This town is a place where two great highways meet at a single point. The highway joining Edo and Kyoto, and the highway joining Edo and Kai, become one here on the northern shore of Lake Suwa. At that place of confluence, a station before the difficulty of a pass was set, and it flourished as the gate-front town of the shrine of the gods of Suwa, and as one of the few post towns with a hot spring on the highway. When the Meiji era came, this place became a town that reeled raw silk, and in time the hands that handled that precision were handed down to the industry that gives birth to clocks, cameras and music boxes, and this district came to be called "the Switzerland of the East." The station where two highways meet changed its form into a town of precision. Shimosuwa’s numbers are the record of a town inscribed with the history of the confluence station of two highways and the path from silk reeling to precision.
A town in the central part of Nagano Prefecture, opening onto the northern shore of Lake Suwa. This town has walked its history as the sole place where the Nakasendo and the Koshu Kaido meet, flourishing as the gate-front town of the Lower Shrine of Suwa Taisha, and turning after the Meiji era from silk reeling to precision industry. The population has fallen by more than five thousand over twenty years, from 23,930 in 2000, through 22,863 in 2005, 21,532 in 2010 and 20,236 in 2015, to 19,155 in 2020. What I (Atlas) want to read here is not the sign "the Switzerland of the East," but the causal thread: how the history — the confluence station of two highways and the path from silk reeling to precision — is translated into today’s population and finances.
01 · See the present Shimosuwa-machi in its numbers
In the latest Population Census the population is about nineteen thousand (19,155 in 2020). From 23,930 in 2000, through 22,863 in 2005, 21,532 in 2010 and 20,236 in 2015, to 19,155 in 2020, it fell by more than five thousand over twenty years.
Looking inside the figures, the figure of a precision town where two highways meet appears. The share aged 65 and over rose from 23.1% in 2000 to 38.4% in 2020 — about fifteen points over twenty years, drawing near four in ten. The household-with-children share is 18.5% in 2020. The employment rate is 54.0% in 2020. The Childcare Waitlist, at seven in 2024, arose notably among the municipalities of this article, and fell to one in 2025. The Fiscal Capacity Index was 0.53 in fiscal 2023 — a level whose own tax revenue covers a little over half of expenditure, on the higher side among the municipalities lined up in this article. The figure of a place that began as the confluence station of two highways and became a town of precision, losing population while raising the town’s age, appears in the numbers. Why it takes this shape cannot be read without going back over the history of the confluence station and precision.

02 · The confluence of two highways, the gate-front of the Suwa shrine, from silk reeling to precision — the history behind the numbers
A position where two highways meet. A character as the gate-front of the shrine of the gods of Suwa. And the turn of industry from silk reeling to precision. The shape of Shimosuwa-machi is built of these three. The opening layer is the position. The highway joining Edo and Kyoto, and the highway joining Edo and Kai, meet here on the northern shore of Lake Suwa, at a single point, becoming one. At the beginning of the Edo era, when the highways were laid out, the two roads were rerouted to converge at this place, and a station was set at that point of confluence. Before the difficulty of a pass, this station flourished as the gate-front town of the shrine of the gods of Suwa, and as one of the few post towns with a hot spring on the highway. A spirited festival, in which great logs are dragged and raised at the four corners of the shrine once every seven years, still continues. The gate-front station of the shrine, where two highways meet — that is this town’s old foundation.
Upon it rides the turn of industry. When the Meiji era came, this land of Suwa became a town that reeled raw silk. To reel thread evenly and fine takes delicate, precise hands and contrivances. The hands and temperament of precision fostered in that silk reeling were handed down, after the war, to an industry that gives birth to utterly different things: clocks, cameras and music boxes. Under clean air, abundant water and a dry climate, the trades of precision machinery gathered in this district, and it came to be called "the Switzerland of the East." Music boxes, at their peak, were made at one per second, and it is told that this land produced over 90% of the world’s output. The precise hands that reeled thread were handed down to the precision of things that mark time, cast images and play music — that is the course of this town and the district of Suwa. The confluence station of two highways handed the precision of silk down to precision industry — upon that history this town’s present stands.

03 · In a town of precision, the population falls while the stamina of finances is held
What characterizes Shimosuwa-machi is that, while holding the history of the confluence station of two highways and precision, it has, while losing more than five thousand of its population over twenty years, held the stamina of its finances on the higher side among the municipalities of this article. From 23,930 in 2000 to 19,155 in 2020, the fall is about two-tenths. Precision industry has supported this land’s places to work, but amid the move of people to larger cities and the shifts of the world of manufacture, the population has fallen gently. That the share aged 65 and over drew near four in ten at 38.4% in 2020 is an expression of this.
On the other hand, the Fiscal Capacity Index of 0.53 is a level whose own tax revenue covers a little over half of expenditure, on the higher side among the municipalities lined up in this article. This can be read as an expression of how the precision industry handed down from silk reeling still supports the town’s tax source with a certain depth. The Childcare Waitlist, at seven in 2024, arose notably among the municipalities of this article, and fell to one in 2025. This is a number showing that the demand of households raising children upon this town temporarily exceeded the receiving capacity of childcare, and that it is heading toward resolution by 2025. The household-with-children share is 18.5% in 2020, and the employment rate is 54.0% in 2020. A population fall of about two-tenths, an aging drawing near four in ten, and yet a high-side fiscal stamina of a little over half. These three are separate numbers, yet all stem from the same history: that "the precision industry handed down from silk reeling supports the tax source even while people fall." Pull out a single indicator and look at it alone, and the image does not come together.

04 · The confluence station of two highways handed the precision of thread to the precision of machines
Shimosuwa holds several histories of its own. One is the position of being the sole place of confluence where the highway joining Edo and Kyoto and the highway joining Edo and Kai meet at a single point. Another is the character that the confluence station flourished as the gate-front of the shrine of the gods of Suwa, and as one of the few post towns with a hot spring on the highway. And after the Meiji era it became a town that reeled raw silk, and those precise hands were handed down to the precision industry of clocks, cameras and music boxes, and it was called "the Switzerland of the East." The position of the northern shore of Lake Suwa, west of the difficulty of a pass, and the climate of clean air and water, gave this town both the confluence station of two highways and the turn from silk reeling to precision.
Shimosuwa is a town where the confluence station of two highways handed the precision of thread down to the precision of machines. From the confluence of two highways, through the gate-front of the shrine, silk reeling and precision industry, to the population fall and the stamina of finances — the geography of "the place on the northern shore of Lake Suwa where two highways meet" gave this town both an old role, the confluence station, and the precision handed down from thread to machine. The hands that reeled thread evenly and the hands that give birth to clocks and music boxes both stem from the same temperament of "handling precision." The thing changed from thread to machine, but the nature of the hands was handed down.

05 · Atlas note — the hands that reeled thread transferred to the precision of clocks and cameras and remained
Lay out Shimosuwa’s numbers and the indicators of a precision town where two highways meet line up: a population fall of more than five thousand over twenty years, an aging rate of 38.4%, a household-with-children share of 18.5%, and a fiscal capacity of 0.53. But when I (Atlas) read with the accountant’s eye, what draws me here is the point that this town’s fiscal capacity of 0.53 is held on the higher side among the municipalities of this article, even while losing population. While many of the municipalities that lose population in the mountains and highlands can cover only two or three tenths of their expenditure with their own tax revenue, this town covers a little over half. In my view, that difference lies in the history that this town is not a mere post town or farming land, but still holds a trade that gives birth to high-value things — the precision industry handed down from silk reeling.
One more thing to weigh is the linkage by which that precision began from "the hands that reeled thread." The precise hands and temperament that reeled thread evenly and fine were handed down to a precision that gives birth to utterly different things — clocks, cameras and music boxes. The thing itself changed from thread to machine, but the nature of this land’s hands, of "handling precision," was handed down. When one industry ends its role with the age, if the hands and temperament fostered in that industry are handed down to another industry, a town may be spared a steep slope — the course of this town and the district of Suwa is one example of that thread, as I read it. That the Childcare Waitlist arose notably at seven in 2024 and fell to one in 2025 is also, surely, one expression of a certain demand of households raising children upon this town of precision. Whether you read it past as the sign "the Switzerland of the East," or see it as "a town where the confluence station of two highways handed the precision of thread to the precision of machines," changes with how the reader lives. When the age of silk reeling ended, what saved this town from a steep slope was the dexterity of hands that shifted to another thing. The memory of the hands, which remained even after letting go of thread, gives rise to the whole of the present stamina of finances.
