Finds of Jōmon pottery indicate that the area of Yokohama was inhabited for many thousands of years. The place name of "Yokohama" predates its more famous namesake in Kanagawa Prefecture, and can be found in Nanboku-chō period documents. The area around Yokohama was controlled by the Nambu clan from the Kamakura period and was part of Morioka Domain during the Edo period. During the post-Meiji restoration establishment of the modern municipalities system on 1 April 1889, it was proclaimed to be a village. Yokohama was elevated to town status on April 1, 1958.


Yokohama has a mayor-council form of government with a directly elected mayor and a unicameral town council of ten members. Yokohama is part of Shimokita District which, together with the city of Mutsu, contributes three members to the Aomori Prefectural Assembly. In terms of national politics, the town is part of Aomori 2nd district of the lower house of the Diet of Japan.


The economy of Yokohama was traditionally heavily dependent on commercial fishing in Mutsu Bay, primarily for sea cucumber, the local specialty, as well as sea urchin roe and scallops. With regards to agriculture, rapeseed and potato farming predominates. Electrical power production via wind farms also contributes to the local economy.


Yokohama has one public elementary school and one public middle school operated by the town government. The town does not have a high school.
