He was a close friend of Fujiwara no Teika and his daughter married Teika's son Tameie. He is also said to have commissioned Teika's compilation of the Ogura Hyakunin Isshu. The collection was originally prepared (in a slightly different form to the present Ogura Hyakunin Isshu) to decorate screens (屏風歌, byōbu-uta, "screen-poems") in Yoritsuna's Mt. Ogura residence in the Saga district of Kyoto.
He was the head of one of the chief poetic houses of the Kamakura period.
