The area of present-day Kashiwazaki was part of ancient Echigo Province and developed as a post station on the Hokuriku-dō highway. Under the Tokugawa shogunate of Edo period Japan, parts of what is now Kashiwazaki were under the control of Shiiya Domain, a minor fudai feudal domain ruled by a junior branch of the Hori clan,[4] while other parts were tenryō territory under direct control of the shogunate, or were exclaves of Kuwana Domain (Ise Province), Kaminoyama Domain (Mutsu Province), Nagaoka Domain (Echigo Province) or Yoita Domain (Echigo Province). Pre-modern Kashiwazaki was located within the holdings of Kuwana Domain. The modern town of Kashiwazaki was established on April 1, 1889, within Kariwa District, Niigata with the establishment of the municipalities system. During the Meiji period, the discovery of petroleum in the area led to an economic boom and increase in population. Kashiwazaki was elevated to city status on 1 July 1940. (It was the fifth city created within Niigata Prefecture).

On November 1, 1968, Kashiwaza absorbed the village of Kurohime, followed by the town of Kitajō on May 1, 1971 (both from Kariwa District). The city annexed part of the town of Kakizaki (from Nakakubiki District) on April 1, 1989 and the towns of Nishiyama and Takayanagi (both from Kariwa District) on May 1, 2005.
