Sotogahama is in Higashitsugaru District of Aomori Prefecture, and consists of two discontinuous geographic areas in northern Tsugaru Peninsula.

The larger area is in the south, and consists of the former town of Kanita with a coastline on Mutsu Bay, and the former village of Tairadate in the centre of northern Tsugaru Peninsula.

[3] Per Japanese census data,[5] the population of Sotogahama has decreased by more than half over the past 60 years and is now considerably less than it was a century ago.

The Tsugaru Peninsula has been inhabited since Japanese Paleolithic times, and some of the world's oldest pottery has been discovered at the Odai Yamamoto I site.

During the post-Meiji restoration establishment of the modern municipalities system on April 1, 1889 Minmaya, Kanita and Tairadate villages were separated from Imabetsu.
