OH MAN! LOL! Are you serious? You aren't ranking mma up there as popular as sumo is Japan are you?
I'm fully aware that Sumo is thier national sport. You won't get me like that. I've been in martial arts, since I was a 5 yrs old. Believe it or not, pro wrestling, k1 kickboxing, and boxing makes out better over there. Linares the boxer has a huge following in Japsn. He's rating's on the tv market over there. It's not that well off as you think. Look up number of events and how much money is generated. MMA isn't superior over there. Does well but isn't top dog. USA is the top market for MMA and it isn't even allowed in one of usa's landmarks, in NYC. LOL! Bigger then boxing? Last time I checked, boxing holds events everywhere. OMG dude.
