History

The area of present-day Ōhira was part of ancient Mutsu Province, and has been settled since at least the Jōmon period by the Emishi people. Per the Shoku Nihongi, following an earthquake in the year 715 AD, a large number of people migrated to this area from the southern Kantō region, forming numerous fortified settlements. During the Sengoku period, the area was contested by various samurai clans before the area came under the control of the Date clan of Sendai Domain during the Edo period, under the Tokugawa shogunate.

The village of Ōhira was created within Kurokawa District, Miyagi Prefecture after the Meiji restoration on April 1, 1889 with the establishment of the modern municipalities system.

Ōhira has a mayor-council form of government with a directly elected mayor and a unicameral village of 11 members. Ōhira, together with the rest of Kurokawa District and the city of Tomiya collectively contributes two seats to the Miyagi Prefectural legislature. In terms of national politics, the village is part of Miyagi 4th district of the lower house of the Diet of Japan.
