Minnesota Kōburyū Kōbukai

About Our Style

Kōburyū is the name of our karate and kobudō style. Karate is the “empty hand” style of martial arts known for punching, kicking and throws. Kobudō is training with the weapons of ancient Okinawa, including the bō (six foot staff), sai, nunchaku and more. Kōburyū is firmly based in traditional karate, but with an emphasis on practical self-defense and natural use of the body. to create power. Most students study both karatedō and kobudō, but beginners are expected to start with karatedō.  If you already have rank in another martial arts style, it is possible to pursue your interest in kobudō without pressure to change your empty-handed style. Students will progress according to their own ability, interest and commitment. Karatedō and kobudō have separate training, advancement, and test fees. 

About the Dōjō

Okinawa kōburyū karatedō and kobudō sessions meet at the Martial Art Fitness Centers, Inc. (MACFI).
