History

Historic map of Naka District

Naka District was one of the four subdivisions of Sagami Province established by the later Hōjō clan of Odawara during the Sengoku period. In the Edo period, it was nominally part of Odawara Domain, although large portions were tenryō territory controlled by the shōgun in Edo through various hatamoto.

Timeline

edit

After the Meiji Restoration and with the establishment of the district system in 1878, the territory came under the control of Ōsumi District (大住郡, Ōsumi-gun) and Yurugi District (淘綾郡, Yurugi-gun). On March 26, 1896, these two districts were joined to form the modern Naka District, which initially consisted of five towns and 23 villages. Hiratsuka was elevated to city status in 1932, followed by Hadano in 1955 and Isehara in 1971.
