O2 Martial Arts Academy

If you live on the leeward side of Oahu, this is the martial arts academy for you! Although there are a handful of practitioners from town, most of everyone you meet here live this side of the island. Great centralized location, parking is free, instructors are top notch, rates are great for what they offer and you are guaranteed to make good friends with a group of great men and women.
If you want to become a jiujitsu practitioner and want to learn self-​defense, O2 has all you need from highly decorated black belts and owners, Mike and Chris Onzuka and black belt, Kaleo Hosaka. All trained and certified from hawaii’s first own Gracie, Master Relson Gracie.
O2 offers day and night brazilian jiujitsu classes for adults and children, kickboxing and wrestling in the afternoons, and Kali-​escrima. Classes are about two hours for jiujitsu and hour and a half for kickboxing. This academy offers basically all you need from ground to stand-​up.
Facility is located on the second floor right over goodwill aiea, fronting Kamehameha Highway next to Best Buy. Training area is clean and organized, restrooms are available, and if its your first day, its totally free! First day I joined, I was hooked!

Very easy to find. Located directly across the Waimalu Shopping Center, right above Goodwill. Parking is limited, especially between the hours of 4 – 6 p.m. weekdays. The tenants are sticklers about parking, so make sure you park in a place that’s not directly in front of another business. Safest place to park is at the ends of the parking lot.
O2 Martial Arts Academy offer a variety of classes for all ages including Gracie Jiujitsu, boxing, kickboxing, Kali/​Escrima, and wrestling.
The facility was recently renovated with a bigger space and new mats and equipment. The facility is always clean and lacks that sweaty, workout smell, WHICH IS GOOD!
