Within the Bugei Jūhappan – the recognised 18 skills of the ninja – there exists a discipline often misunderstood, but perhaps more valuable today than ever: Intonjutsu, the art of escape and concealment. Out of these 18 skills, I have developed knowledge, training methods, and teaching applications in 11 disciplines, and Intonjutsu is one of the most directly relevant for modern self-defence and personal safety.
What is Intonjutsu?
At its essence, Intonjutsu is about disappearing from pursuit and avoiding capture. It was never about “magic” or vanishing into thin air, but about practical tactics: breaking line of sight, using natural and man-made cover, and knowing when to hide and when to move.
It includes methods of masking movement, reducing visibility, misleading pursuers, and creating opportunities to escape. But more than the physical, Intonjutsu also deals with the psychological — the ability to leave opponents uncertain of where you are, or even whether you were there at all.
Physical Application – Making the Body Invisible
In historical terms, Intonjutsu involved moving silently, wearing disguises, or using shadows and terrain to slip past danger. But the same principles apply today in more everyday forms.
For example:
Breaking Line of Sight: If you sense someone following you in town, quickly changing direction around a corner or through a doorway disrupts their pursuit.
Using Cover: Cars, walls, crowds, or even lighting can become concealment. Standing still in shadow is often more effective than running blindly.
Controlled Movement: Jerky, panicked movements draw the eye. Calm, natural walking blends you into the environment far better.
The body is always visible — but Intonjutsu trains us to manipulate how it is perceived.
Psychological Application – Disappearing From Awareness
Intonjutsu is not just about physical hiding. It’s about becoming unimportant in the mind of the aggressor. Attackers often choose targets who stand out: distracted, flashy, or predictable.
By adjusting body language, eye contact, and presence, you can appear less noticeable. Blend into a group. Delay your exit. Let an aggressor’s focus drift. Sometimes, the best form of concealment is to behave in a way that makes you seem unworthy of pursuit.
When used effectively, Intonjutsu creates doubt. Doubt makes pursuers hesitate. That hesitation gives you space. Space gives you survival.
Training Intonjutsu Today
This is not a forgotten relic — it is a life skill anyone can practice. Here are ways I train and teach it:
Shadow Drill – Move between pools of light and shadow, practicing pauses in the darkest areas. Learn to “disappear” even when visible.
Breakaway Drill – A partner follows you through a set route. Your task is to lose them using only changes in direction, crowds, and natural cover.
Freeze Drill – When cued, stop instantly in place and become still. This builds composure and shows how stillness can sometimes hide you better than motion.
Urban Camouflage Drill – Change appearance quickly using everyday items: a jacket, a hood, glasses, or posture. Learn how subtle shifts change recognition.
Psychological Vanish – Practice de-escalation body language: lower profile, non-threatening presence, avoid eye contact, reduce emotional energy. Disappear socially before you disappear physically.
Why Intonjutsu Still Matters
In my criminology research, I’ve seen time and again how predators select victims. They rely on visibility, predictability, and opportunity. Intonjutsu removes these advantages.
It doesn’t make you invincible. It makes you harder to find, harder to follow, and harder to control. In a world where personal safety is often about avoidance rather than confrontation, that difference can save your life.
Conclusion – The Power of Vanishing
Intonjutsu reminds us of a simple truth: you don’t have to win every fight — sometimes you just need to not be there. By mastering the art of disappearing from awareness, we learn to control whether we are seen, pursued, or even chosen as a target.
Out of the Bugei Jūhappan, this is one of my 11 personal disciplines because of its direct relevance to modern life. From urban safety to real-world survival, Intonjutsu is not fantasy — it’s awareness, strategy, and intelligent concealment.
Train it. Live it. Because sometimes the best defence is not being found at all.
