I would think that if something like this were going to happen, you'd want it to just be like a recognition from someone who does know japanese well. Such as if a mod (who speaks Japanese) were to notice that in all of whoever's posts their Japanese is very good, they could add a badge or whatever to that person's profile as recognition of their skills. But then maybe some people who are good (or think they are) would get upset if they didn't get one 'cause the mods didn't look at their posts... >.>

Anyway, just another suggestion of how this might be implemented if the idea were to fly ^.^
