==History== The beginnings of the Kōga-ryū may be traced to near the end of the Muromachi period. While the district of Kōga, in Ōmi Province, was under the jurisdiction of the Rokkaku clan, it was a kind of autonomous municipality, composed of localized unions called sō (). The Kōka confederacy called itself the Kōka-gun Chūsō (甲賀郡中惣, "General Assembly of Kōka District"). All important decisions in the municipality were made by a majority vote from the union representatives. This kind of system was uncommon for the period in question.
