I have seen it done in Japan and on t.v. I don't find the enormous guys appealing but I have seen both Japanese and white Americans who were not fat but had body builder or swimmer type physiques doing sumo wrestling. That was very hot. If anyone has those kinds of pictures please post them.

like these guys..I didn't check them all out, but they are lightweight division...
