Mistake. Ignore please.
i think it's spelled judo
U wot m8?
OP if obviously Korean.
i too have always wondered how the brazilians brought jiu jitsu to japan
Brazilians didn't bring jiu-jitsu to Japan they brought BJJ to Japan.
The mistake was putting in the wrong sub-forum.
The post is on the BJJ sub-forum. But anyway, here:
BJJ and Judo are both derivatives of Japanese jujutsu.
