Kata and Bunkai

This is a list of the tradition Shidokan kata practiced at Grand River Karate.


The bunkai and oyo bunkai kata are also practiced with attackers. One student designated as the defender is positioned in the middle of a group of other students posing as attackers and performs the kata against/in partnership with the attackers. Each student is required to know their position's attack routine. When the kata is completed, the students rotate to a new position in the group, with a new person in the middle.


Students are required to know and perform all the positions. The bunkai and oyo bunkai have been handed down to and refined by Seikichi Iha Sensei.
