Itoigawa was initially an outlying portion of Takada Domain under the control of the Matsudaira clan following the establishment of the Tokugawa shogunate. It was separated from Takeda Domain following an O-Ie Sōdō. In 1692, Arima Kiyozumi was transferred from Nobeoka Domain to Itoigawa due to mismanagement of his domains which resulted in a peasant revolt. This marked the start of Itoigawa Domain. He has transferred in 1695 to Maruoka Domain and the territory reverted to tenryō status. Itoigawa Domain was created again in 1699, this time as a 10,000 koku holding for Honda Tsukeyoshi, who had been elevated from hatamoto status. He was transferred to Iiyama Domain in 1717. The domain was then given to Matsudaira Naoyuki, grandson of Matsudaira Mitsumichi through his son Matsukata Naokata of the Echizen-Matsudaira line. His descendants ruled until the Meiji restoration. Despite the domain's location on the "Shio-no-michi", or main highway connecting the Hokuriku region with Edo and Kyoto, the domain was very small in kokudaka and suffered from numerous natural disasters, which meant that its finances were always in a crisis situation. A major uprising occurred in 1814. The sudden inflation of prices following the Perry Expedition and orders from the Tokugawa shogunate to construct coastal defence fortifications also created great unrest. The 7th daimyō of Itoigawa, Matsudaira Mochiaki became the 17thdaimyō of Fukui Domain. The domain quickly sided with the Imperial forces in the Boshin War and was renamed Kiyosaki Domain by the Meiji government. In July 1871, with the abolition of the han system, Itoigawa Domain briefly became Itoigawa Prefecture, and was merged into the newly created Niigata Prefecture. Under the new Meiji government, the final daimyō, Matsudaira Naoyasu was given the kazoku peerage title of shishaku.
As with most domains in the han system, Itoigawa Domain consisted of several discontinuous territories calculated to provide the assigned kokudaka, based on periodic cadastral surveys and projected agricultural yields.
