津軽半島
Goshogawara occupies two discontinuous areas on Tsugaru Peninsula in western Aomori Prefecture. The Iwaki River flows through the city. The larger section is landlocked, and is in the middle of the peninsula. It contains the original town of Goshogawara, and is the population centre of the city. The smaller exclave to the north is on the Sea of Japan coast. Parts of the city are within the borders of the Tsugaru Quasi-National Park.
