In page Sōma, Fukushima:

"

The area of present-day Sōma was part of ancient Mutsu Province, and has been settled since at least the Jōmon period. During the Edo period, the area developed as the castle town of Sōma Domain, home of the Sōma clan from the Kamakura period until the Boshin War. After the Meiji Restoration, it was organized as part of Iwaki Province. With the establishment of the modern municipalities system on April 1, 1896, the area was organized into a number of towns and villages within the districts of Namekata and Uda. In 1896, Namekata and Uda were merged to create Sōma District. The town of Nakamura was established on April 1, 1889. Nakamura was merged with seven neighbouring villages and raised to city status on March 31, 1954, becoming the city of Sōma.[citation needed]
