When most people hear ninjutsu, they think of fighting. They picture strikes, throws, weapons, stealth, and self-defense. And yes, all of that is part of the art. But if we stop there, we miss something important.
In Togakure Ryū, the Ninja Jūhakkei, the 18 ways of ninja training, show us a much bigger picture. Alongside taijutsu and weapons, these 18 areas include things like Chōhō (intelligence gathering), Shinobi Iri (infiltration), Intonjutsu (escape and concealment), Hensōjutsu (disguise), and the study of terrain and weather. That alone should tell us something: the ninja was never trained only to fight. The ninja had to observe, adapt, move skillfully through the environment, and survive under changing conditions.
That broader understanding is one of the things that makes Sensei Mark Roemke’s teaching so valuable. Through Ninjas in Nature, students get to explore parts of ninjutsu that many people today overlook like tracking, camouflage, fire starting, plant awareness, bird language, and quiet movement through the woods. At first glance, those things may not look like martial arts. But when you understand the Ninja Jūhakkei, you realize they are right at home. Survival is not just about fighting, it is about perception.
The Ninja Jūhakkei and the Bigger Picture of Ninjutsu
The deeper you go into budō, the more connected everything becomes. The Ninja Jūhakkei remind us that ninjutsu has always included more than combat technique. Chōhō is about gathering information. Shinobi Iri is about entering skillfully. Intonjutsu is about concealment and escape. Hensōjutsu is about adapting your appearance and behavior. The study of weather and terrain teaches the practitioner how to read the world instead of simply reacting to it.
This is one reason nature-based training is so valuable for Bujinkan practitioners. Tracking supports Chōhō. Camouflage supports Intonjutsu. Quiet movement supports Shinobi Iri. Adapting to the environment reflects Hensōjutsu in a deeper sense than just putting on a disguise. The old traditions were never as narrow as modern people sometimes imagine.
Tracking Skills and Ninjutsu Awareness
Some of our students have also trained in the Tom Brown tracking tradition, and it is worth giving proper credit here. Those schools have done a great deal to preserve tracking, awareness, and nature-based movement in the modern world.
Tracking teaches you to really slow down. It teaches you to notice the bent blade of grass, the disturbed patch of leaves, the faint scuff in the soil, the branch that looks just slightly out of place. It teaches you to stop charging forward and start asking better questions, like what changed here? Are you rushing? Are you tense? Are you stomping through leaves and twigs without awareness? Or are you actually reading the terrain under your feet and the life around you?
In the dojo, we work on timing, distance, posture, balance, and efficient movement. In the forest, those same lessons become immediate and honest. Tracking sharpens the eyes, but it also sharpens the mind. It develops patience, attention, calm, and sensitivity. In that way, it is deeply connected to Chōhō (the gathering of information) and to the broader spirit of ninja training.
Concealment and Infiltration Start With Movement
When people hear the words “concealment” or “infiltration,” they sometimes imagine movie scenes or fantasy ninja tricks. Real concealment is usually much simpler. It starts with movement.
The Ninja Jūhakkei include Shinobi Iri and Intonjutsu, and those are not abstract ideas. They point to a very practical truth: stealth is not just about hiding behind something. It is about how you enter, how you travel, how you pause, and how little disturbance you create.
Most people move through the woods the same way they move through a parking lot… fast, loud, and disconnected. But the forest notices. Birds notice. Animals notice. Leaves notice. If you are heavy, restless, and impatient, the environment knows it right away. A good student begins to understand that concealment is not only visual. It is also rhythmic.
If your mind is scattered, your feet become careless. If your breathing is rough, your movement becomes jerky. If your body is tense, the whole environment feels it. This is why budō training matters outside the dojo. A calm person is easier to conceal than an agitated one. That is one of the deeper lessons of Intonjutsu.
Camouflage Training for Ninjutsu Students
Camouflage is another area people often misunderstand. A lot of people imagine camouflage as a clothing pattern. But real camouflage is much more than what you wear. What usually gives a person away is movement, shine, hard outlines, poor use of shadow, contrast with the background, and unnecessary noise.
Good camouflage is really about not breaking the natural pattern of a place. That means using shadows well, avoiding skylines, and paying attention to what is behind you, not just what is in front of you. It means reducing unnecessary movement and learning to settle your body so you stop drawing attention to yourself.
Sensei Roemke’s video on camouflage and tracking gives a look at how awareness, movement, and concealment come together in nature-based training.
A few simple ways students can start practicing camouflage right away:
- Pause before moving and study the light, shadow, and background first.
- Move more slowly than you think you need to.
- Avoid ridgelines and open spaces where your silhouette becomes obvious.
- Use natural cover without becoming stiff or artificial.
- Remember that sound is part of camouflage too.
This is where Intonjutsu becomes practical. Concealment is not a costume, it is awareness in action.
The Fox Walk: A Practical Stealth Skill for the Woods
One of the most useful skills many people bring back from tracking school is the fox walk. It is simple, practical, and it fits well in this conversation.
In the tracking traditions associated with schools like Tom Brown’s, the fox walk is a quiet way of moving in which you keep your posture tall, your knees soft, and your stride short. You keep most of your weight on the back leg while the front foot explores the ground. Only after you feel that the spot is stable and quiet do you roll the foot down and transfer weight. It develops your balance, patience, sensitivity, quiet movement, and terrain awareness. It also connects very naturally to Shinobi Iri. The fox walk teaches you how to move without committing too early. It teaches you how to let the front foot explore while the back foot supports. It teaches restraint, and restraint is a warrior skill.
Here is a simple beginner version of the fox walk:
- Stand upright with the head level and the spine long.
- Soften the knees slightly so the body can absorb movement quietly.
- Take a short step with the front foot, but keep most of your weight on the back leg.
- Touch down lightly on the outside edge of the front foot first.
- From there, roll to the ball of the foot as you feel the ground.
- Only after you know the spot is quiet and stable, let the heel come down last.
- Then transfer weight slowly and repeat.
That sequence can be remembered very simply:
1. Outside Edge
2. Roll to Ball
3. Heel Down Last
A helpful training tip: do not stare at your feet the whole time. Let your feet read the ground while your eyes stay soft and aware of the wider environment. That is where the fox walk becomes becomes an awareness drill, and awareness is one of the greatest survival skills there is.
Nature Training Builds Better Budo
One of the best things about training in nature is that it changes how you pay attention. The forest is honest. If you are noisy, impatient, careless or distracted, it shows. If you settle down, breathe, and really start to observe, something changes. You begin to notice patterns. You begin to understand timing differently and realize how much information is always present.
This is also where Sensei Roemke’s work with 8 Shields fits in. Their philosophy emphasizes deeper awareness, stronger connection, and a more complete relationship with the natural world. That harmonizes naturally with mature budō. A person who is more observant, more connected, and less reactive is harder to surprise and harder to shake.
Why the Forest Still Matters in Bujinkan Training
Ninjutsu is not just about how to fight. It is about how to move through life with awareness. The Ninja Jūhakkei in Togakure Ryū remind us of that. Chōhō teaches us to gather information. Shinobi Iri teaches us to enter skillfully. Intonjutsu teaches concealment. Hensōjutsu teaches adaptation. The study of weather and terrain teaches us to work with the world instead of against it.
So yes, train the strikes. Train the throws. Train the weapons. Also learn to slow down, read the land, move quietly, notice birds, and feel the weather. Learn to become less obvious. Sometimes the lesson of budō is not how to overpower the world. Sometimes it is how to stop disturbing it long enough to understand it. That is why, for a student of ninjutsu, the forest can still be a dojo.
