This town is on a Musashino plateau where several rivers meet. The river flowing out from the mountains pours into another river right around this town. In old times it was a hamlet where people and goods gathered with a standing market, and the shrine that hands down a kagura was revered as the chief tutelary shrine bundling the twelve districts of northern Musashi. This plateau where rivers meet, once a private railway heading for the city center ran through and it became a town where a university was placed, increased its population, and now holds that number at a high level. Sakado-shi’s numbers are the record of a town inscribed with the history of the market post of the plateau where three rivers meet.
A city in the central part of Saitama Prefecture, opening on the Iruma plateau of Musashino where several rivers meet. The population, after rising from 97,381 in 2000 to 101,700 in 2010, moved to 100,275 in 2020, holding roughly flat at the high level of about one hundred thousand. What I (Atlas) want to read here is not the sign “a residential area near the city center,” but the causal thread: how the history of the market post of the plateau where rivers meet is translated into today’s population and finances.
01 · Looking at the Sakado-shi of today in its numbers
In the latest Population Census the population is about 100,000 (100,275 in 2020). Its course is a form that rises and then holds flat at a high level. From 97,381 in 2000, through 98,964 in 2005 and 101,700 in 2010, it passed one hundred thousand, and through 101,679 in 2015 to 100,275 in 2020, it has held roughly the level of one hundred thousand.
Looking inside, the figure of a residential area matured on the plateau appears. The share aged 65 and over rose by about eighteen points over twenty years, from 11.2% in 2000 to 29.4% in 2020, nearing three in ten. The household-with-children share is 18.6% in 2020, and the Childcare Waitlist was zero in both 2024 and 2025. The Fiscal Capacity Index was 0.78 in fiscal 2023, a level above the middle covering nearly eight-tenths of expenditure with its own tax revenue. The market post of the plateau where rivers meet, holding its population at a high level after gaining the private railway while advancing its aging, appears in the numbers. Why it took this form cannot be read without going back over the history of the rivers, the market, and the private railway.

02 · The plateau where rivers meet, the market hamlet and the kagura shrine, the chief tutelary shrine of northern Musashi, the private railway through the plateau — the history behind the numbers
This town’s skeleton is set by the landform of the plateau where rivers meet, the market hamlet that stood on that plateau, and the private railway that ran through the plateau. The opening layer is the landform. This town is on the Iruma plateau of Musashino, and the river flowing out from the mountains pours into another river right around this town. The plateau where rivers meet was a land where water was easy to obtain and people and goods readily gathered. The name of the river flowing along the edge of this plateau is said to derive, in the distant past, from the name of an old district established to bundle the people who had migrated to the land of Musashi from across the sea, whose district area centered around the neighboring city of today.
On this plateau where rivers meet, a market hamlet stood from old times. In this land where people and goods gathered was a shrine that hands down a kagura, and that shrine was revered as the chief tutelary shrine bundling the twelve districts of northern Musashi. The kagura handed down at the shrine is listed, as one preserving an old form of the Edo sato-kagura, among the intangible cultural properties the nation has selected. The market hamlet and the kagura shrine were at the center of the plateau where rivers meet. On this plateau, the modern private railway was layered. Once a private railway heading for the city center ran north–south through the plateau, this town became a town where people commuting to the city center by that railway live, and a university was placed within the city. The plateau where rivers meet, the market hamlet and the kagura shrine, the chief tutelary shrine of northern Musashi, and the private railway through the plateau — this town’s form stands upon the history of the market hamlet and the kagura that the Musashino plateau where rivers meet held.

03 · On the plateau where rivers meet, holding its population at a high level while the aging advances
What characterizes Sakado-shi is that, while bearing the old history of a market hamlet and a kagura shrine, it holds its population at a high level and advances its aging. After rising from 97,381 in 2000 to 101,700 in 2010, it has held roughly the level of one hundred thousand to 100,275 in 2020. Behind this town holding one hundred thousand while many regional cities lose population, one can read that, easy to commute to the city center by the private railway, housing and a university spread on the plateau.
On the other hand, the share aged 65 and over neared three in ten at 29.4% in 2020, up by about eighteen points over twenty years. It can be read as the expression of the households that moved in during the period when the private railway ran through and increased the population now aging together. The Childcare Waitlist was zero in both 2024 and 2025, and the household-with-children share is 18.6% in 2020. A Fiscal Capacity Index of 0.78 is a level above the middle covering nearly eight-tenths of expenditure with its own tax revenue. The income of the many households commuting to the city center can be read as supporting the tax source above the middle. The population holds one hundred thousand, the aging nears three in ten, and the fiscal stamina is above the middle. Look only at the total and it seems an unmoving town, but inside it, the generation that entered all at once by the private railway keeps quietly raising its age.

04 · The meeting point of rivers called in the market and the kagura
Sakado, as a town opened on the Musashino plateau where rivers meet, holds several functions of its own. One is its history of being on a plateau where the river flowing out from the mountains pours into another river, a market hamlet where people and goods gathered. Another is its character of holding a kagura shrine that preserves an old form of the Edo sato-kagura, that shrine revered as the chief tutelary shrine bundling the twelve districts of northern Musashi. The plateau where rivers meet called in the market hamlet, and the private railway and university heading for the city center.
Sakado is a town where the plateau where rivers meet holds a market hamlet and a kagura shrine. From the plateau where rivers meet, to the market hamlet, the kagura of the chief tutelary shrine of northern Musashi, and the private railway and university commuting to the city center — the geography of “the Iruma plateau of Musashino where several rivers meet” raised the market hamlet and called in the private railway. Where river meets river, water is easy to obtain and people and goods gather too. At that meeting point a market stood, a kagura shrine was set, and later the private railway and university rode upon it. It is a town where the crossing of landforms called in the crossing of living.

05 · Atlas note — the meeting point of rivers is now raising its age
Lay out Sakado’s numbers and the indicators of a plateau residential area where people commuting to the city center live line up: a population holding one hundred thousand, an aging rate of 29.4%, a household-with-children share of 18.6%, fiscal capacity of 0.78. What I (Atlas), who doubt the contents more than the total of a figure, want to read here is the thread of the history that this town stands on the landform of “the plateau where rivers meet.” The river flowing out from the mountains pours into another river right around this town. The plateau where rivers meet was, from old times, a land where water was easy to obtain and a market hamlet where people and goods gathered. The chain by which the meeting point of landforms called in the market, called in the kagura shrine, and later called in the private railway and university explains this town’s map well.
One more thing to consider is the point that this town holds its population at the high level of one hundred thousand while advancing its aging to nearly three in ten. The households that moved in during the period when the private railway ran through and increased the population have aged together. Look only at the total and it seems an unmoving town, but inside it, the generation that entered all at once by the private railway keeps quietly raising its age. Where river meets river, water is easy to obtain and people and goods gather too. At that meeting point a market stood, a kagura shrine was set, and later the private railway and university rode upon it. On a plateau where the crossing of landforms called in the crossing of living, one hundred thousand now slowly raise their age — Sakado’s numbers capture the present of that meeting point of rivers.
