The area of Nishinoomote was part of ancient Tane Province, which was abolished in 824 and incorporated into Ōsumi Province. Tanegashima became a part of Shimazu shōen in 1140. During the Edo Period, the area was part of the holdings of Satsuma Domain. Sugarcane was first cultivated in 1824. Kitatane Village was established on April 1, 1889 with the establishment of the modern municipalites system. It was elevated to town status on April 1, 1926 and renamed Nishinoomote. Towards the end of World War II, the town was garrisoned by a 12,000-man force from the Imperial Japanese Army and was thus subjected to bombing by the United States Navy in 1945. It was elevated to city status on October 1, 1958.
