I had the opportunity to view this video on the Human Weapon vs Ninjutsu and have to say, it was a big disappointment however, I expected it to be prior to watching it. I never did liked the show in the first place or other shows like it. These guys are not real Martial Artists, only tournament fighters, there is a big difference between the two.
One disappointing thing I see often in Japan is the increasing number of what I refer to as "Ninja Enthusiasts". Now, before I go further and to prevent any finger pointing, let me first define what I mean by Enthusiast.
You know who they are, their the ones looking for something, they only show up when there's a rank to be given, they are the first in line to get a uniform patch or steal a photo. They are more focused on appearance and looking like they know more than they really do and training with them can be a real bare.
"Ninjutsu has always been passed down by Ninja who managed to find their way through the midst of confusion and doubt"
