Geography and Climate
Nakatsu occupies a diverse geographical position, facing the Gulf of Suō on the Seto Inland Sea to the northeast.

This wide stretch of flat, agricultural land begins at the mouth of the Yamakuni River and extends to Mount Hiko, making it the largest agricultural area in the prefecture.
The city's skyline is dominated by Mount Hachimen (八面山), which translates to "eight-faced mountain." This name stems from the mountain's appearance, which remains remarkably consistent regardless of the angle from which it is viewed. It stands as a central symbol of the city, surrounded by various local legends.

The region experiences a humid subtropical climate (Köppen classification Cfa), characterized by hot summers and cool winters. The average annual temperature is approximately 16.3 °C (61.3 °F). While precipitation occurs throughout the year, June is typically the wettest month. Summers can be quite warm, with average August temperatures around 27.9 °C (82.2 °F), while winters see averages around 5.8 °C (42.4 °F) in January.
A Rich Historical Legacy
The history of Nakatsu is deeply intertwined with the ancient Buzen Province. During the Sengoku period (a period of warring states in Japan), Kuroda Yoshitaka (Josui) constructed Nakatsu Castle as a flatland castle near the Yamaguni River in 1587. During the subsequent Edo period, the area served as the center of the 100,000 koku Nakatsu Domain, governed by the Okudaira clan.
Following the Meiji Restoration, the modern municipality system was established, and Nakatsu was officially raised to city status on April 20, 1929. Over the decades, the city has grown through various mergers, including the incorporation of the towns of Hon'yabakei, Yabakei, and Yamakuni, as well as the village of Sankō in 2005.
Economy and Education
As the third most populous city in Ōita Prefecture, Nakatsu maintains strong economic ties with the Kitakyushu area of Fukuoka Prefecture. The city has become a significant center for the automotive industry, especially after Daihatsu Auto Body Co., Ltd. moved its head office and factory to the area in 2004. Beyond automobiles, the local economy is supported by industries such as ceramics, semiconductors, and plastics.
Education is well-supported within the city, featuring 21 public elementary schools, ten public junior high schools, and four public high schools operated by the Ōita Prefectural Board of Education, alongside one private high school and Higashikyushu Junior College.
