Along with 'Manyoshu (Collection of Ten Thousand Leaves)' and 'Kokin,' it produced one of the three major styles of poetry--'Shinkokincho' (tone poems seen in 'New Collection of Ancient and Modern Poetry')--and had great influence not only on waka poems but also on the later renga, haikai (seventeen-syllable verse) and yokyoku (Noh song).
「万葉集」「古今」と並んで三大歌風の一である「新古今調」を作り、和歌のみならず後世の連歌・俳諧・謡曲へ絶大な影響を残した。
