Other thing I noticed, jiu-jitsu is NOT Japanese, that's something American and Brazillian. Jujutsu is Japanese. The spelling matters as they are 2 entirely different words and actually define styles of jujutsu from eachother these days.
From what I've been able to find out The "i" in Jiu-jitsu represents a chinese influence in the art. Not entirely sure if thats correct but I thought I'd chuck it out there and see what happens.
I'm also new to this forum thing and don't know how to get this writing out of the quote box
