The area around Ōma was inhabited by the Emishi people until the historical period. During the Edo period, it was controlled by the Nambu clan of Morioka Domain. During the post-Meiji restoration establishment of the modern municipalities system on 1 April 1889, Ōoku Village was proclaimed from the merger of Ōma hamlet with neighboring Okudo hamlet. It was renamed Ōma Town on 3 November 1942.
Ōma has been a popular location setting for movies and television dramas. It was the setting for the 1983 movie Gyōei no mure (魚影の群れ) starring Ken Ogata. In 2000, Ōma was the setting for an NHK television series Watashi no Aoi Sora (私の青空) starring Tabata Tomoko. This was followed by another fictional series Maguro (マグロ) on TV Asahi starring Tetsuya Watari in 2007.
Ōma has a mayor-council form of government with a directly elected mayor and a unicameral town council of ten members. Ōma 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 city is part of Aomori 1st district of the lower house of the Diet of Japan.
The economy of Ōma was traditionally heavily dependent on commercial fishing. The town was famous for having the "black diamond" of tuna, which are caught in the traditional manner by hand in two-person boats, and sold under the "Ōma" registered brand. One Ōma tuna was sold at a record-high 333.6 million yen in January 2019.[7] Other seafood products include sea urchin roe, konbu and squid.[8]
The town is the site of a nuclear power plant, the Ōma Nuclear Power Plant, which will be unique in its use of MOX fuel when it comes on line.[9]
