Ninja History 101: An Introduction to Ninjutsu

Welcome to Ninja History 101. During today's lesson, we'll be examining Spies and Assassins, Ninja Gear, Ninjutsu Weapons and Ninjutsu Training. But first, a brief introduction. Ninjutsu practitioners were called ninja, and they underwent rigorous ninjutsu training to become undercover agents of the powerful lords of feudal Japan.


The ninja served as professional spies and hired assassins for their lords, who were constantly engaged in feuds with each other. The ninja excelled in a wide variety of mayhem. In some ways, they were the forerunners of Britain's World War II commandos and America's famed Green Berets. Like their modern-day counterparts, the ninja were skilled at infiltrating and working behind enemy lines. To achieve the skill needed to stay alive in such a dangerous profession, the ancient spies began their ninjutsu training early in life.

Their remarkable ninjutsu training covered four general areas: ninja weapons, physical and mental training, poisons and special devices, and ninjutsu techniques for espionage and assassination. What seems so amazing to us is the careful thought and study that went into ninjutsu training. Ninjutsu training would almost certainly exceed anything given today to CIA agents or those of other espionage organizations. Great clans of ninja arose who developed the art and passed on its practices. By the time ninjutsu reached its height in the 14th to 16th centuries, there were more than 25 ninjutsu training schools taught by these clans throughout Japan. The sole purpose of the ninja schools was to produce a well-rounded murder machine.

That they succeeded is shown by the remarkable range of the ninja's abilities. Truly, they were the ultimate weapon of their day. Part Two: Ninja History 101: Spies and Assassins

How will you perform at the moment of truth?

What's going to happen to you physically and emotionally in a real fight where you could be injured or killed? Will you defend yourself immediately, hesitate during the first few critical seconds of the fight, or will you be so paralyzed with fear that you won't be able to move at all? The answer is - you won't know until you can say, "Been there, done that." However, there is a way to train for that fearful day.

This week I've asked Robert Borisch to give me a birds eye view on his marketing strategy.

Robert is the head sensei and owner of Tri-City Judo a well-established commercial judo school in Kennewick, Washington. I am very impressed with his highly successful business. Unlike BJJ, TKD, karate, and krav maga, in judo we tend to teach in community centers, YMCA's, and other not for profit outlets. So when I find a for profit judo model that is growing by leaps and bounds, it intrigues me. Below are Robert's raw and uncensored comments spoken like a true commercial martial arts school entrepreneur / owner.

The man who apparently launched a racist verbal attack on U.S. women's kata champion Sakura Kokumai earlier this month in a California park has been arrested following a physical assault on an elderly Korean-American couple in the same park Sunday. Michael Vivona is accused of punching a 79-year-old man and his 80-year-old wife without provocation.

Mynewsla.com reported that a group of people playing basketball in Grijalva Park at the time of the assault recognized Vivona from his previous harassment of Kokumai and surrounded him until a nearby police officer arrived to make an arrest. The incident with Kokumai, who is slated to represent the United States in this summer's Tokyo Olympics, gained widespread notice after she posted a video of it on social media in an effort to increase awareness about the growing threat of anti-Asian racism.
