The only remaining evidence of this poetry competition is that one of its poems was included in Kokinshū (V:251) with the headnote, ‘Composed at a poetry competition on the topic of autumn’. Hagitani (1963, 115) suggests that the contest should be considered as taking place prior to Engi 4 [904], as the vast majority of poems selected for Kokinshū were composed prior to that year. The absense of any further identifying information about the contest further suggests it was a small-scale private event. Yoshimochi is generally better known for his compositions in Chinese, and this poem is the only surviving evidence we have for his participation in uta’awase.
