Japanese-Samoan sumo wrestler Konishiki Yasokichi, who was once regarded as the heaviest sumo wrestler in history and was given the distinction of being the first non-Japanese-born wrestler to attain the second-highest rank in sumo wrestling, was a beast in the ring during his career’s peak.

Because of his size, he was called the “Dump Truck.” He was dominating sumo wrestling at the time because he was so big and unstoppable—indeed, all his wins were by yorikiri (force out). When Yosokichi finally retired from sumo wrestling, he went back to Hawaii to have gastric bypass surgery, and to its credit, was able to lose 150 pounds.
