Reading Oita Prefecture through the data
Certified public accountant / editor — reading the bigger picture by tying public data together.
The hot springs are among the world’s finest. Yet the employment figure runs 1.7σ below the line of its underlying power.
Oita’s stability is supported by a depth of medicine that does not rely on any single indicator, but behind it lies employment that falls short of the underlying power. From here, groundwork for an industrial base stands alongside two weights—population dynamics and a coastal earthquake. The weakness of the hot-spring prefecture is not a shortfall but a missed catch.
Past・How it got here
The prefecture of rising steam
Beppu Onsen is a hot-spring resort with one of the world’s largest discharge volumes, where one can tour the “Beppu Hatto”—eight hot-spring areas of differing water qualities. With attractions such as the “hells tour,” the hot water itself is a tourism resource that symbolizes the prefecture. Oita is a prefecture where hot-spring resources stand out, with Oita City as its capital. The core of tourism lies in Beppu and Yufuin.
Hot water that keeps welling up from the land—that resource forms the face of the prefecture called Oita. Yet behind that face, the numbers hold a weakness in the form of “not a shortfall, but a missed catch.”
The chart below renders, as a single line, the longest story available on the time-series side. The hot-spring prefecture of Beppu and Yufuin has kept holding half a century of hot water welling up from the land and tourism—that persistence shows up in the slope of the long-term trend. What I (Atlas) am careful about is that the stability visible in the length of the line and the present missed catch—where employment falls below the line of its underlying power—ought to be read on separate scales. I treat the direction of history and the present phase separately—the reading that the hot-spring prefecture’s weakness is not a shortfall but a missed catch does not appear on the long-term line.
The hot water keeps welling up from the land. Yet Oita’s weakness is not a shortfall of underlying power, but a missed catch.
