Shui shu (abridged form of Shui wakashu) in general has a plain and graceful style, and includes many poems for formal occasions such as ga no uta (poems for congratulations), byobu uta (poems matching with a painting on the byobu, folding screen), and poems for uta awase (poetry competition), and especially includes excellent ones of love, eight of which were selected for Ogura Hyakunin Isshu (the Ogura One Hundred Poets, One Poem Each).
『拾遺集』は総じて平明優美な歌風で、賀歌・屏風歌・歌合など晴れの歌が多いが、殊に恋歌はすぐれ、小倉百人一首に8首も採られている。
