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.
