If it was a Japanese man's martial art named after himself, it more than likely would have been "Maeda jujutsu", as "jitsu" is a strange mistranslation by the Gracies.
"jitsu" is the Japanese word for "truth". "jutsu" is the Japanese word for "art".
Even the way most people pronounce "jitsu" is wrong by Japanese standards. It'd be "jee-ss", with a silent "t" and very little emphasis on the "u" sound.
That would be redundant, as you're essentially saying "Brazilian Gentle Gentle Way"...
really only 2 answers that make sense (usa, brazil) and you could have an argument for either one
Canada
This is sarcasm, right?
