WARROR CREED

Wherever I go, everyone is a little bit safer because I am there.
Wherever I am, anyone in need has a friend.
Whenever I return home, everyone is happy because I am there.
It's a better life.

Welcome to Instinct Defense Academy, where we offer practical, reality-based self-defense and functional fitness training classes through our four different courses that are suited for everyone. Our aim is to show you not only how to fight but also how to live.

We have been teaching martial arts in the larger Portland region since 1991. Recently, we changed our name from "Bujinkan Family Dojo" to "Instinct Defense Academy" to better reflect our expanding services.

Martial Arts and Self Defense Classes in Portland

To gain from this training, you don’t need any prior martial arts experience or to be a super athlete; all you need is a willingness to learn. Since these are combat skills, strength and power often play a secondary role in distance, timing, and energy redirection. Height, weight, and physical strength are not relevant to being a good practitioner.

What We Are Offering

We practice the art of Bujinkan Budo Taijutsu, often known as Ninjutsu training. We will have different classes to train you. The methods provide more than just instruction in practical self-defense; they also promote efficient daily living. We have four different courses available for you;​

Trained here for a couple years, sadly had to stop because I moved away. Peter is one of the best instructors I've had in my life, in any discipline. The group is welcoming and accommodating of all experience levels, just an all-around great group of people to train with. Highly recommend checking it out.

Very welcoming environment to all who want to train and learn Self Defense. Beyond self defense, a way of life is offered. A family friendly atmosphere is promoted, and Peter Sensei is an excellent instructor with Decades of Martial Arts knowledge and understanding to impart.
Matthew Godsey
My children and I participated in a couple of classes to see if this might be a good fit for us. The instructors made us feel welcome. We really appreciated the serenity and the positive approach along with the profound instruction we received on the first day. This is a great place to learn both martial arts skills and very valuable skills for everyday life.
