Utsunomiya Yasutsuna
Utsunomiya Yasutsuna (1202–1260), sixth head of the Utsunomiya clan, was a senior councillor of the Kamakura shogunate and a waka poet. The son of Yoritsuna by a daughter of Hōjō Tokimasa, he took his name from his cousin Hōjō Yasutoki. In 1238 he accompanied Shogun Kujō Yoritsune to Kyoto and became governor of Shimotsuke, and in 1243 he joined the Hyōjōshū council, on which he served until his death.
Fujiwara no Teika praised his verse, many of his poems entering the Gyokuyō Wakashū. He died in Kyoto in 1260, aged fifty-nine.
