Who is this man? この人誰？

On July 17, I took this photo from the bus taking Mordecai and me from Narita to Yokohama. I noticed journalistic frenzy surrounding a relatively built man; I figure he is an athlete of some sort, but because you can't enter images or objects into Google yet, I have no idea who he is. Maybe he's related to K-1, MMA, fighting stuff? He's got that look in his eyes, and either a scar or birthmark near his left eye. Or maybe he's just a famous sailor/seaman?
