Suzuka-shi

In the latest Population Census the population is about 196,000 (195,670 in 2020). From 196,403 in 2015 it fell by about seven hundred over five years. As a total it is a Mie city at an almost-level stage.

What I want to note here is the movement of the number of children. Those under 15 fell by nearly four thousand in five years, from 26,758 (2015) to 22,929 (2020). Behind a total population that holds at level, the number of children surely thins. In the same period the share aged 65 and over rose from 23.2% to 24.5%. From this one can read that the stability of the total proceeds together with a shift of the center of gravity toward the older side. The household-with-children share is 20.4% (2020). The Official Land Price for residential land is around 41,000 yen per m² (40,600 yen/m², 2026), a restrained level. The Fiscal Capacity Index is 0.86 (2023), a level whose own tax revenue can cover much of expenditure. 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 the naval arsenal.

Suzuka’s skeleton is the very history of several old urban districts bound into one by the convenience of the military, from whose site industry grew. This area in the early modern era was a land where the castle town of Kanbe, the harbor town of Shiroko, and rural townships existed dispersed. The geography of urban districts of differing character scattered, not gathered at a single center, is this town’s starting point.

The first foundation that decided its fate is the navy. In 1942 (Showa 17), for the purpose of operating the Suzuka Naval Air Corps and the naval arsenal as one body, naval-led mergers of towns and villages were advanced, the dispersed districts were bundled, and Suzuka City was launched. The Suzuka Naval Arsenal was formally launched the next year, 1943 (Showa 18). The military’s need bound the divided land into the shape of one city. The "formation of a city around a military base," in economic geography, decided this town’s outline.

After the war the leading role changed to the engine. Onto the broad, consolidated land that was the arsenal’s site, factories sited themselves. In 1960 (Showa 35), Honda Motor Co. began operating its Suzuka Factory on the arsenal site. At first it was a production base for the two-wheeler Super Cub. And in 1962 (Showa 37), the company opened the Suzuka Circuit. The production of two-wheelers and four-wheelers, and a stage for motorsport, came together in the same town. A castle town and a harbor town bound by the navy, and from that site the engine industry grew — this town’s shape stands upon a history in which the military and the engine took the leading role by turns.

What characterizes Suzuka is that, while the total population holds almost level, the number of children fell by nearly four thousand in five years. The stability of the total does not mean the stability of the inside. The absolute number of children surely thins, and the share of the elderly rises. Even a town that has held its population while holding industry has its inside quietly move toward the older side.

The Childcare Waitlist is zero (2025), and the household-with-children share is 20.4% (2020). A figure of a zero waitlist can be read as a state in which the supply of childcare keeps pace with demand amid an absolute number of children that is thinning. It differs in meaning from a zero a town of ever-increasing children reached by making supply keep pace. Even the same "zero waitlist" reads entirely differently depending on whether children behind it are rising or thinning. Suzuka’s zero is the latter — a zero on the side where children thinned. In a town where the total holds level, children decline and the share of the elderly rises, the number on the waitlist, too, will in time converge to zero. Take out the result "zero" alone and make it material for reassurance, and you overlook the thinning of children proceeding behind it.

Suzuka holds several functions of its own. One is the automobile and motorcycle factory sited on the arsenal’s site, which forms the core of the town’s industry as a production base for two-wheelers and four-wheelers. Another is the Suzuka Circuit the same company opened, which, as one of the nation’s foremost stages for motorsport, gathers people from across the country and characterizes this town as a town of racing. Furthermore, the dispersed old districts — Kanbe, which had been a castle town, and Shiroko, which had been a harbor town — leave on the map the origins from before they were bundled by the military.

Suzuka is a town where divided old districts were bound by the navy and the engine industry grew from that site. The castle town, the naval arsenal, the automobile factory and the circuit were all, in origin, set age by age upon the same condition — the consolidated flat land facing Ise Bay. The castle town, the naval arsenal, the automobile factory and the circuit have all been set age by age on the flat land facing Ise Bay. What bound the divided old districts was the need of the military, and the rare broad land that was that arsenal’s site drew in, after the war, the engine industry.
