Here's a fun little clip that's popped up in a MMA forum (of all places). It seems to be getting some air time due to Tanoyama "unusual strength".
It's interesting to watch his fights. Being so obviously under-weight (compared to his opponents) means Tanoyama is pretty fun to watch. Perhaps not quite 'pure water' (IMHO), but he moves, throws, clashes and redirects like someone who means business.
Wow! One of the best sumotori I've ever seen. Quite unusual to see a foreign sumotori who is so..almost slim! Looks like he's really mastered the art. He should make yokozuna.
