He emerged as an important poet in an early uta-awase or poetry match, Koresada no miko no ie no uta'awase (是貞の親王家歌合, The Poetry Match at Prince Koresada's Residence, c. 893), and was involved in many of the poetic activities of the day, including a position as a compiler of the Kokin Wakashū.[2] A collection of his personal poems appeared as the Tadamine shū, though more than half of it is not certainly canon. He is also famous for the Tadamine Juttei (忠岑十体, Ten Styles of Tadamine, c. 945), an influential work of Heian criticism.
