Hmm, to begin with, I'm not sure what makes this fukuro shinai anything to do with Iaido... but more importantly, to be frank this seems to be little more than a porrly demonstrated version of Kashima Shinryu kata in an attempt to add to a resume. Every result I found up to 5 pages on google was about books and DVDs he has, rather than anything about his training, or even him, really. I also haven't come across any Shugenja (practitioner of Shugendo) being refered to as a "monk" before either.
The Fukuro Shinai is based pretty much identically on the Kashima Shinryu bokuto, and the kata are incredibly similar. To compare:
Sueyoshi even uses the same name that Kashima Shinryu uses (Kumi Tachi/Kumidachi). Oh, and for the record, Kashima Shinryu have used a Fukuro Shinai in their training for the last few hundred years as well, although it is not this one.
