I'm assuming that this video is supposed to be some sort of joke or parody. There are several shots in the video where he is doing lousy iaido (some of it clear knock-offs of Katori kata) while wearing armor and giving incredibly feeble kiai. Behind him, his attendants are wearing mock-ups of feudal outfits as well. At one point, he's even riding a horse while his attendants carry his banner in front of him. If the whole thing isn't meant as a joke, then I fear for the man's sanity.

My opinion is, in all likelihood, worth exactly what you are paying for it.
