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.
Enthusiastic to Learn Self Defense
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.

Adult Martial Arts Classes – For All Levels
Our Martial Arts classes for adult beginners are perfect for anyone wanting to build strength, agility, and smart defense skills—without needing any prior experience. Techniques are easy to learn, and you'll improve focus, discipline, and self-trust.
What You Will Learn
- Practical Self-Defense: Bujinkan Budo Taijutsu is a martial discipline crafted for genuine combat situations rather than sporting events. Its methods depend not on strength or physical ability but on timing, distance, and energy redirection, making them very efficient in the unpredictable turmoil of battle.
- Warrior's Mentality: In actual self-defense scenarios, there are no regulations—only the imperative to stay alive. The ego-centric quest for victory in martial arts can obscure decision-making and hinder the flexibility required for authentic self-defense.
- Combat, Not Sport: This discipline emphasizes self-defense techniques for safeguarding yourself and others in the face of an attacker, no matter the circumstances. These arts lack any sports application—there is no competition for titles or points. Instead, the emphasis is placed on utilizing any methods required to guarantee your safety.
- Personal Development: It provides personal growth in areas such as self-control, self-assurance, emotional awareness, and understanding of situations.
