Yamato Gō (born 17 December 1969 as George Kalima) is a former sumo wrestler from Oahu, Hawaii, United States.
After a 5–2 score in September he decided to retire rather than face another long struggle back up the rankings, and started up his own restaurant, Kama'āina's, in Tokyo's Roppongi district.
[1] Although Yamato never rose high enough in the rankings to face a yokozuna in tournament competition, he once defeated Takanohana eight times in a row in training.
His brother Glenn, one year younger than George, also joined Magaki stable two months after Yamato, competing under the shikona of Ōnami 男波 (later Wakachikara 若力).
A third Kalima brother, Kalani, was also interested in joining sumo but was unable to find a stable and instead became a practitioner of Hawaiian martial arts.
