American School of Karate & Judo

American School of Karate & Judo ASKJ is a Martial Arts School that primarily teaches 5 Circle System and Brazilian Jiu-Jitsu (BJJ). Participation in competitions is optional.

The American School of Karate & Judo (“ASKJ”) teaches a system of martial arts known as the 5 Circle System, which was founded by Grandmasters John Byrne and Edward Byrne. The 5 Circle System is an integration of techniques from numerous martial arts, including Taekwondo, Karate, Judo, and Jiu-Jitsu. ASKJ’s program is designed to help students grow physically, mentally, socially, and emotionally,

while teaching students to defend themselves against various threats of violence. ASKJ’s program is also tailored to develop a student's self-confidence, leadership skills, and principles of good moral character. Achievement at ASKJ is not measured in championships or trophies. Instead, achievement is measured in terms of accomplishing personal goals, conquering fear, and achieving personal excellence. ASKJ also teaches Brazilian Jiu-Jitsu (BJJ), which is a martial art that focuses on grappling and ground fighting techniques with the goal of gaining a dominant position over an opponent and forcing a submission using joint-locks and choke-holds. BJJ promotes the principle that a smaller, weaker person using leverage and proper technique can defend against a bigger, stronger assailant. The classes are designed for students who are interested in self-defense, fitness, and personal improvement.

ASKJ will be closed on Saturday, May 30th, as we will be walking in the Elkhorn Days Parade at 10:30am. Students/instructors are invited to walk with us in the parade. Students walking with us should meet us on the parade route around 10:15am and wear their uniforms or an ASKJ t-shirt.

All minors walking with us need to be picked up on 205th and Corby St. (near Uptown Java) when we walk by at the end of the route. We will email a map of the parade route and our position in the parade next week.

Black Belts are invited to meet at ASKJ at 9:30am to carpool to the parade.
We hope to see you there!
