Behind every capital stand its fixers

I have touched on Kyoto several times before, but beginning with this essay, I want to open an entryway into understanding Japan's preeminent historic city on a deeper level than ordinary guidebooks offer. It is, in essence, a way to read Kyoto from within.

In Japanese, the word Kyoto literally means the "capital city"—a name originating from the fact that it was once the residence of the emperor. In antiquity, however, wherever the imperial court resided was referred to as kyo, which makes the modern place-name slightly curious. Understanding this also clarifies the origins of Tokyo. When the Meiji government engineered the political relocation of the emperor from Kyoto to Edo in the late nineteenth century, the new leaders balked at retaining the name Edo, loaded as it was with the symbolism of the fallen Tokugawa shogunate. Under the pretext of welcoming the emperor, they renamed the city Tokyo—the "Eastern Capital." In the prewar years, Tokyo was even dubbed the "Imperial Capital" (Teito) to set it apart from Kyoto, a branding maneuver designed to rival the old seat of the court.

The decisive turning point in Kyoto's history arrived in 794, when the imperial palace and the political center of the realm moved into the Kyoto Basin for the first time. Such moves, known as sengu or sento, were far more than administrative relocations; they were driven by the ideological and spiritual anxieties of the people who inhabited that world. Grasping this logic is essential to understanding Kyoto, yet it remains difficult precisely because modern eyes dismiss it as unscientific superstition. Yet this esoteric layer lies at the very frontier of understanding Heian-kyo.

The history of early capital relocations is usually reconstructed from the eighth-century chronicle Nihon Shoki rather than the Kojiki. Because place-names shifted over the centuries, not every site can be identified with certainty, and many remain matters of legend or archaeological debate. Before the court relocated to Kyoto to establish Heian-kyo, however, imperial seats were clustered mainly around the Nara Basin, occasionally shifting into Osaka, southern Shiga, or the southern fringes of Kyoto, but never penetrating what is now central Kyoto. The Kyoto Basin is vast, seemingly as suited for agriculture as the plains of Nara. Why did earlier rulers never venture into it?

The primary reason was Ogura Pond, an immense lake that once covered the southern part of the ancient Kyoto Basin, turning much of the surrounding terrain into waterlogged marsh. Looking at Kyoto today, the central and eastern districts south of the Imperial Palace—where tourists now stroll—were habitable from early times, but the entire western plain was an inhospitable marsh. Since wet-rice agriculture had already become the economic foundation of western Japan, swampy terrain was ill-suited for cultivation, and the area was long left untouched. Then a profound shift transformed the western basin, opening the way for the birth of Kyoto: the arrival of a new immigrant clan.

This group arrived from across the sea. Carrying advanced continental expertise in civil engineering—flood control, irrigation, sericulture, textile weaving, iron weaponry, agricultural implements, and medicine—they entered northern Kyushu via the Korean Peninsula around the late fourth or early fifth century, rapidly fanning eastward across the archipelago. This lineage, known as the Hata clan (秦氏), eventually pushed into the Kyoto Basin. Their first stronghold was Matsuo Taisha, located in the southern part of Arashiyama on the westernmost rim of the basin, an area celebrated today for its bamboo groves. Shrine traditions credit the Hata with founding Matsuo Taisha, but in reality the immigrants entered an area already settled by an indigenous population, enshrining the local spirits while establishing their own headquarters. At the heart of their religious life was a form of monotheism, a subject I will explore another time.

Matsuo Taisha was managed by the Hata clan for centuries until the Meiji era, when government policies abolishing hereditary priesthoods expelled them from the shrine. The Hata based around Matsuo Taisha—on the western side of the basin—formed the main lineage of the clan. Where there is a main house there are branch lineages, and traces show that one branch attempted to push eastward across the basin. Their base became Fushimi Inari Taisha, world-famous today for its corridors of crimson torii gates. This shrine, too, traces its lineage to the Hata.

Yet the geographic relationship between Matsuo Taisha in the west and Fushimi Inari Taisha in the east feels oddly asymmetrical. Fushimi Inari lies not due east of Matsuo, but in a peripheral location far to the southeast. Here lies a fascinating glimpse of pre-Heian Kyoto: the Hata clan attempted to move eastward, but their advance was checked. They were blocked by the indigenous inhabitants who had settled earlier around what is now Shimogamo Shrine, a fertile area blessed with abundant groundwater.

Barred from expanding eastward, the Hata were forced to reclaim the western marshes, deploying their advanced hydraulic engineering to drain and settle the land. Even today, the western part of Kyoto preserves place-names derived from the clan, such as Uzumasa, along with ancient burial mounds. The river flowing near Arashiyama, known in antiquity as the Kadono River, is today called the Oi River upstream near Togetsukyo Bridge and the Katsura River farther down. Plagued by relentless flooding, the river was tamed by the Hata using advanced weir technology, traces of which survive today. This hydraulic engineering was crucial for protecting paddy fields from devastating floods; some scholars have noted its striking resemblance to the ancient weirs built outside Chengdu in Sichuan during the Qin dynasty. While the exact origins of the Hata clan remain shrouded in debate, their chosen character is identical to the Qin dynasty (秦) that first unified China, suggesting a profound continental connection.

Reclaiming the wild terrain of western Kyoto, the Hata simultaneously channeled massive financial contributions and advanced technology—especially weaponry—to the political center in Nara, steadily building ties with the imperial court and amassing immense influence.

Behind the incessant capital relocations that had kept the court wandering across the Nara Basin lay a single terrifying driver: tatari (祟り)—the retributive curse of vengeful spirits. While the imperial house is viewed today as a serene emblem of cultural continuity, its history was fraught with bloody struggles over succession. Along the way, rivals were assassinated, dynasties subverted, and usurpations attempted, each violent act leaving behind deep dread of vengeance from the dead. Tatari is an indispensable key to interpreting ancient Japan; its manifestations ranged from mysterious royal illnesses and political chaos to famine, crop failure, pestilence, sudden climate shifts, and foreign incursions. Neutralizing these curses was a matter of existential survival. In responding to these occult threats, the legendary ascetic En no Ozunu operated in the shadows, establishing an esoteric tradition that would later culminate in the onmyodo master Abe no Seimei, the protector of Heian-kyo.

Amid this cycle of murder and dynastic bloodshed, the appearance of an exceptionally venomous spirit pushed the imperial house to the brink, forcing them to abandon the Nara Basin where they had flourished for centuries and flee in search of a new home. This was the true impetus behind the relocation to Heian-kyo in 794: the court was fleeing for its life from an unbearable curse. In this crisis, it was the Hata clan who stepped forward, offering the court a complete package that included the immense funding required for the move and the magical fortifications needed to ward off the curse, cementing their position as the supreme fixers behind the new capital.

Building on these foundations, the next essay will examine the hidden architecture behind the founding of Heian-kyo.

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 “Behind every capital stand its fixers”, first written on 26 April 2025. Why did Japan keep moving its capital before Kyoto? A capital's quiet fixers fund and fortify it, Takahiro Mitsui shows: the Hata clan gave a court fleeing a curse the money and the magic to move.
