源頼家
Asahina's name is associated with some incredible feats. According to the Azuma Kagami, he and future shōgun 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.
