Jim is very knowledgeable and seems to know a variety of different martial arts. He was recommended to me by a martial artist I highly respect. Though it wasn’t quite right for me, he has a lot to offer the right students. His instruction is very reasonably priced.

After 10 years of not stepping in to a dojo, I went and visited to get back into judo. I was welcomed with open arms and had a great session. Very much appreciated. I am sore. I am humbled. But I feel whole. I was not made to feel belittled whatsoever at my loss of knowledge over the years. This is a wonderful place full of years of experience and knowledge. Sensei Rivera is a wonderful and patient instructor.

Owaza Ryu is the place to be if you want to learn from the best. The Shihan has decades of knowledge and experience to guide his students in the art of self defense. As a woman, I feel that it is extremely important to learn at least the basics of protection. Don’t be a victim! Go to Owaza Ryu to learn how to protect yourself TODAY!

My family has been involved with Owaza Ryu for over 3 yrs now. Soke Shihan Rivera is like no other and teaches no none-sense what works self defense. Shihan Rivera has over 50 yrs experience and his roots come from known long standing masters rooted in Japan and his martial arts family is very close. I highly recommend Owaza Ryu for those seeking to really develop and grow in their self defense skills while learning much about focus, health, discipline, and what the true essence of Bushido is all about for themselves.

One of the best dojo’s around. They care a lot about your learning experience. I really enjoy coming here. If you are looking into learning jiu jitzu and self defense, I highly recommend you try out this dojo!!

After joining the Dojo, my self confidence and ability to defend myself greatly increased. I really enjoy learning from Sensei and his staff! I drive from the next city over to go here. Dojo unlike the others around!

I just got into judo and couldn’t of chose a better dojo! Sensei Jim is very professional and detailed with his training. They are very knowledgeable and in the last 3 months I’ve learned a lot!

Love it! Its real and relevant! Just what our kids need!

Since my son started going to Owaza, he has more confidence in himself. He has learned a lot from Sensai Jim and Sensai Adam. The dojo is super clean.If students want to learn, this is the place to go. If people want an easy black belt, this is not the place.My first time meeting Jim and Adam I knew my son will love it. And he cant wait to go there everyday

With more than 50 years experience and training, Sensei Jim teaches what is useful not just the book lessons. He teaches from real life scenarios that will protect you and your loved ones. Joining Owaza Ryu Ju Jitsu has helped me to gain control and confidence at a time in my life when I didnt know what to do. Hes there for his students for more than just teaching Martial Arts, hes there to help in life as well. I am truly blessed to be a part of his dojo.

Owaza is a fantastic place to study and train in self defense and martial arts. It consists of like minded people who come to become physically and mentally fit. A place to learn new skills and hone and perfect existing ones. A place to learn confidence. It’s a place to come to so when push comes to shove you can defend yourself. I joined for myself, and now my wife and kids come to learn. Sensei Jim Rivera is a master to learn from. I can’t say enough about this incredible man. In closing I’m glad to of found him and thankful for Owaza.

My kids look forward to going every week and can’t wait to come home and practice what they have learned!

A very well structured curriculum and clean establishment that provides an excellent learning environment for both adults and children.

Awesome place to train! Been coming here to teach and learn for years. Not only does this place have great classes and energy, they host amazing seminars with top level martial artists throughout the year. Shihan Jim Rivera and his team are awesome! Highly recommended!

Great Martial Arts School!!

Had the opportunity to train there on numerous occasions. Both my students and I were welcomed with open arms by the staff every time. The staff is extremely professional, well trained in the martial art arts and is passionate about teaching. If you live in spring hill or close by, I would strongly recommend training here.

If you want the real thing Owaza is it.Myself and my grandchildren are students and this training builds confidence and teaches respect.There is no safe place anymore.I highly recommend this school.Sensei Jim Rivera offers over 50 years experience in martial arts.

This is the Best Self Defense school any student could ask for. Shihan Jim Rivera is a no nonsense old school martial arts teacher. You will leave every class tired covered in sweat, with a sense of self accomplishment. His techniques are some of the best I have ever seen, simple and effective. It is a great mix of judo, karate, aikido and ju jutsu. If you want to be a great martial artist i recommend studying here.

Excellent Master taught my 3 sons i highly recommend this school he has been teaching since 1973

II you are looking for a dojo that uses the traditional approach that focuses on character development as well as self-defense, then I would highly recommend Jim Rivera’s OWAZA RYU JUJITSU/JUDO Martial Arts. Sensei has many years of real life experiences as well as legitimate training and certifications in his craft. My grandsons have been working with Sensei for over 3+ years. They have thrived and remained motivated to learn due to his passionate, caring and patient attitude. These qualities are of great benefit- especially if you have kids with learning and/or attention challenges. Sensei values his kids and adult students’ learning and will often invite other master artists to come to his dojo to share their knowledge. This to me is the essence of a true teacher. It’s not about the money.

A great place for anyone of any age and gender.

Over 50 years experience traditional Combat ju jitsu Judo Karate aikido
