In this town, three rivers join into one. The great river coming from the north, the river coming from the east, and the river coming from the west draw close together here, and then flow down as a single great river. On the mountain that looks down on that confluence, a shrine built more than a thousand years ago lies enshrined. The court, the warrior houses, and the common people all revered that shrine deeply. Before the shrine’s gate a town opened, welcoming those who came to worship. But in the Showa era, when great housing estates were built at the mountain’s foot, the town’s population suddenly swelled, and it became a city. The shrine-gate town where three rivers meet is now gently shedding population. Yawata’s numbers are the record of a town inscribed with the history of the faith of a shrine and the building of housing estates.
A city in the southern part of Kyoto Prefecture, on a land where three rivers join into a great river, holding an old shrine on the mountain that looks down on the confluence. The population has gently fallen, from 73,682 in 2000 toward 70,433 in 2020. This city, since enforcing city status past the middle of the Showa era, has walked on its own through no Heisei merger, so there is no merger-caused step in the recent movement of the population. What I (Atlas) want to read here is not the sign "shrine-gate town," but the causal thread: how the history — the faith of a shrine and the building of housing estates — is translated into today’s population and finances.
01 · Seeing the present Yawata in its numbers
In the latest Population Census the population is about 70,000 (70,433 in 2020). Because this city has walked on its own through no Heisei merger, there is no merger-caused step in the recent movement of the population. From 73,682 in 2000, through 74,252 in 2005, 74,227 in 2010, 72,664 in 2015, to 70,433 in 2020, it has gently fallen after a spell of holding level.
Looking inside, the figure of a town that swelled with the building of housing estates, now raising its age, appears. The share aged 65 and over rose from 13.0% in 2000 to 21.5% in 2010, 28.2% in 2015, and 31.3% in 2020 — by more than eighteen points over twenty years. The household-with-children share is 19.3% in 2020, and the crude birth rate is low, at 4.6 per thousand in 2020. The Childcare Waitlist is zero in both 2024 and 2025. The Fiscal Capacity Index was 0.63 in fiscal 2023, a comparatively thick level able to cover a little over six-tenths of expenditure with its own tax revenue. The figure of the shrine-gate town where three rivers meet, raising its age while gently shedding population, appears in the numbers. Why it takes this shape cannot be read without going back over the history of the land where three rivers meet, the shrine-gate town, and the building of housing estates.

02 · The land where three rivers meet, the shrine-gate town, the building of housing estates, the solitary course — the history behind the numbers
This town’s skeleton is set by its position at the land where three rivers meet, and by the shrine-gate town, the building of housing estates, and the solitary course. The beginning layer is the land where three rivers meet. This land, in the southern part of Kyoto Prefecture, spreads at the foot of the mountain at the confluence where three rivers coming from the north, east, and west join into one and then flow down as a single great river. The land where three rivers meet was this town’s foundation.
On the mountain that looks down on this confluence, more than a thousand years ago, a shrine was built. The court, the warrior houses, and the common people all revered that shrine deeply, and at the mountain’s foot a shrine-gate town opened that welcomed those who came to worship. The faith of the shrine long supported the life of this land. But in the Showa era, when great housing estates were built one after another at the mountain’s foot, the town’s population suddenly swelled. The shrine-gate town and the building of housing estates overlapped on this land. The road to becoming a city mirrors this town too. This town, its population greatly increased by the building of housing estates, enforced city status past the middle of the Showa era as the eleventh city in the prefecture. The land where three rivers meet, the shrine-gate town, the building of housing estates, and the solitary course — this town’s shape stands upon the history of a shrine-gate, before a shrine enshrined on the mountain of the land where three rivers meet, swollen by housing estates.

03 · In the shrine-gate town where three rivers meet, gently shedding population after the building of housing estates
What characterizes Yawata is that, with the old history of a shrine-gate town and the new history of the building of housing estates overlapping, it is now gently shedding population. From 73,682 in 2000 to 70,433 in 2020, after a spell of holding level, a little over three thousand were lost over twenty years. That the generation which moved in all at once during the Showa building of housing estates is aging together lies behind the gentle loss of population and the steep advance of aging. That the share aged 65 and over rose from 13.0% in 2000 to 31.3% in 2020 — by more than eighteen points over twenty years — is its expression.
On the other hand, the Childcare Waitlist is zero in both 2024 and 2025, the household-with-children share is 19.3% in 2020, and the crude birth rate is 4.6 per thousand in 2020. The Fiscal Capacity Index of 0.63 is a comparatively thick level able to cover a little over six-tenths of expenditure with its own tax revenue. The old time of the thousand-year shrine-gate and the new time of the Showa housing estates overlap within the same city area. That the aging rate was pushed up by more than eighteen points over twenty years is because the latter generation aged together. The wave of a new generation grafted onto an old town is now moving the numbers of the whole town.

04 · A shrine-gate, before a shrine enshrined on the mountain of the land where three rivers meet, swelled with housing estates
Yawata holds several functions of its own. One is the history of the land where three rivers meet, where three rivers coming from the north, east, and west join into one and then flow down as a great river. Another is its character of a shrine-gate town, before a shrine built more than a thousand years ago on the mountain at that confluence, which drew the faith of the court, the warrior houses, and the common people. And it holds the face of the building of housing estates, where great housing estates were built at the mountain’s foot in the Showa era and the population swelled. On the land where three rivers join into one, the shrine on the mountain and the Showa estates at its foot have piled up. A land where rivers gather produces fertile flat land and, at the same time, gathers water as well.
That the old shrine was deliberately built on the mountain that looks down on the water mirrors this land’s long way of keeping company with water. Whether one takes convenience or places preparedness first — by how that balance tips, Yawata’s numbers change their expression.

05 · Atlas’s note — the Showa estates grafted onto a thousand-year shrine-gate called up a wave of age
What makes me (Atlas) pause as I gaze at Yawata’s numbers is that the old time axis of a thousand-year shrine-gate and the new time axis of the Showa housing estates overlap within the same city area. That the aging rate rose so steeply, by more than eighteen points over twenty years, is not the natural thinning of an old shrine-gate town, but because the generation which moved in all at once into the Showa estates is aging together. When new estates are grafted onto an old shrine-gate town, the wave of age of that estate generation moves the whole town’s numbers all at once. The old time and the new time overlap in one town — it is precisely at this graft that I pause before Yawata’s numbers.
One more thing I want to keep in mind is that this town is set on a land where water gathers — where "three rivers meet." A land where rivers meet is a keystone of water transport, and produces fertile flat land while, at the same time, being a land where water gathers. To live on a land where water gathers is to count both convenience and preparedness. That the old shrine was built on the mountain that looks down on the water also mirrors this land’s way of keeping company with water. The land where three rivers meet brings the convenience of water transport and fertile flat land while, at the same time, being a land where water gathers. That the old shrine was built on the mountain that looks down on the water mirrors this land’s way of keeping company with water. Convenience and preparedness are the front and back of one and the same landform.
