The Dojo

Dojo Philosophy

We at Yosokan Dojo believe that the more people are engaged in ongoing training (a life pattern of training), the fewer victims there will be and therefore, a more peaceful world. The teaching at our dojo focuses on gaining a deeper understanding of yoso, the “small things” that enable our techniques to work. These principles allow our students to function more effectively and efficiently on the tatami (mat) as well as in all of life. Through extensive application, attention to yoso has become the hallmark of the Yosokan Family.


Yosokan Dojo has classes available in Jujutsu and Battojutsu (Iaido) for adults and young adults. This would include those teen- and preteen aged individuals with both the maturity and body size to fit into the adult classes.  The first thing that the new student learns at the dojo is how to take good care of yourself as well as how to take good care of the person you happen to be training with. Our goal is to always have a safe and rewarding experience on the tatami and at the same time, to gain the powerful martial skills that will enrich your entire life. 

In my years of training and teaching in the martial arts I have found that KoKoDo Jujutsu is an incredibly effective combat fighting art as well as great self-defense. As a result, I have spent a number of years teaching combat-oriented jujutsu to military officers that come through the Naval Postgraduate School (NPS) here in Monterey. Many of these officers have served in Special Operations branches of the military. I have received letters of gratitude from some of them and certainly it has been my great honor to offer this level of training to those doing such vital work.
