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

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.

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?
