Before theMeiji period, the area which is now Nasushiobara was mostly uninhabited wasteland, due to lack of suitable water for agriculture.Ōtawara Domain built a number ofirrigation canals during theEdo Period, but the scale was small. However, in the Meiji period, the Nasu Canal and other agricultural development projects aimed at opening the region to farming led to rapid development, and many local place names still bear the names of various government officials of the Meiji period. With the establishment of the modern municipalities system on April 1, 1889, the villages of Karino, Takabayashi, Nabekake, Nishi-Nasuno, Higashi-Nasuno in Nasu District, and Shiobara in Shioya District were formed. A portion of Higashi-Nasuno became the town of Kuroiso in 1912. Shiobara became a town in 1919, and Nishi-Nasuno in 1932. In 1955, Kuroiso annexed Takabayashi, Nabekake and the remainder of Higashi-Nasuno, and Nishi-Nasuno annexed Kariya. Kuroiso became a city in 1970, and Shiobara was transferred to Nasu District in 1982. The modern city of Nasushiobara was established on January 1, 2005, from the merger of the former city ofKuroiso, and the towns ofNishinasuno andShiobara (both previously constituent towns ofNasu District).
