Is Ninjutsu a Koryu Martial Art?
###
Whether the Ninjutsu is a Koryu martial art is a question I’ve read and been asked many times and there a plethora of opinions about this. A very common cited source for one opinion is Koryu.com and I have been asked my thoughts on this site.
In the interest of full disclosure, at my dojo, Poway Samurai Martial Arts, we practice the samurai and ninjutsu arts of the Takamatsuden as trained under the Jissen Kobudo Jinenkan.
It is important to recognize that despite the tremendous work and research done by Koryu.com and its primary sources of the Skoss’ and Dr. Karl Friday, they specifically state that they “Koryu.com” do not include ninjutsu and some related schools because they “…do not fall into OUR DEFINITION of the koryu bujutsu.” They go on to say “…just because we don’t share the same OPINION doesn’t mean that we are not all doing useful and good training.”
These are the key points. Neither the Skoss’ nor Dr. Friday have ever seen or examined the Takamatsuden related scrolls. Dr. Karl Friday, when confronted with the idea that he should ask Dr. Hatsumi to examine the documents for authenticity himself, said he was unqualified to make such a judgement.
The Kobudo arts of the Takamatsuden, have been recognized as Koryu by serveral Japanese organizations that are qualified to authenticate such scrolls, such as the Zen Nippon Todo Renmei among others.
The schools are listed in the Bugei Ryuha Daijiten, which is a catalogue of Koryu and Gendai Budo and due to its’ meticulous cataloging, formatting style and methods used in creating it, it has become THE standard academic reference for anyone doing research into the field of martial arts.
Basically what you have here are disagreeing opinions not unlike getting a Business Degree. For example, in California, the University of California has requirements that are different from the California State University system. Both are fully accredited but when transferring from one university to the other for the same business degree of study not all credits etc. transfer or are included in the curriculum of each university. Both have their own “opinions” of what a Business Degree requires and while there are differences there are typically more similarities.
