Don Roley,
First i will ask that you don't use Ashida Kim's name in reference to Ninjukai,i understand you were using ashida as an example and can understand why you would but i did find it a little disrespectfull (not trying to be funny either) i love a good ashida kim joke as much as anyone.
Second when i said "most history was written by the Samurai" i worded that badly and put it into a bad context. I mean to say that the Samurai wrote much of ancient Japanese history in regard to 'warfare' and 'combat' methods and philosophies.And i meant to imply that the Ninja didn't keep alot of recorded history,compared to the Samurai. That is still worded badly but i hope it makes more sense than the last attempt and you can see where i'm coming from.
I am not "Questions" nor do i know the guy. Now he stated that there is an existing Dojo for "Ninjukai Taijutsu" in Kyoto,Japan. He said that it still exists today.That is not true at all and i dont know where he got that information from, i remember he also gave you names of a couple of books which have reference to Ninjukai which i am also unaware of and no one at the Hombu Dojo in Perth knows anything of the sought either.So i dont know what his sources were/are.
Shihan John Ang learnt the style of Ninjukai through Akito Yashida,Akito learnt it through Jushin Oshima who opened the first school in 1924. Now before i go further, John Ang has never once claimed to teach Ninjutsu,the style he teaches is a style that which he says was the fighting styles of the Japanese Yamabushi in which he was once taught.
The belief of the art's history doesn't run through everyone in the organization simply because not everyone cares about the history,they study the art because of its great techniques and practicality.I am different I am big on History and unfortunately i dont have any rock hard evidence that will satisfy you only the words that i have heard from John Ang and other higher members in the Dojo.However i will do my best to provide you with some information...
After the War many Dojos,buildings,temples and the like were destroyed,including the so called Dojo for Ninjukai (i know that sounds conveniant for my side of the argument) and as you know martial arts of most kinds were banned and some styles were almost lost completely.Jushin Oshima was a naval captain and towards the end of the war he decided to save the art and took it to Malaysia where it found its new base.
I have seen photos of John Ang during his training with a few others in Ninjukai Taijutsu and they are in the Hombu Dojo in Perth.There is also an outside pic of an old dojo (not sure if it is in Japan or not) but i would say no its the one that was in Malaysia. Now when i first started Ninjukai i too questioned the history and the techniques,and thought John Ang could have easily moulded a few arts together to create Ninjukai because of his extensive Martial arts background. The weapons used could have come from a karate background also such as the katana,tanto,sai,kama and Bo's. But then theres also Kyoketsu-Shogei,Kusari-Fundo,Kusari-Gama, Shuko and Shuriken. Some of those weapons were strictly used by the Ninja.The stances used in Ninjukai are also very similiar to Ninjutsu as well as walking and movement styles such as Yoko aruki and Nuki ashi.
You could say that John Ang read a few Ninjutsu books then made up some techniques for the weapons and bang! there you have a shuriken throwing ninja!And i also thought about this theory and the legitimacy with John Ang and his art.But i have seen Ninjukai in action and it is far too well created to be made up from thin air or a few books.The techniques have great practicality and are very fluent in movement. Nothing like the karate i have previously trained with.The 'yin' side of the art is also very well taught and practiced and students can gain good spiritual concepts and theories that can be applied to the taijutsu side of Ninjukai.
I'm not sure why Shihan Ang doesn't paste his old photos on the website or writes a book about the art,There is also some very old Kanji scripts in the dojo that make references to "ninja" but again this could have been "created".I personally believe in the art for what it is.And Don i'm not trying to convince you because all i can provide you with is 'words' from myself and others i have no solid evidence that backs up anything i say,so in that regard you have every right not to believe in the art or anything to do with John Ang and Ninjukai.
I believe in Ninjukai as much as i do the Togakure-Ryu Ninjutsu Tradition but because i have no evidence or historical backing i am fighting a losing battle.
I could ramble on and on and defend the art more and more but i have better things to do as do you Don,i appreciate it if you took the time to read this much so i wont test you're patience any further

...
We have debated all this in the past and i'm sure there will be further debate,but from my side it is pointless so that is why i will respect you're decision not to accept the art as a TRUE ninja fighting art.And i wont try to convince you further.I just want to learn from people like you and develop my knowledge of the Ninja.I look forward to joining the Bujinkan next year to compare styles and see what Ninjutsu is compared to Ninjukai Taijutsu.
much respect
