About 9Jitsu
9Jitsu (pronounced “cue-jitsu”) began when Yuki Nakai black belt Mark Arbo, looked to create a place for his own daughters to train in his beloved Brazilian Jiu-Jitsu. With emphases on fun, fitness and family, 9Jitsu quickly expanded into a thriving community, offering a variety of classes for all ages & skill levels. Whether you're here for yourself or your kids, for self-defense, competition, fitness, or simply to hang out with an incredible group of people, 9Jitsu is where you belong!
OUR PROGRAMS
Brazilian Jiu Jitsu, MMA & Kickboxing
Sasebo & Arita
Spider Monkeys & Me
Of all our programs, this might be the one we are most proud of. There isn't really “fighting” in this class. It is play: fast-paced games & movements that a parent & child learn together & can practice anywhere. To the child this often seems like nothing more than a fun time with mommy or daddy, but they are actually learning fundamentals, movements, sequences & reactions that will serve them the rest of their lives!

Brazilian Jiu-Jitsu is one of the most powerful tools a child can have—not just for self-defense, but for having an amazing life. Confidence comes from facing fears & challenges head-on, & a confident kid is nearly unstoppable!
Our Ninja Classes are high-energy, engaging workouts where kids learn the fundamentals of Jiu-Jitsu in a safe, encouraging environment. They’ll develop discipline, focus & respect—cornerstones of martial arts—while building real-world skills like perseverance, humility & leadership.
More than just a sport, Jiu-Jitsu teaches kids how to stay calm under pressure, think critically, & overcome obstacles— & it's also super fun!
