Emperor Suinin
was a Japanese legendary sumo wrestler during the Emperor Suinin era. Allegedly, in 23 B.C., the Emperor instructed Nomi no Sukune to deal with after he boasted that he was the strongest man "under the heavens." Nomi no Sukune engaged Taima no Kuyahaya in hand-to-hand combat and broke his ribs with one kick and his back with another, killing Taima no Kehaya. It was not modern sumo, but he is regarded as the human creator of sumo. He was an ancestor of Sugawara no Michizane.
