On one mountain in a corner of this city are the ruins of a great castle, raised over the whole mountain by a clan that made this land its seat in the Warring States era. The parable of the three arrows, hard to break, said to be how the castle’s lord preached unity to his sons, is still told as this land’s story, and, joined to a word from across the sea, became the name of a group in a certain sport as well. In this land among the mountains, a rural kagura — danced in masks to flute and drum — has been handed down in a form famed throughout the nation. This town, the land where a mountain-castle lord preached the three arrows, was born in the Heisei era when six towns became one, and has lost population. Akitakata’s numbers are the record of a town etched by the history of a castle and kagura.
A city among the mountains that opens on the upper reaches of the Go River in the northern part of Hiroshima Prefecture. After six towns became one in 2004 and the city was founded, the population fell, from 33,096 in 2005 to 26,448 in 2020. Because this city was founded by a new merger, its recent population is read on the broad post-founding city area. What I (Atlas) want to read here is not the sign "a city of the prefecture’s north," but the causal thread: how the history — a castle and kagura — is translated into today’s population and finances.
01 · Seeing the present Akitakata in its numbers
In the 2020 Population Census, this city’s population is 26,448 — about twenty-six thousand. Because this city was newly founded in 2004 when six towns became one, the statistics are read on the broad post-founding city area. On that area it has fallen, from 33,096 in 2005, to 31,487 in 2010, to 29,488 in 2015, to 26,448 in 2020.
Looking inside, the figure of a land of castle and kagura among the mountains raising its age greatly appears. The share aged 65 and over was 42.0% in 2020, passing four in ten. The household-with-children share was 15.9% in 2020, and the crude birth rate was 4.2 per thousand in 2020. The Childcare Waitlist was zero in both 2024 and 2025. The Fiscal Capacity Index was 0.33 in fiscal 2023 — a level able to cover only about a third of expenditure with its own tax revenue. The figure of the land where a mountain-castle lord preached the three arrows, losing population after becoming one with six towns, appears in the numbers. Why it takes this shape cannot be read without going back over the history of the castle, kagura and the merger.

02 · A castle spread over the whole mountain, the parable of the three arrows, rural kagura, and the merger of six towns — the history behind the numbers
This town’s skeleton is set by the history of a castle spread over the whole mountain, the parable that preached unity, the rural kagura, and the merger of six towns. The first layer is the castle. On one mountain in a corner of this city are the ruins of a great castle, raised by a clan that made this land its seat in the Warring States era, spread from a single enclosure over the whole mountain. The seat of a clan that made the whole mountain its castle was this town’s old foundation.
The parable of the three arrows, hard to break, said to be how this castle’s lord preached unity to his sons, is still told as this land’s story. That parable, joined to a word from across the sea, became the name of a group in a certain sport as well. In this land among the mountains, a rural kagura — danced in masks to flute and drum — has been handed down in a form famed throughout the nation. The road by which it became a city mirrors this town, too. In 2004 six mountain towns became one and were newly founded. A castle spread over the whole mountain, the parable of the three arrows, rural kagura, and the merger of six towns — this town’s shape stands upon the history of castle and kagura, etched by the seat of a clan that made the whole mountain its castle.

03 · In the land where a mountain-castle lord preached the three arrows, becoming one with six towns and losing population
What characterizes Akitakata is that, while bearing the history of a castle and kagura, it has lost population after becoming one with six towns. On the post-founding city area, about seven thousand fell over fifteen years, from 33,096 in 2005 to 26,448 in 2020. In this city, which holds a broad area among the mountains, one can read that the young generation has moved from the mountain settlements added by the merger toward the city center and larger cities, and that the age of the whole town has risen greatly. That the share aged 65 and over passed four in ten at 42.0% in 2020 is one expression of this.
Meanwhile the Childcare Waitlist was zero in both 2024 and 2025, the household-with-children share was 15.9% in 2020, and the crude birth rate was 4.2 per thousand in 2020. The Fiscal Capacity Index of 0.33 is a level able to cover only about a third of expenditure with its own tax revenue. This land, where the castle’s lord is said once to have preached unity, now binds six towns into one. Yet on the bound city area aging passes four in ten, and the younger the mountain village added by the merger, the faster its outflow of the young. A town that hands down the parable of unity is being asked about the very shape of unity, one might also read.

04 · The castle decayed; the arrow-tale and the kagura remained
Akitakata’s old foundation is a castle raised over the whole mountain. A clan that made this land its seat in the Warring States era spread the castle from a single enclosure over the whole mountain. That castle has decayed, and only the ruins remain.
But something has lasted longer than what had form. The parable of the three arrows, said to be how the castle’s lord preached unity to his sons, is still told as a story, and, joined to a word from across the sea, became the name of a group in a certain sport as well. The rural kagura, danced in masks to flute and drum, has been handed down in a form famed throughout the nation. The castle decayed, the arrow’s anecdote remains as words, and the kagura is still danced on with mask, flute and drum. In this land on the upper Go River, what is told on and danced on has put down deeper roots in the town than what had form.

05 · Atlas’s note — reading Akitakata’s numbers together with its history
Lay out Akitakata’s numbers and the indicators of a mountain city raising its age greatly line up: a population falling after the merger, an aging rate of 42.0%, a household-with-children share of 15.9%, and a fiscal capacity of 0.33. What I care about, more than the line of indicators, is rather the discrepancy between fame and figures — that the story of a Warring-States clan still has the power to draw people, while the population itself keeps falling. The castle spread over the whole mountain, and the parable that preached unity, are both widely known. But that fame has not yet been translated, in full, into today’s population figures. The power of a story and the number of people who live there are separate indicators.
The other thing that catches me is that this town "still hands down a rural kagura famed nationwide." The kagura, danced in masks to flute and drum, is a work in which people gather and pass handcraft across the generations. Whether such places of gathering remain, even as the population falls, shows a power to carry on that the total of population cannot measure. The parable of the three arrows taught that a single arrow breaks, but three bound together are hard to break. The power to bind people and to carry on the dance — the name Akitakata still stands on the upper reaches of the Go River as the place where that binding power is tested.
