We offer several other training options besides our judo classes.
Self-defense seminars are a powerful way to gain the confidence and practical skills to help you stay safe in any situation.
is also available in judo, classical Japanese ju-jitsu, kempo karate, and self-defense.
We can work with your group to provide self-defense instruction through private, individualized seminars.
Our self-defense program can be tailored to a wide variety of ages and situations to meet your specific goals.
We utilize a system of strategic thinking and self-defense based on three principles: Clear, Control, and Conclude.
Participants are given multiple options for confronting conflict situations, based on the level of risk the defender is placed in.
The goal is to neutralize a threat with only as much force as necessary.
Some of our clients have included: HMP Communications, Pure Mixed Martial Arts, the North American Center for Continuing Medical Education (NACCME), North Jersey Judo, Dominion Wrestling, LTS Lohmann Therapy Systems, and The Trauma Institute of New Jersey, along with a variety of Scout and student groups.
Here's what a few of them have to say about the program:
"Self-defense with Kevin and Sam was something I looked forward to every single week.
Every time I left the hour-long class, I felt strong, powerful, and more knowledgeable about defending myself.
The instructors were super friendly and very passionate about sharing their experience and skills with us.
They were open to any scenarios we wanted to discuss, or moves we wanted to try.
Although self-defense is a serious topic, the instructors still made the class fun.
The attention they gave every single participant is so valuable, and I know that I really appreciated the one-on-one feedback.
After completing this course, I feel that I am better prepared to use self-defense if I need to.
I would definitely recommend this class to both corporate settings and anyone who is interested in being able to defend themselves!"
- Sydney Turner, NACCME
"It is very rare that you hear that you were in the same room with a Martial arts expert that holds four black belts from four very lethal martial arts.
I had the pleasure to work with Kevin Costello during his Self-Defense class.
By far the most stimulating and fun class I have participated in.
Not only is Kevin extremely knowledgeable when it comes to applying the flaws of human anatomy against you, but his teaching style gives you insight on dangerous everyday social situations (getting grabbed at a bar, walking to your car alone at night, etc.) and provides a plan when/if you happen to ever be in that situation.
This class has all the tools necessary to train and entertain people from all ages, gender, and experience.
Kevin is patient and delivers the right personal touch to make everyone feel a part of the class.
If you want to explore how to develop confidence and a good relationship with yourself I would suggest getting started here."

Seminars can be held at our gym, or we can bring the training to you!

to develop a plan that fits your group's needs!
In addition to group classes and seminars, we provide private instruction in:
- Japanese Ju-Jitsu
- Kempo Karate
While judo focuses on grappling (throws, holds, chokes, and joint locks), kempo karate deals primarily in strikes.
The two arts are a great complement to each other.
Judo Kai's traditionally-based ju-jitsu program incorporates both grappling and striking to make a well-rounded, highly-personal self-defense system.
Students have the option to rank (earn belts) in either ju-jitsu or kempo karate through this route.
Sensei Kevin has definitely elevated my ground game to the next level.
My own personal ground game was much weaker and flawed until I started working with him.
I was growing increasingly frustrated with the fact that I was losing matches on the ground much more frequently than standing up.
With his help, I saw myself capitalizing on split second opportunities to win matches that could potentially not have been in my favor.
Not only does Sensei Kevin bring his own comprehensive arsenal of techniques and abilities, but also caters every technique and method to each person and their specific goals.
Through Strategic Ground Applications (SGA), I was able to enhance my ground fundamentals and close the gaps in my strategy.
I went from being vulnerable and exposed on the mat to being educated and prepared for any situation that arises.
I highly attribute my success at higher levels to Sensei Kevin.
I believe his training gave me the tools to help me win key matches and jump from #7 to #3 ranking on the USA Judo National Roster in my weight category.
I would recommend this program to anyone looking to improve their game."
