Yayoi period
Archaeological examination of several sites around Wakō has revealed the remains of a number of villages in the area, including a large amount of Jōmon period pottery, stone tools and other remains. Signs of early rice cultivation coinciding with the Yayoi period as well as quantities of Yayoi period pottery and implements have also been found. The area of modern Wakō developed from the Muromachi period as Shirako-juku, a post station on the Kawagoe-kaidō highway.
