When the guardian of a capital falls

The age of Mount Hiei had come to an end. Ever since the capital moved to Heian-kyo in 794, Mount Hiei had wielded overwhelming hegemony, commanding the hidden machinery that sustained the city from behind the scenes. Standing to the northeast of Heian-kyo in the direction of the demon gate, it assumed the spiritual role of guardian against malevolent forces and became the seat of prayers for the protection of the state, operating in the shadows as the front line against calamity. Its glory eventually reached its zenith as it backed the ruling powers of the court both openly and covertly. From the time Saicho returned from Tang China and founded the monastery in 788, Mount Hiei had existed as one body and one soul with Heian-kyo; if either collapsed, everything would end. Yet by the late twelfth century, four centuries after its founding, the religious prestige that had once radiated from the mountain had fallen into ruin. Its spiritual power spent, Mount Hiei left everyone who looked upon it disillusioned. At that moment, as the communal illusion that had long sustained Mount Hiei's dominance dissolved, the possibility of a new religion began to take root.

What deserves particular attention is that the great tide of faith seeking a way beyond Mount Hiei did not emerge from outside that communal illusion, but from within it. Unless we grasp the course of events that led to this point, we cannot understand the new religious movement that was about to begin—which is why, throughout this series, I have traced the conditions of the era from my own vantage point. All of it came to a head when six years of fierce civil war broke out between 1180 and 1185, bringing Heian-kyo to its end and resetting everything. Even so, it is a constant of history that the signs of collapse in a long-standing regime always appear slightly before the decisive event itself. Just yesterday in Japan, a snap general election was held, and amid the structure of entrenched interests and the voting dynamics of a super-aged society, the Liberal Democratic Party cemented its single-party dominance in a result that carries on the second Abe administration. Surveying the final years of the Heian period like this makes it self-evident that in structure, nothing has changed.

In the span of a single human life, it is perhaps only natural to wish for a lifetime free of upheaval and to hope to live out one's days in peace. Yet because every system inevitably rots, it is equally true that unless everything is periodically reset, no light can break through. As someone who loves to look deeply into history, I cannot help feeling that an ending is not something to mourn, but a hope for the future. What must end always ends; that is the way of the world. Put another way, what must end must be brought to an end. The rise and fall of the Taira clan under Taira no Kiyomori, which we have followed up to this point, was eventually handed down as The Tale of the Heike, and the impermanence of that prosperity still pierces the heart today. For me, the reflections in this series serve as a kind of reverse image tracing the contours of present-day Japan.

The signal fire announcing the end of Heian-kyo erupted as a military clash between the Taira and the Minamoto, concluding when Minamoto no Yoritomo seized supremacy for the Minamoto and declared victory in Heian-kyo. Yet because western Japan, centered on Heian-kyo, harbored many hostile forces tied to Taira remnants, and because Heian-kyo itself had already outlived its historical role, Yoritomo decided to grasp the real reins of power by opening a shogunate—a bakufu—far to the east in Kamakura, in present-day Kanagawa Prefecture. The bakufu was born for the first time in this era. Almost without exception, the political system of Heian-kyo had been carried on by emperors and nobles within the old framework of the imperial court. The newly risen warrior class, however, sought to keep its distance from those old powers and govern on its own terms, and so established an entirely new system.

In Japanese, bakufu (幕府) is written with the characters for "curtain" and "government office." The word derives from China, where it referred to the headquarters or office—fu (府)—inside the field curtain—baku (幕)—from which a general directed operations. A bakufu, in other words, was the political system best suited to a military leader, and this leader was tied to the official title of Sei-i Taishogun, appointed by the emperor. The office of Sei-i Taishogun had existed since the Heian period, originally conferred upon the commander of military expeditions sent to subjugate peoples living east of Heian-kyo who refused to submit to the court. Because the authority it carried was vast, and making it permanent could have posed a threat to the court itself, the title had historically been granted only on a temporary basis when such campaigns were needed. Once Minamoto no Yoritomo seized hegemony, however, he legitimized this office and repurposed it for a new political order in which he reigned as supreme leader of the bakufu. From then on, Sei-i Taishogun became synonymous with the head of the bakufu. It became customary for the imperial court to appoint the Sei-i Taishogun, though this was purely a formality meant to secure the legitimacy of the bakufu leader's authority as one appointed by the emperor.

In 1175, just before the upheaval that would establish the Kamakura bakufu, a man appeared who made a momentous decision, convinced that if he remained on Mount Hiei he would be able to save neither himself nor anyone else. That man was Honen (1133–1212). Honen is thought to have begun his training at Enryaku-ji on Mount Hiei around the age of fifteen, but by around eighteen he had already sensed the limits of Enryaku-ji and withdrawn into seclusion. He did not leave Mount Hiei altogether; instead, he moved to Kurodani Bessho, a quiet mountain retreat on Mount Hiei about a kilometer and a half north of Enryaku-ji. It was a hidden sanctuary for monks practicing in reclusion—if Enryaku-ji was the mountain's public face, this was its hidden side. Here the young Honen continued his training under a master named Eiku. Because Honen remained untouched by the political currents of main Enryaku-ji during this turbulent period, he was able to stand back and read the age with clear eyes. Though the distinction can be confusing, Kurodani Bessho, like Enryaku-ji, belonged to the Tendai school.

For years, however, Honen had keenly felt that the rigorous training of the Tendai school had already hollowed out into mere form, and that the monks of Enryaku-ji had abandoned the way of the Buddha, giving their days over to juvenile debates and politics with no power to save the people living down in the city of Heian-kyo. Even as these problems grew acute, so long as he remained a monk under the wing of Mount Hiei, reclusive or not, he had no way forward other than to shut himself away in the mountains and practice. Yet the world centered on Heian-kyo that we have been surveying had already entered the age of ruin that Buddhism calls the Latter Days of the Dharma.

"Can I really go on like this?" Anyone who seeks to live in truth must pass through that question, and Honen faced it day after day deep in the mountains of Mount Hiei. No matter how earnestly he confronted himself and devoted himself to practice, keeping away from monks who lived in dissipation, no path forward came into view. In a desperate situation where he could only conclude that Tendai had no future, Honen turned to books for an answer. It is true that meeting a good teacher can determine the course of a life, yet in some eras such an encounter is simply not to be had. For Honen, who had entered seclusion so young, the answer could only be found in the books left behind by those who came before him.

Honen threw himself into reading, so much so that he is said to have read through the vast collection of Buddhist scriptures housed at Kurodani Bessho three to five times over. Yet no matter how many books one reads, without grasping the truth it is nothing more than a waste of time. By 1175, at the age of forty-three, Honen had given everything to the practice of attaining Buddhahood ever since drawing praise for entering seclusion at the young age of eighteen; yet he was beginning to understand that however long he pursued his own practice, he could never reach awakening while ignoring the suffering people of the world. At that moment, a sense of mission unlike anything he had ever known began to stir within him. With his consciousness transformed, he picked up a book he must have read many times before as if reborn, and his fate was sealed. He was struck by a passage in an old book brought from China: the Commentary on the Contemplation Sutra, written in the seventh century by Shandao (613–681).

There he found the following exposition: 一心専念弥陀名号 行住座臥不問時節久近 念念不捨者 是名正定之業 順彼仏願故. In modern terms: "Single-mindedly recite the name of Amida Buddha alone. Whether walking, standing, sitting, or lying down, without asking whether the time is long or short, continue reciting the nenbutsu without ever letting it go from moment to moment. This is the act that truly settles birth in the Pure Land, because it accords with that Buddha's Original Vow." In Buddhism up to that time, the mainstream of nenbutsu (念仏) had been kanso (観想), an advanced practice of visualizing the form and virtues of the Buddha in the mind, whereas shomyo nenbutsu (称名念仏)—calling out "Namu Amida Butsu" with the voice—tended to be regarded as inferior or merely supplementary. This was a feature not limited to Japanese Buddhism, and precisely because of it, monks had to attain that high state through rigorous learning and austere training.

In a sense, this very feature lay at the root of the privileged status monks held in the Heian period. The moment Honen saw this passage, he realized that the Buddhist attitude centered on kanso—the source from which temples had long turned monks into a privileged class—would never save ordinary people, and he awakened to the thought that the true teaching of the Buddha must be one that anyone can put into practice. What was wrong, he understood then, was the high-handed attitude of monks who arbitrarily decided for themselves that common people could never reach the realm of the Buddha. Needless to say, harsh ascetic training was limited to elite monks and was not open to all. Seeing the limits of that closed world, Honen found in Shandao's teaching a way that could be practiced not only by elite monks, but even by a starving, suffering old woman among the common folk of Heian-kyo. That way was shomyo nenbutsu, the practice of reciting the nenbutsu aloud.

Broadly speaking, what Honen awakened to was this: a practicable way open to all is the very truth of Amida Buddha, who wished to save all people equally; and because that salvation is accomplished by Amida Buddha's power, deliverance for human beings lies not in their own strength, but in riding upon Amida Buddha's vow.

This way of thinking rests on the Eighteenth Vow among the forty-eight vows—the Original Vow, or hongan (本願)—that Amida Buddha made while still in training as the bodhisattva Dharmakara. It reads: "When I become a Buddha, if the people of all worlds believe in me with all their hearts and call my name even ten times, I will without fail cause them to be born in my land. If I cannot fulfill this, I shall never become a Buddha." Here, the name of Amida Buddha means "Namu Amida Butsu," and Amida Buddha's land means the Pure Land of Utmost Bliss. Honen reasoned, in other words, that since all preparations for salvation had already been completed on Amida Buddha's side, human beings had no need to struggle and agonize in search of effort or talent; they needed only to board the ship that Amida Buddha had already built for them.

Reinterpreting the teaching to mean that people living in this world need only keep reciting Amida Buddha's name, "Namu Amida Butsu," Honen grasped this as the sole truth capable of saving the countless people who despaired in a world that could well be called hell, and he established this way of entrusting everything to Amida Buddha as tariki hongan (他力本願)—salvation through the Other-Power of the Original Vow. The idea that Amida Buddha would unfailingly carry any wicked or ordinary person to the Pure Land simply for calling his name answered completely to the reality of the people of Heian-kyo. Having reached this awakening, Honen resolved that his mission was not to remain in seclusion until the end of his life, but to live in order to save the people of Heian-kyo. Counting from the age of eighteen, after spending some twenty-five years in reclusion, he decided to give up seclusion itself and step out onto the public stage. In the world of Japanese Buddhism, this made him an extraordinary kind of monk.

Around 1175, at the age of forty-three, Honen left Kurodani on Mount Hiei, where he had spent so many years, walked into the city of Heian-kyo, and before long chose Yoshimizu in Kyoto's Higashiyama district as his new base. Today the area is crowded with visitors as home to Maruyama Park and Chion-in, two of Kyoto's major sightseeing spots, but historically it was no place where the common folk of Heian-kyo would set foot. Because the world at the time was in the midst of ruin, recluses disillusioned with life inside Heian-kyo had built grass huts around there, yet historically it was an otherworldly realm for burying the dead, a place neither commoners nor nobles of Heian-kyo entered. Here Honen built a simple grass hermitage and threw himself into his work on the basis of his awakening. That was the beginning of the Jodo school in Japan.

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 “When the guardian of a capital falls”, first written on 9 February 2026. Why did new Buddhism come from Mount Hiei? When an institution loses its prestige, Takahiro Mitsui writes, a seeker like Honen leaves for the margins, here Mount Hiei after four centuries — why the next faith rose from inside Mount Hiei.

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: “Dissolution is not loss but a way of seeing things as they are, by dissolving the split between subject and object.” (Project 2049 Vol.0, https://project-2049.takahiromitsui.com/vol-0 )
