Membership: Join the Musashi Shinobi Samurai Clan, that has been active for over 420 years!


We are open to receive new members!

A person cannot refer to him/herself as shinobi (ninja) without collecting or dealing in information. So, we first ask you to write an article on local safety and security in your country every season.

Then you will learn our shinobi ninpo principles and shinobi mindsets from us. No martial arts knowledge is needed, as our shinobijutsu is a collection of strategic techniques to gather intelligence without being noticed. There are divisions of work, the majority of the shinobi are not martial arts practitioners.

We have been reviving the order by getting new members, and by introducing our traditions and ninja ideas, as well as working to build a bridge of international friendship.

Once you have completed these assignments and know the shinobi ninpo principles and shinobi mindsets, you will be asked to recite an oath of membership into the Order of Musashi Shinobi Samurai, NPO. There is an annual fee of 3,000 Yen or approximately $24 USD. Once you have been accepted you will receive a membership card as shown below:

SDF – Ko-ryu Bujutsu and the Forgotten Language:
In modern martial arts, there is an emphasis on sport and stylize form competition.
The definition of stylized is: depict or treat in a mannered and nonrealistic style
Back when a martial art was taught as a death or life protection method, the emphasis was placed on how effective the technique was. The techniques were not flashy or like something that you now see in movies.
There are many different types of martial arts that are Ko-ryu or Old School. When you research many of these arts, most teach a series of movements called Kata in Japanese or in English as a “form”. Each form had a series of self-defense techniques that were chained together in order to have a method to 1) remember the technique and 2) to practice the technique for muscle memory. The more you repeat the form the more your body gets used to the movement and increases your reflexes or the ability to react spontaneously.
Many of these have a common thread and that being the language of the movements. In order to keep the techniques of the form a secret, the creators of the form would hide the meaning of the movement. On the surface the form would show an obvious technique, but sometimes the secret of the technique would be the reverse of what is shown or portions of the technique would be shown in different parts of the form.
Keys to unlock the form movements you need to know the following:
  1. Knowledge of the weak points of human body
  2. Balance and unbalancing
  3. Speed and timing
  4. Methods to harden parts of the body
  5. Being soft or hard at the right time
Some Koryu forms were complete martial art systems. In order to understand the form, it could take years to fully understand the movements and to strengthen your body to execute the technique effectively.
As a language, each movement being a technique could be referred to as being a letter of the alphabet of the form. Each letter then would be added to other techniques or letters to form words. In time, the words would then be linked together to form a language. Different words from the form can be linked in different ways to create a fluid series of techniques.
Once you understand the language of one form that you have practiced and became a master of, you will then be able to decode the language of other forms, regardless of the origin of the form. Many of them could be from the Chinese Kung Fu and Tai Chi or the Okinawan Karate forms (kata). In time you then become fluid in many languages or in a wide range of techniques!
These techniques have been referred to as: Tai-jutsu, Chin-Na, Okinawa-te and others.


The Shinobi Defense Force is the International in scope with a counterpart in Japan:

The Japanese counterpart of Shinobi One is called the Bobitai. They give seminars on self-defense and survival techniques and teach the Ninshi mindset to protect communities.
The Musashi Ninja Corps calls disaster prevention ninja and crime prevention ninja involved in disaster prevention and crime prevention as “crime prevention”. The Ninja Defense Corps conducts activities such as disaster seminars and crime prevention patrols (ninja patrols) in order to utilize the art of shinobi to contribute to the local community.
Survival is a way of survival in the event of a disaster or disaster. The important thing is to secure safety first, and then to secure the supplies necessary for survival. Ninjutsu has a number of coping strategies that make it possible. Self-defense may also be part of survival, as ensuring safety includes protecting yourself.
If you can secure a safe condition, you need to secure food, clothing and shelter next. There are simple tents called “Nonaka no Maku” as camp methods when traveling, and “Kikatsugan” as a high-calorie meal in an emergency. The thing called “Uchitake” that carries a fuselage is warm like a warmer when you put it in your pocket. Shuriken and kunai are versatile tools. Used for digging holes, climbing walls, prying doors, etc. It can also be used as a weapon in self-defense. There are application methods that use tools for various purposes. In addition, we will procure various things locally in our mission. It can be used even today as a survival method.
The “law of 3” is a good idea to know about disasters. It is considered dangerous if you cannot secure breathing (3 minutes), body temperature (3 hours), water (3 days), and food (3 weeks) within each standard time. There is also a way to remember “3 is 3” for 3 minutes, 3 days, and 3 weeks without body temperature. Ninjutsu includes breathing methods, temperature control tools, filtration of muddy water, and the preparation of emergency high-calorie foods.
Crime is also occurring in the disaster area, and crime prevention measures and self-defense are required. If a ninja is found by an enemy during a mission, he used tactics to escape or protect himself. Even in modern times, self-defense can be used for self-defense.
In order to reduce the damage caused by disasters as much as possible, “self-help” to protect yourself, “mutual help” to cooperate with local people and people around you, public organizations such as firefighting, police, and the Self-Defense Forces, and administrative efforts ” The three cooperation of “public assistance” is very important. The Ninjutsu Defense Corps utilizes ninjutsu to utilize “self-help” and the idea of ​​Ninjutsu to utilize “mutual assistance” for disaster prevention and crime prevention.

Protect yourself by preparing for a disaster at your own home or evacuating in advance in the event of a disaster.
★ Mutual assistance
Local people such as communities and communities cooperate and help each other

Public support such as rescue activities and provision of relief supplies by public organizations such as public aid offices, fire departments, police, and the Self-Defense Forces.
The Ninjutsu Defense Corps is always aware of ninjutsu and trains in case of disasters, and carries a minimum of disaster prevention goods. We also conduct training in camps, etc. with an awareness of disaster survival. We usually run and walk, train our bodies, and collect local information such as evacuation routes. These are “self-help” to protect yourself. In addition, by holding disaster prevention and crime prevention seminars and building a community through training in the ninjutsu class, learning the idea of ​​Japanese will lead to “mutual assistance” in which we cooperate and help each other. Running and walking as training is aimed at the deterrent effect as crime prevention while being weak. Some have registered with disaster volunteer groups to obtain disaster prevention knowledge and information. In this way, the Ninjutsu Defense Corps is working to utilize ninjutsu for disaster prevention and crime prevention.
Is disaster prevention, crime prevention and ninjutsu related?
