Through the center of this town a single river flows. Once the water transport of this river carried the coal dug out and made the town flourish as a coal town. This land, touching both a northern industrial city and the inland coalfield, brimmed with vigor at the height of the age of coal. But once the nation switched its source of energy away from coal, the mines closed, and the town walked the time after coal afresh as a town where people live. This land, a coal town that flourished by river transport, did not join the Heisei mergers, but walked on alone, losing population. Nakama’s numbers are the record of a town in which the time after coal and the walk alone are inscribed.
A city in the northern part of Fukuoka Prefecture, touching both a northern industrial city and the inland coalfield, that opens in a land through which a river flows at its center. The population fell from 48,032 in 2000 to 40,362 in 2020. This city did not go through the Heisei mergers and has walked on alone, so its recent population course has no step deriving from a merger. What I (Atlas) want to read here is not the sign "a city of the prefecture’s north," but the causal thread: how the history of the time after coal and the walk alone is translated into today’s population and finances.
01 · Seeing the present Nakama in its numbers
In the latest Population Census the population is about 40,000 (40,362 in 2020). This city did not go through the Heisei mergers and has walked on alone, so its recent population course has no step deriving from a merger. From 48,032 in 2000, to 46,560 in 2005, to 44,210 in 2010, to 41,796 in 2015, to 40,362 in 2020, it has fallen gently.
Looking inside, the figure of a residential town walking the time after coal and raising its age appears. The share aged 65 and over rose from 34.9% in 2015 to 37.4% in 2020, nearing four in ten. The household-with-children share is 17.1% (2020), and the crude birth rate is 6.5 per thousand in 2020. As for the Childcare Waitlist, it was zero in 2024, but in 2025 sixteen remained, a year where some slightly remained (waitlist rate 2.2%). This shows that a gap can arise between the households that need childcare and the places to receive them. The Fiscal Capacity Index was 0.45 in fiscal 2023, a level whose own tax revenue can cover only a little under half of expenditure. A coal town that flourished by river transport loses population while alone, without going through a merger. To unravel how this came about, there is no way but to go back over the history of river transport, coal mining and the time after coal.

02 · River transport, a coal town, a residential city of the time after coal, the walk alone — the history behind the numbers
This town’s skeleton is set by the water transport of the river flowing through its center, a coal town that dug coal, the shift to a residential city of the time after coal, and the walk alone. The starting layer is river transport. This town touches both a northern industrial city and the inland coalfield, and a single river flows through its center. The coal dug out was carried by the water transport of this river, making the town flourish as a coal town. The water transport of the river flowing through its center was the foundation of this town.
Supported by this river transport, the town flourished in the age of coal. Until the mid-Showa era, this town brimmed with vigor as a coal town. But once the nation switched its source of energy away from coal, the surrounding mines closed one after another, and the freight rail that carried coal was in time abolished too. The town walked the time after coal afresh as a town where people live, and changed its form into a residential city. The path to becoming a city also reflects this town. In the mid-Showa era, to avoid becoming the periphery of a large city, this town did not unite with its surroundings, and chose independent city status. River transport, a coal town, a residential city of the time after coal, and the walk alone. The history of the time after coal, carved by a coal town that flourished by river transport, has set the present shape of the town.

03 · In a coal town that flourished by river transport, losing population while alone
What characterizes Nakama is that, while it holds the history of the time after coal, it has been losing population while alone, without going through a merger. From 48,032 in 2000 to 40,362 in 2020, some eight thousand were lost over twenty years. Even in this land that changed its form from a coal town to a residential city, part of the young generation moved toward larger cities, and one can read that the age of the town as a whole rose. That the share aged 65 and over neared four in ten at 37.4% in 2020 is an expression of that.
On the other hand, as for the Childcare Waitlist, it was zero in 2024, but in 2025 sixteen remained, a year where some slightly remained. Even in a town where the population declines, this number honestly shows that a gap can arise, year by year, between the households that need childcare and the places to receive them. The household-with-children share is 17.1% (2020), and the crude birth rate is 6.5 per thousand in 2020. The Fiscal Capacity Index of 0.45 is a level whose own tax revenue can cover only a little under half of expenditure. The population fell by some eight thousand in twenty years, the aging nears four in ten, and years of a zero waitlist and years where some remain are mixed together. These are moving upon the history of a residential town of the time after coal, and the figure of this town cannot be fully captured by any single number.

04 · A coal town that flourished by river transport walks the time after coal as a residential town
In Nakama, several functions of differing histories are folded together. One is the old layer of river transport, where, touching both a northern industrial city and the inland coalfield, it carried coal by the water transport of the river flowing through its center and flourished. Another is its character as a residential city of the time after coal, where, after the source of energy switched and the mines closed, it changed its form into a town where people live. And it holds the face of the walk alone, choosing independent city status to avoid becoming the periphery of a large city. The position that carried coal by river transport drew the coal town, and then the residential town of the time after coal, into this land.
Touching both a northern industrial city and the inland coalfield — under this position, river transport gave rise to a coal town that carried coal, and in the time after coal it changed its form into a residential town, and the framework of the town came into being. After the foundation of coal was pulled out, this town walked afresh as a town where people live. That plain changeover, from a town that digs to a town where people live, is what decides the outline of Nakama today.

05 · Atlas’s note — a coal land of river transport that switched from a town that digs to a town where people live
Lay out Nakama’s numbers and the indicators of a residential town walking the time after coal line up: a population declining while alone, an aging rate of 37.4%, a household-with-children share of 17.1%, years of a zero waitlist and years where some remain mixed together, and a fiscal capacity of 0.45. But to my eye (Atlas), used to handling numbers, what I want to read here is the way of walking after the industrial foundation was pulled out — that this town "walked afresh, from a coal town that flourished by river transport, into a town where people live." A town that lost coal, its core industry, survived by changing its form into a town where people live. The chain by which it found a role as a place to live and walked on even after its core industry was pulled out explains this town’s numbers well.
Another thing I want to consider is that the childcare-waitlist figure moves year by year — "zero in 2024, sixteen in 2025." Even in a town where the population declines, a gap can arise, year by year, between the households that need childcare and the places to receive them. One cannot simply say that because the population declines there is room to spare in childcare. By the total of population alone, the fine detail of daily life cannot be measured. To reckon this town, which switched from a town that digs to a town where people live, by the distance to one’s workplace, by the affordability of a home, or by the openings in childcare — depending on which scale you apply the gathered facts to, the answer divides into several, and the one who chooses what lies beyond is the very person who lives there.
