Isahaya City, in the center of the prefecture, is surrounded by 3 seas: the Ariake Sea (Isahaya Bay), Omura Bay, and Tachibana Bay. The Isahaya Plain, enlarged by reclamation, is the prefecture's largest rice-growing area, and a stone Megane (spectacles) Bridge remains in Isahaya Park. Routes such as the Nagasaki Kaido road meet here.
