Jitsu

I guess Aegis kind of said this already, but jutsu and jitsu are both Romanized approximations of a word that was never meant to be written with Roman letters. Neither one can really claim to be the "right" one.

 

You're annoyed that people are attempting phonetic spelling of a word from another language? Yeah sorry, you'll get minimal sympathy from me on that one.

 

Judo, jyudo, jiudo, or yudo?

 

Zyuudou.

 

yudo obviously, as the koreans invented everything, including air.

 

When refering to Japanese Juujutsu, spell it with a "u" because no modern Japanese romanization uses "i" for "う."

As for Brazilian Jiu Jitsu, I don't know how they pronounce it. (I have already demonstated my ignorance of Brazilian Portuguese.) -.-
