To leave the old order is how an age begins

The possibility of a great upheaval in Japan rises year by year, and since history repeats, we can make a rough guess at what will move in the next social change. So this time, anticipating that change, I turn to the movements around the end of the Edo period, when the old order gave way to a new one. The key term of that change is "dappan," leaving one's domain. By looking at its meaning for today, we can recognize the signs of a transformation that has already begun. In perhaps twenty years, its seeds will change Japan greatly.

In the Edo period the Tokugawa shogunate sat in Edo (now Tokyo), but it was hardly a strong centralized structure. Rather, the domains scattered across the land held the power, and a system in which they supported the shogunate was maintained. As I have shown several times in Shitsurae, Neo-Confucianism was adopted as the philosophy of the Edo order and Japanized, and under it, from the standpoint of absolute loyalty to the domain lord, a samurai basically had no choice but to serve his domain for life.

Throughout the Edo period the shogunate is said to have treated dappan, leaving one's domain without permission, as a grave crime punishable by death. Toward the later part of the period, though, the spirit to throw off dependence on the old order and make a new age with their own hands rose among the young. This movement of dappan led in the end to the Meiji Restoration of 1868, which brought down the shogunate. The collapse of a firm old order, and the founding of a new age by young people with new ideals, may well be a factor in Japan's future too.

Though dappan was a grave crime, in the final years of the shogunate young men one after another broke the prohibition to hold to their own purpose, and acted beyond the frame of the social order. The creed they held then was "to choose a great cause over the domain." As society shook, lower-ranking samurai felt that merely serving the shogunate or the daimyo who governed the domains could not meet the new national crisis, and gradually became masterless men who left their domains and ran about the country. What deserves attention is that the core of these movements was lower-ranking samurai.

The main current of the time was that anti-shogunate forces rose, led by the Choshu domain (now Yamaguchi Prefecture), and many samurai with antiestablishment ideas flowed into the Kyoto-Osaka area. The shogunate called them "ronin" and "vagrants" and grew wary. But the shogunate was already in effect failing to govern, with no realistic measure to deal with them, and the upper-ranking samurai who clung to the old order could do nothing. The young samurai who had left their domains moved around the country, built a decentralized network of their own, and began to act, slipping past the regime's watch. This network became the driving force that spread particular ideologies, and it played the important role of linking domains that tended to be at odds.

They were only lower-ranking samurai, and however many gathered, they could not stand against the mighty shogunate. So some of the men who had left their domains thought of overthrowing the shogunate in one stroke by allying strong domains that were geographically far from Edo and held anti-shogunate ideology. The central figure was Sakamoto Ryoma (1836-1867).

Among the dappan men of the late Edo period, Ryoma remains a symbolic figure, still popular with the Japanese. He was a lower-ranking samurai of the Tosa domain (now Kochi Prefecture) and left Tosa in 1862. Shortly before, he had met Kusaka Genzui (1840-1864) of Choshu and was drawn to an idea Kusaka put forward. It is called "somo kukki," the rising of the grass: neither the lords nor the court nobles can be relied on, but if people with grassroots resolve gather, they can move the realm. Greatly moved by Kusaka, a man of his own generation, Ryoma felt the limits of an anti-shogunate movement that depends on the domain, and left it to seek solidarity among those who shared a purpose for Japan's future.

After leaving, Ryoma kept in touch with men of purpose in the various domains, such as Saigo Takamori (1828-1877) of Satsuma and Kido Takayoshi (1833-1877) of Choshu, and worked energetically, later brokering the Satsuma-Choshu alliance and conceiving the founding of a new government. Even now Ryoma is called "the superhero who flew freely between domains and achieved the Meiji Restoration." He is indeed a man who opened the door to a new age by his own intuition and vision of the future. He was assassinated in Kyoto in December 1867, just before the turbulent Restoration succeeded, and never saw the Japan to come.

It is known that many other heroes of the Restoration were also men who had left their domains, but how large the scale of dappan actually was remains unclear. Recent research even suggests that dappan was already commonplace in the later Edo period, so it is hard to grasp the reality.

Ryoma of Tosa, and his comrade Nakaoka Shintaro (1838-1867), are credited with using their position as ronin who had left Tosa to broker between Satsuma and Choshu and to help create the Satsuma-Choshu alliance (1866). They were, so to speak, "samurai with no affiliation." However fine the ideals a samurai of the Edo period held for the future, Neo-Confucian education left him unable to throw off absolute loyalty to the shogunate or his domain, so he had to give up living for those ideals. Breaking that loyalty was thought to defile the ideal image of the samurai. For lower-ranking samurai, who had begun to fall into want, the ideal was less a good than the embodiment of an ideology that deserved to collapse.

So they gave up belonging and began to move freely, with no affiliation. Seen differently, this meant leaving a rigid social order, and being released from the rules tied to it. To throw oneself into such a position, all one needs is a belief in Japan's future that never wavers. Whether one can hold that belief to the end: I take the true enemy to have been neither shogunate nor domain, but always oneself. So I rate highly the men who held to that one point, though it is plain it was not the general tendency. In fact, the Choshu system that became the axis of the new order looks in many respects as if it simply used the movements of the dappan men to take the seat of Tokugawa authority. How far it can really be called a "new order" remains an open question.

The structure of rule set up after the Restoration kept its authority for so long that the Meiji Restoration has been idealized. No one knows the true reality. But if something like the end of the Edo period happens again, what will collapse next is that structure. How, then, should we see the present counterpart of the men who once left their domains?

The first keyword is the Japanese who is "unaffiliated" and can move. The conditions differ from that age in countless ways. In Japan, which has entered the first super-aged society in the world, the elderly are an overwhelming majority, and a social rigidity that is conservative and does not accept new ideals is firmly held. This differs greatly from the United States, where generations are turning over. Since Japan is an environment in which social change is slow to arise, we will keep waiting and preparing for about twenty years.

The other keyword is the "ideal for the future of Japan and the Japanese." However unaffiliated and mobile one is, merely moving abroad is meaningless. Going abroad is not itself a power. Unless people appear who know Japan deeply and care from the heart about the future of Japan and the Japanese, there is no force to change society. The modern men who leave their domains are those who deeply understand the Japanese context and carry ideals and a vision for the future.

The numbers will inevitably be few. But the last age too began with a few, so there is no need for pessimism. Japan's social change in particular will be postponed unless a huge earthquake strikes the cities, so we must assume at least twenty years. Around 2045, I expect, the change that decides the next age will come. I will be in my mid-fifties then, and I am exploring the possibilities day by day with that in mind.

At present I am involved only with the few who meet all these conditions and hold a strong ideal for the future of Japan and the Japanese. They do not belong to the solid Japanese society that corresponds to the old shogunate, or belong only in part while moving about, so they are spared social pressure. The Japanese of today do not know they exist. I take them to be the force that will later create a great movement. I disclose to them all that I know of Japan, and at times we travel together and share our convictions.

To renew the present order, we cannot avoid looking again at three structures rooted in postwar Japanese society: the yakuza, the new religions, and the security framework around the US forces in Japan. I will write on these intertwined relations separately. The yakuza and the new religions are already shaking greatly, so what remains last is the security framework.

By 2045, twenty years from now, can Japan rebuild by its own hand how it keeps the country safe? That will be the factor that decides the next Japan, and it will greatly affect the generations to come.

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: “What people take to be their true self is entirely kago, the provisional self they have taken on from childhood until now.” (Project 2049 Vol.1, https://project-2049.takahiromitsui.com/vol-1 )
