Has any one seen any of the sumo matches on http://www.akibacom.jp/english/battle/? It appears that the girls sometimes strike and grab their opponents breasts.  Does anyone know if these matches are competitive or staged?  Also is their any site to download this company's videos.  I love Asian female fighting the best, but I'm a fan of breast attacks and Asian ladies hardly ever go for the boobs in the competitive matches that I have seen.
