There breakdown of stats on Kakuryu can be seen here. He's a Mongolian, just like the yokozuna, Hakuhou is. He weighs 148 kilos, which translates for us on the English system as 325 pounds. Kind of a lightweight, as sumo guys go.
Meanwhile, I have this friend on Twitter, @kanryuyuu, who is a huge sumo fan and posts pics all the time. I asked if I could repost one of his pics, and he said yes.
Sumo and vending machines. Two things that are oh-so-Japanese. How perfect. Thanks, @kanryuyuu!
