Lol. I don’t even know why would a Karate Sensei be strict about Japanese when Karate itself isn’t Japanese martial art.
Well, it originated somewhere in India, I recon. From my understanding, its a "cut out the bullshit - short version" of Chinese Kung-fu, they got it from an Indian dude supposedly.
I wasted almost 14 years of my life studying that crap, I mean, what the hell is it useful for, besides blowing a candle out with a punch? Okay, if I would assault someone (shouting Japanese words while attacking) who does not see it coming, he would go out like the candle, I guess. But any moving target has a decent chance. Thank Vishnu for MMA who showed us the truth.
