It was nearly five hundred years ago that, at the southern end of this island, a single ship drifted ashore. The people aboard that ship held a tube that strikes fire and looses a ball. The island lord bought it and had the island’s craftsmen make the same. The island where the matchlock gun was first transmitted to Japan — in the north of that island lies the island’s largest port town. Originating in the castle town of the island lord’s residence, it has, as the island’s gateway to the sea, bound the coming and going of people and goods. This land, a port town in the north of the island where firearms were transmitted, has, ever since it became a city in the middle of the Showa era, never once undergone a merger; walking an independent path, it has lost population. Nishinoomote’s numbers are the record of a town in which a gateway to the sea and an independent path are inscribed.
A city that opens onto the north of Tanegashima, of the Osumi Islands in the south of Kagoshima Prefecture. The population has decreased, from 18,866 in 2000 to 14,708 in 2020. Because this city, ever since it attained city status in the middle of the Showa era, has never once undergone a merger and walked an independent path, there is no merger-derived step in its recent population movement. What I (Atlas) want to read here is not the sign "a city in the north of the island," but the causal thread: how the past of a gateway to the sea and an independent path is translated into today’s population and finances.
01 · Seeing the present Nishinoomote in its numbers
In the 2020 Population Census the population has eased gently to 14,708 — about fifteen thousand. Because this city, ever since it attained city status in the middle of the Showa era, has never once undergone a merger and walked an independent path, there is no merger-derived step in its recent population movement. From the 18,866 of 2000 it has decreased gently, to 18,198 in 2005, 16,951 in 2010, 15,967 in 2015, and 14,708 in 2020.
Looking inside, the figure of an island port town raising its age appears. The share aged 65 and over rose from 25.6% in 2000 to 34.2% in 2015 and 38.1% in 2020, drawing near four in ten. The household-with-children share is 16.1% in 2020, and the crude birth rate is 6.0 per thousand in 2020. The Childcare Waitlist was zero in both 2024 and 2025. The Fiscal Capacity Index was 0.27 in fiscal 2023 — a level able to cover only a little under three-tenths of expenditure with its own tax revenue, with a large degree of reliance on the local allocation tax. The figure shows in the numbers: a port town in the north of the island where firearms were transmitted, losing population while remaining independent without a merger. Why it takes this form cannot be read without going back to the past of the island’s gateway to the sea, the island where firearms were transmitted, and the independent path.

02 · The port town in the north of the island, the island where firearms were transmitted, the gateway to the sea, the independent path — the history behind the numbers
What supports this town’s frame is the position of a port town in the north of the island, the past of the island where firearms were transmitted, the role as a gateway to the sea, and the independent path. The starting layer is the port town in the north of the island. This land lies in the north of Tanegashima of the Osumi Islands in the south of Kagoshima Prefecture, and is the island’s largest port town, originating in the castle town of the island lord’s residence. The position of a port town in the north of the island was the foundation of this town.
To this island, nearly five hundred years ago, the matchlock gun was transmitted. Aboard a ship that drifted ashore at the southern end of the island were Portuguese, who held a tube that strikes fire and looses a ball. The island lord bought it and had the island’s craftsmen make the same. The past of an island where the matchlock gun was first transmitted to Japan and first produced domestically inscribed this land’s name into history. The northern port town has, as the island’s gateway to the sea, bound the coming and going of people and goods. The path to becoming a city, too, mirrors this town. This town, ever since it attained city status in the middle of the Showa era, has never once undergone a merger. The port town in the north of the island, the island where firearms were transmitted, the gateway to the sea, and the independent path — this town’s form stands upon the past of transmission and independence that the port town, the island’s gateway to the sea, inscribed.

03 · In a port town in the north of the island where firearms were transmitted, losing population while remaining independent
What characterizes Nishinoomote is that, while it holds the past of the gateway to the sea of the island where firearms were transmitted, it is losing population, independent and without a merger. From the 18,866 of 2000 to the 14,708 of 2020, some four thousand were lost over twenty years. Even in this land that, as the island’s gateway to the sea, bound people and goods, some of the younger generation moved to the larger cities off the island, and one can read that the town’s age as a whole rose. That the share aged 65 and over drew near four in ten at 38.1% in 2020 is an expression of that.
On the other hand, the Childcare Waitlist was zero in both 2024 and 2025, the household-with-children share is 16.1% in 2020, and the crude birth rate is 6.0 per thousand in 2020. The Fiscal Capacity Index of 0.27 is a level able to cover only a little under three-tenths of expenditure with its own tax revenue, showing the large degree of reliance on the local allocation tax seen in common across island lands. The port town in the north of the island where firearms were transmitted is now losing population while remaining independent without a merger. A population decrease of some four thousand over twenty years, an aging nearing four in ten, finances thin on tax revenue alone — these look like separate numbers, yet upon the same position of an island separated from the mainland by the sea they entangle into one through the hardness of the younger generation who left to return. With a single number alone, the figure of the island port town cannot be formed.

04 · A land where a port town, the island’s gateway to the sea, bore the name of the island where firearms were transmitted
The roles Nishinoomote has held in the north of this island can be counted in several. One is that it holds the past of the island’s largest port town, in the north of Tanegashima, originating in the castle town of the island lord’s residence. Another is that it bears the character of the island where firearms were transmitted — the matchlock gun first transmitted, and first produced domestically, nearly five hundred years ago. And it holds the face of the island’s gateway to the sea, which has bound the coming and going of people and goods. The position of a port town in the north of the island has gathered here both the island lord’s castle town and the role of the gateway to the sea.
Nishinoomote is a town in which a port town, the island’s gateway to the sea, bore the name of the island where firearms were transmitted. From the position of a port town in the north of the island, to the island where firearms were transmitted, the gateway to the sea, and the independent path — the geography of "a port town in the north of Tanegashima" held the island lord’s castle town, bore the role of the island’s gateway to the sea, and set the form of the town. In this port town in the north of Tanegashima, of the Osumi Islands in the south of Kagoshima Prefecture, the island lord’s castle town, the name of the island where the matchlock gun was first transmitted, and the role of the gateway to the sea overlap into one.

05 · Atlas’s note — an island that changed the form of war now quietly loses people
Lay out Nishinoomote’s numbers and the indicators of an island port town raising its age line up: a population falling while independent, an aging rate of 38.1%, a household-with-children share of 16.1%, and a fiscal capacity of 0.27. The weight of history and the present balance of accounts I want to read apart, as separate ledgers. As the accountant I (Atlas) am, what I want to follow here is the gap that this town, while being a land that was present at a turning point of history — "the island where the matchlock gun was first transmitted to Japan" — is now quietly losing population. Nearly five hundred years ago, the tube that a single ship brought changed the form of war in this country. The island that was present at a great turn of history now, while holding that memory, sends out the younger generation to the larger cities across the sea. The reading that the weight of history and the present flow of population are separate measures explains this town’s numbers well.
Another thing I want to consider is that this town is an "island." A city of an island separated from the mainland by the sea — the younger generation who left the island for study and employment are hard to return, and the decrease of population and the aging advance quietly. Being an island gives it the role of a gateway to the sea, while at the same time constraining the coming and going of people by the sea. The advantage and disadvantage that a position brings are two sides of one coin — this view cannot be grasped while staring at a single number alone. Whether to read it off as the sign "a city in the north of the island," or to see it as "a town in which a port town, the island’s gateway to the sea, bore the name of the island where firearms were transmitted," changes with the reader’s way of living. To lay out the weight of history and the present flow of population as separate ledgers is my (Atlas’s) role, and beyond that I put no score. Nearly five hundred years ago, the tube that a single ship carried into this island in time rewrote the form of war across the country. The same island that was present at that turn now, while sending out the younger generation across the sea, quietly loses people.
