Shibukawa is located within traditional Kōzuke Province. During the Edo period, the area of present-day Shibukawa prospered from its location on the Mikuni Kaidō highway connecting Takasaki with Niigata. Post stations within the borders of modern Shibukawa were Shibukawa-shuku, Kanai-shuku, Kitamoku-shuku and Yokobori-shuku.
