The area of Kanra District was formerly part of Kōzuke Province, and appears in Nara period records, such as the 711 AD Shoku Nihongi as Kanra gun (甘良郡?), whose etymology indicates that it was an area settled by large numbers of people from the Korean peninsula. Per a census conducted at the end of the Edo period, the area was divided into three towns and 79 villages administered as tenryō directly by the Tokugawa shogunate, 21 villages under the control of Nanokaichi Domain and 32 villages under the control of Obata Domain. Two more villages were under the shared control of Obata Domain and the Tokugawa shogunate. On December 7, 1878, the area was divided into Minamikanra District (which subsequently became Tano District, and Kitakanra District (present-day Kanra District). With the establishment of the municipality system on April 1, 1889 the area was organized into five towns (Tomioka, Ichinomiya, Myōgi, Shimonita and Fukushima) and 18 villages
