Kōka-ryū (甲賀流, literally “the Kōka School” and originally pronounced Kōka-ryū) is a school of ninjutsu. It is one of the most well-known schools of ninjutsu, along with Iga-ryū. It originated from the town of Kōka, modern Kōka City in Shiga Prefecture.

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 very uncommon for the period in question.

Members of the Koka School of shinobi 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 such as shuriken and ninjatō swords. Ninja swords were shorter than the katana worn by Samurai. The ninja used scaling hooks for climbing and supposedly used special "water-walking shoes" and the famous ninja tabi's.

The ninjas of the Kōka-ryū were divided into three classes: high ninjas (Jonin), middle ninjas (Chunin) and low ninjas (Genin).

[edit] History

Near the end of the Muromachi period, Sasaki Rokkaku of Ōmi Province, using the castle of Kannonji 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 guerilla 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 guerilla warfare used by the Kōka warriors became well-known throughout the whole country.

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".

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.

The art is currently headquartered in Philadelphia, PA. Since no one has ever seen Oyama, and this school holds none of the scrolls since they were passed on to the Ninja Museum, and Fujita Seiko died after telling reporters that he never passed on this Ryuha, these claims have not been proven and can be considered false and misleading.

[edit] Arts of the Koga Shinobi

The Koga Ninja practiced many of the same arts as their Iga counterparts. The Koga 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. Some of these arts were taught among the Samurai, but because the Koka Ninja were drafted as mercenaries or a actual army, they were taught some of what the Samurai knew as well.
