I have seen absolutely nothing in Japanese folklore that remotely resembled the Russian legends about Baba Yaga... Actually The Movie "Spirited Away" did have some Baba Yaga esk twinge to it didn't it.
Karate, Taekwondo, Judo, American Jujitsu, along with a whole list of other styles.
What people don't seem to realize in this country is that there is more to Martial Arts than just learning to fight. More than learning mindless routines, and only the slight hints of the way martial arts is...
