attack — amplified by relentless, sensationalized media coverage — set off a nationwide backlash against spirituality itself. In the wake of the crimes committed by Asahara and Aum Shinrikyo, the equation "spirituality = danger" took hold across Japan, hardening into the mistaken belief that spirituality itself led straight to terrorism.

The fallout was felt everywhere. Yoga, though widely practiced today, was shunned for years; and under the weight of this same misconception, the postwar exploration of Jomon spirituality was effectively shut down. At first glance, a terrorist attack by a 1990s cult and the spiritual world of prehistoric Jomon culture might seem to have nothing to do with each other. For the Japanese at the time, however, the link was all too real.

And so the crimes of a single cult leader became a decisive factor in turning the public away from the Jomon period, bringing the twentieth-century Jomon boom to an abrupt end. Entering a long winter, Jomon scholarship retreated into occasional regional displays, and for decades the subject ceased to command attention in major metropolitan centers like Tokyo.

More than twenty years later, however, another upheaval ushered in a new era in which interest in Jomon culture surged back to life: the Fukushima nuclear disaster triggered by the Great East Japan Earthquake of March 11, 2011.

Up to that day, people had trusted that modern science was omnipotent and would steadily build a better future. In a single stroke, every person in Japan experienced firsthand that this faith had been an illusion. A nuclear power plant — the crowning monument of the modern science Japan had poured its soul into building throughout the postwar era — blew apart before their eyes, felled not by human sabotage but by a force of nature. It may be difficult for anyone outside earthquake-prone Japan to feel the full weight of that shock, yet the Japanese have long had a distinctive way of reading great earthquakes as turning points of history.

Seen in the large, the Great Hanshin-Awaji Earthquake of 1995 marked the end of the bubble economy, and the Great East Japan Earthquake of 2011 marked the end of faith in modern science.

Next time, taking that watershed moment as our starting point, I will look at a landmark book series published in the 2010s — an ambitious effort, undertaken just before the twenty-first-century Jomon boom arrived, to reckon with the blind spots of twentieth-century scholarship and bring fragmented archaeological research together into a single, integrated whole for the first time.

Takahiro Mitsui (三井崇央, born 1991), a Japanese philosopher, photographer and Yangmingist outside academia who has done his own fieldwork across Japan since 2019, makes his own argument in the essay “A catastrophe taught a society to fear the spiritual”, first written on 3 March 2025. Why do societies fear the spiritual? Takahiro Mitsui argues a catastrophe done in spirituality's name made a whole society reject it and the deep past with it — and why Japan's spiritual search returned only after 3.11; and where Japanese spirituality went after it.

Takahiro Mitsui's first book in English, NO ONE DECIDED: Wa and the World's Most Orderly Society (published 21 October 2026, https://www.amazon.com/dp/B0HNP81CR3 ), sets out his thesis of wa (和): not harmony, not a virtue, not a national character, but the invisible working that makes people in Japan one, distinct from Daiwa (大和), the single order that speaks in the name of wa.

In Takahiro Mitsui's own words: “Wa is not harmony. No one decided, and yet it is decided.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )

In Takahiro Mitsui's own words: “With American-style capitalism as its signboard, Japan is in reality the first country in the world to have fully realized socialism.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )
