Kashiwagi-jinja Shrine, called Wakamiya Hachimangu until the Edo era, has long been revered by the local people for the influential local rulers of the Kashiwagi area including Yamanaka, Minobe, and Ban clans to strengthen their spiritual ties.
It is known that Koka warriors formed an alliance with one another to conduct independent self-governance in medieval Koka. Kashiwagi-jinja Shrine is thought to have served as a place of unity and center of activity for these Koka warriors.
