Why Ninja Skills, Science and Laughter?

Ninja Skills

In dangerous and chaotic times, with the odds against them, the ninja developed a physical and philosophical system of self-protection that allowed them to not only survive but to live safe and happy.


In order to share the life altering lessons of the ninja and overcome any historical, language or cultural misunderstandings, we turned to science and its process of observation, questioning and experimentation.


If it’s not fun you won’t do it, so we make it fun while laughing...a lot. Science shows that when you're engaged and having a good time, your brain processes and retains information faster and for longer.

Explore the seven aspects of self-protection.

Self-protection is much more than grappling, punching and kicking. In the LIVE Ninja Safe programs, you will explore all aspects of self-protection. The seven aspects are areas of focus based on the level of violence in a situation that are also intricately weaved together to create a single perspective to help you live safe and happy.

Before the violence.

The first of the seven, Self Awareness, is concerned with how you perceive and treat yourself in all aspects of your life. This aspect of self-protection affects how others perceive you and can make you either safer or more at risk.

The second and third aspects, Awareness and Prevention, are about recognizing and understanding danger and how and where it interacts with your everyday life.

As violence occurs.

The last four aspects of self-protection are the ones that are needed and used when violence occurs, it is already happening and there is nothing you can do to prevent it.

The fourth aspect, Evasion, does not engage violence directly. It is the ability to avoid an attack while it is occurring. The fifth aspect, Escape, is the ability to free yourself from a violent situation when the attacker is already holding and attempting to control you.

Fighting back.

The last two aspects, Defense and Defeat, are what most people think is self-protection; however, the skills required for these two levels are the most difficult to develop. Defense and defeat are when you actively engage the attacker by using force and skill against them. You are physically fighting your attacker.

Defense is the ability to use force to deter an attacker. The key term in this definition is “deter.” Your actions, whether you are punching and kicking, using pepper spray or any other type of force must be sufficient enough to change the mind of an attacker. This equation can vary greatly depending on the mental outlook of your attacker. That’s why there is one more level of self protection.

The most difficult.

Defeat is the ability to control an attacker when they will not be deterred. It can and usually includes all of the skills used in defense but takes your response to an attack to another level to be able to overcome an attacker and control them.

The skill level necessary to be able to control an attacker in any situation (such as multiple attackers or when weapons are involved, let alone a single attacker) is immense. Not only do you have to contend with the physical and emotional requirements of defending yourself, but you must take into account the legal and moral ramifications of doing so.

What level do you need?

These seven aspects of self-protection are the blueprint for all our products and training programs which are designed to help you learn to live safe and happy.

How far you want to delve into the lessons depends on your life's needs and is completely up to you.
