 Formally the Academia Casca Grossa de Jiu-Jitsu (Casca Grossa Jiu-Jitsu Academy) The Relson Gracie Jiu-Jitsu Aiea Association Welcome to the O2 Martial Arts Academy's site! Come train at the only place in Hawaii that has 4 Relson Gracie Black Belt Instructors at One Academy! Click here to go to the Onzuka.com Daily updated News Page!  O2 Martial Arts Academy (formally known as Academia Casca Grossa de Jiu-Jitsu or the Relson Gracie Jiu-Jitsu Aiea Academy) is based out of Aiea, Hawaii. We are still a Relson Gracie Jiu-Jitsu Association school and part of the Relson Gracie Team. The Jiu-Jitsu and Submission Wrestling classes are led by head instructors Chris and Mike Onzuka, Sam Mahi, and Shane Agena. Chris, Mike, and Sam were three of only four instructors that were hand picked by Relson Gracie and specifically trained to open Relson's first satellite academy in 1995. Chris, Mike, Sam, and Shane are all Relson Gracie Jiu-Jitsu black belts and are numerous state Jiu-Jitsu championships and multiple time competitors in the World Championships of Brazilian Jiu-Jitsu (Mundials) and Pan American Jiu-Jitsu Championships. Mike and Shane are also successful competitors in Judo and both have brown belts from the prestigious Shobukan Judo Club. We have also added Kali-Escrima to our list of classes instructed by Ian Beltran, a long time student of the late legendary "Snookie" Sanchez. Our school's philosophy is simple. This academy is for the students. We start out with our vision of the ideal class. Basically, if we were students how would we want the class run? And then from there, we make improvements by taking students' suggestions and comments about the class and implementing those ideas. We feel that no one is too inexperienced to offer a suggestion, ask a question or make a comment. In fact, we welcome them. Every person that trains at O2 Martial Arts Academy is considered and treated like family. That is why end up spending so much time in and out of class together. "The mediocre teacher tells. The good teacher explains. The superior teacher demonstrates. The great teacher inspires." William A. Ward We are constantly seeking out methods to be better instructors. We consider ourselves students who teach because we are constantly learning. This philosophy transends to our higher ranking students who naturally follow the same path, which helps accelerate the progression of the newer students. We have a great student to teacher ratio to ensure that a high level of personal instruction occurs and so that the students get the most attention for their hard earned money. We invite anyone with an open mind, good heart and who is able to check their "ego" at the door to come join our Martial Arts Family.

Note: GJJ = Gracie Jiu-Jitsu Last classes of the night usually end much later if students want to continue to work out, but it is subject to the instructor's direction. All classes are Mixed Levels (Beginner, Intermediate, and Advanced), but classes are split up in to beginner and intermediate/advanced sub-classes within that one class. All levels warm up together and spar together at the end of class to build the team atmosphere and for more bodies to train with. Presently, we alternate gi (uniform) and no gi (t-shirt and shorts) days on Tuesdays and Thursdays. For example, if Tuesday is gi, then Thursday is no gi. The next week we alternate the class that has a gi and the class that has no gi. Currently Fridays are back to no gi! All other days for Jiu-Jitsu are with the gi. The Kids classes will be gi only with occasional no-gi classes slipped in periodically. We teach students with no grappling or striking experience to high level competitors. Everyone is welcome! Kid's Class Notes: 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, 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. 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. We reserve the right to not accept certain students both adults and children.
