When you mentioned Bobby Ologun in class today I immediately thought of another entertainer who seems to parallel Ologun very closely named Bob Sapp.  Sapp is a massive black fighter who has quite a mediocre record but was very popular in Japan when Mixed Martial Arts was popular there in the 90s and early 2000s and he still is something of a celebrity there, I think.  His main drawing power came from his imposing physique (he is MASSIVE), brute-like fighting style and his very goofy, "simple" demeanor, which strikes me as very similar to that of Bobby Ologun.

Anyway I just thought I'd bring this to your attention if you weren't aware of him--my guess is probably there are more than just these two as well as I'm sure you know better than I.  This trend of huge, black simpletons would seem to bespeak a pretty profoundly racist view towards blacks in Japan, if I am not overreaching...
