My first sumo was lots of fun. We had a good view of the big boys, including top player Hakuho, seen here flipping his opponent. Lots of butt cheek, aggression, ritual, cheering, and drama. I was surprised to see such a variety of attendees, including foreigners, old ladies, business men, mob-looking types and their girlfriends, and school children.
Many of the star sumo players are foreign, including Mongolian Hakuho and Bulgarian Kotooshu. They are surprisingly flexible, and able to withstand lots of flipping, falling, and even crashing off the stage into the crowd.

I like the way his sash is tied so prettily in the back.
And a nice contrast between ass-baring sumo players and brocade-covered referees. Refined aggression at its most fashionable.
