Welcome to Pacific Rim Martial Arts Academy in Tigard. This is the Honbu (Headquarters) of the Zen Ei Kan International Association. Students who train at Pacific Rim have the guidance of Michael Martyn Sensei (President of Zen Ei Kan International), as well as the added benefit of several high ranking instructors.  Students at Pacific Rim have the opportunity to train in six unique, yet complimentary martial arts; Tomiki Aikido, Kodokan Judo, Japanese Jujutsu, JuSoolKwan Hapkido, ChungDoKwan TaeKwonDo, and Ryushin Shouchi Ryu Iaido.  Visiting students (ZEKI members and non-members) wanting to train at Pacific Rim are required to schedule an appointment with Martyn Sensei ( prior to visiting.

We must not forget Jigoro Kano’s thinking about the true purpose of Judo and its aim to benefit society through the development of people. Michael Martyn has a Japanese soul and Pacific Rim is the dojo that embodies Kano’s mindset and actually drives into it real life.

Jigoro Kano taught us that through Judo each person can develop a strong character and create new friends from all over the world. At Pacific Rim, students are committed to becoming true judoka, and I could truly feel their dedication to training and mutual prosperity.

At Pacific Rim you have a chance to learn martial arts from a very diligent and sincere instructor. In all my travels, I have never seen such a great and beautiful dojo and my dream is to one day own such a wonderful dojo. I highly recommend Pacific Rim!
