Fukuoka

In the most recent Population Census the population is about 1.61 million (1,612,392 in 2020). Over the five years from 1,538,681 in 2015 it added more than seventy thousand. Even among designated cities, where a million residents are not unusual, few are growing at this pace.

What is worth seeing here is that the number of children, too, is rising. Those under 15 rose from 199,923 (2015) to 204,973 (2020), about five thousand more. Designated cities whose absolute number of children is rising are not many, even across the whole country. Over the same five years the share aged 65 and over rose only slightly, from 20.3% to 21.0%, placing it on the gentle side of aging among designated cities. The published residential land price is around 88,000 yen per m². The Fiscal Capacity Index is 0.87 — a structure in which part of standard expenditure is filled through the local allocation tax. Households with children make up 17.4% (2020), and the childcare waitlist moved slightly, from 0 children (2024) to 4 (2025). But these are averages for a city of 1.6 million. The municipal area is divided into seven wards — Higashi, Hakata, Chuo, Minami, Nishi, Jonan and Sawara — differing greatly in character from the central Tenjin and Hakata to suburban residential areas. The gaps between wards are flattened out and do not appear in this single figure. Why the city takes this shape cannot be read without going back to the two origins of a samurai town and a merchant town.

Fukuoka’s skeleton is the history of two lands of differing character, divided by a single river, bound into one city. Divided by the Naka River, Hakata to the east and Fukuoka to the west were originally towns of separate origin.

Hakata, to the east, is a port town from ancient times. As a window for exchange with the continent, the Korokan guesthouse was placed here to receive those who crossed over, and in the medieval period it became an international trading port that flourished through commerce. A town of merchants connected to the continent across the sea — this is Hakata’s origin. Fukuoka, to the west, began as a castle town. In 1600, Kuroda Nagamasa, granted the whole province of Chikuzen for his service at the Battle of Sekigahara, built a castle to the west of Hakata and named the place Fukuoka, after Bizen Fukuoka, a place tied to the Kuroda house. Divided by the Naka River, with the merchants’ Hakata to the east and the samurai’s Fukuoka to the west — the composition of two towns of differing character standing side by side was born here.

From the Meiji era on, these two towns grew as a single city. Through hosting the 1910 joint exhibition of the eight prefectures of Kyushu and Okinawa, attracting Kyushu Imperial University, and transforming into a modern city of consumption from the 1920s into the 1930s, Fukuoka became a metropolis holding the largest population in Kyushu. And one more thing keeps deciding this city’s fate: geography. Across the Genkai Sea it is near the continent, only about two hundred kilometers in a straight line to Busan. From the ancient Korokan to the modern airport and port, the location of a window to Asia has carried people and goods into this city across eras. A samurai town and a merchant town, and nearness to Asia — the roots of Fukuoka being a city that keeps growing can be traced down to these three foundations.

What characterizes Fukuoka is that while the total population rose by seventy thousand in five years, the number of children rose too, by five thousand. That appears in the figures for living infrastructure in a form opposite to the consolidations common in regional cities that lost large populations. Households with children make up 17.4% (2020) — somewhat low among designated cities, but this is also the flip side of a heavy inflow of single young people and students.

The childcare waitlist moved slightly, from 0 children (2024) to 4 (2025). In a city where children keep increasing and young households keep flowing in, holding the waitlist at zero is not easy. The figure of 4 indicates a moment in which demand slightly exceeded supply, and can be read as a number on the underside of an origin in which the absolute number of children keeps rising. Even the same “the waitlist moves” differs entirely in its underlying circumstances between an increase in a city where children fall and an increase in a city that keeps growing. Children increase, the population grows, and childcare demand swells accordingly — these are not scattered movements but phenomena branching from a single structure: a city of continued inflow. And this too is an average across seven wards: between central wards of intense inflow and settled suburban wards, the circumstances of children and childcare are not the same. A number, on its own, does not fix its own meaning.

Many functions of differing origin are folded into Fukuoka. One is the area east of the Naka River, with its origin in the ancient port town of Hakata, still holding Hakata Station as the gateway by land and the Port of Hakata as the gateway by sea, remaining a node in the flow of goods and people. Another is the center around Tenjin, west of the Naka River, with its origin in the castle town of Fukuoka, now the business and commercial concentration of Kyushu. And Fukuoka Airport, near the center, carries the window to Asia by air, continuing into the present the “nearness to the continent” that has held since the ancient Korokan.

Fukuoka became a designated city in 1972, and the city holds, on its own, administrative authority as the hub of Kyushu. From an ancient port town to a castle town, and on to Kyushu’s largest city — on the landform of a bay and a river open to Asia, different functions have been swapped in, era by era. The Korokan, the Kuroda castle and the modern airport all rest, in the end, on the same land that faces the continent. Nearness across the sea summoned the Korokan in antiquity, gathered merchants in the medieval period, drew in the airport in modern times, and still carries people and goods into this capital — a single location has, over a thousand years, kept growing Fukuoka.
