Saleva'a Fuauli Atisano'e, better known by his stage name, Konishiki Yasokichi , is an American-born Japanese former professional sumo wrestler. He was the first non-Japanese-born wrestler to reach ōzeki, the second-highest possible rank in the sport. During his career he won the top division championship on three occasions and came very close to becoming the first foreign-born grand champion, or yokozuna, prompting a social debate in Japan as to whether a foreigner could have the necessary cultural understanding to be deemed acceptable in sumo's ultimate rank. At a peak weight of 287 kg (633 lb) he was also at the time the heaviest wrestler ever in sumo, earning him the nicknames "Meat Bomb" and, most famously, "The Dump Truck".

Yūshō is the term for a championship in Japanese. This article focuses on championships in the sport of professional sumo.
