The Evolution of Satsuma's Boundaries
The modern layout of the Satsuma district is the result of two major waves of consolidation that occurred in the mid-2000s. These mergers significantly altered the population density and geographic footprint of the region.
The Formation of Satsumasendai
On October 12, 2004, a massive merger took place to create the new city of Satsumasendai. This process involved the integration of the old city of Sendai, the towns of Hiwaki, Iriki, Kedōin, and Tōgō, as well as the villages of Kamikoshiki, Kashima, Sato, and Shimokoshiki. This transition dramatically reduced the overall size and population of the remaining Satsuma district.
Following this merger, the district's population fell to 26,587 people, covering an area of 303.43 km². This resulted in a population density of approximately 87.62 persons per square kilometer.
The Establishment of the New Satsuma Town
Shortly after the creation of Satsumasendai, another consolidation occurred on March 22, 2005. The towns of Satsuma, Miyanojō, and Tsuruda merged to form the current town of Satsuma. This merger finalized the district's current status as a single-town entity.
