The Hokubei Shotokan Kuro Obi Kai is a nonprofit karate program based heavily on Shotokan-ryu with some influence from Goju-ryu and Hayashi-Ha. Our program focuses on practical self-defense and study of kata. We host kid's classes, adult classes and specialized Kobudo classes at the Coffman YMCA in Springboro, Ohio, just 15-20 minutes south of Downtown Dayton through I-75.
