The district is administered out of the city hall of Mishima City.
Tagata District currently is composed of one town. The city of Atami and parts of the cities of Mishima, Izunokuni and Itō were formerly part of the district.
Tagata District was one of the original districts of Izu Province, having been separated from Suruga Province in the cadastral reform of 680 AD, and covered most of central Izu Peninsula.
Modern Tagata District was established in the July 22, 1878 cadastral reforms initiated by the Meiji government with one town (Nirayama) and 61 villages. In a round of consolidation on April 1, 1889, this was reduced to seven villages, with Nirayama reduced to village status. However, on April 4, 1896, the area of the district was greatly expanded by portions of the former Kimisawa District and Kamo District, to have two towns (Mishima and Atami) and 27 villages.
