Shonen is superior to your average martial arts academy


Shonen [Show-nuhn] – High-action narratives that focus on competitions or fights to decide their storylines. These stories stress values such as self-perfection, self-discipline, and honorable service to community, family, and friends. 

At Shonen you become the hero of your own story.


We created an atmosphere where everyone feels welcome. Be it a beginner with no previous training, or a seasoned competitor, we offer a genuine martial arts experience. We value your budget. Thus, fair & transparent business practices are important at Shonen.


The vision for Shonen was to offer world class instruction that specializes in Jiu Jitsu instead of following the trend of being a sub-par MMA school. Professor Lee is the most qualified instructor, with proven success as a competitor and coach at the highest level of the sport.


We care about your health and safety. Our state-of-the-art facility's bathrooms, lockers, and mats are cleaned and sterilized daily. Our training mats feature a raised floor for your safety. We guarantee the most organized and well supervised martial arts experience.
