What is Bun Bu Toshu Kempo? 

Bun Bu Toshu Kempo is a walk back in time to the old school practices and intent of original Okinawan martial arts. Utilising old school practices, modern understanding of biomechanics, Bun Bu Toshu Kempo offers a dynamic functional system of martial arts focused on developing realistic self defence skills via two-person application practices. 

Ancient practices, Budo culture and a strong sense of community is the ethos of the Koryukan.

Our Services

The Koryukan provides classes for students and instructors of all levels in our martial arts system of Toshu Kempo. Although we teach a complete system of "old school" martial arts, the core or Gokui of our system will resonate with any martial arts program focused on delivering functional self-defence skills. Toshu Kempo includes effective Striking drills, Break-falling and Throws, Joint Locks, Choking methods and Grappling. 

Juniors Program - The Koryukan offers classes specific to students  5yrs - 11yrs via our Juniors class. Students are taught effective self-defence skills, community values and sportsmanship. 

Kobudo - training with traditional weapons offers a unique way of preserving ancient practices, enhancing the development of co-ordination and providing situational awareness. All students are invited to practice kobudo from Yellow belt onward and it is mandatory for all Black Belt students. Our Kobudo curriculum includes the use of Bo, Sai, Tuifa, Nunchaku, Kama, Eku, Tanbo and Knife via kata and two-person exercises.
