I'm a very shy person and wanted to come out of my comfort zone so that's why I've decided to join this club. The staffing and coaches are extremely friendly and welcomed me right away! The coaches and staff are very patient and are willing to teach above and beyond! The dojo is very clean and organized. There are classes everyday which is great if you have a busy schedule. I'm very happy and excited to continue coming to practice! If you're looking to start BJJ somewhere and don't know where to go, I highly recommend CJJF!!

If you want to genuinely feel that Gracie Barra one team one family vibe this is the Gracie Barra you need to go to. Professor Justin went above and beyond to make my kids feel welcomed and a part of the family. We tried another Gracie Barra on Oahu on their opening day and we did not feel welcome. Aloha Stadium upholds all of the Gracie Barra philosophies, curriculum, and uniform policies. It's extremely professional and really upholds the Gracie Barra way. My children do Jujitsu to help them become better people, learn how to defend themselves, and learn how to get back to their community and they learn all these things here at Aloha Stadium.

I contacted the school in advance and was able to visit and train with them. My 10 yr old son was able to go and train once with the juniors while we were on the island.

I glad I went as Prof. Justin James pointed out a couple of things I needed to improve and then went about teaching me how to do that. All in all, I highly recommend this school to either join as a regular student, or visit and train with them when in town.

The instruction, atmosphere, and hospitality were all top notch. If you're visiting Honolulu and want to get some training in, this is absolutely the place to go. Highly recommend!

With that said we are both brown belts and have been training for over 8 years and have been to many different academies. We had been looking for a new school to train as we had "outgrown" our previous school. What made Kansept stand out was the head instructor (Professor) Jeremiah (Miah) San Nicolas. Miah is a high level competitor who has an extensive knowledge of Jiu jitsu. He is very detailed in his instruction and has a very structured approach. I can honestly say my Jiu jitsu game has improved significantly in the short time that I have trained here. Come by and try a class, you won't be disappointed. OSS

I definitely would recommend Kansept Academy for anyone looking to train jiu-jitsu in Oahu.

The people who train there are really friendly and quick to offer helpful tips. Their Jiu Jitsu is top notch and very technical. Not the typical smash and pass style that you see at some other gyms. We watched a kids class and Coach Edmund is very patient and makes the class enjoyable. You can tell that the kids are having fun yet still learning a valuable skill. My son also did a private lesson with Coach Edmund to help prepare him for an upcoming tournament. Edmund took the time to watch a video of my son competing and worked with him on things that needed improvement. Sadly, we live on the other side of the island. If we didn't, I would love to have my son train there. If you're looking for a Jiu Jitsu school with no drama or big egos but yet very technical, then Sapateiro is the place to be.

I joined about two years ago for kickboxing (PJ, Chris, and Justin are incredible), but really appreciated that the membership allows you to divide up your classes however you like. I ended up taking up jiu jitsu and recently started kali escrima with Ian - my only regret is that I didn't start sooner. Marital arts is such a humbling experience, and walking into a new gym can be so intimidating. O2 is perfect for every experience level from the individual who has only seen action movies to the high level grappler and those who spar regularly. As a whole, they call it the O2 fam and it truly feels like it! The gym is actually owned by Mike and Chris, two brothers, who truly give it a family feel. They, and all the coaches, are amazing at what they do and lead their classes with expertise and a lot of humor. And as another reviewer mentioned, this is definitely somewhere where you have to check your ego at the door because it's a fam and we have to take care of each other. O2 is on the second floor above Goodwill along Kamehameha. There's plenty of parking and the lot entrance is on Hekaha. During the pandemic they kept the gym open and prioritized membership safety with online classes then grappling with dummies and working in pods. They offer times throughout the day and on weekends. The schedule is a little modified because of COVID but definitely check them out!
