This land opens on level paddies descending toward the Ariake Sea and on the slopes of the hills behind them. On the hillsides, mandarin trees are planted in terraces; on the level paddies, rice ripens. This farming land that yields fruit and rice faces the neighboring city across a great river to the north, and to the south crosses the prefectural border to adjoin the neighboring prefecture. Three towns were bound into one, and the present city was established. The city’s name is written not in Chinese characters but in soft hiragana. This land of mandarins and rice by the Ariake, having bound three towns into a city, has quietly lost population since the merger. Miyama’s numbers are the record of a town in which a merger of three towns and a farming past are inscribed.
A city that opens in southern Fukuoka Prefecture, on level paddies and hillsides descending toward the Ariake Sea. Because this city was established in 2007 by binding three towns anew into one, its population statistics as a city cover the period from 2010, after the establishment, on. From the 40,732 of 2010 to the 35,861 of 2020, it has decreased. What I (Atlas) want to read here is not the sign "a city of the prefecture’s south," but the causal thread: how the history — a merger of three towns and a farming past — is translated into today’s population and finances.
01 · Seeing the present Miyama in its numbers
In the latest Population Census the population is about 36,000 (35,861 in 2020). Because this city was established in 2007 by binding three towns anew into one, its population statistics as a city cover the period from 2010, after the establishment, on. From the 40,732 of 2010, to the 38,139 of 2015, to the 35,861 of 2020, some five thousand have been lost over ten years.
Looking inside, the figure of a farming land yielding fruit and rice raising its age appears. The share aged 65 and over rose from 34.8% in 2015 to 38.3% in 2020, nearing four in ten. The household-with-children share is 20.6% (2020), and the crude birth rate is 5.5 per thousand in 2020. The Childcare Waitlist was zero in both 2024 and 2025. The Fiscal Capacity Index was 0.41 in fiscal 2023 — a level able to cover only a little over four-tenths of expenditure with its own tax revenue, leaning heavily on the local allocation tax. This Ariake land, ripening mandarins on the hills and rice on the flat, has aged while losing population after the merger. That curve comes into view by tracing the landform of level paddies descending toward the Ariake Sea and the hills behind them, the two kinds of farming of fruit and rice, and the history of a merger of three towns.

02 · Paddies and hills descending to the Ariake, mandarins and rice, a river and a prefectural border, a merger of three towns — the history behind the numbers
This town’s skeleton is set by the landform of flatland and hills descending toward the Ariake Sea, the farming of mandarins and rice, the position of river and prefectural border, and the merger of three towns. The starting layer is the flatland and the hills. This land opens on level paddies descending toward the Ariake Sea and on the slopes of the hills behind them. These two landforms — level paddies and hillsides — have set this land’s farming.
These two landforms gave birth to two kinds of farming. On the hillsides, mandarin trees are planted in terraces and yield fruit; on the level paddies, rice ripens. This is a farming land ringed by many borders: to the north it faces the neighboring city across a great river, and to the south it crosses the prefectural border to adjoin the neighboring prefecture. The path to becoming a city also reflects this town. In 2007 three towns were bound anew into one, and the present city was established. The city’s name was written not in Chinese characters but in soft hiragana. Flatland and hills descending to the Ariake, mandarins and rice, a river and a prefectural border, and a merger of three towns — this town’s form stands upon the history of farming and merger, carved by the flatland and hills descending toward the Ariake Sea.

03 · In a land of mandarins and rice by the Ariake, losing population after the merger
What characterizes Miyama is that, while it holds the history of farming of fruit and rice, it is losing population after the merger. From the 40,732 of 2010, after the city was established, to the 35,861 of 2020, some five thousand were lost over ten years. Even in this farming land yielding mandarins and rice, one can read that some of the younger generation moved toward the larger cities and the town’s age as a whole rose. That the share aged 65 and over reached 38.3% in 2020, nearing four in ten, is an expression of that.
On the other hand, the Childcare Waitlist was zero in both 2024 and 2025, the household-with-children share is 20.6% in 2020, and the crude birth rate is 5.5 per thousand in 2020. The Fiscal Capacity Index of 0.41 is a level able to cover only a little over four-tenths of expenditure with its own tax revenue, showing the heavy reliance on the local allocation tax seen in common across farming lands that yield fruit and rice. The land of mandarins and rice by the Ariake is aging while losing population after the merger. The population lost after the merger, the aging nearing four in ten, and the finances thin on tax revenue alone are not separate numbers; they are expressions, in separate figures, of the same single flow by which, in a farming land yielding fruit and rice, some of the younger generation move toward the larger cities.

04 · A flatland and hills descending to the Ariake have raised the two kinds of farming, mandarins and rice
Miyama has several faces held by the landform descending toward the Ariake. The history of flatland and hills, opening on level paddies descending toward the Ariake Sea and on the slopes of the hills behind them. The face of a farming land of fruit and rice, planting mandarin trees in terraces on the hillsides and ripening rice on the level paddies. And the face of a land ringed by many borders, facing the neighboring city across a great river to the north and crossing the prefectural border to adjoin the neighboring prefecture to the south.
Miyama is a town where the flatland and hills descending to the Ariake have raised the two kinds of farming, mandarins and rice. The same landform ripens fruit on the slopes and rice on the flat. This farming land, ringed by the prefectural border and a great river, lies on a periphery where the pull of every metropolitan sphere reaches equally weakly — and it is that very distance that has kept to this day a livelihood centered on orchard and paddy.

05 · Atlas’s note — reading, in a land of mandarins and rice by the Ariake, a peripheral position ringed by borders
Lay out Miyama’s numbers and the indicators of a farming land yielding fruit and rice line up: a population falling after the merger, an aging rate of 38.3%, a household-with-children share of 20.6%, and a fiscal capacity of 0.41. But to put it with the habit of one (Atlas) who checks what the land has yielded before the numbers, what I want to read here is that this town "holds together two landforms — level paddies descending toward the Ariake Sea and the slopes of the hills behind them." The level paddies yield rice; the hillsides yield mandarins. Because there are two landforms in one place, two kinds of farming, rice and fruit, struck root in the same town. The chain by which the overlap of landforms widened the breadth of farming explains well the thickness of this town’s agriculture.
Another thing I want to consider is that this town lies in a position ringed by many borders — "facing the neighboring city across a great river to the north, and crossing the prefectural border to adjoin the neighboring prefecture to the south." At the southern edge of the prefecture, touching several borders, this position is also a peripheral land where the pull of every metropolitan sphere reaches equally weakly.
The southern-edge position, ringed all about by a great river and a prefectural border, is equally far from every metropolitan sphere, and for that reason has strengthened a farming character centered on orchard and rice. Whether to view this land as a rice country spreading toward the Ariake, or as a producing district of mandarins ripening on the hillside terraces, divides with where one places the weight of one’s living. The southern-edge position, ringed all about by a great river and a prefectural border, is equally far from every metropolitan sphere, and for that reason has strengthened a farming character centered on orchard and rice.
