Category talk:Japanese judoka

Untitled

What's this category supposed to cover? I mean, isn't "judoka" the Japanese term for someone who's professional career is judo? Hence, I don't know whether it is literally correct to even include Kano, if judo wasn't his primary source of income. And it definitely seems inappropriate to include people like Seiichi Sugano, who may be considered a career aikido instructor, but had nothing to do with judo except for that he learned it for a few years when he was a kid, and later took some students away from judo.
