Chinkuchi and Muchimi
By Jason S.D. Perry
Okinawa Shorin ryu Karate Kobudo Kensankai

There are two complementary concepts of Okinawan Karate that are often confusing to Japanese and foreigners alike.  Understanding of these concepts is only attained through countless repetition, which results in the body “learning” the concepts through experience.  The following essay offers an explanation of and relationship between the concepts of Chinkuchi and Muchimi.  Mastery of these concepts is for the reader to seek through rigorous training and self-discovery.

A Perspective on Bunkai
Kyoshi Jason Perry
June 22, 2017

“Even after many years, kata practice is never finished, for there is always something new to be learned about executing a movement”
Shoshin Nagamine

We often talk about Bunkai.  Many traditionalists will boast about doing bunkai in the dojo and not merely going through the motions of kata.  And this is good.  Kata is nothing without bunkai.  But I would like to offer a slightly different perspective on bunkai that I hope will give the reader something to think about and hopefully experiment with in personal training.  Read More

Lessons Relearned: A Few Thoughts on Karate Principles
By Kyoshi Jason Perry:
July 4, 2012 Musa Qala District, Helmand Province, Afghanistan

For my karate friends, I thought I would share some thoughts I have had recently on karate principles.  I am not able to go to a dojo but I still train and think about karate.  It is a little long and somewhat random so forgive the lack of structure and coherence.  A few things that have been on my mind follow.  I hope you find this enjoyable and maybe even helpful.  I also hope you will recognize my intended sincerity and humility and will forgive anything that smacks arrogant or judgmental.

Yakusoku Kumite – a discussion:

(約束) means appointment or promise.  Kumite (組み手) means to pair hands or spar.  Yakusoku kumite, therefore, is a prearranged set of movements done by two people.  One is a defender and the other the attacker.  Yakusoku kumite offers karateka the opportunity to execute kata-like offensive and defensive movements in a controlled environment.

Okinawan Symbols and History of the Hidari-Gomon

When one thinks of Okinawa there are a few common symbols that may come to mind. I didn’t really give it a second thought when I first saw them and simply believed that they stood for Okinawa the way a state symbol represents a state in the USA. I guess I never really gave it a thought what the various things portrayed in the state symbol for Wisconsin were either. Anyway, these symbols do have meaning and I will attempt here to explain the meaning of some very common symbols you may see when in Okinawa or any of the other Ryukyu Islands. Read More

This tensional network of  fibrous  tissues includes dense sheets such as muscle envelopes, aponeuroses, as well as specific  local adaptations, such as ligaments or tendons. Read More


Tai Sabaki
By R. Christian Estes, M.D.
Hachidan, Shorin Ryu Kensankai Karate Kobudo

In Okinawan Karate the objective is to avoid a fight, but if it cannot be avoided then do not loose. You train to fight so you do not have to fight, sounds like a long run for a short slide, but to the Okinawans courtesy is an essential characteristic of a human being. You must remember, Okinawa has never had a standing army, only guards for the King and police for the public. Read More

At the heart of Karate is the performance of kata, pre-choreographed self-contained ritual sequences of fighting techniques.  Kata is all at once the primary means of training, a library of technique, a cultural heritage, a form of moving meditation, and a graceful expression of the art itself.  This study will focus specifically on the performance of kata within the Matsubayashi Shorin-Ryu system of Okinawan Karate.
