Asahina Yoshihide (朝比奈 義秀?), also known as Asahina Saburō (朝比奈 三朗?), was a Japanese warrior of the early 13th century, and the son of Wada Yoshimori. His name (also written with the characters 朝夷奈 (Asaina?)) comes from Awa no Kuni's (安房?) Asaina-gun (朝夷奈郡?), where he lived at one time. Though very likely a historical figure, Yoshihide appears in literature and in kabuki as a somewhat superhuman legendary character. According to these, his mother was the renowned female warrior Tomoe Gozen, and he had superhuman strength which he used to accomplish a number of stunning feats.
Asahina's name is associated with some incredible feats. According to the Azuma Kagami, he and future shogun Minamoto no Yoriie, who were good friends, one day were together in Kotsubo. Yoriie said he had heard what a good swimmer Yoshihide was, and challenged him to give a demonstration of his prowess. Immediately, Asahina jumped into the sea and soon re-emerged with two or three sharks in his fists. Asahina is also mentioned in the Soga Monogatari as having competed for strength with Soga Goro Tokimune.
