As with all of Kōchi Prefecture, the area of Hidaka was part of ancient Tosa Province. During the Edo period, the area was part of the holdings of Tosa Domain ruled by the Yamauchi clan from their seat at Kōchi Castle. The villages of Kusaka (日下村) and Nōzu (能津村) were established with the creation of the modern municipalities system on October 1, 1889. The two villages merged, together with a portion of the village of Kamo (加茂村) on February 10, 1955 to form the village of Hidaka.

Hidaka has a mayor-council form of government with a directly elected mayor and a unicameral village council of ten members. Hidaka, together with the municipalities of Sakawa and Ochi, contributes one member to the Kōchi Prefectural Assembly. In terms of national politics, the village is part of Kōchi 2nd district of the lower house of the Diet of Japan.

Hidaka's economy is centered on agriculture, notably growing cherry tomatoes, and the production of imo kenpi.

Hidaka has three public elementary schools and two public middle schools operated by the village government. The village does not have a high school. The Kōchi Prefecture Board of Education operates one special education school for the handicapped.
