Even for a sumo wrestler, Kaido Hoovelson looks big. The 20-year-old Estonian, who goes by the ring name of "Baruto," stands 197-cm tall, making him one of sumo's tallest wrestlers.

Last time he checked, he weighed a solid 162 kg -- "166 after dinner."

Behind the table of a pokey Ryogoku bar, he takes sips from an oddly small looking glass of beer and recounts the first bruising year of his sumo career.
