A little over five hundred years ago, fleeing the flames of a great war that burned the capital, a single high-ranking court noble came down to this far-distant western land of Tosa. Longing for the capital, this noble built, by the river of this land, a grid town in imitation of the capital, and transplanted here place-names likened to the capital. In time this noble’s house became feudal lords in this land, and the town prospered as their castle town. This town that copied the capital is still called "the little Kyoto of Tosa." And in this same town flows a great river, also called the last clear stream. This town that was a town copying the capital has widened its city area through a merger. Shimanto’s numbers are the record of a town engraved by the history of the little Kyoto and the great river.
A city that opens on the lower reaches of the Shimanto River in the west of Kochi Prefecture. To read the population, one must take the merger into account. In 2005 the city on the river’s lower reaches and the village upstream merged anew to become the present Shimanto City. The population in 2005, after the merger, was 37,917, and from there it has fallen to 32,694 in 2020. What I (Atlas) want to read here is not the sign "little Kyoto" itself, but the causal thread: how the history — a town that copied the capital and a great river — is translated into today’s population and finances.
01 · Seeing the present Shimanto in its numbers
In the latest Population Census the population is about thirty-three thousand (32,694 in 2020). This city was born in 2005 when the city on the lower reaches of the Shimanto River and the village upstream merged anew. The population in 2005, after the merger, was 37,917, and from there it fell gently — 35,933 in 2010, 34,313 in 2015, 32,694 in 2020. The numbers in this article are those of the city area formed by this new merger.
Looking inside, the figure of a regional town that opened on a river’s lower reaches shrinking appears. The share aged 65 and over rose from 27.0% in 2005 to 36.8% in 2020, nearing four in ten. The household-with-children share was 17.1% (2020), and the Childcare Waitlist was zero in both 2024 and 2025. The Fiscal Capacity Index was 0.34 in fiscal 2023 — it can cover only about three-tenths of expenditure with its own tax revenue, with a large reliance on the allocation tax. The figure of a town that was a town copying the capital, losing population while deepening aging, appears in the numbers. Why it takes this shape cannot be read without going back over the history of the little Kyoto and the great river.

02 · A court noble fleeing the capital’s wars, a capital copied by the river, the great river of the last clear stream — the history behind the numbers
This town’s skeleton is set by the capital that a court noble, fleeing the capital’s wars, copied by the river here, and by the great river that runs through that town. The old layer is the noble and the town. At the close of the Muromachi era, fleeing the flames of a great war that burned the capital, a single high-ranking court noble came down to this far-distant western land of Tosa. Longing for the capital, this noble built a residence by the river of this land, made a grid town in imitation of the capital, and transplanted to this land place-names likened to the capital’s rivers and mountains. In time this noble’s house became the feudal lords governing the west of Tosa, and the town prospered as their castle town. The grid town layout copying the capital, place-names tied to the capital, related shrines and the like still remain in this land, and the town is called "the little Kyoto of Tosa."
Another foundation of this town is the river. The great river that runs through this land and pours into the Pacific holds no large dam in its basin and is also called the last clear stream. Bridges over the river, with their railings removed so as to sink under the water when it rises, and boats going down the river have shaped this land’s scenery. The road by which it became a city mirrors this town too. In 2005 the city on the river’s lower reaches and the village upstream merged anew, and this city was born. A court noble fleeing the capital’s wars and a capital copied by the river, and the great river of the last clear stream. The position of the lower reaches of the Shimanto River has held these two histories and shaped the present form of the city.

03 · In a town that was a town copying the capital, losing population
What characterizes Shimanto is that, while holding the history of a town that copied the capital and a great river, it loses population and deepens aging. From the 37,917 of 2005, after the merger, to the 32,694 of 2020, about five thousand fell over fifteen years. This land, opening on the lower reaches of the Shimanto River, lies in the west of Kochi Prefecture, far even from the prefecture’s central city, and finds it hard to draw in new workplaces widely. A life supported by the blessings of farming, forestry, river and sea has continued, but one can read that, as the young generation moved to urban areas in search of work, the population has fallen. That the share aged 65 and over neared four in ten at 36.8% in 2020 is also an expression of that population makeup.
On the other hand, the Childcare Waitlist was zero in both 2024 and 2025. A Fiscal Capacity Index of 0.34 is a level able to cover only about three-tenths of expenditure with its own tax revenue, with a large reliance on the allocation tax. It mirrors that, as a regional town opening on a river’s lower reaches, the limits on its own tax base are real. The population falls, aging nears four in ten, and the fiscal strength is weak. But laying these three out separately does not bind up the figure of a town on the lower Shimanto. A falling population, deepening aging, and a thin tax base proceed at once upon the history of a town that copied the capital — only laid over one another in this way does this town’s present come into view.

04 · A court noble who avoided the capital copied the capital by a river — the starting point
The present Shimanto has several functions of differing history folded in. One is the old layer in which a court noble who came down fleeing the great war that burned the capital made, by the river, a grid town in imitation of the capital and transplanted place-names likened to the capital, whose town layout and place-names still remain and which is called "the little Kyoto of Tosa." Another is the position where a great river, holding no large dam and also called the last clear stream, runs through the town, where bridges that sink under the water when it rises, and boats, shape the scenery. The position of the lower reaches drew in the court noble who avoided the capital and raised the town by the river.
In the west of Tosa, far from the capital, a great river pours into the Pacific — that geography became the destination of a court noble avoiding the capital, called in the town by the river, raised a castle town, and through a merger connected to the present city area. What is unexpected is that this town’s beginning was "inconvenience." The very distance that once kept the capital away and drew the noble in turns, in the modern era, into a condition that makes it hard to draw people. The same distance has, over five hundred years, exchanged its welcoming face and its releasing face.

05 · Atlas’s note — a town whose beginning was its weakness; the distance from the capital called the noble in
Lay out Shimanto’s numbers and the indicators of a regional town that opened on a river’s lower reaches shrinking line up: a post-merger fall of population, an aging rate of 36.8%, a household-with-children share of 17.1%, and a fiscal capacity of 0.34. But with the eye of one who has handled numbers as a certified public accountant, what I want to note first is that this city was born in 2005 when the city on the lower reaches of the Shimanto River and the village upstream merged anew. The numbers in this article are those of the city area formed by this merger, and need to be read apart from the separate courses each walked before the merger — the lower-reaches city and the upstream village.
Upon that, what I want to read is that this town’s starting point lay in that very position of being "far from the capital." A little over five hundred years ago, that a high-ranking court noble came down to this land fleeing the flames of a great war that burned the capital was because this was far from the capital and a land the flames hardly reached. The position of being far from the capital drew in the noble who longed for the capital and gave rise to a town that copied the capital by the river. But that same position of being "far from the capital," from the modern into the present era, appears in the town as a fall of population, as a condition that makes it hard to draw in new industry or population. The position that once drew the noble in is now a condition that loses population — the thread by which the same geography holds opposite meanings depending on the age. On the other hand, because of that very distance, the town still keeps the old layout and place-names copying the capital, and the river keeps a clear stream holding no large dam. How the town connects this history to its life and its visitors while losing population is a question proper to the town on the lower Shimanto. Whether to read it as the sign "little Kyoto" and pass over it, or to see it as "a town where a court noble fleeing the capital’s wars copied the capital by a river," changes with the reader’s way of living. This town’s numbers begin not from the convenience of nearness to the capital but from the inconvenience of being farthest from the capital. Trace the root of the falling population, and one arrives at the same distance that called the noble in five hundred years ago — a rare town whose beginning was its weakness.
