About US

The Internet has created new opportunities and ways for learning.

I know from my travels all over the world that there is a lot of interest from karate students in learning kobudo as part of karate training. Many times I have taught one or two classes in a country, left the area and those interested in pursuing the weapons part of karate, are left on their own without a chance to continue learning.

Others may live too far away from a major centre that has a kobudo teacher. Some people who are interested in kobudo may be part of a karate organization that does not include weapons in the karate lessons.

These web site is for all of you.

If you follow the lessons described on this site and conscientiously learn and practice each step of the lessons, you will acquire the knowledge equivalent to a black belt in kobudo. I have practiced kobudo for more than 20 years, but had to learn it from various teachers and sources, whenever and wherever they were available.


Mute Raven Kobudo is not associated with any style of kobudo or karate. The lessons are mostly based on the teaching and writing of Motokatsu Inoue Sensei. The stances I use in this lessons are those of the Shito Ryu style, if you are student of another style of karate you can substitute the stances you use in your karate style.

In the old days in Okinawa there was no belt grading system and in Japan there was initially no grading system for kobudo either. Kobudo was taught mostly to advanced students (usually green belt and higher) only.

In the Mute Raven Kan Kobudo system we have used a different approach based on the belt colour system used in karate. Starting as a white belt you can progress gradually to more advanced levels and advanced katas. When you have completed all the lessons, you will have mastered the use of Bo, Sai, Tonfa and Nunchaku.

All the information is free. If you like this site and this system, please donate some money for the maintenance of this site.

I will not issue any certificates, I do not want to take on the responsibility to grade or keep track of their students’ individual progress. Under the lesson tab, there is a self-issued certificate, that you can complete, if you believe that you have mastered the content of a lesson. It is simply based on a honour system. You, yourself, sign the certificate when you believe that you have acquired the knowledge imparted in that specific segment.

The use of weapons, even the simple weapons of Okinawan kobudo, is inherently dangerous. Please take care when you practice kobudo. We are not responsible for any injury or mishap that may result in the use of the kobudo weapons.

In several countries there are restrictions on some of the weapons. For example in Canada it is forbidden to have to piece of wood or metal tied together with a chain or string (nunchaku). Brass knuckles of metal (tekko) are forbidden, so are chains that are weighted on one or both ends (surujin).
