Read the history of it please ^ .
This is the martial art that I practiced for a time. Then my teacher made me read the history for part of my next belt test (this was a long while ago, I've already taken and passed). I'm so glad she did. Two of my favorite guys in martial arts are mentioned - Yamaguchi "The Cat" and Mr. Miyagi. Yes, I said Mr. Miyagi. History is cool :3
I'm planning on going back at some point.
Also : Yamaguchi is beast - http://www.gojukai.com.au/gogen_yamaguchi.htm
He killed a freaking tiger in a cage match.
Also : I can't find an Miyagi history b/c everything on the internets is about the Karate Kid... lol
Direct japanese martial arts styles are awesome, I used to practice Shotokan Karate, but I dropped it in place of Judo and Taekwondo.
