Sōma was located in southern Tsugaru Peninsula, on the border of Akita Prefecture. The area was part of Hirosaki Domain during the Edo period. After the Meiji Restoration, Sōma Village was created in 1889.
On February 1, 2006, Sōma, along with the neighboring town of Iwaki (also from Nakatsugaru District), was merged into the expanded city of Hirosaki, and thus no longer exists as an independent municipality.
