"Udaijin Morosukeke Utaawase"

...At that time, three distinctive schools of poetry contests had been formed: the Imperial Court and Imperial Harem poetry contests centered around the three Emperors Uda, Daigo, and Murakami; the literary and private poetry contests by Emperor Yozei and his sons and professional poets; and the secluded pre-ceremonial poetry contests of the regent's family, who had turned their backs on the Imperial Court-led poetry contests. In addition to the above, other representative poetry contests of the time include the Dairikiku-awase (Dairi Kiku-awase) (913, 953), Kyogoku no Miyasudokoro Uta-awase (921), and Udaijin Morosuke-ke Uta-awase (956).

During the reign of Fujiwara no Michinaga under the reign of Emperor Ichijo, individual works such as "The Pillow Book" and "The Tale of Genji" dominated the literary world, and poetry contests were left to desk-based selections made with a critical eye, such as "The First Fifteenth Poetry Contest" and "The Thirty-six Selected Poets," selected by Fujiwara no Kinto, "The Second Fifteenth Poetry Contest" selected by Kazan-in, and "The Thirty-six Selected Poets," selected by Prince Kohira.
