Below are some benefits of our training style

Strength and Power

While form is important for an effective karate punch or kick, strength is also needed to ensure that your attack is powerful. Conversely, practicing karate in San Diego will provide you with the opportunity to train your body to become stronger and more formidable. Such disciplines as Kosho-Ryu/Kajukenbo require a lot of strength, when it comes to some of its techniques. These kicks, punches, and other moves will increase your entire body’s strength over time. Repetition is another factor that can help improve your body’s musculature.


Executing such things as high kicks or dodging attacks requires a lot of flexibility. In addition to that, having a more pliable body can help reduce the likelihood of injury, making flexibility important for any athlete. Certain disciplines – such as karate and jiu-jitsu – can help you improve your flexibility since their moves require that of your body.

Cardiovascular Health

Meeting the physical activity guidelines of the Center for Disease Control and Prevention can be difficult. According to their research, only one in five adults actually meets their suggested amount of exercise. Cardiovascular health benefits, in particular, is very important to manage, as it is closely linked to heart health. Especially during training, drills can really help ramp up one’s heart rate, helping you build cardiovascular endurance and increasing the positive impact of your aerobic exercise.

A Words from Sigung

I’m Sigung Darryl James owner and chief instructor, and I with my wife Cheryl, a practicing Child Psychotherapist and faculty member at San Diego State University and the proud owners of the James Martial Arts Academy. As a Kosho-Ryu and Kajukenbo style instructor with extensive experience training kids, there is nothing better than seeing them grow firsthand.

More importantly than the uniforms and self-defense skills, they learn as the personal skills they develop and carry for life. Because our discipline is so much more than just kicking and punching, and getting the next colorful belt, it’s about developing confidence, discipline, character, focus, and respect. With every class we teach, your kids are growing in mind, body, and character.

That’s because the Japanese style provides instant positive feedback. By learning to focus on the core moves, they develop discipline and respect. They can instantly see and feel a difference, making them destined to build confidence, self-awareness, and self-respect.

And of course, it’s a ton of FUN! That’s why I love teaching kids in this community, and why I know your kids are going to LOVE training. As a bonus of training with us, our students have appeared in four films.

Please have a look below to find out exactly how your kids can benefit from the fun classes we also have training videos.
I’m looking forward to meeting you at our San Diego academy.

-Lanny Kimsey

Sifu Darryl is the ideal martial arts instructor. His demeanor is friendly, approachable, respectable and fun; while at the same time firm and accountable. Sifu’s ability to teach young kids to have fun while simultaneously challenging them to follow instructions and learn is simply outstanding. As an adult student, Sifu’s style incorporates many forms of martial arts which helps me incorporate my previous training. If you’re considering a martial arts studio in this area, then be sure to stop by and try his class for yourself. I’m confident you’ll enjoy your experience.

-Thomas Wilkins

With so many disciplines in Martial Arts schools, it can be confusing for many people to pick an instructor or school to train. In the current climate of Mixed martial arts, many people may gravitate towards Brazilian Jiu Jitsu or Grappling training for understandable reasons. Choosing an Instructor or school is often about personal preference. As someone who has witnessed the aftermath of crime and violence for 20+ years, I fell it is important to consider three things: 1) A highly competent/qualified Instructor/Coach; 2) A Reputable and sound training curriculum that addresses all ranges of combat and self defense to include: striking, grappling, weapons and multiple attackers; and 3) Physical conditioning during the class that conditions and strengthen the mind and body.

The answer is…it depends! There are 10 levels of black belt in Japanese martial arts – the first one is called shodan. The minimum required time to get to shodan in 5 years, but most people take 5 – 6 years. It takes consistency, practice, and a commitment to understanding the principles of your martial art. Beware of schools that promise you a black belt in a set period…they are selling you a belt but not necessarily training you to be good at martial arts. It does take time.

But on the way, you’ll become fitter and more confident, you’ll make good friends, and you’ll learn a host of skills that will help you succeed in life! See our Instructors Page for a few of our most prominent black belts.

It can mean many things, some obvious and some not so obvious. A few of the major aspects of a traditional dojo include a verifiable lineage in a recognized historical style, a respectful atmosphere, reasonable fees, and observance of basic formalities.

One reason many people seek out traditional martial arts is that they are more likely to teach dignity and mutual respect. Martial artists who want to become leaders recognize the importance of the quiet confidence that only traditional martial arts training can instill.

What is Kosho-Ryu?

Kosho – Ryu Kenpo now sometimes called Kosho-Shorei Ryu Kenpo is one of the most thorough martial arts systems. Some teach under the name of Kosho-Shorei Ryu Kenpo, which teaches the psychological aspects of the art; others teach Kosho-Ryu Kenpo, which are the physical aspects.

Kajukenbo is a hybrid martial art from Hawaii. The name Kajukenbo is a portmanteau of the various arts from which its style is derived: KA for Karate, JU for Judo and Jujitsu, KEN for Kenpo and BO for Boxing (Kajukenbo). It’s known as the first MMA.

Karate is a martial art that primarily involves punching, kicking, and blocking. The practice consists of kata (forms), Kihon (basic skills), randori (free practice), and Kumite (sparring). It is an excellent martial art for teaching balance, distancing, and timing, and is very useful for self-defense. At the Japanese Martial Arts Center, striking is taught in the jujutsu program. Although karate practitioners specialize in striking,

Jiu Jitsu practitioners use striking as an adjunct skill to their takedowns and joint locks. For more on Kosho-Ryu and Kajukenbo, see our adult Page. For more information on our Kids Karate program, see our Kids page.


Jujutsu (also written jujitsu or jiu-jitsu) is a Japanese martial art that typically focuses on defense against attacks such as strikes, wrist grabs, chokes, bear hugs, and kicks. After avoiding the attack, the jujutsu practitioner applies a joint lock, strike, takedown, or throw.

The practice is systematic, starting with simple, safe techniques, and gradually getting more technical and advanced. However you spell it, jujitsu is useful for self-defense, great for cardio, and a terrific vehicle for personal development. At the James Martial Art Academy in San Diego, CA, we teach Kosho-Ryu Kenpo Jujutsu, Kajukenbo, and Kung-Fu. Kosho-Ryu was brought to the United States by James Masayoshi Mitose in 1936.

Kajukenbo was It was developed in the late 1940s and founded in 1947 in the Palama Settlement of Oahu, Hawaii by Adriano Directo Emperado who studied Kosho-Ryu and received his black belt from James Mitose.
