He's a yokozuna. Winning every basho 15-0, regardless of physical condition, is a job requirement.
He's also supposed to be a model citizen, showing absolutely no emotion on the dohyo, and never ever do things like shove opponents or perform henka.
And no, I'm not exaggerating.
Bravo. That's precisely the point.
It's a good point, but every sport needs to get into the 21st century and if you don't want your Yokozuna to be influenced by modern way of life, you should either not promote non-japanese, not allow non-japanese to even be in sumo or lock the potential yokozuna in a cage while he is in sumo. The world has developed and as traditional as this sport is, you can't expect sane, normal human beings to behave like they used to 200 years ago...it's just not natural to anybody! There is more competitiveness today and less respect and I think that makes sumo more interesting to non-japanese! By the way I can't agree 15-0 is a job requirement for a Yokozuna - that certainly diminishes completely the ability of all other wrestlers and that is just idiotic!
IMHO, we do not have sources trustworthy enough that describe Yokozuna life 200 or even 100 years ago. Yellow media is also product of late XX, so even if there were impropery behaving Yokozunas in the past, their deeds will vanish into the shadows of history...
