Kōga-ryū

Kōka-ryū (甲賀流, "School of Kōka" (ryū means school or style) is a school of ninjutsu. It originated from the region of Kōka (modern Kōka City in Shiga Prefecture). Members of the Koka school of shinobi (ninja) were trained in disguise, escape, concealment, explosives, medicines and poisons, they were trained in techniques of unarmed combat and in the use of various weapons.

History

The beginnings of the Kōka-ryū may be traced to near the end of the Muromachi period. While the town of Kōka was under the jurisdiction of the Rokkaku (lit. "hexagon") clan, it was a kind of autonomous municipality composed of peasant unions, then called sō (惣). 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.

Sasaki Rokkaku of Ōmi Province, using Kannonji Castle as a base, started to steadily build up military might. He made light of commands from the Ashikaga shogunate, and eventually began to ignore the shogunate altogether. In 1487, General Ashikaga Yoshihisa brought with him an army to stamp out this rebellion, and a battle between Ashikaga and Rokkaku’s camps ensued. Ashikaga mobilized daimyo from several provinces in the castle of Kannonji, the headquarters of the Rokkaku; as a result, Rokkaku Masayori and Rokkaku Takayori (Masayori's son) were forced to flee to the castle of Kōka. The factual accuracy of their escape is debated and it is likely that they gave up the town to avoid a direct confrontation instead.

Ashikaga then moved his base to Anshiyoji of Kurita District and attacked the castle of Kōka. Kōka fell, but the Rokkaku duo escaped and ordered the Kōka warriors who followed them to mount a heavy resistance against Ashikaga using guerrilla warfare. Exploiting their geographical advantage in the mountains, the Kōka warriors launched a wide range of surprise attacks against Ashikaga’s forces, and tormented them by using fire and smoke on Ashikaga’s camp during the night. The guerrilla warfare prevented a final showdown, until Ashikaga died in battle in 1489, ending the three-year conflict and sparing the lives of the Rokkaku duo.

The elusive and effective guerrilla warfare used by the Kōka warriors became well-known throughout the whole country. This also marked the first time that the ninja of Kōka were drafted as a regular army by their lord. Previously, they were only mercenaries and it was not uncommon to have warriors from Kōka on both sides of a battle. As a result of this victory, the local samurai in the 53 families who participated in this battle were called "the 53 families of Kōka".

Arts of the Kōka

The Kōka ninja practiced similar arts as their Iga counterparts. The Kōka had separated the arts so they could practice solely on what was needed for certain situations. Instead of mixing all the teachings, separating them allowed them to focus, yet they used them together in a lethal combination. Kage Ryu is a so called decendent of Koga Ryu. Two teachers Sensei Titus Jansen & Sensei Arie Van Den Akker both trained under Ashida Kim who all represent the Black Dragon society. Both claim to be experts at the highest level in Koga Ryu Ninjutsu or as they spell it ninjitsu.
