TSG Systems & Styles

The following systems and styles are taught in the TSG INTERNATIONAL BUDO ASSOCIATION


TSG-Combat Karate is a modern and realistic system that has been developed by Soke David C. Cook 10th Dan. Soke Cook has used his over 45 years experience of teaching Budo to develop this system.

The TSG-Combat Karate system is built around 12 newly developed Kata that contain realistic and effective fighting combinations. These combinations are suitable for various forms of fighting and also self-defense.

The system includes mainly standing fighting and some Throws and Takedowns, Control Positions and even some Joint Locks and Chokes

Unlike most traditional styles these Kata are always practiced with an Uke (training partner). The system is designed to be suitable for a large range of students: children and adults, male or female, people training for fitness and as a hobby, and also serious students of Budo.


The TSG-Mix Fight is a style Soke Cook started developing in 1995, it is a system that contains a wide range of fighting techniques including striking, kicking, throws and takedowns and also grappling.

The Basics, Fighting Drills and Fighting Combinations contain most aspects of mixed fighting.

The throws have been chosen for students who prefer standing fighting. The students learn to punch and kick first and if necessary take their opponent down to the floor and “finish the fight” with some suitable techniques.

Just as with the kicks and punches, a couple of new throws are taught for each grade and the same applies to the joint locks and strangles & chokes. The basic control positions are spread out through the first couple of grades.



Kyokushin Karate is the style that was developed by the legendary Sosai Mas Oyama 10th Dan. Kyokushin Karate is a system that is famous for its tough fighters. It was the first Karate system that incorporated low kicks as a main part of the system.
Soke Cook 10th Dan, spent fourteen years with Sosai Mas. Oyama's Kyokushin Organisation. He is the author of the popular book based on the Kyokushin Style,  “Power Karate” and a recently revised edition TSG-Kyokushin Karate.

In 1977 he was one of the first two Europeans to complete the 50 Man Kumite. (Fifty rounds of full contact Kyokushin fighting, two minutes each, without any rest periods).

At one time he was a Kyokushin Branch Chief and the Chairman of the Swedish Karate Kyokushinkai.

In 2010 Soke Cook developed and added 4 Fighting Combinations to each of the grades from 10th Kyu to 3rd Dan in the TSG-Kyokushin Syllabus, a total of 52 fighting combinations, in order to improve the fighting knowledge of the students. Soke Cook still teaches fighting techniques at Kyokushin Karate seminars.


TSG-Ashihara International Karate is the system that was originally developed by Kancho Hideyuki Ashihara. In 1987 Soke Cook visited Kancho Ashihara in Japan, because he had heard that Kancho Ashihara had started to break with the traditional way of teaching Karate in Japan, and this seemed like it might be an interesting path to follow.

On his return from Japan, he started promoting the Ashihara Style in Europe. Although he thought that Ashihara Karate was a step in the right direction, he felt that there was still room for improvement, so he continued to develop the system, adding fighting combinations for every grade and developing the Kata so that they could always be practiced with a partner (Uke).

This variation of the system was renamed Ashihara International Karate. Soke Cook’s path from a traditional Karate style, Kyokushin Karate, to a less traditional style, Ashihara Karate, to a more modern style, Ashihara International, has one thing in common - application (Bunkai).

When he first came into contact with Soke Ruiz 10th Dan, in the USA in 1982 one of the things that impressed him most was Soke Ruiz’s knowledge of Kata Bunkai. Having trained Kyokushin Karate where Bunkai of Kata was not a well developed concept, he was impressed by the ability of Soke Ruiz to go back to the roots of the Kyokushin Kata and demonstrate the original Bunkai of the Kata.

Therefore when Soke Cook developed the Ashihara International Karate from the Japanese Ashihara Karate, he was determined that all the techniques of every Kata should be performed with a training partner (Uke). This made the Bunkai automatic because the students learnt the Kata in the Bunkai form and this is thanks to the influence of Soke Ruiz.
