I notice that both http://www.ninjutsu.com and http://www.ninjitsu.com offer home study courses in ninjitsu. The latter seems to be a newly created art but the former, offered by Richard J. Van Donk (10th degree in something and 12th degree equivalent in Bujinkan, apparently), appears to be a course leading to up to 4th degree black belt that the web site gives every appearance of being authorized by Grandmaster Masaaki Hatsumi.
Is it the case that Mr. Hatsumi (I seem to recall that perhaps it's Dr. Hatsumi?) has authorized a home study course in ninjutsu, or is Mr. Van Donk acting on his own? I'm also a bit confused by his ranking--I gather he interprets his menkyo license as being the equivalent of a 12th degree, but then I am unsure what he is 10th degree in and am a bit surprised that such a high-ranking individual isn't e.g. a Hanshi (above the Shihan he claims).
