All that is being said there is that the Bujinkan and Budo Taijutsu as it is taught is not Koryu. That does not mean that ryu-ha within Budo Taijutsu are not Koryu just that the Bujinkan and Budo Taijutsu (which comprises 9 distinct ryu-ha) are not Koryu. Budo Taijutsu is Hatsumi Sensei way of transmitting the 9 ryu-ha and it is a modern form of it. (ie. the name) So in effect this has been dealt with, again and again and again and yet again. Budo Taijutsu = Not Koryu but within Budo Taijutsu there are ryu-ha that are Koryu.
Hope that helps!
