Key Facts
- Merger Date: January 1, 2005
- Merged Entities: Notsuharu and the town of Saganoseki
- Resulting Municipality: The expanded city of Ōita
- Original District: Saganoseki was part of the Kitaamabe District
The Administrative Transition
Before the merger, the area comprised distinct local jurisdictions. Notsuharu and the town of Saganoseki—which was situated within the Kitaamabe District—operated as separate entities. A municipal merger is a process where multiple local governments combine to form a single, larger administrative unit, often intended to streamline services and improve regional efficiency.
On the first day of 2005, these territories were officially integrated into the city of Ōita. This move resulted in the expansion of Ōita's borders and its administrative responsibilities, absorbing the populations and resources of the former Notsuharu and Saganoseki areas.
