Toyota-shi

In the latest Population Census the population is about 422,000 (422,330 in 2020). From 422,542 in 2015 it has moved roughly level. It is a city in a phase of stability, neither increasing nor decreasing.

That said, the number of children shows a direction of its own, apart from the total. Those under 15 fell by over four thousand in five years, from 60,357 (2015) to 56,365 (2020). In the same period the share aged 65 and over rose from 20.7% to 23.1%. Two currents run at once: behind a total population that holds level, the inside shifts its center of gravity steadily toward the older side. The household-with-children share is 22.5% (2020), placing it on the thick side. The Official Land Price for residential land is around 110,000 yen per m² (109,500 yen, 2026), a low level compared with coastal cities of similar population. The Fiscal Capacity Index is 1.34 (2023), among the highest of cities nationwide, greatly exceeding 1.0 — an independent fiscal structure that, hardly relying on the local allocation tax, can fully cover standard expenditure with its own tax revenue alone. The Childcare Waitlist is zero (2025). Why these numbers take this shape cannot be read without going back over the history of the castle town and sericulture, and the automobile industry.

Toyota’s skeleton is the very history of a single land that loaded one industry onto itself twice and three times over. In the Edo era this place was called Koromo, and the Koromo domain was set here. A castle was raised on the heights of Doshiyama, and the town opened as a castle town. It is, in historical geography, the typical case of a town set with a domain’s castle at its core.

The second foundation is sericulture and silk-reeling. From the Meiji into the Taisho era, the town of Koromo developed around sericulture and silk-reeling, until it came to be called a "town of silkworms." But once the Showa era came, demand for raw silk at home and abroad thinned rapidly. A town dependent on a single industry faced the decline of that industry.

And so a third phase arrived. To win back its prosperity, the town moved, in a town-wide effort, to attract an automobile-industry plant. In 1938 the Koromo Plant of Toyota Motor Co. was completed on Ronjigahara (now Toyota-cho), and the production of automobiles began. The town, which became Koromo City in 1951, changed the very name of the city to "Toyota City" in 1959. It was a renaming reached after debate that split the city in two. A town that flourished by sericulture drew in automobiles upon the decline of raw silk, and at last gave the name of the city over to an industry — thus, in economic geography, a company town was formed. What should be noted here, though, is that this is less the story of a single firm than the structural story of a town that replaced a declining industry with another. From a castle town, through a town of silkworms, to the company town of an automobile industry — this city’s numbers stand upon a history of loading one industry after another.

What characterizes Toyota is that, while the total population holds level, the number of children has fallen by four thousand. That appears in the numbers of living infrastructure as a quiet turnover, different both from new construction and from consolidation. The total population does not move because the households moving in and the households finishing their child-rearing roughly balance. Behind that balance, those under 15 thin gently. The household-with-children share, at 22.5%, is thick, and the history of having gathered workers and their families as the company town of an automobile industry appears in the thickness of that child-rearing layer.

The Childcare Waitlist is zero. What I want to note here is that, despite the thick share of child-rearing households, the waitlist is zero, in which can be read that the high fiscal capacity of 1.34 has made the supply of childcare keep pace with demand in advance. It is reasonable to read this not as a zero reached after the absolute number of children thinned to the end, but as a zero achieved where supply outran demand while the child-rearing layer stayed thick. The entry point differs, in fiscal headroom, from a great city like Nagoya that struggles with its waitlist. That a population holding level, gently declining children, and yet a zero waitlist can coexist in one city is because the fiscal headroom born of the automobile industry’s agglomeration runs ahead of childcare demand. Beneath a number that looks placid — holding level — the thickness of finances quietly lifts the living infrastructure.

Toyota holds several functions of its own. One is its face as the company town of an automobile industry, where the related plants and the parts industry agglomerate within the city area, and keep this town’s origin inscribed upon the map. Another is the Yahagi River that runs through the city area, and the mountain forest of the Mikawa Highlands that occupies most of the city. While industry gathers on the flat land of the urban area, much of the broad city area is occupied by mountains and the river.

Toyota opened as a castle town, passed through a town of silkworms, and changed its form into the company town of an automobile industry. The castle, the silk-reeling plant and the automobile plant were all, in origin, set upon the same condition — the flat land that opened along the basin of the Yahagi River. And the mountain forest of the Mikawa Highlands remains broadly along the city’s rim. A two-layered city area — the flat land bearing industry, the forest bearing the water source and nature — shapes the geography of this town that holds broad nature even while being an industrial city. From a castle town, to a town of silkworms, and to the company town of automobiles, the same flat land that opened along the Yahagi River basin loaded the castle, the silk-reeling plant and the automobile plant onto itself age by age, while the mountain forest of the Mikawa Highlands kept enclosing its outer edge.

Lay out Toyota’s numbers and indicators supported by high fiscal headroom line up: a population holding level, a fall in children, a fiscal capacity of 1.34, and a zero waitlist. But to my eye (Atlas), used to ledgers, the present number of one of the highest fiscal capacities in the country can be read as the consequence of the history of "replacing a declining industry with another." When a town of sericulture draws in an automobile industry and plants and a parts industry agglomerate within the city area, thick tax revenue piles up from corporations and workers, the fiscal capacity greatly exceeds 1.0, and the structure becomes independent, hardly relying on the local allocation tax. The zero waitlist and the thickness of child-rearing households are not separate merits, either, but results branching off from a single trunk — the fiscal headroom born of the industry’s agglomeration.

So the same numbers show two faces at once. The total population does not move, yet children fell by four thousand. Finances are among the highest in the country, yet that thickness is held in the hand of a single industry’s fortunes. The castle town below Shichishu Castle, the silk-reeling of the town of silkworms, the automobile plant, and the mountain forest of the Mikawa Highlands were all loaded, age by age, onto the same flat land that opened along the Yahagi River basin. What should be measured in reading Toyota’s numbers now is which stage this loading-on has reached — where, on the hardest landing of all to read, the one called holding level, the city stands.
