Sano-shi

In the latest Population Census the population is about a hundred and sixteen thousand (116,228 in 2020). This city’s population has a large step from the merger. In 2005 the old Sano City, Tanuma town and Kuzu town — one city and two towns — newly merged into the present municipal area. What was 83,414 in 2000 for the old Sano City alone became, after the merger in 2005, 123,926 — the figure of the three combined — and from there, through 121,249 in 2010 and 118,919 in 2015 to 116,228 in 2020, it has fallen gently since the merger.

Looking inside the figures, the figure of a northern-Kanto city appears. The share aged 65 and over, at 30.6% in 2020, passes three in ten. The household-with-children share is 20.0%, and the Childcare Waitlist was zero in 2024 and three in 2025 — very few. The Fiscal Capacity Index was 0.70 in fiscal 2023 — a level covering about seven-tenths of expenditure with its own tax revenue, higher than the middle for a regional city. The figure of the town of casting and warding off ill fortune, gently losing population after the merger while keeping its fiscal stamina in the middle range, appears in the numbers. Why it took this shape does not come into view without going back over the history of casting and faith.

Sano’s skeleton is set by the geography of the northern edge of the Kanto Plain and by the handwork honed there. This land’s casting is called “Tenmyo casting” and is said to have a history of more than a thousand years. From art crafts such as temple bells, Buddhist images, tea kettles and lanterns, to everyday goods such as pots and farm tools, the casters of Sano have melted iron and cast all manner of things. Later, in response to the shift of demand, they widened their work into the field of machine-industry parts. In economic geography it is a typical case of a place of manufacturing where raw materials and skill took root in a single region.

The town has a core of faith. Soshu-ji temple, handed down as founded by Fujiwara no Hidesato, is generally known by the popular name “Sano Yakuyoke Daishi,” and at the turn of the year gathers many worshippers praying to ward off ill fortune. The handwork of casting and the faith of warding off ill fortune have made this town’s name known far.

And in the present age this town gained one more history. The 2005 merger. To the old Sano City were added Tanuma town, rich in forest, and Kuzu town, long and narrow from north to south, making a city of more than a hundred and twenty thousand people. The casting town, through the Heisei merger, changed its shape into a core city of the northern edge of the Kanto Plain. Beginning with a thousand years of casting, bearing the faith of warding off ill fortune, and one city and two towns becoming one. The geography of the northern edge of the Kanto Plain rooted the handwork of treating iron, gathered the waves of worshippers, and later became the foundation for joining the surrounding towns.

What characterizes Sano-shi is that, even while bearing a thousand years of casting and a core of faith known across the country, it gently loses population after the merger. From 2005, right after the merger, to 2020, the population fell by nearly eight thousand. The manufacturing centered on casting changed its weight with the times, and, in the flow of the younger generation leaving toward Tokyo and nearby cities, the descent of population and the advance of aging can be read as occurring gently. That the share aged 65 and over passes three in ten is the expression of this too.

Even so, the fiscal stamina holds in the middle range. A Fiscal Capacity Index of 0.70 is a level covering about seven-tenths of expenditure with its own tax revenue, on the higher side for a regional city. To the agglomeration of manufacturing that widened from casting to machine industry, distribution and commerce that make use of the location along the Tohoku Expressway are added, and these can be read as lending a degree of thickness to the tax source. The Childcare Waitlist too is very few — zero in 2024 and three in 2025. The town of a thousand years of casting and warding off ill fortune now gently loses population while keeping its fiscal stamina in the middle range. Gently decreasing population, aging past three in ten, and yet a kept middle-range finances — this gait can be read as the expression of the thousand-year town of manufacturing keeping the thickness of its tax source while turning over the content of its industry, from casting to machine industry and further to distribution along the Tohoku Expressway.

In Sano several faces the northern edge of the plain drew overlap. One is the history of being a place of Tenmyo casting with a history of more than a thousand years, holding the origin of a manufacturing that cast everything from bells to everyday goods, and later machine parts. Another is Sano Yakuyoke Daishi, handed down as founded by Fujiwara no Hidesato, keeping a core of faith that gathers worshippers at the turn of the year. And the character of a land of traffic at the northern edge of the Kanto Plain, lying along the Tohoku Expressway, gives this town the face of a town of distribution and commerce.

From a place of a thousand years of casting, to a town of faith holding the Daishi of warding off ill fortune, to a core city in which one city and two towns became one. The geography of opening onto the northern edge of the Kanto Plain, with a trunk toward the Tohoku running through, has drawn manufacturing, faith and distribution to the same single land. Whether one sees the thousand-year handwork of casting iron, or the waves of people filling the approach at the turn of the year, or the cluster of warehouses along the expressway — which face one calls to mind first divides by what one came to this town seeking.
