Relson Gracie is the second oldest son of Grandmaster Helio Gracie, the man who is credited as innovating the Jiu-Jitsu taught by Mitsuyo “Count Koma” Maeda to his brother Carlos Gracie into what is now known as Gracie Jiu-Jitsu, also referred to as Brazilian Jiu-Jitsu. The Gracie’s have demonstrated their martial arts mastery in Vale Tudo, Portuguese for “Anything Goes” competitions, which is the precursor to modern day Mixed Martial Arts. By constantly testing and refining their art after testing it against martial arts masters to street fighters in the mean streets of Brazil. Relson was more than happy to not only defend the family name, but also prove the effectiveness of Gracie Jiu-Jitsu. Relson’s ferocious fighting style quickly garnered him the reputation that, of all the Gracie’s, he was the last one you wanted to test yourself against. Although Relson’s techniques are deeply rooted in Gracie Jiu-Jitsu, as taught to him by his father, Grandmaster Helio Gracie, his personal style has focused on “street effective” techniques. As such, he has developed a Jiu-Jitsu designed for defending yourself in a survival situation where there are no rules. Gracie Jiu-Jitsu is broken down into Sport Jiu-Jitsu for competition, self defense techniques, and vale tudo techniques. We provide instruction in each of these facets of Gracie Jiu-Jitsu.

We are the first Relson Gracie Jiu-Jitsu affiliated school in the world and one of the powerhouses of the Relson Gracie Team. The Jiu-Jitsu and Submission Wrestling classes are led by head instructors Chris and Mike Onzuka, Kaleo Hosaka, Robert Moss, Kyle Snyder-Olivares, Grant Arakawa, Chris Slavens and Craig Uchimura. Mike is also a Judo brown belt from the  Shobukan Judo Club, Kaleo is a Judo brown belt from Leeward Judo Club, and Kyle is a Judo brown belt from Mililani Hongwanji Judo Club and all of the instructors implement Judo and Wrestling into the Jiu-Jitsu program to implement take downs. We feel that in order to implement Relson Gracie Jiu-Jitsu our students must also be very comfortable with take downs and throws as well as ground techniques.

Our philosophy for our kids classes is simple; if kids have a lot of fun in class, they will WANT to train.  Any child who loves going to the class, tries their best, and attends consistently will get good at the martial arts.  There are so many things in a child’s life to be serious about, like their school work, chores, etc..  Every child needs an activity that is fun.  It is even better when that activity is one that gives the child exercise, increases flexibility and builds strength, teaches them how to defend themselves and the respect and discipline to know when to use it and, more importantly, when not to.

We do not want over demanding parents to bring their children to our academy and demand that we make them into the next champion of the world.  If your child will become a world champion, he or she will make that decision themselves because the desire needs to come from within themselves.  To reach that level, they cannot be forced to obtain those types of skills.  Every child that we have built into a champion developed a passion for the martial arts on their own.  We enjoy watching the children’s self confidence and self esteem grow as their technical proficiency grows. Not every child will become a champion, but every child deserves to feel a boost in their self esteem & self confidence, and feel better about themselves through the learning of the martial arts.  We are not only building champions in martial arts, we are building champions in life.

“Instruction does much, but encouragement does everything.”
Johann Wolfgang von Goethe, 1749-1832, German Poet/Dramatist/Novelist

We reserve the right to not accept certain students both adults and children. Acceptance of children for the kids class will be based on the child’s level of maturity. If the child can sit still for a little while listening to instruction, pay attention, and TRY to attempt some moves when shown something, they will be accepted.  We are not asking for young adults, but this is also not a baby sitting class. We also do not feel right about taking money from parents if the children is not ready to learn.  Every child is different and progress at different rates.  That is the great thing about kids.  Our classes target 6 – 14 year olds. We are always open to ideas, suggestions and willing to try just about anything, so do not be afraid to ask or offer.  Kids 15 years and older are encouraged to attend our adult classes.

Our goals in the Kids class are to have fun, build self-confidence and self-worth, emphasize academics, build discipline, develop humility and respect for others, instill good ethics and morals, be an “extended family” support team for the child, and increase flexibility and overall fitness through the learning of Jiu-Jitsu.
