About Martyn

Sensei at North Cardiff's oldest established Martial Arts Academy

The MHKA started life in August 2002 as the Red Dragon Karate Institute. At that time, Harris sensei was the Welsh Director for the Open Circle Institute, an International Governing Body covering England, Wales, Ireland, Italy, Romania, Cyprus, France and the USA headed by world famous instructors Anthony Blades & Russell Stutely.

The Kaizenkan Karate taught at the school is a synthesis of Harris sensei's 30 year experience of karate and other martial arts. He holds black belts in Shotokan Karate and Okinawan Kempo.

The name "Kaizenkan" tranlsates as "Hall of Continuous Improvement",implying that students should strive for continuous improvement - both as martial artists and as people. The name also implies that the art itself "evolves", continuously improving to ensure that the teachings remain relevant and effective in modern society.

The style makes extensive use of pressure points and other technique enhancers along with 2 person drills in its defensive applications, making the techniques some of the most effective available.

Our founder & Chief Instructor, Martyn Harris Renshi, with over 30 years of Martial Arts experience (including over 25 years teaching) is a senior instructor and black belt examiner for the British Association for Martial Arts, a National Governing Body that also has branches worldwide. He received his 5th dan certification from this group while teaching on a convention in Devon, England in October 2011.
