Our Vision

With a deep respect for traditional martial arts, Pacific Rim Martial Arts Academy strives to create meaningful relationships with our students, while passing on the art of self-defense and self-reliance.  Our philosophy of respect, discipline, courage and consistency is the template for developing great people.

As expressed by the characters ZEN EI KAN (善榮館), everything we do is dedicated to fostering an environment where each student is challenged to reach their fullest potential, while contributing to the development of others through the principle of mutual welfare and benefit.


Designed and Tested for Success

At Pacific Rim, We teach six distinct yet complementary modern martial arts; Kodokan Judo, Nihon Jujutsu, Tomiki Aikido, JuSoolKwan Hapkido, ChungDoKwan TaeKwonDo and Ryushin Shouchi Ryu Iaido.

While many of our students specialize in one art, most enjoy training in more than one art to enrich their experience.

With 40 years experience on the mat and black belts in six different arts, learn more about his approach to developing great martial artists and people.

Jigoro Kano taught us that through Judo each person can develop a strong character. At Pacific Rim, students are committed to becoming true judoka, and I could truly feel their dedication to training and making deep friendships through mutual prosperity.

2x World Champion

Pacific Rim is a great dojo with many tatami, world-class equipment and a beautiful building.  Students practice hard with respect and seriousness and I could see their love for learning Judo. I can’t wait to return and teach at Pacific Rim again.

World Champion

Mike Martyn has a Japanese soul. I have met many instructors from around the world, but he is different. He understands Kano’s vision for judo and is a true judoka. I am happy to know him.
