Definition
Shōnen
/ show-nuhn / · noun
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.
In a shōnen story, the hero doesn't start out strong. They train, they get knocked down and they get back up a little better every time. That's jiu jitsu. Every class asks for a little self-perfection and a little self-discipline, and gives back a team that shows up for each other, on the mat and off it.
Our story
From Costa Mesa to Glen Burnie.
Professor Lee Rosenfield earned his black belt under the legendary Mendes Brothers and taught kids and adults at their Art of Jiu Jitsu Academy in Costa Mesa, California, one of the most respected academies in the sport. As a coach there, he was part of five IBJJF Kids Pan American team titles.
He brought that same curriculum, and the same standard, to Maryland. Shonen was built to offer world-class instruction that specializes in jiu jitsu, instead of following the trend of being a sub-par MMA school. Every class is organized, supervised and taught with the same attention to detail, whether it's your first day or your hundredth.
