through KARATE

Shinken Kan teaches a deliberate path to reveal the good in us as human beings through the truthful art of Ryukyu Kempo Karate.



Welcome to Shinken Kan! My name is Justin Leavitt and I am passionate about learning, teaching, and passing on the art of karate. I teach karate across the US, internationally, and at my current dojo in Belton, Missouri.

This site is to educate, inform, and inspire students of karate as well as those seeking to be a part of the adventure of karate for the first time.


​What is Shinken Kan​?

Shinken Kan is a school in the United Ryukyu Kempo Alliance with a passion for life protection and passing on the truthful art of Ryukyu Kempo Karate. We work towards achieving clarity in our karate and in our lives as a whole as well as being deliberate in all of our actions and behavior to seek the truth. A deliberate heart makes a deliberate hand.

We offer life protection classes in Belton, Missouri. Our classes will help you build a solid framework around protecting yourself while developing self-confidence and a strong body, mind, and spirit.
