The silk weaving of this land goes back to the records of the Nara era and is also named on the world’s list of intangible cultural heritage. A land that produced silk from antiquity became, in the medieval period, the castle town of a renowned house, and has carried its tsumugi down to the present. The castle town of tsumugi, while nearly holding its population, declines gently. Yuki-shi’s numbers are the record of a town inscribed with a history of silk and a castle town stretching over a thousand years.
A city at the western edge of Ibaraki Prefecture, opening out with the Kinu River as the prefectural border. The population has fallen gently within a near-flat band, from 52,774 in 2000, through 52,494 in 2010, to 50,645 in 2020. What I (Atlas) want to read here is not the sign “the home of tsumugi,” but the causal thread: how the history — silk of antiquity, the castle town of the Yuki clan, and the intangible cultural heritage — is translated into today’s population and finances.
01 · See the Yuki-shi of today in its numbers
In the latest Population Census the population is about fifty-one thousand (50,645 in 2020). Its transition is a gentle decline within a near-flat band. From 52,774 in 2000, through 52,460 in 2005, 52,494 in 2010 and 51,594 in 2015, to 50,645 in 2020, it fell by about two thousand over twenty years. It is the curve of a town that has slowly shrunk without large rises or falls.
Looking inside the figures, the figure proper to a small-to-mid city of the northern Kanto appears. The share aged 65 and over rose from 17.4% (2000) to 30.4% (2020), passing three in ten. The household-with-children share, at 22.0% in 2020, is comparatively high, and the Childcare Waitlist was zero in both 2024 and 2025. The Fiscal Capacity Index was 0.69 in fiscal 2023 — a level whose own tax revenue covers about seven-tenths of expenditure, comparatively high for a small-to-mid city. The castle town of tsumugi deepens in age while nearly holding its population, and keeps its fiscal stamina comparatively high. Why it has been able to hold them does not come into view without going back over the history of silk and the castle town.

02 · Silk of antiquity, the castle town of the Yuki clan, the world’s intangible cultural heritage — the history behind the numbers
Yuki’s skeleton is set by this land that produced silk from old, and the castle precinct of a renowned house that governed here in the medieval period. The old layer is silk. This land has been known from old as a producer of hemp and silk, and its silk weaving is said to go back to the records of the Nara era. The place name “Yuki” too is handed down as deriving from its having been a producer of hemp and silk. The silk weaving rooted in the land set this town’s oldest foundation.
And in the medieval period, this land became a castle town. In the Kamakura era a clan branching from a powerful warrior house built a residence on this land, and thereafter this land became the castle town of the Yuki clan, which continued as a renowned house since Kamakura. Under the castle precinct, the silk weaving grew further. From around the Keicho years (1596–1615), the silk weaving of this land came to be called “Yuki-tsumugi,” and at the beginning of the Edo era a considerable volume is said to have been produced. This tsumugi, with a distinctive texture of handwork, was inscribed in 2010 on the world’s representative list of intangible cultural heritage. The silk from antiquity, the castle town raised it, and it was carried down to the present as a tsumugi recognized by the world. The strength of this land, which produced silk from old on the bank of the Kinu River, called the castle town and raised the tsumugi.

03 · In the castle town of tsumugi, it nearly holds its population while deepening in age
What characterizes Yuki-shi is that, while holding a history of silk and a castle town stretching over a thousand years, it declines gently while nearly holding its population and deepens in age. From 52,774 in 2000 to 50,645 in 2020, it fell by only about two thousand over twenty years. Without the advance of large factories or a steep increase from new residential development, the urban functions as a castle town and the industry rooted in the land can be read as having held the population without a large collapse. That the share aged 65 and over passed three in ten at 30.4% in 2020 is an expression of how, within a gentle decline, the generations that live here have grown older together.
On the other hand, the household-with-children share, at 22.0% in 2020, is comparatively high, and the Childcare Waitlist was zero in both 2024 and 2025. The settled residential environment of a castle town can be read as having held households with children to a degree. A Fiscal Capacity Index of 0.69 is a level covering about seven-tenths of expenditure with its own tax revenue, comparatively high for a small-to-mid city. The castle town of tsumugi now deepens in age while nearly holding its population, and keeps its fiscal stamina comparatively high. A near-flat population, aging passing three in ten, comparatively high finances — this gait of a northern-Kanto town holding an industry rooted in the land cannot be explained by any single number alone. Only where the three support one another does the town’s outline come into view.

04 · A history of silk and a castle town stretching over a thousand years, overlapping in one land
In Yuki several faces silk brought overlap. One is the history of the silk weaving that goes back to the records of the Nara era and gave rise to the place name, carrying the old layer of an industry rooted in the land. Another is the character of the castle town of the Yuki clan, which continued as a renowned house since Kamakura, keeping the history of raising tsumugi under the castle precinct. And the Yuki-tsumugi, inscribed in 2010 on the world’s intangible cultural heritage, gives this town the singular structure of carrying handwoven textile down to the present.
From a producer of silk of antiquity, to the castle town of the Yuki clan, and on to a town that carries down a tsumugi recognized by the world. The strength of this land, which produced silk from old on the bank of the Kinu River, called the castle town and raised the tsumugi. Storehouse-style shopfronts still remain on the castle-town streets, and somewhere deep within one of them a loom of handwork going back to the Nara era weaves in the threads one by one — at the western edge of the prefecture, a thousand years of silk still continues.

05 · Atlas note — what to ask now of the silk that has continued for a thousand years
Lay out Yuki’s numbers and the indicators of a small-to-mid city of the northern Kanto line up: a near-flat population, an aging rate of 30.4%, a household-with-children share of 22.0%, fiscal capacity of 0.69. But turning my eyes to the relation between number and number, what I (Atlas) want to read is the tie between the population being held nearly flat and the fiscal capacity being comparatively high for a small-to-mid city. To stay, without relying on large factories or new residential land, at a decline of about two thousand over twenty years and to keep a fiscal capacity of 0.69 can be read as the industry rooted in the land and the urban functions as a castle town supporting the town’s footing thickly. Industry rooted in the land does not, like a factory that moves by a firm’s decision, suddenly leave this land.
One more thing to consider is that this town still holds “silk stretching over a thousand years,” an extremely old industry. The silk going back to the Nara era grew as tsumugi under the castle precinct and was inscribed in 2010 on the world’s intangible cultural heritage. An industry that continues this long is rooted deeply in the land and in human skill. On the other hand, the number of people who bear the handwoven textile shifts with the times. How a town holding an old industry hands its bearers on to the next generation is a task not limited to the castle town of tsumugi. For this town, which has stayed at a decline of about two thousand over twenty years without relying on factories or new residential land and kept a fiscal capacity of 0.69, the real question may be neither population nor finance. The handwoven textile that goes back to the Nara era, grew under the castle precinct and is named among the world’s intangible cultural heritage — how to hand its bearers on to the next generation. Industry rooted in the land does not suddenly leave as a factory does, but the number of those who weave shifts with the times. Whether the silk that has continued for a thousand years will go on unbroken from here — that course lies, as a task still without an answer, before each person who would tie a bond with the town called Yuki.
