I still remember it like it was yesterday. I was 16 years old, sitting in the back seat of my parent’s car thumbing through the latest issue of Black Belt magazine when I came to a full page advertisement for the 1989 Tai Kai with Ninjutsu Grandmaster Masaaki Hatsumi. To my shock and utter astonishment this 3-day seminar with the master ninja and his top students from Japan was being held in the United States. Not only was it being held in the US, but in my home state of NJ, not even an hour drive from my house! Something clicked in my brain – I HAD to go to this thing! Continue reading

This is Dangerous to YOUR Training
Alright. Strap in, kids because this is gonna be a bumpy one.
There is a huge problem that affects many people training in martial arts today that needs to be addressed because it is severely inhibiting their progress and skill. It applies to fitness training as well, so if you don’t train martial art read this with whatever type of training you do in mind. Continue reading
How to Develop Wrists of Steel
Martial arts training, especially in arts like Bujinkan Budo Taijutsu, Aikido, and old school Jujutsu, tend to put a lot stress on practitioners’ wrists due to the various types of wrist locks and throws. Over time this can lead to chronic wrist pain, soreness, and even permanent injury. Continue reading

Destroy What You Are
Lately I feel like a fire’s been lit under me in my training. Somehow through sheer persistence, perseverance, and being too dumb to quit, I feel like I’ve broken through to a new level. And this level is more difficult than the one before. New levels always are.
Sometimes I think people have the impression that if you keep training in something long enough, like martial arts or strength training, then it somehow gets easier as you get better. I don’t think this is true. At least it’s not true for those who continue to push themselves to break limits. Continue reading

Preparing Ninja for a Mission
My name is Ichiro Watanabe. I am a chunin, a middle level ninja of the Togakure clan.
Our small village is secluded deep in the mountains near Mt. Togakushi, otherwise known as Togakure Mountain. I could tell you exactly where, but I’d have to kill you. No joke, it’s a matter of survival for my family and clan.
You see the year is 1601, one year after the famous Battle of Sekigahara which brought Ieyasu Tokugawa to power uniting Japan. There is still much to do, however, and the need for the services of our ninja clan is still very great. Continue reading
