A Rich Historical Legacy
Human habitation in Kirishima stretches back to prehistoric times. The Uenohara site provides evidence of life during the Jōmon period, while the Kofun period saw the area become a stronghold for the Hayato people. During the Nara period, the region served as the center of the ancient Ōsumi Province, housing the provincial capital and temple.
For centuries, the area was under the influence of the Shimazu clan, particularly during the Edo Period. Today, visitors can still explore remnants of this history at sites like the Kokubu Castle ruins and the Ōsumi Kokubun-ji ruins.

Economy: From Agriculture to 'Technopolis'
Kirishima maintains a diverse and resilient economy. Historically, agriculture has been a cornerstone of local life. The city is known for producing a wide variety of goods, including strawberries, tomatoes, tea, and eel. Notably, local leaf tobacco production has a history dating back to 1606, though its scale has decreased in recent years.
In a modern twist, the former Kokubu-Hayato area has been designated as a "Technopolis"—a term used to describe a high-tech industrial hub. Leveraging its proximity to Kagoshima Airport and major expressways, the city has attracted global giants like Sony and Kyocera, who operate large-scale production plants in the region.
Transportation and Connectivity
Kirishima is exceptionally well-connected, making it an essential transit point in southern Kyushu. The city is home to Kagoshima Airport, the primary airport for the prefecture, located in the Mizobe area. For rail travelers, the city is served by the JR Kyushu Nippō Main Line and the JR Hisatsu Line, the latter of which terminates in the area.
