What is Aikido?

        Generally known as a non-violent art of self-defense, Aikido was originated by Master Morihei Ueshiba after many years of training in both weapon and free hand arts. It is one of the most modern of all Japanese Budo (way of life through the principles of martial arts). The name Aikido was adopted in 1942 to shift the emphasis from martial art to a way of life, by removing the word Bu which means martial. The word Aikido comes from "Ai", meaning harmony, one.ness, agreement; "Ki", meaning nature, spirit, or universal energy; and "Do", meaning road, path, or way of life. Aikido then is a WAY OF LIFE THROUGH HARMONY WITH NATURE. Its outstanding features are its refinement from a physical martial art to an ethical but highly efficient art of self-defense and way of life that people, young and old, can practice and enjoy.

 Benefits of Aikido training include:

 · Promotes Health

Develops stamina and endurance as well as balance – both mental and physical.

 · Unifies Body, Mind and Spirit

Heightens mental concentration as the body and mind are trained to work together in a focused and efficient way.

 · Develops Character

Promotes honesty, kindness, self-respect and respect for others. Improves interpersonal relations. Nurtures the growth of self-discipline.

 · Teaches Self-Defense

Trains the student to use effective self-defense techniques that neutralize an attack without causing serious injury to the attacker.

 · Provides Alternatives in Conflict Resolution

Aikido, used as a metaphor, illustrates numerous alternatives to the use of force in resolving conflict.




Seidokan Aikido

                 Seidokan is a system of Aikido which emphasizes the balanced study of the principles and arts in accordance with the founder's teachings. One of the pri.mary objectives of Seidokan is to study the founder's sayings in Japanese, analyze them thoroughly, and relate them to the practice of Aikido techniques. Also at Seidokan, we are dedicated to developing methods to apply the founder's teachings in our modern way of life.

                 At Seidokan Aikido Dojo, students and instructors grow together. The students learn the basics from the instructors and the instructors gain deeper understanding of Aikido while sharing their knowledge with the students. Through earnest, realistic, and sincere training, we can realize the true meaning of Aikido.

Although Seidokan is independent from Japan, it was recognized by Master Kisshomaru Ueshiba, the late Doshu and Chairman of the Aikikai in Tokyo, Japan (Aikido Hombu Dojo). 

Seidokan founder and former director  Rod T. Kobayashi Shihan taught at California State University at Fullerton and at California State University at Long Beach and was a member of the Honor Society for International Scholars.

Kobayashi Sensei passed away in 1995.  The Seidokan Organization continues with the assistance of the Kobayashi family and dedicated students of Seidokan Aikido.

After practicing at a number of dojo in Los Angeles Dr. Mark finally settled at the Aikido Institute of America. Here he began an almost 20 year relationship with Seidokan Aikido Founder: Rod Kobayashi Shihan who quickly became the other major Aikido influence in Mark’s life.

In addition to studying across the States Mark has studied in both Hombu style and Ki Society (Shin Shin Toitsu Aikido) dojo in Tokyo, Kyoto and Chiba Japan.
