In this town’s port, the trading posts of distant lands across the sea once stood in a row. For about thirty-odd years before the completion of national seclusion, this was Japan’s one and only trading port receiving the ships of a certain country. The trading post of another country was also placed here, and missionaries called too; this land was also a castle town that a single family ruled from the Warring States period to the Meiji era. This castle town of the port where the southern-barbarian trading posts stood in a row, in a city area binding three islands, has now quietly lost population. Hirado’s numbers are the record of a town in which the past of an international trading port and a castle town is inscribed.
A city consisting of Hirado Island and other islands at the northwest tip of Nagasaki Prefecture. Because this city was established in 2005 when the castle-town port city became one anew with the towns and village of three surrounding islands, the step in population for the city area appears between 2000 and 2005, when the merger is reflected in the Census. Seen for the castle-town port city alone, the population was 23,900 in 2000; in the merged city area it was 38,389 in 2005, and from there it has fallen to the 29,365 of 2020. What I (Atlas) want to read here is not the sign "an island city of the prefecture’s northwest," but the causal thread: how the past of an international trading port and a castle town is translated into today’s population and finances.
01 · Seeing the present Hirado in its numbers
In the latest Population Census the population is about 29,000 (29,365 in 2020). Because this city was established in 2005 when the castle-town port city became one anew with the towns and village of three surrounding islands, the step in population for the city area appears between 2000 and 2005, when the merger is reflected in the Census. Seen for the castle-town port city alone, the population was 23,900 in 2000; in the merged city area it was 38,389 in 2005, 34,905 in 2010, 31,920 in 2015 and 29,365 in 2020, falling.
Looking inside, the figure of a castle-town port city open to the sea appears. The share aged 65 and over rose from 37.3% in 2015 to 41.4% in 2020, passing four in ten. The household-with-children share is 16.8% in 2020, and the Childcare Waitlist was zero in both 2024 and 2025. The Fiscal Capacity Index was 0.24 in fiscal 2023 — a level able to cover only a little over two-tenths of expenditure with its own tax revenue, with a large degree of reliance on the local allocation tax. A castle town of the port where the southern-barbarian trading posts once stood in a row proceeds, after the merger, toward aging past four in ten. Why this contrast arose cannot be read without going back to the past of the port, the trading posts and the castle town.

02 · The castle town a family ruled, the port where the southern-barbarian trading posts stood in a row, the move under seclusion, a merger of three islands — the history behind the numbers
Hirado’s past is made of three layers piled in the order of the ages. The old layer is the castle town and the port. This land was a castle town that a single family ruled from the Warring States period to the Meiji era, and to its port came the ships of the lands across the sea. In 1550 a missionary also called. The family’s castle town and the port open to the sea are this land’s oldest foundation.
At that port, the southern-barbarian trading posts stood in a row. In 1609 the ships of a certain country entered port, and for about thirty-odd years until the move to Nagasaki’s Dejima in 1641, this port bustled as Japan’s one and only trading port receiving that country’s ships. The trading post of another country was also placed here from 1613 to 1623, and this became the center of the southern-barbarian trade. But with the completion of seclusion the trading posts moved to Nagasaki, and the port’s bustle receded. The newest layer is the path to becoming a city. In 2005 the castle-town port city became one anew with the towns and village of three surrounding islands. The castle town the family ruled, the southern-barbarian trading posts, the move under seclusion, and the merger of three islands — beyond piling these four layers in order of age, the present city area lies.

03 · In the castle town of the port where the southern-barbarian trading posts stood in a row, losing population after the merger
What characterizes Hirado is that, while it holds the past of an international trading port and a castle town, it is losing population after the merger. The 23,900 of 2000, seen for the castle-town port city alone, became 38,389 in 2005 in a city area binding three islands, and from there to the 29,365 of 2020, over nine thousand were lost over fifteen years. Even in this port where the southern-barbarian trading posts once stood in a row, after the center of trade moved to Nagasaki with seclusion it became a land of islands centered on fishery and agriculture, and one can read that some of the younger generation moved toward the larger cities and the town’s age as a whole rose. That the share aged 65 and over passed four in ten at 41.4% in 2020 is an expression of that.
On the other hand, the Childcare Waitlist was zero in both 2024 and 2025, and the household-with-children share is 16.8% in 2020. The Fiscal Capacity Index of 0.24 is a level able to cover only a little over two-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 population fell after the merger, the aging passed four in ten, and the body of the finances is not thick on tax revenue alone. What combination of numbers the castle-town port from which the center of trade departed now settles into — that comes into view only when population, age and finances are laid out on a single sheet.

04 · A castle town of a port open to the sea became the center of the southern-barbarian trade
The functions Hirado holds are not one. It has the face of a castle-town port, a castle town that a single family ruled from the Warring States period to the Meiji era, to whose port came the ships of the lands across the sea. It also has the face of an international trading port, which for about thirty-odd years before the completion of seclusion became Japan’s one and only trading port receiving a certain country’s ships, where the trading post of another country was also placed and which became the center of the southern-barbarian trade. The landform and position of an island open to the sea at the northwest tip of Kyushu called the castle town and called the port receiving the ships of the lands across the sea.
A castle town of a port open to the sea became the center of the southern-barbarian trade — that is the town Hirado is. From the family’s castle town, to the southern-barbarian trading posts, the move under seclusion, and the merger of three islands, what set the skeleton was the geography of "an island open to the sea at the northwest tip of Kyushu." Upon the position of the northwest tip of Nagasaki Prefecture, the family’s castle town and an international trading port are folded together. For some thirty-odd years before seclusion, the world came and went here.

05 · Atlas’s note — in a town where the southern-barbarian trading posts stood in a row, a brilliant past and quiet numbers overlap
Lay out Hirado’s numbers and the indicators of a castle-town port city open to the sea line up: a population falling after the merger, an aging rate of 41.4%, a household-with-children share of 16.8%, and a fiscal capacity of 0.24. But when I (Atlas), as a certified public accountant, read these, what catches me most is the singularity of this town’s past — that "before the completion of seclusion, it was an international trading port, Japan’s one and only receiving a certain country’s ships." For about thirty-odd years from 1609 to 1641, the southern-barbarian trading posts stood in a row at this port, the trading post of another country was also placed, and the wealth and culture of the lands across the sea flowed into this land. But with seclusion, that center of trade moved to Nagasaki. The port function that called in wealth receded by a single decree of governance — this course explains this town’s afterward well.
Another thing I want to consider is the thinness of the tax revenue and the height of the age — a Fiscal Capacity Index of 0.24 and an aging rate of 41.4%. Even the castle-town port that was once the center of international trade, after the trade function departed and it became a city area binding islands, has, as a land centered on fishery and agriculture, lost population and advanced its aging to four in ten.
The brilliant past of the thirty-odd years when the world came and went, and the quiet numbers of an island land centered on fishery and agriculture, overlap in the same single town at the northwest tip of Kyushu. Whether to visit this town as a castle-town port where the southern-barbarian trade flourished, or to view it as a land of islands where fishery and agriculture still continue, will divide the image of Hirado. The brilliance of the thirty-odd years when the world came and went, and the quiet of an island land where fishery and agriculture continue, are folded together in the same single town at the northwest tip of Kyushu.
