When the staple fails, so does the order

Tomorrow, on July 20, the Japanese electorate heads to the polls for the twenty-seventh House of Councillors election, and the mass media is saturated with coverage. Among the pivotal issues of this campaign is one that touches the very foundation of daily life: rice. Since last autumn, the country has been battered by severe rice shortages, soaring prices, and bitter arguments over the release of government stockpiles. With no resolution in sight, public frustration continues to mount. Historically, the drive toward a modern state from the Meiji era onward elevated wet-rice agriculture—long tied to the religious rites of the imperial house—into a nationwide staple. Ever since, swings in rice production have repeatedly triggered deep social unrest.

Between 1590 and 1877, spanning the Edo period and the early Meiji years, some 3,710 peasant uprisings (hyakusho ikki) were recorded, most of them protests against famine and spiking rice prices. But the most explosive rupture came roughly a century ago: the nationwide Rice Riots of 1918. Severe shortages and runaway inflation sparked mass unrest that quickly metastasized into a formidable anti-government movement. Haunted by that precedent, the current administration has scrambled to implement counter-measures, yet none address the underlying cause. As a result, the status of rice has become a flashpoint in the election. Viewed from another angle, however, what we are witnessing may be the first tremors in the collapse of the modern political order built around the rice paddy.

In yesterday’s essay, I touched on the fascinating history of the sweet potato, once known as kansho (甘藷). Wet-rice cultivation was never universal across the Japanese archipelago, and polished white rice was long a luxury largely confined to the ruling classes. The phenomenon of more than one hundred million people eating rice every single day is a creature of very recent history. Yet because the veneration of the rice plant is inextricably bound to imperial rites, the assumption that rice equals the Japanese staple food has been fiercely guarded. Under Meiji State Shinto, national participation in imperial ritual was made compulsory, which inevitably sanctified rice cultivation as a sacred duty. That ideological momentum carried over into postwar Japan, giving rise to an over-protective agricultural regime that ultimately laid the ground for today’s crisis.

Yet, as the accelerating reality of climate breakdown makes clear, rice is increasingly beyond the power of politics to manage. In Niigata Prefecture, the heartland of Japanese rice production, this year’s rainy season brought virtually no rain, followed by an early and blistering heatwave. Drastic drops in yield and severe degradation in grain quality have already been confirmed. These disruptions are nationwide. Whatever promises politicians make during the campaign, they cannot legislate away the forces of nature. The government has floated increasing imports, but that completely misses the point.

The modern system constructed since the Meiji era around the equation of rice and nation is breaking down before our eyes. What we ought to do is return to the lesson of the late Edo period: when catastrophic famines struck, the crop that saved people from mass starvation was the sweet potato. Historically, the majority of Japanese did not live on rice; their sustenance was drawn from millets, taro, and other upland crops. Confronted by unpredictable climate shifts, shifting agricultural policy toward tubers is the most rational safeguard we have. Sweet potatoes and taro thrive across diverse terrains and survive severe weather. For a nation whose food self-sufficiency has collapsed to precarious lows, they could once again become our salvation.

Yet the political establishment remains trapped in the old paradigm, clinging to the imperial myth of a rice-centered diet to preserve the existing order. Japan’s political class is also exceptionally old compared to other democracies. These politicians belong to the postwar generation that consumed more rice than any other in history. They cannot fathom a life without it, convinced that rice is the timeless and eternal staple of the Japanese people. In truth, this dietary monoculture is barely a few decades old, a product of the rapid economic growth of the postwar decades. But politicians who have lived entirely within that brief anomaly cannot see past it. The risk is immense: a catastrophic harvest failure driven by climate shock could instantly plunge the nation into an acute food emergency. Clinging to a rice-dependent food supply is perilous. Reclaiming a diverse culinary culture grounded in millets and root crops is not merely a pragmatic necessity; it could also open new possibilities for Japanese culture itself.

In an already exhausted economy, if ordinary people are cut off from basic sustenance, the possibility of unrest and riots cannot be dismissed. Should current warming patterns swing toward sudden cold shocks, we could easily see famines on the scale of the Edo period. Yet the current government shows not the slightest sign of anticipating such a crisis. Japan has entered an era where citizens must prepare to fend for themselves, in an atmosphere uncannily reminiscent of the late Edo years when the Tokugawa shogunate’s authority began to disintegrate.

To prevent such a calamity, turning back to the ancestral wisdom accumulated through history—and actively cultivating root crops like the sweet potato—is both urgent and pragmatic. Today, thanks to the expansion of cultivation during the Edo period, sweet potatoes are grown even in chilly Hokkaido. Yet production remains heavily concentrated. Kagoshima remains the historical center, while the policies of the eighth shogun Yoshimune Tokugawa, which introduced the crop to the Kanto region as a hedge against famine after the Kyoho disaster of 1732, made Chiba and Ibaraki major producers. Today, those three prefectures alone account for roughly seventy percent of Japan’s total output.

If domestic rice production collapses in the years ahead and tubers must serve as an alternative staple, this geographical concentration will become an acute bottleneck. Regions that quickly divest from rice dependency and begin cultivating tubers in anticipation of modern food shortages will survive; those that do not may find their inaction fatal.

At a moment when political systems across the world are falling into dysfunction, the quiet crisis unfolding around Japanese rice reads as an unmistakable warning of a dark and turbulent future.

What happens when a staple food fails? Takahiro Mitsui argues an order built around rice cracks, and regions that diversify toward tubers will survive — read against the famines of the Edo period.

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.
